1 Introduction
The Astek A33606-PCI-60-6A expander provides 36 lanes for connection to SAS/SATA devices
and/or hosts. Each lane is capable of 1.5Gb/s, 3.0Gb/s, or 6Gb/s operation. The A33606-PCI-60-
6A contains two SFF-8088 external miniSAS connectors and seven SFF-8087 internal miniSAS
connectors. Each connector contains four SAS/SATA lanes. Each internal miniSAS connector also
includes SGPIO sideband signals for the respective lanes on the connector.
The A33606-PCI-60-6A is designed to be installed in a PCI, PCI-X or PCIe slot. The PCI slot
provides a mechanical mounting location for the board; no signal or power pins are used. The
A33606-PCI-60-6A is also available without a PCI bracket for mounting directly to a chassis or with
a 5.25” shell for mounting in a 5.25” bay on a traditional PC chassis.
The Astek expander SAS interface is compatible with the ANSI Serial Attached SCSI Specification,
revision 2.0 and the Serial ATA Specification, revision 2.6. The functionality of the expander board
comes from the LSISAS2X36 expander chip. The expander card makes it easy to add additional
SAS/SATA drive support to RAID and JBOD systems. The expander card support narrow port and
wide port operation. Wide port size is not limited by the expander. Typical port sizes are listed in
the table below.
Number of SAS lanes Speed
Narrow Port (1 lane) 600 MB/s
Wide Port (4 lanes) 2400 MB/s
Wide Port (8 lanes) 4800 MB/s
