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

The new maxSAS product family includes what the company claims as the highest density 36 and 24 port SAS expanders (the PM8387 SXP 36x3G and PM8388 SXP 24x3G) and an innovative storage enclosure management processorthe PM8389 SMC-L.

The maxSAS product family, combined with either the Adaptec AIC-9410 SAS controller or 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. 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, PMC-Sierra said. The standards-compliant maxSAS product family also enables a wide range of next-generation RAID, JBOD and server tiered storage systems based on SAS and SATA hard disk drives.

"PMC-Sierra and Adaptec have addressed customers' needs with a low cost, proven turnkey Serial Attached SCSI architectural solution for the growing tiered storage systems market," shared Mark Stibitz, VP and GM of Enterprise Storage Division at PMC-Sierra. "Both companies have worked closely together, along with the storage industry and standards community, to deliver a robust end-to-end solution for the SAS and SATA systems market."

The SXP 36x3G and SXP 24x3G SAS expanders offer increased system performance, higher capacity, scalability and lower BoM costs with an embedded MIPS-powered storage enclosure processor, complete with a SCSI Enclosure Services (SES) software development kit (SDK). Both devices have on-chip I/O termination and a low-latency, fully non-blocking switching architecture. In addition, the SXP 36x3G and SXP 24x3G products 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 specifically 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.
