Fall 2007
New server for mirroring
The CSClub is running a mirror for Debian and Ubuntu GNU/Linux distributions. We would also like to archive the raw AVI's of our talks (~ 20 GB each). The machine that is mirroring our talks (natural-flavours) is underpowered and we would like to upgrade it.
We would like to purchase the following:
- Two or three 750 GB SATA disks [also using existing SATA and IDE disk] ($240 each)
- 2 GB of RAM [also using existing 2 GB of RAM] ($90)
- Gigabyte GA-P35-DS3L Motherboard ($120)
- Intel E6550 ($210)
- SATA RAID controller ($400)
- Corsair VX550W 550W Power supply ($95)
- SATA cables ($10)
We would run the set of disks in RAID 5, which would provide 1.5 TB (if we purchase two disks) or 2.25 TB (if we purchase three disks), of disk space. RAID 5 provides reliability in the case of single disk failure, through the use of parity bits across disks.
We are willing to accept funding for two disks, but we would prefer funding for three disks.
We would use the old parts to upgrade one of our office terminals.
Total: $1405 - $1645
Disks for taurine
The CSClub received funding for taurine from MEF, with one of its purposes being to run virtual machines. We currently have two 72 GB disks in RAID 0 (striped) mode, which means the disks are joined to form one logical 144 GB disk providing no redundancy. We would like to request funding for two 146 GB disks (model number 431958-B21). We would then run the two sets of disks in RAID 1, which provides redundancy in the event of single disk failure. The HP public sector pricing for a single disk is $512. However, local vendor pricing is typically a few percentage points lower. The cheapest online retailer is $468 per disk. In total, both disks would be at most $936. The disks are more expensive than commodity desktop disks, as they are low-profile (2.5 inch) and SAS (Serial-Attached-SCSI); these are the only type of disks that will work in this machine.
Total: $936
KVM-over-IP system
The CSClub has a number of servers in the MC 3015 machine room. MathSoc and other clubs also have a few systems in MC 3015 as well. If system in the machine room goes down after-hours (e.g. the evening or weekends) we are unable to physically access these systems to perform maintenance. Having a KVM-over-IP system would let us diagnose and reboot systems. It would also reduce the number of times we need to bother the operator in MC 3015.
