PMC-Sierra Inc. announced an end-to-end Serial Attached SCSI (SAS) architectural solution for network attached and server attached tiered storage applications.

The company unveiled its maxSAS product family that included the 36- and 24-port SAS expandersthe PM8387 SXP 36x3G and PM8388 SXP 24x3G, and the PM8389 SMC-L, a storage enclosure management processor.

The new product family, combined with either the Adaptec AIC-9410 SAS controller or the ASC-48300 SAS host bus adapter, provides storage equipment manufacturers with a complete end-to-end storage systems solution using either SAS or SATA hard disk drives. According to the press release, this fully interoperable and standards-compliant architecture offers system integrators a time-to-market advantage with reduced hardware and software development and a lower BoM cost.

Highest density port count

The SXP 36x3G and SXP 24x3G devices provide highly integrated, scalable and reliable storage solutions, increased system performance, and higher capacity with an embedded MIPS-Powered storage enclosure processor, complete with a SCSI Enclosure Services (SES) software development kit (SDK). Both expanders have the industry's highest density port count, on-chip I/O termination and a low-latency, fully non-blocking switching architecture, added PMC-Sierra. In addition, they provide high density table routing, with 1,024 entries, enabling storage system architectures to scale to hundreds of SAS and SATA hard disk drives with a low latency, high performance connection.

The SXP 12x3G is targeted at server storage applications and integrates table, direct and subtractive routing along with a SSP virtual port and IPMB interface to external storage enclosure processors. Meanwhile, the SXP 6x3G is targeted at low cost, space constrained, server motherboard applications. The QuadSMX 3G supports the extension of internal server storage connections by providing a robust, reliable SAS and SATA JBOD connectivity over long cable lengths.

For applications requiring a low cost, discrete enclosure management processor, the SMC-L provides a comprehensive set of integrated storage system peripherals including 4 TWI, 53 GPIO, 2 UARTs and 4 Fan/Tachometer ports.
