Introducing the SAS Expander Card
SAS expander card expands one SAS address to a number of additional ports. It is an
optimal device for usage in data centers
The CHENBRO 28-port low profile SAS expander card provides high performance, high
disk drive connectivity, scalability and flexibility in various storage environments. It is a
valuable solution to other expansive and complex topologies. The SAS expander is ideal
for high availability, scalable server clustering environments, front-end storage
subsystems used in clusters, SANs and NAS environments.
The CHENBRO SAS Expander is based on LSI SASX28 IC that enables the connection of
multiple drive devices in directly attached SAS or SATA. Each expander PHY performs
SAS and SATA transfer rate at 3.0 Gbit/s or 1.5 Gbit/s with individual configurations.
The SAS expander IC supports the Serial SCSI Protocol (SSP), SATA Tunneled Protocol
(STP) and Serial Management Protocol (SMP). Those are based on SAS protocol and
described in the SAS standard v1.0 and V1.1.
