Overview

We assume the site will be buying 15 Compute GPU Nodes.  Things like the power and ethernet cables are based on this assumption.

Head Node

The test node purchased for NRAO was a Compute GPU Node, common and this is what we are recommending for all the other clusters.

Compute GPU Node, common

(760WDell recommends 208V to get the full capacity of the Power Supply)

I unknowingly mistakenly bought power supplies for the NRAO test system with C20 recepticals (2400W) instead of c14 recepticals .(1400W).

Strip Options

We require 208 Volt power.  Two common plugs in the United States for 208V are NEMA L21-30P for 30Amp power and IEC60309 60A 3P+PE for 60Amp power.  Each site will need to choose one of these options.

Cables

Power Cable Options

Some data centers have overhead power (Top power) and some have underfloor power (Bottom power).  Each site will need to choose one of these two options.

Top power

  • Nodes + spare
    • 3-foot, C13/C14, Y-splitter (wide), qty 17
  • Switch + spare
    • 6-foot, C15/C14, qty 2 NOTE these are C15 not C13
  • KVM + spare
    • 2-foot, C13/C14, qty 2

Bottom power

  • Nodes + spare
    • 4-foot, C13/C14, Y-splitter (wide), qty 17
  • Switch + spare
    • 4-foot, C15/C14, qty 2 NOTE these are C15 not C13
  • KVM + spare
    • 3-foot, C13/C14, qty 2

Ethernet Cables

  • 10-foot, Cat-6a, qty 7
  • 7-foot, Cat-6a, qty 8
  • 5-foot, Cat-6a, qty 4

Blank Panels

2U Rack Drawer

UPS (Optional)

just for switch and head node

  • APC Smart-UPS X SMX2200R2HVNC 208V, $3,125
  • 3-meter, Cat-6a, RF-45 ethernet cables
  • various power cords, Y-splitter, wide enough for R750

Software

Since we are planning to use all free and open-source software (RockyLinux and HTCondor) there isn't a need for software costs.
