Item Specifications
Memory Up to 16 DDR4 DIMM slots (8 DIMMs per CPU) for installing either
RDIMMs or LRDIMMs
l 16 x 32 GB RDIMMs for two CPUs, with a maximum memory
capacity of 512 GB
l 16 x 128 GB LRDIMMs for two CPUs, with a maximum memory
capacity of 2048 GB
l Maximum memory speed: 2400 MT/s
l 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 in one server must have the same BOM number. To query the BOM
numbers of DIMMs, use the Huawei Server Compatibility Checker.
Storage
l Multiple hard disk configuration specifications are provided. For
details, see 2.1 Introduction.
l Hard disks are hot-swappable.
l 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.
l The mainboard can be configured with a SAS adapter or SAS RAID
controller card (with a maximum of 2 GB cache) to improve hard
disk storage performance and ensure user data security.
l The RAID controller card does not occupy a standard PCIe slot,
improving system scalability.
NOTE
l If the server is equipped with 12 hard disks at the front, 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.
l If the server is equipped with 25 hard disks at the front, 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.
l If SATADOM SoftRAID is used when NVMe PCIe SSDs are configured,
only the Legacy mode can be selected for the BIOS.
