Designing a disaster recovery system requires planning and consideration of the
available options that will best fit your company’s needs, SLA and budget.
This guide will help you design an Exchange Disaster Recovery plan in conjunction with
SANRAD Replication.
The guide assumes that you have basic knowledge of SANRAD V-Switch and Exchange
Administration.

Exchange Disaster Recovery Planning

This section discusses both general and Exchange specific considerations that need to
be addressed when designing a disaster recovery solution combining SANRAD
replication and Microsoft Exchange Server.

General Considerations

SANRAD replication solution allows for flexibility with Exchange Disaster Recovery design.

The most influential factors affecting design consideration are:

• Budget limitations

• Recovery Time Objective (RTO) requirements (the time until the data is back online)

• Recovery Point Objective (RPO) requirements (the amount of data that can be lost)

• Network bandwidth between the local site and remote site

• Replication method: Synchronous versus Asynchronous

• Replication frequency (only for Asynchronous replication)

• Initial volume synchronization

RTO (Recovery Time Objective)

• With high level RTO, duplicate hardware is required to allow quick recovery making
the solution more costly.

RPO (Recovery Point Objective)

RPO requirements are best defined by the amount of data that the company is willing to
lose.

• High level RPO requires more bandwidth for both Synchronous and Asynchronous
replication.

• Low level RPO requires less frequent replication and increases the risk of losing
more data.

Network Bandwidth between the Local and Remote sites

Bandwidth between the sites is generally the most crucial factor affecting the replication
component of a Disaster Recovery solution.

• T1 (1.5Mb) links impose less frequent data replication and the use of asynchronous
replication methods.

• T3 (45Mb) links or a 1Gb links allow frequent replication and the flexibility to choose
between synchronous replication or asynchronous replication methods.

Replication method

When considering which replication method to choose it is important to remember:

• In Synchronous Replication the I/O commands are written to the local disk and to
the remote volume at the same time. Every IO command requires an
acknowledgment from both the local and remote sites before the next command.
Consequently, synchronous replication is best deployed with a high bandwidth
connection in order to allow the remote acknowledgment to arrive back to the local
site as fast as possible and the replication can run faster.

• In Asynchronous Replication the I/O commands are written to the local volume and
local journal volume which in turn is replicated periodically to the remote volume as
periodically defined by the user. Consequently asynchronous replication can work
well with lower bandwidth (minimum recommended for Exchange replication is 1.5
Mb) since both acknowledgements are local (from the primary volume and the journal
volume) and thus the replication is fast by default.

• For Asynchronous replication, you must decide the data replication frequency. There
are three factors that must be considered:

1. The size of the network bandwidth between the sites.

2. The amount of data changes that need to replicate each time.
For example, large amounts of data changes take longer to replicate using T1
links.

3. The RPO requirements.

Initial Volume Synchronization

SANRAD replication solution can be used to protect existing production Exchange data.
SANRAD Disaster Recovery solution supports both online and offline synchronization.
When using SANRAD replication with existing Exchange data, an Initial synchronization
of the Exchange volumes on the local site to the remote site must be performed.
The initial volume sync method depends on:

• The size of the volumes needed to be synchronized.

• The network bandwidth between the sites. For example, the bigger the volume size,
the longer it will take to synchronize over a T1 link.

Online synchronization starts immediately when replication is started and uses the
same network link that will be used during the replication.

Offline synchronization is a manual process where SANRAD replication prepares the
volumes on the primary site and the user must copy the data to the remote site. It is the
user’s responsibility to make sure the volumes on the remote site are synchronized.

Exchange Considerations

Any Exchange Disaster Recovery planning should (at the very least) consider the following
requirements:

• Quick access to the most recent copy of the Exchange database and the transaction
logs. In a disaster situation SANRAD replication provides fast access to the
replicated data on the remote site.

• The Exchange database and its related transaction logs must be replicated together
to the remote site. SANRAD replication uses consistency groups to ensure
simultaneous replication of all volumes assigned to a consistency group.

• Exchange is integrated into Active Directory. An Active Directory domain controller
(running Global Catalog) which is part of the same Active Directory domain that
exists in the primary site, must exist in the remote site as well (or at least the
capability to rebuild one and reconnect it to the existing Active Directory Domain).

