Where There’s a Will, There’s a Way

For a variety of reasons the main server room for the firm I support is located in an electrical “closet” in the headquarters building’s basement. There is no AC, only a powerful blower to introduce fresh air to the small space. This has meant that the servers have always been sucking in very warm air, frequently very dusty, and sometimes literally full of small flying bugs.

To make things a little stranger there is an actual properly built server room also in the basement. However, it is a very large room that was obviously set up for the oil company that used to occupy the building in the 1990′s. Currently this “server room” is used for filing storage for client discovery and up until a few months ago the room was quite full of file boxes. I gave my IT Admin the job of figuring out how we could fit in a 4-post server rack inside this room without losing any storage space for the files. Seems difficult since the room was full but when I looked at the way things were in there it seemed like there was a lot of wasted space.

iCal + iCal Server on Mac Xserve – It’s Alive!

Back in late November I tried to get iCal Server running on some older hardware and this is what happened…

I ran iCal Server + iCal in a test environment on a older Xserve–Dual G4 1GHz 2GB RAM Mac OS X Server 10.5.5–in this test environment with only a couple of test users and I noticed a significant increase in CPU activity due to iCal but it seemed that it wasn’t something the server couldn’t handle. A month later when I rolled out the service to 60+ users the server was brought to its knees. It ramped up to 100% CPU usage as more users logged in and by about 11AM that business day it ceased to be functional. Anyone trying to connect timed out before they received updates.

I have not been able to track down any specifics as far as something I can “fix” to prevent this problem as my iCal Server install is Apple default and other than running the CPU load at 100% there was not a single error reported/logged. I’m going to use brute force to work around the issue but I would like to find a better approach.

I am going to try to roll out this service again but hosted on a brand new Xserve 3.0GHz Quad-Core Intel Xeon 16GB RAM (I’m lucky in that I work for a bunch of lawyers).

Now two months later I think I have finally got it working…
