GPUs? 1U or 2U?
1Gb/s might be enough. 10Gb/s if similar price.
30 1U nodes or 15 2U nodes
A test unit at NRAO (a head and a couple of compute nodes)
PDU or two
UPS for just head node unless the site has UPS power
environmental monitoring
rackmount KVM (not remote) and patch cables
NVMe drives for nodes
Since we are making our own little OSG, should we try to leverage OSG for this or not? Or do we want to make each POD a pool and flock?
How do we handle the 50% workload?