• The most up to date replicated copy of the Windows backup set (which includes
system state) to expedite Exchange Server recovery.

Note: for detailed information about Exchange 2003 disaster recovery considerations
please read Microsoft’s article, “Exchange Server 2003 Disaster Recovery Planning
Guide (http://go.microsoft.com/fwlink/?LinkId=21277)”.

This guide deals with designing a disaster recovery system while planning and considering the
available options. It further discusses about suggested Disaster Recovery Designs, fully Mirrored Remote Site, partially Mirrored Remote Site,
small Remote Site, combining SANRAD Disaster Recovery Designs with Exchange Disaster,
restore Models, restore Exchange with a Standby Server and restore by Rebuilding Exchange Server.

Only a few decades ago, if you knew how to use a multimeter, you were probably an electronics technician or an engineer. But, today, the handy test equipment known as a Digital Multimeter should be in the toolbox of every handyperson. The multimeter is great for determining the working status of many appliances. Multimeters are available in either digital or analog models. Digital multimeters will display readings in numbers. Analog multimeters indicate the value with a needle over a scale.

Have you ever wondered why a light doesn’t turn-on. If the lightbulb is not bad, the lamp may be out of order? Is the lamp cord bad? Here is one simple example where a digital multimeter comes in very handy. A useful function of a multimeter is the resistance, or “continuity” test function. To avoid the chance of electrical shock, it is important to never use the continuity test function on any appliance that has live voltage connected. Always make sure the appliance is first NOT connected to any power source.

Now with the power disconnected, set the multimeter dial to Resistance (Ohms). Touch the two test probes together (one is Red “positive”, the other is Black “negative”). The OHM meter reading will indicate zero resistance. When there is zero resistance, you have continuity. A reading of zero indicates the circuit is closed and the circuit can conduct current. Now for an easy first test, take a standard lightbulb out of a lamp socket. Touch one test probe to the bottom of the lightbulb, and touch the other test probe to the threaded side of the lightbulb socket. If you read continuity, or zero resistance, the lightbulb is good. If the meter does not indicate continuity, then you know the lightbulb interior filament is broken (current can not pass through). The same test can be performed on two ends of a simple electrical cord. If the meter does not indicate continuity, then there is a break in the circuit, and the cord is probably cut. Remember to never test the continuity of any cord or appliance with the power on. Always first disconnect any power or current source.

To test a switch, place a test probe on each side (pole) of the switch. When you move the switch from the off to on position, the multimeter reading should change from zero to infinity. If not, then the switch is not working properly. To test a motor, touch a test probe to each pole. Again, a reading of zero indicates that the motor has continuity, current can pass through, and the motor windings are good.

After carefully studying the instructions of the digital multimeter, you will be able to move on to more detailed electrical tests. A multimeter can measure alternating current (AC or household current) or direct current (DC or battery current) in a live circuit. It can also check voltage. A multimeter can test 120 volts AC in a home circuit, or it can test DC batteries to learn if they are weak or fully charged.

Take the time now to learn how to properly use a basic multimeter. You will be glad you did when someday you would like to verify the cause of an everyday electrical problem.

A basic digital multimeter is available at http://CableOrganizer.com for as little as $8.00 and up, depending on your test requirements.

Java is a high level object oriented language. When we compile java code it first gets converted into highly efficient byte code by the java compiler. The generated byte code is then interpreted by a peace of software called java virtual machine.

What is java virtual machine?
Java virtual machine is the software which interprets compiled java byte code and runs the java program. Java virtual machine is also known as JVM.
As Java code is first compiled into byte code and then the java virtual machine interprets and runs the code, java has achieved the platform independence. Java virtual machine is available for almost all the platforms, right from windows to various handheld devices.

How Java Virtual Machine works ?
JVM does not have any information regarding the programming language. It knows only binary format of the byte code. The class file generated by the java compiler contains the byte code in the format which JVM can understand. We can generate the byte code that adhers to this format in any programming language.

Every java program must run within the boundries defined by the JVM. The code run inside the JVM can not go beyond the security constraints defined by the JVM. This is one of the reason why java application are considered as secure applications over internet.

