Fragmentation - Hiding Your Head in the SAN

Friday, May 23rd, 2008

Okay, perhaps it’s a bit of a hokey metaphor, but there are apparently still people out there believe that because Storage Area Networks (SANs) utilize high-speed disk technology such as RAID that they don’t suffer the effects of file fragmentation.

A SAN is a high-speed special-purpose network (or subnetwork) that interconnects a number of data storage devices (usually hard drives) with data servers. They generally implement multiple physical disk drives in some form of fault tolerant disk striping (RAID), and do provide a great benefit to an enterprise: because stored data does not reside directly on any of a network’s servers, server power is utilized for business applications and network capacity is released to the end user.

Because the purpose of fault tolerant disk striping is to offer redundancy, as well as improved disk performance by splitting the I/O load, it is a common misconception that fragmentation does not have a negative impact. But moving in a bit for a closer look, it can be readily seen that file fragmentation does indeed impact a SAN.

Physical members in a SAN environment are not read or written to directly by an application. Even the Windows file system sees each set of striped drives as one single “logical” drive. As an application reads and writes to this virtual environment (creating new files, extending existing ones, as well as deleting others) the files become fragmented. Because of this fact, fragmentation on each logical drive will have a substantial negative performance effect.

When an I/O request is processed by the file system, there are a number of attributes that must be checked which cost valuable system time. If an application has to issue multiple “unnecessary” I/O requests, as in the case of fragmentation, not only is the processor kept busier than needed, but once the I/O request has been issued, the RAID hardware and software must process it and determine to which physical member the I/O request must be directed. Intelligent RAID caching at this layer can mitigate the negative impact of physical fragmentation to varying degrees-but it will not solve the overhead caused to the operating system with the logical fragmentation.

Because a SAN system is created, in part, as a high-speed storage solution, regular defragmentation is a must. But given today’s demanding applications, as well as the escalating number of sites that now operate 24X7, scheduled defragmentation cannot keep up. Fragmentation continues to occur in between scheduled runs, and in some cases isn’t impacting fragmentation at all. Additionally, the negative impact of defragmentation on performance has become intolerable in the constant access of a SAN environment.

The perfect defragmentation solution for SANs is one which will operate transparently, consistently, and without scheduling. It will only utilize available system resources, hence will have no negative performance impact. This basically means the drives within a SAN remain defragmented all the time, and maximum performance and reliability are assured.

So yes, SANs definitely do suffer from fragmentation. A fully automatic, transparent defragmentation solution is the best answer.

How Can Vista Out Run XP On A 512 MB Computer?

Wednesday, May 21st, 2008

Many people think that Vista will never out run XP on a 512 MB computer, I would have agreed to that if only the memory is lower, such as 256 MB. With some proper tuning, your Vista is absolutely faster than XP on a computer with the memory of 512 MB and above, just follow the 5 simple steps outline here.

Step #1 - Strip everything.

Bring your Vista on a diet plan, use vLite to generate a stripped down version of the original installer, you should lose as many things as possible, including driver and unwanted hardware support. If you can strip Vista until fit on one CD (600 MB or less), you are done!

Step #2 - Disable excessive services.

Do some study and disable all unwanted services, as many as possible . You should have stripped 1/3 of the services on the installer, now you have to disable another half and make Vista as tiny as possible.

Step #3 - Disable theme services and use classic menu.

You need classic interface to save your resources for application. Classical menu is very fast and smooth to use.

Step #4 - Use memory optimizer.

Vista will try to cache any application, you need memory optimizer to free the memory for application as much as possible. Memory optimizer can be obtained freely and easily, just types “memory optimizer” in any search engine, you should be able to download.

Step #5 - Use Process Tamer.

This tiny program will continuously monitor your programs, any program you are currently running, foreground or background, then set it to lower priority and free more resources for other application.

If you perform these 5 steps correctly, your Vista is definitely faster than XP on the same machine, try it today, and if you are not sure what to tune, get a copy of “Unleash Vista Power Advance Guide” before doing anything.

8 Surefire Ways to Get Your Students to Save Ink and Paper

Monday, May 19th, 2008

As a teacher, your job is not limited to teaching your students the rudiments of math, the foundations of science, the secrets of history, or the wonders of literature. It is also your job to teach your students to be responsible. Encourage your students to save on ink and paper by using these tips:

1. Require at least a couple of book sources for your assigned papers.

Requiring your students to use book sources will encourage them to actually read rather than scan or use other options like photocopying book pages using recycled paper for their sources instead of printing Internet pages.

