We purchased an HP 462834-B21 (SA P212/256 - no battery) and per HP, the controller is suppose to support 3GBs SATA. I have 4 Samsung 850 Pro 1TB SSDs connected to the controller via SFF SAS/SATA Drive CAGE 16 backplane ( DL170h server). Have enabled the cache battery ignore (ack on the dangers of doing so)... But the SSA is showing the Transfer Speed as 1.5 GBs? Additional IOMeter testings validates that the xfer speed is only at 1.5 Gbps and not 3 Gbps.
Did a lot of research and I see the P212 with a 1.5 GBs SATA and a 3 GBs SATA listing. Is there some specific need for this controller to opperate at 3 GBs SATA? or perhaps there are 2 different P212 ? I usually don't like quering the experts until I have done my due diliganece but having done so, not sure what I am missing... Before I go back that the controller is the problem, hopeing someone here can shed some light.
