Hard drives
Your system supports up to eight 3.5-inch or 2.5-inch hot-swappable hard drives or SSDs.
All hard drives connect to the system board through the hard drive backplane. Hot-swappable hard drives are supplied in hot-
swappable hard drive carriers that fit in the hard drive slots.
CAUTION:
Before attempting to remove or install a hard drive while the system is running, see the
documentation for the storage controller card to ensure that the host adapter is configured correctly to support
hot-swap hard drive removal and insertion.
CAUTION: Do not turn off or reboot your system while the hard drive is being formatted. Doing so can cause a
hard drive failure.
NOTE: Use only hard drives that have been tested and approved for use with the hard drive backplane.
When you format a hard drive, allow enough of time for the formatting to be completed. Be aware that high-capacity hard
drives can take a long time to format.
