Optiplex machines
The slackware version seems slow, even the terminal.
The ubuntu live cd takes a while to boot, but seems more responsive.
Update: Need to change SATA operation to normal mode from combination to allow Ubuntu to see the hard drive.

Wishlist
Uninteruptable power supply for the servers.
Phone for the real time lab.
Hard drives for backup space.

Server Notes
unix: Dell Poweredge 1850, Xeon processor, 1GB ram, ~15 GB hard drive, Megaraid. Running slackware with a 2.4 kernel. Missing many common utilities.
file: Dell Poweredge 2800, Xeon processor, 1GB ram, ~130 GB hard drive, Megaraid. Running slackware with a 2.6 kernel.
Concern: Slackware has weak package management.
Possible solution: Suse Enterprise Linux is supported for these machines. Unclear if openSuse can handle it. Other linux solutions have mixed reports about getting the raid working.
Question: How useful is the hardware raid?

Server Migration
Started Tuesday morning, Shawn, Symen, and Joe showed up.
Moved the case from Hawkins 53B to 36A, need to decide what to do with former (unknown servers) that were in the case.
Moved servers to new case, servers are too deep for the case. Removed back door of case to allow them to fit there. Probably need to find a longer term solution.
The machines are somewhat loud, so it is better not to have them in the main teaching lab.
Contacted networking support to turn on the ports.
Networking issues were resolved Wednesday morning.
Some minor nfs problem. The server seemed confused about who it was exporting to. Needs further investigation.

Ubuntu Installation
In the redcay lab tried to install ubuntu on E24 and E23. They both hung on hdc problems.
Update 1: Tried booting laptop and home machine using the disk and they worked fine.
Update 2: Talked to Jim Owens, he indicated that he had experienced problems on machines that had less than 256 MB of memory.
