View source for Machine Specifications - Round 2

=== Machine specifications for second round purchase ===
Discussion on this page is public so please avoid any comments that would bring the department into disrepute.

====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?<br>
- Multi 10G NICs (2-port can be Gen.2, 4 port must be Gen.3 or x16)<br>
- Several 40G NICs (must be Gen.3, if 2-port needs to be x16)<br>
- Optical switch (e.g. Polatis, Glimmerglass, ideally 192x192...)<br>
- fibres and direct attach cables for the amount of NICs<br>

===Networking machines===
- Support full PCIe size cards<br>
- 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<br>
- Haswell CPU or higher<br>
- 2 sockets (but only few machines fully populated)
- >3GHz freq<br>
See evaluation report here: [https://docs.google.com/document/d/1UHC0FaylwvpGbeXcVh8s1axDQfmzSvejWTf_lRCAgzI/edit?usp=sharing link]

Additional requirements (to be tested before purchase):<br>
- Be able to drive 100G adapter cards (support bifurcation) <br>
- 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)<br>

==== Large memory machine ====
Single threaded computing

====Storage experiments====
Attached fast storage devices such as PCI card memory

====Storage machine====
Storage server(s) that are used for experimentations (i.e. not to store experimentation results, but for dev & test)

====Multi-core machines====
320 core machines<br>
"simple" multi-socket 8+ core machines

====GPU====
NL groups interested in this - will it fit in the above?
