I've got an MD1220 in split backplane mode connected to two servers each with an H800. I had 8 Dell VDPRV S3500 SSDs in it, but in split mode only four drives are seen. I remembered with an MD1000 with SATA drives I have to have interposers, so tried some SAS drives I have, and that worked.
The question is, then, do I need an interposer for this and if so can someone suggest one?
