Storage for experimental data
Some fibre-channel/NFS provision Looking at 1PB storage in total. Looking for a system where this could at least be doubled if necessary. Want NFS access to the files ideally.
Networking requirements
What networking kit is needed here?
- Multi 10G NICs (2-port can be Gen.2, 4 port must be Gen.3 or x16)
- Several 40G NICs (must be Gen.3, if 2-port needs to be x16)
- Optical switch (e.g. Polatis, Glimmerglass, ideally 192x192...)
- fibres and direct attach cables for the amount of NICs
Networking machines
- Support full PCIe size cards
- PCIe Gen. 3, multiple slots of x16 or x8 - At least 2 slots which are 2-slot-wide and 2 slots that are 1-slot-wide
- Haswell CPU or higher
- 2 sockets (but only few machines fully populated)
- >3GHz freq
See evaluation report here: link
Additional requirements (to be tested before purchase):
- Be able to drive 100G adapter cards (support bifurcation)
- Be able to drive 4 x 40G (2 x 2 x 40G or 4 x 1 x 40G), to 2 processing sockets (to be tested using two 80G Solarflare cards)