What are citation machines? As per definition, “citation machines are web tools designed to assist teachers/ writers in modelling the proper use of information”. It may look as a complete definition to the common reader – but it actually does not say much. The first time someone mentioned “citation machines” phrase to me, I was stumped. And I am a regular user of the net, with a moderate knowledge of the Internet and surfing. So, in order to understand the term, ‘citation machines’ better, I decided to dig a little deeper and see if I get more clarity on its definition and uses.

I found out that what makes the today’s citation machines, was first the brainchild of David Warlick who designed this web tool in October 2000. It has been re-designed with a major facelift in January 2004. The main reason for which it was first brought into existence was to systematize the use of information, but it slowly turned a very useful tool to control plagiarism. It is nowadays used by writers specifically to prove that the material they have used is not plagiarised – which is course is very tempting with the open use and access to the million of resources on the Internet.

It seems the citation machines are very easy to use and are a delight to the writer because of their versatility and fantastic knowledge resource base. It also makes one understand documentation process. In order to get the best from the citation machines, you have to choose carefully whether you are using print material or electronic material. IT usually guides you through a menu where you indicate your choices after which the citation machines give you the possible resources. You may use as many as you need.

You should be careful about while using the citation machines with regard to the accuracy with which you fill in the required blanks. If you leave too many without answer, the accuracy of the result from the citation machines will be very poor. Another important point to feed is which literary method of writing you are following, i.e. MLA (modern languages association) or the APA (American psychological association). When the citation machines throw up the results, if you have filled in the information correctly and as exhaustively as possible, you will need very little formatting.

It if very difficult to really format the results afterwards, so it is a good thing if you review the information entered before you enter the search. “Show My Citations” button will help you check and verify your results with your work. It is important here to note that once a citation is submitted and it cannot be changed.

Remember to save your work in word file after checking out the citations thrown up by the citation machines.

The citation machines are extremely useful when one needs to submit a professionally written article, or report. It is fast, convenient and very exhaustive in its resources. As I mentioned earlier, today it is also used as an anti-plagiarism tool as it indicates the sources used for any information given, in any article.

What is a flexible way to market or celebrate an occasion that will impress those around you? It may sound silly, but what I’ve found is that finding a good post card printing company can be of great help to you in many ways. You can market your business, celebrate an occasion in a custom manner, or even remind business associates of meetings and upcoming events. Custom post card printing is a service you should certainly seek out and take advantage of.

If you are a business owner, you know that recognition is one of the most valuable things you can have. You know that if people know about you and recognize the name they are certainly more likely to use your business. This is where custom post card printing comes in. If you can find a good company to print post cards for you, they make a fantastic and inexpensive marketing tool. Send them out in mass mailings, hand them out at local events, or post them on public bulletin boards. The way you get them out is up to you, but they are handy and can be very informative. When having your customer post card printing done, make sure you have a picture of you or your business, the name, contact information, and maybe even some sort of coupon to bring in the business. You will find it to be a valuable tool, and the best part is that custom post card printing is not all that expensive.

A second use for custom post card printing is to help with a celebration. If you are throwing a birthday party for a friend or relative or putting together an open house for someone’s milestone anniversary, sending out post cards with the invite can be easy and inexpensive. Custom post card printing will allow you to put a picture of the birthday person or happy couple on there along with the information regarding the celebration. All without the envelopes, the stenography, or any of the other hassles that can come with such events. It isn’t as formal, but the ease of the process will be appreciated by most.

Thirdly, use your custom post card printing as a way to get out reminders. In this age of emails, we sometimes forget how effective a nice mailed reminder of an event, conference, or important meeting can be. Your dentist or doctor send you post card reminders, why shouldn’t you do the same for your business associates? Custom post card printing isn’t expensive and it can assure you good attendance.

With the flexibility and creativity that a good custom post card printing company can provide, you should really consider using one. It is something you can make use of in your business, personal life, or even business associations. By increasing business, putting together a great party, or making sure there are plenty of former customers at the conference you will see that custom post card printing [http://www.bassettnews.com/category/computing-comments] can be a huge help to you in your life.

If you are a busy medical professional like I am, then you know that you don’t always have the time to run and reference a medicine or diagnosis.

Hence, the PDA and dedicated medical software. I use a software program called EPOCRATES. Its available as a free download from the epocrates site at (www.epocrates.com) with limited use or you can purchase the full Essentials software package as I have done.

