XenServer Hardware Updates? Here's Your Answer!
NOTICE: IF THESE STEPS ARE PERFORMED INCORRECTLY OR WITHOUT TESTING IT IS POSSIBLE FOR YOU TO WIPE OUT YOUR XENSERVER DATA LOSING ALL STORAGE REPOSITORIES. TAKE GREAT CARE WHEN FOLLOWING THESE INSTRCUTIONS. Strickland Networks is not responsible for someone erasing their virtual disks by mistake.
Now that that is over, let the fun begin!
I was updating a 6 server XenServer Farm yesterday and came across a memory error. It started out as a hardware (HW) error and then turned into a BIOS problem. The Dell Engineer then began to search for the updates that I would need for my Server. The Dell representative was very helpful and began putting together a list of updates that I would need... I began to ponder the multitude of different servers that I had to update after I finished with these six. I also know that I have a Windows update DVD that will update all the Dell hardware on my Windows Server plus the drivers.
I asked the question to the Dell Tech and he replied that yes there was a solution. You need these two DVDs:
DVD 1 (System Management Tools and Build - DVD):
ftp://ftp.dell.com/secure/sysman/OM_6.3.0_SMTD_A00.iso.001
ftp://ftp.dell.com/secure/sysman/OM_6.3.0_SMTD_A00.iso.002
DVD 2 (BIOS and Firmware Images - Dual Layer DVD)
ftp://ftp.us.dell.com/sysman/om631_suu_a00.iso.001
ftp://ftp.us.dell.com/sysman/om631_suu_a00.iso.002
ftp://ftp.us.dell.com/sysman/om631_suu_a00.iso.003
ftp://ftp.us.dell.com/sysman/om631_suu_a00.iso.004

Proceed down to see the process.
It should be noted that this same process can be run on any Linux Server. It is not recommended on Windows Servers due to possible driver incompatibilities.

Moving to the cloud? How to ensure that information is reachable.
Biggest problem with the great cloud migration: getting there.
I am a HUGE fan of moving what makes sense for your business to the cloud and letting others worry about the maintenance and upkeep of equipment and software. But here's the catch, what happens to the average company when their Internet goes down? You email, you backups, your accounting software, and everything else that you have trusted to be moved to the cloud is now inaccessible. Do you send all your employees home and have them work there? Can you trust your employees to not just goof of the rest of the day?
How to minimize your risks:
Get redundant Internet! Don't be lazy about it and buy two T1 lines from the same vendor, because those will most likely both go down at the same time. Buy a backup DSL or cable line into your office. It will be worth the minimal monthly investment.
Buy a router / firewall that can handle it. We love SonicWALL products at Strickland Networks. Most of the models automatically handle dual Internet connections. Meaning if the primary is unavailable, outbound traffic is automatically sent through the second connection. But it gets better, many models you can add a high availability unit as well. This gives you 2 SonicWALL firewalls working in tandem to prevent downtime in the event of a hardware failure as well. Now you could lose 1 firewall and 1 internet connection before becoming unproductive.

Why are you still using tape to handle backups, disaster recovery, and business continuity?
Quick poll, how many of you still own a VCR and still use it regular? Most of you are using DVD / Blu-Ray or streaming it over the Internet. So why do you hold your data backups in the prisons of tape?
There are a great deal of solutions out there that are disk based and store your data in a secure spot in the "cloud." But why settle for just backup when anyone can provide that? How much better would a total solution that covered recent backups, disaster recovery and business continuity be for your company? Our solution at Strickland Networks is called TotalProtect because it keeps you protected in all of these three categories.
Backups
An initial backup is done and then continuous incrementals follow behind. The first destination of backups is to local storage at your site. That can be a Strickland Networks recommended NAS device or your own storage. The next destination for your data is off to our data center. There, the base image plus 1 month of your most recent data is kept.
Disaster Recovery
Let's assume worse case scenario, your entire office is destroyed by an act of nature. Strickland Networks can virtualize your most recent backup sent to our data center and help you make changes to allow you and your company to keep working remotely until a new physical location can be found for your office and new equipment purchased. Then we'll help transition back to the new hardware - all with minimal downtime.
Business Continuity
We've all heard the horror stories. Or maybe you've experienced it first hand. Your Server RAID has failed beyond repair, memory fails and the parts are out of stock, CPU's over heating ... whatever the issue, with TotalProtect you have the ability to turn your backups into a running virtual server or do a bare metal restore to new, dissimilar hardware. Your down time is now hours, not days.

Citrix High Availabilty
Some people will try to tell you that the only enterprise class virtualization out there is VM Ware, but I am here to tell you that Citrix is a contender. Not only is it a contender but it is growing in features and in acceptance. Citrix XenServer is actually the World's largest Internet Facing Virtualization environment, Amazon Elastic Compute Cloud (EC2). Because the foundation of XenServer is built on the open source Xen, there is lots of opportunity for developers to to build upon the feautres and functionality of the product. One such features is Everun by Marathon Technologies. The product will allow you to even unplug the server that your primary node is running on and the transfer to the secondary server is so seemless that if you were running XenApp on the server your end users would never even know that they swicthed to a different server.