2. Encourage the use of the draft setting for first drafts.

If you require your students to submit drafts of their papers, encourage them to use their printers’ draft setting. Since you will undoubtedly end up marking the pages in red, it’s a waste of good ink and paper. Using the draft setting will use little ink and thus, save a lot.

3. Teach students to proofread papers prior to printing.

Teach your students to check for grammar, spelling, and factual errors in their papers prior to printing. This will help them save ink and paper by preventing a lot of reprints due to errors in the text.

4. Extol the virtues of “Print Preview.”

Stress the importance of previewing pages before printing. This ensures that everything will look like they should on paper. Doing so will let them save ink and paper by preventing misprints.

5. Opt for online submissions whenever possible.

For short assignments, require your students to submit their papers online. Electronic submissions do not use ink and paper so students will be able to save these resources for more detailed presentations.

6. Stress the importance of turning off the printer properly.

Turning off printers instantly may cause the print heads to stop moving before they are in their proper positions. This can cause ink to dry up faster.

7. Require the use of black ink for text-only papers.

If an assignment does not require complicated charts or images, require your students to use only black ink. Alternatively, if picture is needed to stress a point, allow the use of gray-scaled images.

8. Make students understand that quality is better the quantity.

A longer paper does not guarantee a better grade compared to a shorter paper with more substance. Make your students understand this and they will submit shorter papers that are straightforward and more substantial. This also goes for printer inks. Tell students that it’s better to buy a more expensive ink cartridge that doesn’t smudge than a lot of cheaper cartridges that smudge or dry up without reason.

PPTP and HTTP Port Forwarding with Static NAT on a Cisco Router

Sunday, May 18th, 2008

Recently, a student at one of our seminars asked about port forwarding on a router. She wanted to allow PPTP clients to connect from the outside to a VPN server on the inside. In this article, I’ll explain how to do it along with a quick look at using static NAT to forward packets to a web server.

Port Forwarding on a Cisco Router

Sometimes we have internal resources that need to be Internet-accessible such as Web servers, mail servers, or VPN servers. Generally, I recommend isolating those resources in a DMZ to protect your office LAN from the bad guys, but regardless of how you choose to design it, the process involves forwarding desired packets from the router’s outside interface to an internal host. It’s really a fairly simple process. Here’s the configuration on a Cisco 2611 router:

interface Ethernet0/1
ip address 12.1.2.3 255.255.255.0
ip nat outside
!
interface Ethernet0/0
ip address 192.168.101.1 255.255.255.0
ip nat inside
!
ip nat inside source list 101 interface Ethernet0/1 overload
ip nat inside source static tcp 192.168.101.2 1723 interface Ethernet0/1 1723
!
access-list 101 permit ip any any

In the above configuration, Ethernet 0/1 is connected to the public Internet with a static address of 12.1.2.3 and Ethernet 0/0 is connected to the inside network with a static address of 192.168.101.1. NAT outside is configured on E0/1 and NAT inside is configured on E0/0. Access-list 101 works in conjunction with the “ip nat inside source list 101 interface Ethernet0/1 overload” statement to permit all inside hosts to use E0/1 to connect to the Internet sharing whatever IP address is assigned to interface Ethernet E0/1.

The “overload” statement implements PAT (Port Address Translation) which makes that possible. (PAT allows multiple internal hosts to share single address on an external interface by appending different port numbers to each connection.)

The statement “ip nat inside source static tcp 192.168.101.2 1723 interface Ethernet0/1 1723″ takes incoming port 1723 (PPTP) requests on Ethernet0/1 and forwards them to the VPN server located at 192.168.101.2.

You could do something similar with a Web server by changing port 1723 to port 80 or port 443. Here’s what that would look like:

interface Ethernet0/1
ip address 12.1.2.3 255.255.255.0
ip nat outside
!
interface Ethernet0/0
ip address 192.168.101.1 255.255.255.0
ip nat inside
!
ip nat inside source list 101 interface Ethernet0/1 overload
ip nat inside source static tcp 192.168.101.2 80 interface Ethernet0/1 80
!
access-list 101 permit ip any any

In this example, the web server is located at 192.168.101.2 and instead of forwarding PPTP (port 1723) traffic, we’re forwarding HTTP (port 80) traffic.

Obviously, you can configure your Cisco router in a similar manner to forward nearly any type of traffic from an outside interface to an internal host.

