We are having raid performance issues on our HP Proliant DL380 Gen9 server with the P440ar raid card PN 726736-B21. So i would like to install a 2nd raid card to move one of our SQL servers onto a new raid built with SSDs. I'm looking at ordering the HP P440/4GB FBWC 1 port SAS controller PN 726821-B21 with 6 of the HP 400gb 12G SAS Mainstream Endurance drives PN 741142-B21.
From what I've read both of these should work with 2 raid cards in the GEN9 server. The problem I'm having is I think I need to order some type of tray that the 2.5" drives actually sit in and that connect the drives to the server. So basically two questions?
Do I need to order cables or will the new card come with that?
Do I need to order a hard drive backplan kit? It looks like this could be the correct part? 719067-B21 or 768856-B21..
Am I missing anything else required to get this setup?
Thanks
