I was going to do some photo editing today when I got home. Kids are running around outside collecting candy since it's Halloween. I turn on my computer to find that it doesn't start.
Time to call the Ghostbusters!
Happy Halloween Everyone!
Tomorrow I go buy a new power supply! lol
So the weekly advertisement came in today and I didn't bother to look till I was told Best Buy and Future Shop is advertising the Galaxy SII for $169 and $149 respectively with 3 year contract. So tempted!!! Anyway, the advertisements say prices valid between the 15th and the 21st of July. I'll drop by tomorrow after work to see if they in fact have it in stock (or if it's all sold out by then...haha).

While testing new HP G7 servers meant for database applications at work, the category of storage is an important one. Certain function such as online RAID expansion and migration allows one to reduce the initial cost and purchase storage as required.
I've been hearing and for the most part, experiencing what a few has described as HP Magic. Simply put, complicated things just work, we don't know how they get it to work so well, but it does. There are times where this is not true, and in testing of the Smart Array P410i on the DL360 G7 servers, I realized how unsafe it is to expand arrays on these and possibly other controllers.
HP ensures that a battery backup module is installed before allowing array expansion. This creates the idea that the expansion process may recover in the event of loss of power, hard shutdown, reboot, etc. This is not documented however, resulting in my curiosity to test how well it works.
Test 1 - Reboot
Test 1 Result
Update: Citrix has added a knowledge base entry now regarding this issue: http://support.citrix.com/article/CTX127395
Update: The just released Feature Pack 1 does not seem to fix this issue which is listed as a known issue (C-state problem).
It's been a long time since I've made a post about anything since I've been so busy. However, there's one update that many system admins would find very useful!
I first started down the path of virtualization over 3 years ago with opensource Xen server on various distributions (Opensuse, SLES, and Fedora) in an attempt to increase resource utilization. Many work places now use Citrix XenServer (previously owned by XenSource). I too have gone down this path for the ease of management. However, all is not well and there's something rotten in the world of Xen virtualization.
It seems that many are reporting Nehalem based servers encounter random lockups and network related issues. Here's my summary:
