@RobH: please request quotes for 2x 4 servers as outlined above. Thanks!

To consolidate infos.

Ok, seems some confusion has been clarified. The maps team immediate need to launch maps for all wiki projects is 16 varnish servers (4 per cluster), and 8 backend servers (4 in two of the clusters). The backend machines need 1+ TB SSD harddrives. The backend machines we have been using have 96GB 12 cores, and this has been working out very well. @mark, please comment regarding the state of Discovery hardware funds for this fiscal year, and if we need to allocate anything for the next year. Other than the above hardware requirements, I think the Maps project should have enough hardware to satisfy our needs for the next year. Thanks!

Please only look at the backend side for the above comment. I will open another request for the varnish servers.

Summary of IRC discussion:

• the current H/W for maps is not uniform. We have better specs on map-test2003 / 2004 than on 2001 / 2002. The better spec should be used as baseline
• that spec is 12 cores, 96GB RAM, 1+ TB SSD
• the SSD of the current maps cluster *could* be reused in new servers
• current servers are single disk RAID 0
• we should move to RAID 1 (under discussion, we do not seem to have consensus at the moment)

This is actually slightly of, 2001 & 2003 share specs, 2002 & 2004 share spacs.

I'll get the quotes for the single CPU with 12 cores and 96GB of memory. Please note that since we don't know the full load details, we aren't certain if the systems need more memory per core at this time. At 96GB, the current ratio os 8GB per core.

I'll get quotes for this,will link into a procurement task, which will include pricing from both Dell and HP. All pricing discussion will have to take place on the linked task T131864.
