Hardware
- GPUs? Do we get 1U nodes with room for 1 or 2 Tesla T4 GPUs or 2U nodes with room for 1 or 2 regular GPU?
- 1Gb/s might be enough. 10Gb/s if price is good.
- 30 1U nodes or 15 2U nodes or mix?
- head node with lots of disk
- test head node at NRAO (either CV or NM)
- one PDU or two PDUs? What plug? What voltage? This may very across sites.
- UPS for just the head node and switch?
- environmental monitoring Could the PDU do this?
- rackmount KVM (not remote) and patch cables
- NVMe drives for nodes
- Cabinet Rack Cabinet Rack: Doors front and rear locking with mesh. Width: 19". Height: 42U is most common. Depth: 42" or 48"? Rack must support at least 2,000 lbs static load
