Specifications
● Up to 24 DDR4 DIMM slots (12 DIMMs per CPU) for
installing either RDIMMs or LRDIMMs
● Maximum memory speed: 2400 MT/s
● 24 x 32 GB RDIMMs for two CPUs, with a maximum
memory capacity of 768 GB
● 24 x 128 GB LRDIMMs for two CPUs, with a maximum
memory capacity of 3072 GB
● Memory protection technologies: Error Checking and
Correction (ECC), memory mirroring, Single Device Data
Correction (SDDC), memory sparing, and lockstep
NOTE
DIMMs of different types (RDIMMs and LRDIMMs) and specifications
(such as the capacity, bit width, rank, and height) cannot be installed
in one server. That is, all DIMMs on one server must have the same
BOM number. To query the BOM numbers of DIMMs, use
Computing Product Compatibility
● Multiple drive configuration specifications are provided.
For details, see
● Built-in storage:
– Two miniSSDs (SATADOMs)
– Two SD cards
NOTE
The SD card controller integrated on the mainboard groups the two
SD cards into a RAID 1 array to improve data security.
● Drives are hot-swappable.
● The server supports RAID 0, 1, 10, 1E, 5, 50, 6, and 60. It
protects cache data from power failures, and supports
RAID level migration, drive roaming, self-diagnosis, and
web-based remote configuration.
● The mainboard can be configured with a SAS or SAS RAID
controller card (with a maximum of 2 GB cache) to
improve hard disk storage performance and ensure user
data security.
● The RAID controller card does not occupy a standard PCIe
slot, improving system scalability.
NOTE
● If the server is equipped with 12 drives, you can install two or
four 2.5-inch SAS HDDs, SATA HDDs, and SSDs or 3.5-inch SAS
HDDs and SATA HDDs at the rear of the server to expand the
local storage capacity.
● If the server is equipped with 25 drives, you can install three 2.5-
inch SAS HDDs, SATA HDDs, and SSDs at the rear of the server to
expand the local storage capacity.
● If SATADOM SoftRAID is used when NVMe PCIe SSDs are
configured, only the Legacy mode can be selected for the BIOS.
