Number of systems: 1
Service: stat*
Networking Requirements: internal IP, in Analytics VLAN
Processor Requirements: 16+cores
Memory: 64G
Disks: 4 x 3+TB software RAID 5
Partitioning Scheme: 30G /, 100G /tmp, rest of space for /srv (I plan on putting /home in the /srv partition (via symlink?))
Other Requirements: GPU: See T148843
This ticket tracks replacement of the OOW stat1002.
GPU
In T148843, researchers asked for access to a box with a powerful GPU in the Analytics cluster. We explored the option of installing a GPU in an existent box, but decided to wait until we replaced stat1002 and stat1003, so that we could order a chassis that would fit the GPU they want.
@Halfak and @DarTar, please work with @RobH to select the GPU you want, and to find a chassis that will fit it.
Disks
stat1002 currently has an 10TB /dev/sda. I'm not sure of the exact layout here (hardware raid?), but I think we don't actually need so much space anymore. Previously, stat1002 was the main log storage host. This functionality has mostly been moved to Hadoop. Folks now use stat1002 (and stat1003) compute resources for number crunching on local files, but they shouldn't be doing crunching on huge historical log data there anymore. We still need a large working space, but we don't need 10TB. Let's provision this in such a way that we have the most space we can, but with a fault tolerance of at least one disk. RAID 5?
4 x 3+TB disks in software RAID 5 should be fine (this is the layout we have in stat1003 now).
