The LSISASx28 is a 28-port 3Gb/s Serial Attached SCSI (SAS) expander with
an Integrated ARM
SMP functions. This device offers enhanced Enclosure Services such as drive
management and supports many options for implementing enclosure man-
agement, including a backward compatible interface to an external processor
using existing code or implementing the internal processor using SSP target.
Phy-based zoning is also supported for network storage security applications.
processor for Enclosure Management and extended SAS
The LSISASx28 expander is compliant with the ANSI Serial Attached SCSI
specification and supports SATA as defined in the Serial ATA: High Speed
Serialized AT Attachment and the Serial ATA II: Port Selector Specification.
SAS benefits include improved performance, simplified cabling, smaller
connectors, a lower pin count, and lower power requirements. In addition,
SAS leverages an electrical and physical connection interface that is compatible
with SATA technology. The interface compatibility allows for customer flexibility
in drive connection including the 2.5” hard disk drive small form factor.
The LSI Logic 28-port expander provides large storage environments the ability
to connect multiple targets and initiators through a switched device for
scalability and fault-tolerant path-redundancy to improve system reliability.
This is ideal for today’s data center and storage subsystems, leveraging
existing SCSI infrastructure for investment protection and ease of migration
and implementation.
