Storage Support
The Intel® Server Board M50CYP2SB family provides storage options not available on previous server board
generations.
The server board supports up to two server board mounted M.2 PCIe*/SATA SSDs. The server board Mini-
SAS HD (SFF-8643) connectors provide SATA SSD storage support.
The server board also provides various Non-Volatile Memory Express (NVMe*) storage options. NVMe*
is an
optimized, high-performance scalable storage interface designed to address the needs of enterprise systems
that use PCIe*-based solid-state storage,
providing efficient access to non-volatile memory storage devices.
The NVMe* technology allows Intel server boards to take advantage of the levels of parallelism possible in
modern SSDs.
Additional Intel® VROC NVMe* and Intel® VROC SATA capabilities are available. The Intel® Server Boards
support Intel® VROC 7.5.
Support for different storage options varies depending on the configuration and/or available accessory
options installed. This chapter provides an overview of server board storage support.

Server Board SATA Support
The server board uses two chipset-
embedded AHCI SATA controllers, identified as “
S
ATA” and “sSATA”
. The
AHCI sSATA
controller supports up to two 6 GB/s SATA III ports (sSATA 1 and sSATA 2) using two M.2 SSD
connectors. The AHCI SATA controller supports up to eight 6 GB/s SATA III ports on the server board. The
following table describes the SATA and sSATA feature support.
