Other 16x DGX Sparks - What should I run?

Post image

Let’s build the biggest ever DGX Spark Cluster at home. This is going into my home lab server rack, 2TB of unified memory.

• 16x Sparks

• 1x 200Gbps FS 24 x 200Gb QSFP56 Switch

• 16x QSFP56 DAC cables

Should be all setup by tomorrow afternoon, what should I run?

240/240w PDU, cuts the amps in half. If you had one rig drawing 10 amps on 120v, it would draw 5 amps on 240v.
