SAS/SATA Drive Support

The Intel® Tri-Mode RAID Modules are designed to support SAS, SATA and NVMe drives; however, if desired,
they can be used to connect only SAS and SATA drives. In this case, standard SAS cables and backplanes can
be used (make sure to use only those backplanes which have been tested and listed as compatible hardware).
The Intel® Tri-Mode RAID Modules support the ANSI Serial Attached SCSI standard, version 3.0. In addition,
the modules support the SATA III protocol defined by the Serial ATA specification (SAS), version 3.0. Supporting
both the SAS interface and the SATA interface, the SAS module is a versatile module that provides the
backbone of both server and high-end workstation environments.
Each port on the RAID Module supports SAS devices, SATA devices, or both, through these protocols:
SAS Serial SCSI Protocol (SSP), which enables communication with other SAS devices
•
SATA, which enables communication with other SATA devices
•
Serial Management Protocol (SMP), which communicates topology management information directly
•
with an attached SAS expander device, and
Serial Tunneling Protocol (STP), which enables communication with SATA devices through an attached
•
expander.
SAS technology brings a wealth of options and flexibility with the use of SAS devices and SATA devices within
the same storage infrastructure. However, SAS devices and SATA devices bring individual characteristics that
make each one a more suitable choice depending on the requirements of the given operating environment
and storage needs. The Intel® Tri-Mode modules provides the flexibility to combine these two (2) storage
technologies on the same module and within the same enclosure.
Note: combining SAS drives and SATA drives within the same virtual drive is allowed on some modules but
Intel discourages this practice.