Why Have A Computer Network?

Thursday, May 15th, 2008

What exactly is a computer network? According to Wikipedia: “A computer network is two or more computers connected together using a telecommunication system for the purpose of communicating and sharing resources.” Arguably, network experts debate about this—they feel a computer network should be defined as a minimum of three or more computers connected together, not two.

Whether it’s a minimum of two or three computers to constitute a computer network, clearly the advantages outweigh the disadvantages. What are some of the advantages?

Let’s briefly cover the five advantages of computer networking. As Hutchinson & Sawyer brought out in Computers, Communications, & Information, the advantages of computer networks are: “sharing peripheral devices, sharing of programs and data, better communications, security of information, and access to databases.”

Sharing Peripheral Devices- Print sharing (where multiple users share the same printer) can cut operational costs. For example, large and expensive laser printers are used by multiple users within company networks. Providing a business has a network, large in-house printers can affordably be leased or purchased.

Sharing of Programs and Data- File sharing in the business environment is important, because it saves space, time, and paper. Digital files on a share drive are not only cost effective and convenient, but a company’s database is accessible to only authorized personnel and inaccessible to unauthorized personnel. Network-linked employees can share groupware and work together on shared projects. Purchasing network versions of software is yet another advantage of having a company network.

Better Communications- Schedules and task assignments can be easily shared and organized in a network. When emailing within a network, group settings and contact lists are easily kept up-to-date. Attaching scanned documents and emailing business communication is cheaper and easier than faxing information to another department at a different location.

Security of Information- When information is shared on a network and accidental data loss occurs, data recovery is much more likely to occur when working on a network. When shared information is stored on multiple computers and databases, it stands to reason that if a hard drive fails, others will have the shared information residing in another repository. Firewall appliances that are built for networks go far beyond what a consumer grade firewall can do.

Access to Databases- Typically, extensive databases (whether public or private) are shared on a network. Sophisticated databases have built-in parameters to protect the data from accidental overwrites or misuse by disgruntled employees.

As you can see, computer networks have many advantages and are understandably gaining popularity for small-medium sized businesses. It is no wonder why computer networks are notable for their cost-saving features and ease-of use for end-users worldwide. If you are concerned about your budget and need to set-up or improve your home or business computer network, call us at Genesis Global, Inc.: 1-800-908-9665.

HP Printer Cartridge Buying Tips

Wednesday, May 14th, 2008

HP has been a leader in printer industry for a long time. HP printers come in a wide selection, including the deskjet ink printers, laserjet printers, business inkjet printers, photo printers and designjet printers. Despite keen competition from other printer manufacturers, HP printers remain the most popular choice for home and business users.

The popularity of HP printers means that there is a huge aftermarket for HP printers. Indeed, consumers have many choices when they want to replace their HP printer cartridges. Here are some useful tips that can help you maximize your savings.

1) Remanufactured and compatible cartridges — HP has recently made a deal with Staples to remove all compatible HP cartridges from Staples retail stores. The move is considered as a victory for HP in the battle for printer aftermarket but this battle is far from over. Remanufactured and compatible cartridges are still readily available from major computer stores, office supply stores and hundreds of online ink / toner cartridge stores. These cartridges are in great demand because they offer a savings up to 30-50% compared to OEM cartridges.

2) Ink refill kits and ink recycling programs are another alternative for bargain hunters. Although it is a bit less convenient than buying a brand new cartridge, refilling ink cartridges is environmentally friendly and helps you save even more than compatible cartridges.

3) Combo pack — no matter whether you are purchasing compatible cartridges or OEM cartridges, you can usually get a discount buying the bulk pack or combo pack. If you are shopping from online stores, you can also enjoy free shipping when you buy several packs at the same time.

4) Online shopping — HP online store sells their OEM cartridges with free shipping. You can sign up for their MyPrint Rewards Club to get exclusive discount on ink and toner. Other online vendors also have OEM, remanufactured or compatible HP cartridges available at discount prices.

5) Coupon codes — many online vendors selling compatible cartridges provide coupon codes which give an additional 10-15% off on top of the original discount.

6) Warranty period — check the warranty period of your cartridges before purchase, especially if you are buying in bulk. A long warranty period means that you don’t need to open the packages and use the cartridges immediately but can return them at a later date if you are not satisfied with the quality.

7) Compare price and service — compare the price at different vendors, their shipping policy, warranty period and shopper’s satisfaction rating. Buying from reliable vendors can save you lot of money and hassles in the end.

