As you already know, HP will not claim any compatibility information since it is not an enterprise component and they do not have it listed as an option on any server model.
What I do know is that was a bug in the iLO software of overheating storage due to the fact that many SSDs do not have a temperature sensor. I believe this issue was resolved and other people are running other Intel SSDs on Proliant servers.
I just bought an Intel SSD 520 (SSDSC2CW180A2K5) for testing in a HP Proliant DL360 G7 with Smart array 410i controller.
The box contains the SSD disk and a 'SATA 6.0 signal cable'; but i can't see any connector in my Proliant server to connect this cable :-(
Anyone would know if I need another cable for this?
