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
PDU: one PDU or two PDUs? What plug? What voltage? This may very across sites. What if the site has two power sources?

UPS: for just the head node and switch? This may depend on the voltage of the PDUs.
Switch: 1Gb/s might be enough. 10Gb/s if price is good. Test Switch at NRAO?
Environmental Monitoring: Could the PDU do this?
KVM: rackmount, not remote, and patch cables
Ethernet cables:
Power cables: single or Y calbes depending on number of PDUs and two power sources.
Head Node: lots of disk. Test head node at NRAO (either CV or NM)
30 1U nodes or 15 2U nodes or mix? NVMe drives for nodes. Swap drive?
GPUs: Do we get 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?

Keep each rack as similar to the other racks as possible.

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?

Should we try to buy as much as we can from one vendor like Dell to simplify things?