Golf Technology - What’s New?

Tuesday, May 13th, 2008

Golf Technology is a wonderful thing. It has helped out heroes from yesterday like Jack Nicklaus and Tom Watson to stay competitive longer than they would have been able to otherwise. However, the good news is that the new golf technology has just not helped the professional players. It has also allowed amateurs many benefits to their game as well. What are some of the golf technology factors that currently affect the amateur’s game today? Here are a few suggestions:

Golf Technology - Through the research of many golf club manufacturing companies, including Titleist, the science of tracking a golf ball with a launch monitor was made available to more PGA Professionals and their club members. The launch monitor could follow the golf ball from impact, to the launch angle to the flight apex and finally to when and where it hits the ground including the ball’s roll out has greatly improved. Doppler Radar is now used to track all of the characteristics of ball flight. This now allows a player receiving a club fitting to swing multiple drivers to find the correct combination of length and loft just for them. Through using this technology, it has been discovered that most players hit longer shots with more loft on their drivers. Currently, some tour professionals are using drivers with 10.5 degrees of loft. Just a few short years ago, you would have been laughed at for having this much loft on your driver. It was thought that the less loft you needed on your driver the better player (or bigger ego) you had. As these players used the new technology and discovered they could hit it farther with more loft on their driver, again, their ego took over and the switch to more loft was on! At the beginning of this revolution, it go to the point where some golf club companies would even place the “preferred lower loft” on the bottom of the head when the head actually had more loft on it. They did this so sales would not slump as they would have if the “real loft” was placed on the driver.

Golf Technology - If you polled most amateurs on what their “bad shot” is on the golf course with their driver, what type of answer do you think you would get? After giving literally thousands of golf lessons, I can promise you that the mass majority of golfers fade or in most cases slice the golf ball. The manufactures know this and have introduced the golf technology of closing the face of the majority of the drivers to be sold to the mass public by one or two degrees. This tweaking of the clubhead design of the driver is considered by the manufactures a design technology. Obviously, the closing of the face would allow you to hit straighter drives but in theory they should be longer as well. As the clubface is not as open as it was with “your driver”, the closed driver head would have less loft on it as impact is made and would provide a longer drive. Hmmmm thought the manufacturers. If golfers will hit it straighter and farther, we just might sell a few of these

The Wireless Golf Coach is a website created by PGA Professionals to provide affordable online golf instruction. This is accomplished by offering unlimited online golf lessons through memberships at http://www.virtualgolfswing.com With an online connection with your computer, PDA or phone, you can literally take your golf lesson anywhere. In addition, enjoy the competitive pricing in the online golf shop.

Loan Officer Training - Here’s A Strategy For Loan Officers - Don’t Do Everything

Monday, May 12th, 2008

How many times have you heard ads on the radio or television, “I’m a Loan Officer that does everything; good credit, bad credit, FHA, 100% financing, bla-bla.”

If that an accurate statement? Sure it is. Does that set you apart from the average Loan Officer or Mortgage Broker? Nope, it doesn’t. Almost EVERY ad you hear/see say those similar words. Think about it, when you were NOT part of the mortgage business, did you pay attention to those ads? Probably not. Do you think the average borrower can tell one Mortgage Company from the next? Probably not. Get my point?

What I’m saying is get focused on one thing. If you want to concentrate on sub prime, go for it. If you want to focus on FHA, then do it. If the Option Arm is your gig, then learn it well (that happens to be mine). There is no right or wrong product, but stick with one and learn it well.

After you feel you have one (we’ll call it discipline) mattered, learn another until you have that down as well. Then go on. Brand yourself by really getting the “nitty gritty” of one product down, then go for another. Become the FHA specialist in your officer. Be the LO others turn to when they need info on the Option Arm. Do You get where I’m coming from?

If you try to be all things to everyone, you may eventually succeed in them all, but that’s going about it the hard way. If you’re a Loan Officer that works in an office with other LO’s, there will be a few that are specialists at something, learn to piggy back with them while you’re learning another product. You will be surprised how that kind of teamwork will pay off in the end.

And now I would like to invite you to get “Mortgage Info With An Attitude” with Free weekly answers about the mortgage business in the Mortgage Mailbag. As a Bonus, you’ll receive the Special Report “The 5 Biggest Myths about the Pay Option Arm and the Real Truth About Them”. You can access this free service and the bonus at http://www.MortgageMailbag.com
