SCv2020 SSD Write Latency

Hi All

We have recently added an SCv2020, with 16 x 1.92TB SSDs into our existing EQL environment. An VM I move, while it sees much lower read latency, is seeing higher write latency than before.

Its marginal I grant you, however the unit is only doing about 400 IOPS in total, with maybe 6/7 VMs on there. I have tried with and without the write cache, after reading a few threads on here, but it still seems very spiky, even under low IO.

Has anyone seen anything similar?
