Lipstick on a pig
Some people will be fooled into thinking array-based SCM has a magical superpower. It does not. This is an attempt to mask that DELL (a kinda big server manufacturer) does not have server-side PMEM software. If you want the absolute lowest latencies, you need to leverage server-side PMEM.
Array-based SCM makes the last mile in a marathon faster. Server-side makes the whole marathon a sprint.
Dell's approach is half-assed as every vendor has (or will have) array-based SCM. Equallogic did something similar years ago.
