Intel® RAID Controller SRCSASPH16I Hardware Guide 2
The SAS controller supports the ANSI Serial Attached SCSI (SAS) standard, version 1.0.
In addition, the controller supports the Serial ATA (SATA) protocol defined by the Serial
ATA specification, version 1.0a.T he SAS controller is a versatile controller that
supporting both the SAS and SATA interfaces and provides the backbone of both server
and high-end workstation environments.
Protocols supported include:
• Serial SCSI Protocol (SSP): Communication with other SAS devices.
• SATA II Protocol: Communication with other SATA II devices.
• Serial Management Protocol (SMP): Topology management information sharing with
expanders.
• Serial Tunneling Protocol (STP) support for SATA II through expander interfaces.
Usability
• Smaller, thinner cabling with serial point-to-point 3.0 Gbps data transfer rates.
• Allows mixed connections to SAS or SATA targets.
• Support for non disk devices and mixed capacity drives.
• Support for intelligent XOR RAID levels 0, 1, 5, 6, 10, 50 and 60.
• Dedicated or global hot spare with auto rebuild if an array drive fails.
• User defined stripe size per drive (8, 16, 32, 64 (def), or 128 KB).
• Advanced array configuration and management utilities that provide:
— Online Capacity Expansion (OCE) adds space to existing drive or new drive.
— Online RAID level migration (upgrade of RAID mode, may require OCE).
— Drive migration.
— Drive roaming.
— No reboot necessary after expansion.
• An upgradeable Flash ROM interface.
• Allows for staggered spin up, hot plug, lower power consumption.
