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). We are looking at purchasing one to three 750 GB disks, at $240 each. Ideally, we would run two pairs of disks in RAID 0. |

=== Who will this benefit? === |
|||
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 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 one disk fails. 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. |

=== What will the machine be used for? === |
|||
The CSClub maintains our user data (/users) on our primary server, caffeine. When this system goes down, all of our other machines are rendered effectively unusable. Since this is our primary server, it also runs Kerberos, LDAP, Apache, MySQL, and PostgreSQL. This system is also the system most of users use. As such, caffeine is frequently upgraded, which increases the chances of it malfunctioning and going down. Caffeine has been down a number of times in the past. |

We have looked into different fallover systems, but we have not found a successful solution. We would like to create a dedicated disk server that would be used exclusively for holding /users and would not be used as a general-use machine. We are asking for the following hardware: |

New mirror server(s)
Background
- The CSClub is running a mirror for Debian and Ubuntu GNU/Linux distributions.
- Before this, there was no local Debian or Ubuntu mirror. We became a mirror in response to many CSClub members (and non-members) requesting this service.
- The machine that is running the mirror is under-powered and over-loaded for the task of mirroring, so we would like to replace the machine.
Who will this benefit?
- This will benefit members of the university interested in Linux and open-source software.
- We also plan to mirror additional archives as resources permit, so more people will likely benefit from this project.
What will the machine be used for?
- Mirroring Linux and other software distributions
What exactly are you asking for?
- 4U Antec case with 550W power supply ($285)
- Rails (2 x $45 = $90)
- Gigabyte GA-P35-DS3R motherboard ($155)
- Intel Core 2 Duo E6550 processor ($200)
- G.SKILL F2-6400CL5D-4GBPQ PC2-6400 4GB 2X2GB RAM (2 x $200 = $400; 8 GB total)
- Seagate Barracuda 7200.10 SATA2 160GB disk ($65; root disk)
- Seagate Barracuda 7200.10 SATA2 750GB disks (4 x $240 = $960; 3 TB total; mirror disks)
- Intel PRO/1000 PT Server Gigabit PCI Express network adapter ($90)
- SATA cables (5 x $4 = $20)
- 120mm fan ($11)
Total = $2276
We are looking at purchases two of these servers, but we would accept funding for only one.
How would you acknowledge MEF's contribution
- We would add a notice to the main mirror page indicating that hardware was provided by the Mathematics Endowment Fund, and provide a link to MEF's site.
- We would attach a MEF sticker to the front/side of the server(s).
Anticipated questions
- CSCF runs a mirror service (mirror.cs). Why can't people use this?
- Mirror.cs is not available to off-campus users.
- The CSClub mirror is already established as an official Ubuntu, Debian, and OpenOffice mirror.
- We would also like to mirror files/distributions that CSCF doesn't mirror.