Epocrates Essestials is the all-in one mobile guide to all of the drugs, diseases and diagnostics you could ever need. It supports the OS 3.5 or higher palms and needs about 8 mb of available memory. It also supports the Microsoft Pocket PC platform and only requires about 6 mb of available memory. It will also support the Windows 98/2000/ME/XP platforms with palm desktop 3.1 or higher.

Each time you cradle your PDA it will be updated by the epocrates site. The Essestials program offers you over 3,000 brand and generic drug monographs with most all of the health plan insurance formularies. It also offers you the ability to multicheck multiple-drug interactions. It has an ID infectious disease treatment guide, 400 alternative medicine monographs including interactions with drugs, Clinical tables and guidelines, Medical Calculators, IV compatibility checker, diagnosis and treatment for more than 1,200 diseases and conditions,
Selection and interpretation of literally hundreds of diagnostic and laboratory tests, and the ability to cross reference drugs, diseases and diagnostics. What I really like about the Epocrates Essentials program is the fact that all of the ACLS and PALS algorhythms are at your finger tips. Visit the Epocrates site and download some of the freebies they offer and evaluate the software if you are a busy medical professional who would like to have most of the references, medications and diagnostics at your fingertips.

The other program I use is called PEPID. You can also get a free download from them on their site, WWW.Pepid.com.

This program too is a very comprehensive medical software program for the PDA. I use the ED module in the Emergency room where I work as a nurse. This program allows me to have a complete emergency medical database, containing instant answers to questions on diagnosis, treatment and disposition. It covers over 2000 medical topics and has some 5,000 drugs including prescription drugs, OTC and herbal medications. They also utilize over 250 medical calculators which are fully integrated. They also utilize International Comprehensive – SI and American lab units and calculators. They display more than 1,900 diseases and trauma topics with diagnosis, pathophysiology, treatment and disposition.

The list for this software package is endless but is extremely powerful and gives you much much more bang for the buck then anything else I have seen in 25 plus years of being a nurse and working in the Health Care field.

If you are as busy as most of the Doctors and Nurses are today and you really need to be on top of your game, then I would invite you to check out these two sites and decide for yourself, as I have done, which of these programs, if not both, will best suite your needs. I use both and find most of the ER docs asking me questions because I am able to quickly look things up with the PDA.

People who are about to build their first computer will start by doing a bit of daydreaming. Their minds will conjure visions of the perfect machine, that blend of CPU, motherboard, and hard drive that will give them blistering speed, conquering the toughest tasks effortlessly. They see it sitting on their desk, the case a thing of beauty, an artwork belonging in an exhibit of modern design.

Then, they check their bank account. Reality sets in. Corners will have to be cut. They will scour the earth (well, the internet) for bargains. Perhaps, with a lucky find or two, they can still pull it off.

After a bit of looking, it seems they are in luck. A well known parts supply house is selling one model of case dirt cheap. But is it a bargain? Or is it the worst piece of luck they’ve ever had?

To decide, the builder must first prioritize their needs. The first, and most obvious, is the case’s form factor, or size. Most of the computers I build are full sized ATX’s, and I build them in a mid or full tower case. But you might have your heart set on building a microATX cube. Smaller cases tend to have more problems with cooling, but this can be overcome.

Second, is the power supply. Does it come with the case, or must it be purchased separately? If it’s included with the case, will it be big enough? To decide, please reference my EzineArticles.com story “Computer Power Supply: How Much Is Enough?”. As a simple point of reference, if you are building a gamer with a super fast chip, and monster AGP card, figure on a 450 watt supply.

For the unit we assembled in my book, we were able to get by nicely with a 300 watt supply, by doing some careful planning.

Next, are there enough fan ports? The more ports available, the better off you are. A standard configuration will have two in the back, one for the power supply, one about midway, and one in the bottom of the case. Some cases are now coming out with three ports in the back.

Another feature I always look for are USB and IEEE 1394 Firewire ports in the front. This is very handy if you have a digital camera, and want to download photos, or video. Of course, if this isn’t available in a particular case, retrofit kits are available for use in a 3.5 inch bay.

