Good morning, I would like to ask if these dell disk PN are compatible with a PowerVault MD3200 SAN (I did not found them in http://downloads.dell.com/Manuals/Common/MD32XX_MD36XX_SupportMatrix_en-us.pdf 2Tb 12Gb/s 3.5'' SAS disk PN: 400-ALOB (C36WJ) 4Tb 12Gb/s 3.5'' SAS disk PN: 400-ATKM (FW4KG) As I have an empty drive tray (caddy) and found these disks, I would like to ask if it is a tray incompatibility or also a firmware incompatibility ? Thank you, Best Regards
