I had the same issue with SATA SSD (PowerEdge R720xd, PERC H710 Mini, Intel SSDSC2BB300G4T Revision D201DL13, Windows Server 2016 tech preview), and this worked for me: Download Intel SSD Data Center Tool. It showed no results until I was careful to run as administrator and enable the LSI adapter. isdct set -system EnableLSIAdapter = trueisdct show -intelssdisdct set -intelssd xx physpeed=6(where xx is the drive ID as reported by isdct) I actually have a mix of Dell and non-Dell S3500 SSDs, and I found this solution after noticing the non-Dell ones were operating at a higher speed than the Dells. The Intel tool also provides a way to check the health of the non-Dell SSDs and to update their firmware. This post set me on the path.
Hello. PowerEdge R720 here * all latest firmware updated and I MEAN ALL. * all CERTIFIED DELL BRANDED drives Twin Quad Core E5-2609 56GB RAM 6 x Dell branded 300GB SAS 15k: capable 6gbps, negotiated 6gbps Seagate ST3300657SS revision ES66 2 x Dell branded Intel SSD DS S3500 480GB: capable 6gbps, negotiated 3gbps: INTEL SSDSC2BB480G4T revision D201DL13 My problem is that the SSD are NOT negotiating at 6gbps. I have updated the drives to the latest 6gbps firmware. I have checked that force 3gbps transfer for SATA is not selected. I removed the power and press the off button for 10 sec, I swapped the drives trays, what else? THANKS IN ADVANCE. Randolph.
