M.2 SSD Support
The Intel® Server Board S2600WF product family includes two M.2 SSD connectors labeled
“M2_x4PCIE/sSATA_1” and “M2_x2PCIE/sSATA_2” on the server board as shown below.
Figure 64. M.2 module connector locations
Each M.2 connector can support PCIe* or SATA modules that conform to a 2280 (80 mm) form factor.
PCIe bus lanes for each connector are routed from the Intel chipset and can be supported in single processor
configurations.
The M.2 connector to the left of Riser Slot #1 is supported by
PCIe x4
bus lanes and
sSATA-1
from the
chipset embedded sSATA controller. The M.2 connector to the right of Riser Sot #1is supported by
PCIe x2
bus lanes and
sSATA-2
from the chipset embedded sSATA controller.
7.3.1
Embedded RAID Support
RAID support from embedded RAID options for server board mounted M.2 SSDs is defined as follows:
Neither Intel® ESRT2 nor Intel® RSTe have RAID support for PCIe* M.2 SSDs when installed to the M.2
connectors on the server board.
o
Note:
NVMe RAID support using Intel® RSTe VROC requires that the PCIe bus lanes be routed
directly from the CPU. On this server board, the PCIe bus lanes routed to the on-board M.2
connectors are routed from the Intel chipset (PCH).
o
Note:
The Intel® ESRT2 onboard RAID option does not support PCIe devices.
Both Intel® ESRT2 and Intel® RSTe provide RAID support for SATA devices
Neither embedded RAID option supports mixing of M.2 SATA SSDs and SATA hard drives within a
single RAID volume
Note
: Storage devices used to create a single RAID volume created using either RSTe or ESRT2, cannot span
across the two embedded SATA controllers nor is mixing both SATA and NVMe devices within a single RAID
volume supported.
Open Source Compliance = Binary Driver (includes Partial Source files) or Open Source using MDRAID
layer in Linux*
