HP ProLiant Gen8 Troubleshooting Guide Volume I: Troubleshooting

Common problem resolution 19
DIMM installation and configuration guidelines
DIMM population order and configuration is critical in maximizing performance for the system. For more
information, see the server label on the server or the server user guide on the HP website
(http://www.hp.com/go/hpsc).
Component LED definitions
Many common problems can be identified by reviewing the component and server LEDs. For more
information, see the server and component documentation on the HP website
(http://www.hp.com/go/hpsc).
SAS, SATA, and SSD drive guidelines
When adding drives to the server, observe the following general guidelines:
• Drives must be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
• Drives in the same logical volume must be of the same type. HP SSA and ACU do not support mixing
SAS, SATA, and SSD drives in the same logical volume.
