Datrium claims its split-provisioning DVX array is 'tomorrow calling'

Thanks, Chris. Glad you liked my quote. On the question of what happens if all DVX Compute Nodes go down at once, it's simple. Datrium Compute Nodes are stateless; they use flash locally for speed, but persistence is off-host. If all hosts go down and then one comes back up, the restarted host just starts using data, and no rebuild is required. This is a contrast to HCI, where if a server goes down, rebuilds are required, and multiple servers down can stop data access for the others.

@buzzki11, we call it a Compute Node if you buy it from Datrium because it includes our software for data services; none of that runs in the Data Node. Even erasure coding and rebuilds for the Data Node drives are performed by hosts running DVX software. We just use terms this way to try to be clear. If DVX is deployed with third party servers, we'd upload that software.
