Huawei RH8100 V3 - 2.6 RH8100 V3 Logical Structure

The RH8100 V3 provides three front I/O modules:
● The front I/O module of model A (FM-A) provides performance-balanced
conguration.
The FM-A supports a maximum of 12 SAS HDDs, SATA HDDs, or SSDs, two
RAID controller cards, and six standard PCIe slots on PCIe riser cards. The PCIe
slots do not support standard cards that need to connect to external cables,
such as, NICs, HBAs, IBs. You can install PCIe SSDs and GPUs in the slots.
● The front I/O module of model B (FM-B) provides storage-enhanced
conguration.
The FM-B supports a maximum of 24 SAS HDDs, SATA HDDs, or SSDs and
two RAID controller cards. It does not support standard PCIe slots.
● The front I/O module of model C (FM-C) provides low-level
conguration.
The FM-C supports a maximum of eight SAS HDDs, SATA HDDs, or SSDs and
two RAID controller cards. It does not support standard PCIe slots.
● The front I/O module of model D (FM-D) supports NVMe PCIe SSDs.
The FM-D supports a maximum of eight SAS HDDs, SATA HDDs, SSDs, or
NVMe PCIe SSDs and two RAID controller cards, but does not support
standard PCIe slots. 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.