According to the research firm Frost & Sullivan, the estimated size of the North American used test and measurement equipment market was $446.4 million in 2004 and is estimated to grow to $654.5 million by 2011. For over 50 years, companies and governments have procured used test and measurement instruments in order to realize a number of benefits including the need to:

  • reduce equipment acquisition costs,
  • replace discontinued testing instruments,
  • circumvent lengthy new product delivery times, and
  • conform to legacy standards and specifications.

Although there are many considerations when purchasing used test and measurement instruments, the quality of the instrument and reliability of the vendor should be at the top of the list. Used test equipment vendors deploy a number of bywords that represent the equipment they sell, including “refurbished”, “remarketed”, “reconditioned”, “rebuilt” and, the obvious, “used”. These marketing adjectives typically imply various quality processes and buyers of used test equipment should execute their due diligence prior to purchasing.”Used” or “Remarketed” equipment often describes products sold with an “as-is” supposition. You might purchase used equipment from an end-user organization or auction company that is selling surplus assets. Products sold as “used” should be priced at the lower scale of the market spectrum and it is not uncommon for quality issues to arise with “used” equipment. It is likely that the instruments have not been tested and have an uncertain history. It is only prudent to purchase “Used” equipment if you have the in-house repair and calibration facilities/expertise and are able to procure the item at a cost low enough that the added expense of repair and calibration remains to be a positive, economical outcome.

“Refurbished and Reconditioned” are akin and are the most common presentment of used equipment from equipment dealers. Refurbished equipment is fully tested and calibrated to NIST standards to assure that they meet the original manufacturers’ specifications. Refurbished equipment should come with all standard accessories and operating manuals. Malfunctioning internal components will have been replaced or repaired and the product will have been cosmetically cared for including painting and the replacing of face plates, button and knobs. Refurbished equipment is typically sold with a 30-90 day parts/labor warranty and is priced in the middle to high-end of the market spectrum.

Finally, some vendors advertised “Rebuilt” test equipment. Many instrument options are field-installable and can be built-to-order according to the customer’s requirements. Some products can even be converted from one generation or version to the next by adding various components. There is absolutely nothing wrong with purchasing rebuilt equipment and, in fact, if you can not find the exact product configuration you are sourcing, you should ask qualified vendors about the possibility adding those options. As with used and refurbished equipment, always exercise caution in choosing a vendor. Assure that the vendor is qualified or uses a qualified electronics laboratory to repair, calibrate and rebuild the products you seek.

Purchasing used, refurbished or rebuilt electronic test equipment is a great way for organizations to save 30-70% on their asset acquisition costs. Warranties and guarantees from used test equipment vendors are formidable. In select product groups, the original equipment manufacturers offer extended warranties in partnership with the vendors that are the selling those products.

Exercise caution and perform due diligence on your vendors. It is most effective to first identify a qualified used equipment vendor and begin a supplier relationship, as opposed to sourcing each instrument you need individually. If your qualified vendor does not have what you are looking for in inventory, it is likely that they will be able to locate it within 24 hours. By first identifying and working with a select few vendors, you will assure consistent quality and economical pricing with every used test equipment purchase.

Robert Preville is the President and CEO of Global Test Supply, LLC, a distributor of new and refurbished test and measurement equipment from manufacturers such as HP, Agilent, Tektronix, BK Precision, Instek, Promax and Rohde & Schwarz.

It is amazing how fast we go from one computer to the next, needing more memory, more speed, but never finding enough. It is this demand that keeps the computer world humming along well past many other products on the market. Each new model that comes out has a new feature, a new gadget to go along with it. But, what type of computer do you need is the real question. To answer it, we need to explore what we use these fast running machines that have taken over our lives so quickly.

For many, it’s the computer’s programs that we need so vitally. Programs are what make our lives easier after all and having the perfect ones to organize, design, and basically work for us is just the way of the world these days. Some programs run with higher demands for memory and internet capabilities. In order to have that, yes, we need yet another fast moving machine to sit on the desk.

Other features that have become vital to computers in our lives include the wireless industry. Remember the thrill we all had years ago when the first wireless phones came out? Now the trend is for wireless keyboards and adding a wireless mouse doesn’t hurt either. Others include features for burning CD’s and watching DVD’s. There are probably hundreds of additional features not listed here.

Even more important has become the overall look of the computer. Just as televisions have, computers have slimmed down monitors with LCD screens that make images clearer and more real life. The demand is huge for laptops that can be carried from place to place often being thinner than most people’s daily planner.

