HBA Features
The internal Sun Storage 6 Gb SAS PCIe HBA (SGX-SAS6-INT-Z, SG-SAS6-INT-Z) provides a low-cost, PCI Express SAS solution for computer manufacturers. The HBA uses either a standard or low-profile PCI bracket type and has the following features:
Support for over 800 single-pathed, or 400 dual-pathed, internal physical disks that can be accessible by the HBA (for supported configurations, see the storage device documentation)
Support for RAID levels 0, 1, and 10
Support for a maximum of two logical RAID volumes that can be provided by the HBA
Support for a maximum of 10 physical devices within any single RAID volume and a maximum of fourteen physical devices within all RAID volumes combined
PCI Express interface that is compatible with the PCI Express Specification, revision 2.0 and backward compatible with the PCI Express Specification, revision 1.1
Implementation of the PCI Express interface as an x4 or x8 interface
Compatibility with the PCIe Low Profile standards
PCI Express transmission and reception data rate that is 5.0 Gb/s in each direction, yielding a total bandwidth of 10 Gb/s for each full-duplex lane
Simplified cabling with a point-to-point, serial architecture
Smaller and thinner cables that promote unrestricted airflow
Serial, point-to-point, enterprise-level storage interface
SAS/SATA Features
The following are the SAS/SATA features supported by the HBA:
Serial SCSI protocol (SSP), serial ATA tunneling protocol (STP), and serial management protocol (SMP), as defined in the Serial Attached SCSI (SAS) Specification, version 2.0
SAS interface that is compatible with the ANSI Serial Attached SCSI Specification, revision 2.0 and the Serial ATA Specification, revision 2.6
Capability of running with either four or eight serial ports for connection to SAS/SATA (Serial ATA) devices
Each serial port is capable of 6.0 Gb/s SAS and SATA link rates and 1.5 Gb/s or 3.0 Gb/s SATA link rates
Note - While each serial port is capable of 6 Gb/s SAS and SATA link rates, only four of the eight serial ports can operate at 6 Gb/s link rates at one time. This is to accommodate platforms that are not designed for 6 Gb/s operation.Support for the easy addition of SAS interfaces to any computer, workstation, or server with a PCI Express bus
Four or eight PCIe PHYs, which provide possible host-side maximum transmission and reception rates of up to 4 Gb/s
Narrow and wide ports
SATA target devices, as defined in the Serial ATA Specification, version 2.6
Transfer of data using SCSI information units
