Configuration notes:
All RDIMMs in the server operate at the same speed, which is determined as the lowest value of:
RDIMM rated speed (2666 MHz or 2933 MHz).
Memory speed supported by the specific processor (2133 MHz, 2400 MHz, 2666 MHz, or 2933
MHz).
Note:
Maximum memory speed can be achieved when Max performance mode is enabled in UEFI.
Mixing RDIMMs of different ranks (single- or dual-rank), DRAM chip types (x4 or x8), speeds (2666 MHz or
2933 MHz), and capacities (8 GB, 16 GB, 32 GB, or 64 GB) is supported in the independent channel mode
(the default operational mode).
For server configurations with memory protection, the following rules apply:
Single Device Data Correction (SDDC) works only in the independent channel mode and supports
only x4-based memory DIMMs.
Adaptive Double Device Data Correction (ADDDC) works with x4-based memory DIMMs and
requires two DIMM ranks per channel, Intel Xeon Gold or Platinum processors, and the Closed
Page memory access mode.
If memory mirroring is used, then DIMMs must be installed in quantities of 2 or 4 per processor for
mirroring across two memory channels, or in quantities of 3 or 6 per processor for mirroring across
three memory channels. Mixing two- and three-channel mirroring in the server is allowed (one
processor uses two-channel mirroring, and another processor uses three-channel mirroring). All
DIMMs in the server must be identical in type and size.
If memory rank sparing is used, then a minimum of two ranks must be installed per populated
channel (a least one dual-rank or quad-rank DIMM; single-rank DIMMs are not supported). With rank
sparing, one rank in each populated channel is reserved as spare memory for other ranks on the
same channel. All DIMMs in the server must be identical in type and size.
SDDC, memory mirroring, and memory rank sparing modes are mutually exclusive. Only one
operational memory mode can be enabled on the server.
Internal storage
The SR550 server supports the following internal drive bay configurations:
1. 8 LFF SATA Simple Swap drive bays
2. 8 LFF SAS/SATA hot-swap drive bays
3. 12 LFF SAS/SATA hot-swap drive bays
4. Up to 16 SFF hot-swap drive bays: 8x 2.5" SAS/SATA + 8x 2.5" SAS/SATA
