Sorry, I was thinking the R620. With the M620, the H710 won't support using the SATA backplane. The only backplane configuration supported by the H710 is the SAS backplane (part # 319-1700) I apologize for the confusion on my part, and hope this helps.
I've got a few PowerEdge M620 that were supplied with a SD cards only. I've been using them to run ESXi for the last few years. I've now been asked to transfer everything over to Hyper-V. After contacting Dell they sent out SAS drives and a PERC H710. It turns out that the back plain was for SATA drives, these have been returned and SATA drives sent out. The on board S110 can pick the drives up but the PERC H710 can't see the drives at all. Does anyone know what I'm missing?
