New generation PHY enables Serial ATA II solution
The 88SA8050 bridge chip is the industry's first 3Gbit/s Serial ATA II solution enabling the highest throughput SATA storage systems available.
The low cost and high capacity of ATA-based hard disk drives (HDDs) also provides new options for data backup using near-line storage to complement traditional tape backup systems.
"Serial ATA technology is already becoming a significant force in the development of lower cost server and external disk storage systems, and is ramping in share as the market leaders in these spaces continue to introduce Serial ATA based systems into their product lines", said Sean Lavey, a Semiconductor Analyst with IDC.
"The introduction of Serial ATA II based silicon should accelerate this trend as it provides critical performance improvements necessary for adoption in a wider range of enterprise environments".
"We are seeing strong adoption of Serial ATA technology in the market-leading vendors for servers, RAID adapters, enterprise RAID arrays and near-line storage", said Balaji Baktha, General Manager of Marvell's Storage Networking Business Unit.
"Marvell's Serial ATA II solutions provide these customers a platform to develop a host of next generation enterprise applications".
The 88SX60xx controllers implement Marvell's second-generation Serial ATA physical layer (PHY) technology that supports both 1.5 and 3.0Gbit/s operation for high performance Serial ATA backplane implementations.
Spread spectrum clocking (SSC) provides optimal EMI performance for lower enclosure costs and easier system certification.
Operation at 3.0Gbit/s enables plug-and-play support for next generation Serial ATA II 3.0Gbit/s hard drives.
Serial ATA II port multiplier support allows aggregation of multiple 1.5Gbit/s Serial ATA links into a single 3.0Gbit/s host port for high-density storage enclosures using next generation 2.5in form factor drives.
The 88SX60xx devices implement Serial ATA II native command queuing (NCQ) significantly increasing performance on enterprise applications such as e-mail servers and databases that rely heavily on random accesses.
The 88SX60xx devices also support Serial ATA I/ATA-6 tag command queuing (TCQ) used in Marvell's first generation 88SX50xx Serial ATA host controllers allowing full interoperability with today's high-performance Serial ATA I TCQ drives.
The 88SX60xx software application programming interface (API) compatibility with Marvell's first generation Serial ATA I host controllers enables rapid migration to Serial ATA II technology.
In addition, the API uses a SCSI programming model, allowing SCSI applications to be easily ported to Serial ATA HDD subsystems.
Reduced software development cycles offer OEMs using Marvell solutions a significant time to market advantage in a competitive market environment.