Encompassing all of this, it is up the each individual to determine his or her needs in a computer. Just like anything else within our lives, we all want the biggest and the best. But, it can be costly to have all of these features. Instead, chose the ones that fit your needs the most. Then comparison shop for the right company. Computers are a way of life, there is little doubt of that. To keep up to date, you might want to head over to that internet warehouse full of potential computers for your desk. Hey, you might even get to build your own!

CCTV surveillance systems play an important role in fighting and preventing local and international crime. These closed circuit television systems were in place in London before the July 7th bombings and this footage is being used to identify suspects and investigate the attacks.

Besides fighting terrorism, CCTV security systems installed in public places or retail markets can deter crime, provide the police with leads, help citizens feel safer, and improve the economy of a crime-stricken area. Most CCTV systems have now gone digital for improved performance, surveillance camera maneuverability, and quicker feedback as compared to analog systems.

Implementing CCTV systems

Law enforcement or security professionals best support CCTV systems. These teams of professionals need to monitor the CCTV video evidence on a timely basis and they need to be properly trained in order to interpret suspicious behavior caught on the system. When all of these factors are in place, then the CCTV security system will be effective for keeping citizens and shoppers safe.

In the case of some municipalities or businesses not being able to afford all of the necessary components of a CCTV system, many CCTV providers can recommend a scalable approach so that priority security needs may be addressed first. Then, additional surveillance cameras can be purchased in succeeding years as the budget allows.

Digital CCTV systems and surveillance cameras

A modern digital CCTV security system consists of hardware and software components that collect and transmit vital surveillance camera information over fiber optic lines to control rooms staffed by security professionals and equipped with digital CCTV monitors. An example of the surveillance cameras used for reducing crime in LA’s MacArthur Park include CyberDome DayNite 25X cameras equipped with removable infrared cut filters, 25x optical zoom lenses, 12x digital zoom capabilities, and 360-degree PTZ (pan tilt zoom) capabilities. This MacArthur Park system also includes GE Storesafe DVRs (digital video recorders) and GE KTD-405 keypad controllers. DVRs are capable of saving CCTV data to a PC for up to ten weeks of recording and some even feature motion detection technology, which means that the footage is only recorded when motion triggers the DVR system.

Digital surveillance cameras range in type from compact, fixed cameras to direction-controlled models that can see in the dark under various lighting conditions. CCTV decision-makers need to know what kind of job each surveillance camera must fulfill. Will it watch the flow of passersby (fixed cameras) or will it need to monitor a crime-targeted area (dome cameras with PTZ functions)? These video security managers also need to consider weatherproofing their surveillance cameras if the cameras are mounted in an especially hot or cold climate, or if the viewing fields could be obscured by dirt or dust.

What kind of crimes do CCTV systems prevent?

Evidence has shown that CCTV systems mostly deter property crimes and robberies, but not more violent crimes such as rape and aggravated assault. CCTV systems may not catch these crimes because they may occur away from the surveillance cameras in more deserted areas. Fortunately in most situations, when a CCTV system is in place, criminals generally shy away from these monitored areas fearing prosecution since these recorded images can be used in court. As noted previously, in order for a CCTV system to be effective, the electronic system must be used in conjunction with human know-how and skills and it should be carefully integrated into existing security plans.

CCTV: Looking ahead

In the next few years, digital CCTV systems will evolve into wireless CCTV systems that employ GSM (global system for mobile communication) or 3G (third generation) connections. These wireless systems are completely portable and can deliver live images to a PC, an Internet phone, or a laptop. The cameras are tiny, but include many of the sophisticated features of full size digital CCTV cameras. CCTV customers are also seeking IP-based solutions with LAN/WAN delivery options despite some lags in the technology’s image quality and frame rate. “Make no mistake about it, the future is wireless,” says Thomas M. Wade, president of Samsung CCTV. “We’ll be pushing crime-related images to police cars in the future. Imagine an abduction or robbery in which the responding units are seeing the video and the suspects as they are rolling to the scene. It’s all possible and it is the general direction of the industry.”

There is also talk of linking CCTV cameras together to form a worldwide network to prevent terrorism, but this international surveillance system would cost billions of dollars and would require extensive international cooperation.