Pesky Passwords
We've all heard the lectures about password security 100 times. We know the basics like "don't use real words," "no names of your family members," and "the most common password is the word "god." We've heard these things before and I think most of us have a false sense of security about our how secure our lives are.
These days, password cracking tools are freely available on the internet. "Hackers" with almost no skills download powerful tools that rapidly attempt to guess a password using combinations of every word in the dictionary and every name. Personal computers are becoming more and more powerful meaning that the time it takes to attempt these brute force password attempts becomes shorter and shorter. Also, new password cracking algorithms such as rainbow tables are becoming accessible, even to people that don't know how to use them.
On top of that, most people use the same password for everything. Their personal email accounts, their banks, their retirement accounts, their facebook etc. If not exactly the same, then some variation of the same. If a hacker guesses your password for one account, what kind of access to destroy your life do they have?
My final argument in favor of paranoia is this: Let's assume bank websites are secure. Those institutions put a premium on defending their customers from hacking attempts or internet vulnerabilities, so let's just assume those places are hack-proof. Addditionally, let's assume those sites are the one place where we keep a ridiculously long, very secure password that is different from every other website we use. Are we safe in this scenario? If I were a hacker, I would avoid bank sites assuming they're too hard. Instead, I would go after an email site. I would assume people keep less secure passwords for their email and therefore they are easier to get into.
What kind of information would a hacker have access to if he could gain full access to my email account. There's not really anything sensitive in my email account by itself. What I'm concerned about is how many other secure websites are tied to my email account. For instance, could a hacker go to my bank website and click the "I forgot my password" link and have my bank send a new password to my now compromised email account? What about my 401k website or my investment account. The possibilites are enough to keep me up at night.
So, what can we do?
First, follow good password behaviors.

Keep a separate, secure password for each
website.
I know how daunting this is, but there are tools to make it easier. Keepass is a free, open-source password database that is a highly encrypted place to store passwords. It will even auto-generate passwords that are as complicated as you want them to be. You only have to remember one password to open your entire database of passwords. It has the ability to copy and paste passwords so you don't have to type them and you can store the url's for important websites right in the app. There are versions of keepass that you can keep on a usb thumb drive or even on your phone. Another tool to make a secure life easier is Roboform - it has the same master password concept as keepass but will auto fill in website passwords once logged in.
- Don't use real words in your passwords
A trick to make this easier to live with is to substitute symbols or numbers for letters. For instance, if you want your password to be the phrase "world wide web," subtitute the lettering for something similar to "W0rldw1dew3b!" It's easy to remember and won't be found in any dictionary. Remember to use a mixture of lowercase and capital letters as well.
You can also use passwords based on phrases that are important to you. The phrase "The Lord is my shepherd, I shall not want" would become something like "tLimsIsnw."
Patterns on the keyboard are equally efficient. For instance, start on the bottom row with the letter "z" and click through to the "m" and then do the same patter in reverse on the top row of keys. Easy to remember, difficult to crack.
- Change your passswords periodically
I recommend changing passwords frequently, at least every 90 days. As personal computers get faster and faster, this can help keep you ahead of any password cracking attempts. The longer your password is, the longer it takes to crack.
- Keep your passswords at least 8 characters long
Hopefully, a good password policy will keep you out of heartache. A little extra precaution goes a long way in this always connected world we live in. -
Keep a separate, secure password for each
website.

AstraSync and Blackberry: Could it get any better?
Most all of my clients have either a BlackBerry or an iPhone. And almost all of them use Microsoft Exchange. This is not going to be a compare and contrast of who is better: the BlackBerry or the iPhone. Of couse the iPhone has ActiveSync integrated into the OS if you have the Enterprise Data Plan from your Wireless Provider. But now there is an equalizer, AstraSync enters the picture. AstraSync allows for you to synchronize your BlackBerry with your Exchange server without having to Install BlackBerry Enterprise Server or its free counterpart. AstraSync is like ActiveSync for the BlackBerry. It allows you to get and recieve Exchange Email, it updates your calendar and your contacts, you can flag messages and add attatchments. Pretty slick if you ask me. Also, what I hear is that you do not have to upgrade your phone to the Enterprise Data Plan to be able to use it. You can just get an unlimited data plan with your provider and away you go. The software costs $49 per year and is well worth it when you look at your savings from not having to have an Enterprise Data Plan. They also offer a free trial so that you can get your feet wet with to see if you really want it. Just use the link below to give it a try.

iPad, kindle, or nook... the choice is really hard. Help me decide which e-book reader to get.
I WANT an e-book reader and I must have one! I am tired of all the books I buy and having to keep up with them. I have broke down my thoughts and would love any comments to help me finally decide.
Kindle
The kindle with its low price has me wanting to go that direction more than any other. I know what type of books I like to read and amazon book store has most of the titles available for the Kindle. The e-ink and battery life of the new generation is very attractive. The big downside, I don't get all the cool features of the iPad. Apps, web surfing and so on.
Nook
In my opinion, I feel like this is a very similar product to the Kindle. Barnes and Nobles saw the success of the Kindle, tweaked and added some features and called in Nook. To me, there just does not seem to be enough originality to make me want to chose one over the other. Additionally, when I searched the BN site for books I like to read, less were available for the nook than the Kindle. I welcome someone to prove me wrong on this one and bring up some points I have missed.
iPad
Total awesomeness. I want it! But wait, reports I have read say two things bad. 1. it's not that great of a platform to read books on. 2. because of the light it emits, the iPad is more like watching TV than reading a book. Meaning that my sure fire way of getting sleepy, reading, now is going to keep me awake. Apple's selection doesn't seem to be that great right now (at least for the books I like to read). But it is Apple, that will change. I can't remember that last time I bought music anywhere but iTunes. We all know Steve Jobs wish is for the same thing to happen with books and media in general. We are now saying, "what's a CD?", but Steve Jobs wants us saying "What's a book" or "What's a Magazine".
Wrapping it up
What's makes this the hardest for me to decide is that I am cheap. I want to be a cool kid and have an iPad. But it's the most expensive option. My other issue in general is that a recent report shows that people read much slower on the "ebooks" than real paper.
