I am glad to get this page back again

It's now 1:38am and I am so happy to get this page back. I did the upgrade to the lastest Drupal 5 but could not resist to attemp the upgrade to the latest Drupal 6. But guess what, it DID NOT work. Weired problems here and there and I gave up eventually. I will migrate to Drupal 6 instead next on another server which has more recent systems such as php 5. :-) . I know it's time to upgrade this web server now. But I am glad to get this page back again. Thanks to the precautious complete backup.

Cloud - Evolution or Revolution

There are so many buzz words out there for cloud computing and google type infrastructure etc. It's my first time yesterday I saw the real thing yesterday when I came across in one of the largest data center in Toronto.

EPEL trouble in automatic server deployment

"Extra Packages for Enterprise Linux (EPEL) is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages for Red Hat Enterprise (RHEL) and its compatible spinoffs such as CentOS or Scientific Linux. "

What's great about lifecast

Read the page at www.dandelife.com: "Dandelife is a place for you to record the events of your life, past and present, public and private. Have you photos and videos online in different places? No worries. Like you, your Dandelife is ultimate mash-up. Live well - we're listening!" I was looking for this kind of tool to put together with a community site I am maintaining, I hope this will work. Please let me know if you know any site like this. Thanks.

Working on OO based system administration

It's now possible to code your infrastructure configuration with some of the advanced tools. One step further on this subject is to do object oriented system administration. A new area with a lot of promise and benefit for both effieciency and security. Will post more for my progress.

What a day for commuters.

It was really messy today when I was driving along 404 southbound.

There were 5 accidents and traffic was so jammed up. I would prefer to work from home if I can choose. Thanks.

Replacing Windows desktop with Linux desktop

To be honest, I am not  a desktop guy and that's why I stick with Windows desktop for a very long time. I always think Linux lacks support for some of my favorite hobby applications. :-)  You know I am a server guy so I don't really need that much from desktop for my work. But this time I decide to make some serious change as once again my WinXP totally screwed up on my old home pc.

Create 50 SAN Volumes in 1 minute

I was asked to setup a mixed SAN infrastructure with both fiber and iSCSI SAN products. One of the requirement is to create over 50 of the volumes. It will be tedious and time consuming if going through the GUI one click at a time so I decided to give it a try using CLI and some ruby code to help.

50.times { |x|
    puts "volume create Tables#{x+1} 100G pool bigsan"
    puts "volume select Tables#{x+1} access create ipaddress 10.1.1.*"
}

Network Recommendation for iSCSI implementation

  1. Switched Gigabit Ethernet network : Connect arrays and hosts to a switched network and ensure that all network connections between hosts and arrays are Gigabit Ethernet. An array can operate at 10 and 100 Mbits, but performance will be significantly degraded.
