== Disks for natural-flavours ==
== New mirror server(s) ==


=== Background ===
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 currently have a single 750 GB disks; we are looking at purchasing two or three additional 750 GB disks, at $240 each. We would then run the set of disks in RAID 4, which would provide 1.5 TB (if we purchase two disks) or 2.25 TB (if we purchase three disks), of disk space. RAID 4 provides reliability in the case of single disk failure, through the use of a dedicated parity disk. We are willing to accept funding for two disks, but we would prefer funding for three disks.


* The CSClub is running a mirror for Debian and Ubuntu GNU/Linux distributions.
== Disks for taurine ==
* 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? ===
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.


* This will benefit members of the university interested in Linux and open-source software.
== Dedicated disk server ==
* 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? ===
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.


* Mirroring Linux and other software distributions
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:


=== What exactly are you asking for? ===
* Motherboard: "Asus M2A-VM Socket AM2 AMD690G + ATI SB600 Chipset Dual Channel DDR2 800/667/533 Integrated ATI X1250 Graphics Micro ATX" - $79
* Processor: "AMD Athlon 64 X2 4200+ (65W) Dual-Core Socket AM2, 2.2GHz, 512KB x2 L2 Cache, 2000MHz HT, 90nm (ADO4200CUBOX)" - $98
* RAM: "Mushkin SP2-6400 DDR2-800 2x1GB CS 5-5-5-18 1.8V (996529)" - $103
* Case/PSU: "Antec NSK4480 New Solution ATX Mini Tower Case 3X5.25 2X3.5 3X3.5INT 380W ATX12V V2.0 Silver Black" - $89


* 4U Antec case with 550W power supply ($285)
We would move the 2 SATA disks from caffeine (400 GB each) and a 40 GB IDE disk from caramel-colour into the new disk server. The total amount we are requesting is $369.
* 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
== KVM-over-IP system ==


We are looking at purchases two of these servers, but we would accept funding for only one.
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.

=== 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.

  • 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.
