SSC200

Enclosure Management

Controller

Product Brief

Overview

The SSC200 is an enclosure management controller

for peripheral storage applications. This device

supports several in-band and out of band

management strategies. The SSC200 can

implement in band SES and SAF-TE enclosure

management on parallel SCSI and Fibre Channel.

Out of band solutions are possible using IPMI or

customer unique approaches.

JBOD and RAID subsystem developers are provided

a common hardware and software platform, which

supports all common subsystem diagnostic and

enclosure management strategies. The SSC200

may be used as the master controller of an I2C serial

interface communicating with scalable slave

backplane controllers such as Vitesse’s

VSC055/050 and other industry standard devices.

SFF-8067 Applications

The SSC200 integrates two SFF-8067 ESI ports and

supporting logic. Internal DMA allows fully

automated high-speed data transfers. No external

logic is required for AL_PA selection. Automated

discovery phase guarantees compliance with the

SFF-8067 specification. Flexible implementation

allows communication with devices, which may not

be compliant with the specification.

Software Development Kit Features

• Modular architecture to support migration to

other I/O technologies and protocols

• Extensive peripheral device library

• Sample Personality Module source code

SCSI Applications

The SSC200 supports two mechanisms for

dedicated port enclosure management across a

parallel SCSI bus. An external SCSI controller can

be connected to the SSC200’s DMA interface to

provide a high performance, two-device SES or

SAF-TE solution. No external components are

required with this approach; the SSC200 integrates

both the DMA buffers and control logic. This

architecture provides system designers with a

common platform for various SCSI bus speeds and
