No. Item Description
1 Hard disk Hard disks are hot-swappable and store data for the RH8100
V3. The FM-D supports a maximum of eight 2.5-inch SAS
HDDs, SATA HDDs, SSDs, or NVMe PCIe SSDs.
2 FM-D The FM-D supports hard disks, RAID controller cards, and a
supercapacitor.
3 Hard disk
backplane
The hard disk backplane provides ports for connecting to hard
disks and RAID controller cards.
4 Supercap
acitor
The supercapacitor provides power failure protection for a
RAID controller card with the LSISAS3108 chip.
5 FIO-D The FIO-D houses a RAID controller card and provides the
management function.
6/7 RAID
controller
card
The FM-D supports SR430C (LSISAS3108) RAID controller
cards, and supports multiple RAID levels, RAID level
migration, and drive roaming.
SR430C (LSISAS3108) RAID controller cards supports RAID 0,
1, 5, 6, 10, 50, and 60, and supercapacitors for power failure
protection.
The FM-D supports two RAID controller cards, which are
congured for dierent compute modules.
● RAID-1 is
congured for compute module 1.
● RAID-2 is congured for compute module 5.
NOTE
● If compute module 1 or 5 is not installed, the corresponding RAID
controller card is unavailable.
● NVMe PCIe SSDs do not support RAID. If NVMe PCIe SSDs are
installed in all disk slots, no RAID controller cards need to be
congured on the server.
