This was interesting …

We were asked for an “emergency” quote for a system for a grant. One of the components fit nicely into the ΔV paradigm, basically as a disk to disk backup of 2x the main storage size for this cluster. The 24TB ΔV came in under $15k. Made me happy.
Could have done the 36 TB ΔV, and I did consider it. It would have been overkill for this task.
And it would have cost much less than $20k.
