The Sun Storage 6 Gb SAS ExpressModule HBA (SGX-SAS6-EM-Z, SG-SAS6-EM-Z) provides eight serial Phys for connection to SAS and/or Serial ATA (SATA) devices. Each Phy is capable of 1.5 Gb, 3 Gb, or 6 Gb SAS and SATA link rates. The PCI-Express interface is capable of 5 GT/s per lane in each direction. With eight fully duplexed links, the total becomes 80 GT/s. Note that actual transfer rates are a function of the host system environment. The card is packaged in a single-wide PCIe Module that conforms to the PCIe ExpressModule Electromechanical Specification, Rev. 1.0.
The HBA contains on-board Flash ROM for storing the firmware. The board also includes Hot Plug architecture which allows insertion and removal of the module when the system has been alerted via the Attention Switch. The light-emitting diodes (LEDs) on the HBA report a heartbeat, activity, and fault conditions when detected by the firmware. Fusion-MPT firmware operates the HBA.
The functionality of the HBA comes from the LSISAS2008 controller ASIC. The HBA connects up to eight direct connected SAS/SATA devices to a computer system through the PCIe ExpressModule interface. The HBA controller uses eight PCIe Phys.
The HBA supports the following features:
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
Simplified cabling with a point-to-point, serial architecture
Smaller and thinner cables that promote unrestricted airflow
A serial, point-to-point, enterprise-level storage interface
Data transfers using SCSI information units
Compatibility with SATA target devices
Narrow and wide ports (See 6 Gb SAS Bandwidths)
