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

- Stagger startups on PDU
- UPS: for just the head node and switch? This may depend on the voltage of the PDUs.
- Switch: 10Gb/s.
- 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. Do the locals have access to this disk space? Maybe not.
- iDRAC: Ask CIS what they recommend
- Memory: at least 32GB of RAM to help cache the OS image. 64GB would be even better.
- How many RAID arrays (OS, diskless images, data)?
- Storage
- OS RAID1+S (3 disks)
- OS: We have been making 40GB partitions for / for over a decade and that looks to still work with RHEL8.
- Swap: 0 or 8GB at most
- OS RAID1 with a spare (no swap)
- /export/home/
- <hostnmae>: free hog
- Images RAID6+S (nmpost-serv-1 is RAID1, cvpost isn't even RAID)
- nmpost-serv-1 has 2TB for OS images and is
- using1.2TB of it.
- Working data (local and nrao)? RAID6+S or RAID10+2S?
- OS RAID1+S (3 disks)
- Software RAID, ZFS, RAID card?
- 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?
