The LSISASx28 is a 28-port 3Gb/s Serial Attached SCSI (SAS) expander with

an Integrated ARM processor for Enclosure Management and extended SAS

Direct, Subtractive decode, and table

routing methodologies supported

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.

Provides a scalable interface that

supports up to 1024 SAS addresses

Supports wide and narrow port configurations

– Allows reuse of routing table resources

across all of the PHYs composing a

wide port

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.

– Allows any number of PHYs for wide

port support

PHY-based zoning for system security

SATA/SAS HDD spin-up sequencing,

configurable on a per-PHY basis

SGPIO (SFF-8485) support

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.

8 GPIO pins

3 LEDs per PHY

– Link status, drive activity

fault LED outputs

– Can be used as GPIOs

Integrated ARM processor

– SEP functionality

– Drive management

– Extended SAS SMP functions
