- 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.
- Storage mdRAID, ZFS, RAID card?
- OS/OSimages, RAID1+1 (3 disks), about 1TB
- 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
- /export/home/<hostnmae>: services and diskless_images
- Working data/software (local and nrao), RAID6+1 (9 disks), about 72TB
- An SE imaging input data size is about 10GB per job
- We need maybe 20TB+ of total space or more so maybe 60TB/2
- Carve into two partitions (NRAO data and NRAO software, Local data and Local software) each partition has data and software directories.
- OS/OSimages, RAID1+1 (3 disks), about 1TB
- Networking: May need more than one port. One for internal networking to nodes and one for external Internet access.
- 30 1U nodes or 15 2U nodes or mix? NVMe drives for nodes. Swap drive?
- NVMe for scratch and swap
- 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?
