At Linaro we have one of those HPe Moonshot beasts. Basically it is chassis with some Ethernet switches built-in. Then you can plug cartridges with processors into it. There are some x86-64 ones and there are M400 ones with X-Gene cpu, 64GB ram and some SSD storage.
And there was delivery at Linaro office. With huge pile of M400 cartridges. Gema opened chassis and started to plug one after another until we got all 45 slots used (we had 15 cartridges before):
Turned out that one slot is dead so we have to live without c22n1 cartridge. But that still gives us 44 octa core systems. Each has 64GB ram, storage size varies (some have 480GB, some 120GB, some do not want to tell).
We are waiting for another chassis to fill it with rest of M400s ;D
There will be some work as we need to get them updated to be SBSA/SBBR compliant (U-Boot -> kernel is something I leave for some Company but it is not how Linaro expects) - we need to replace firmware setup.
Plans for use? Linaro Developer Cloud, OpenStack 3rdparty CI and probably several other targets.
