Figure 36. M.2 storage device connectors
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 #1 is supported by PCIe x2
bus lanes and sSATA-2 from the chipset embedded sSATA controller.
M.2 connector pinout definition is only made available by obtaining the board schematics directly from Intel
(NDA required).
6.3.1.1
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.
Note: NVMe RAID support using Intel RSTe and Intel 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).
Note: The Intel ESRT2 option does not support PCIe devices.
•
Both Intel ESRT2 and Intel RSTe provide RAID support for SATA devices (see Section 6.3.6).
•
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 Intel RSTe or Intel ESRT2
cannot span across the two embedded SATA controllers nor is mixing both SATA and NVMe devices within a
single RAID volume supported.
•
The binary driver includes partial source files. The driver is fully open source using an MDRAID layer
in Linux*.
