LSI Corporation (NYSE:LSI) announced that it will be demonstrating the industry’s first 12Gb/s SAS expander IC this week at the LSI Accelerating Innovation Summit and Technology Showcase in Milpitas, Calif. In this demonstration, they will highlight the performance benefits of a 12Gb/s SAS solution with existing 6Gb/s drives compared to an end-to-end 6Gb/s SAS solution using the next-generation LSI 12Gb/s SAS expander and 12Gb/s SAS I/O controller connected to sixteen 6Gb/s SAS HDDs.

The throughput of the 12Gb/s SAS solution with 6Gb/s SAS drives in a PCI Express 2.0 system increased by 65 percent and by 58 percent in IOPS performance compared to the end-to-end 6Gb/s SAS storage solution. LSI believes that 12Gb/s SAS will be essential for maximum performance of next-generation server platforms with PCI Express 3.0 platforms arriving soon and as the enterprise adoption of solid state drives becomes more and more popular.
The 48-port 12Gb/s SAS specifications are as follows:
- Supported data transfer rates: 12Gb/s, 6Gb/s, and 3Gb/s and
- Supported SATA data transfer rates: 6Gb/s and 3Gb/s,
- Supported table routing connections: Up to 2,048 SAS addresses.
- Connect s directly to up to 44 SAS or SATA devices (including HDDs and solid state drives
Using the latest SAS technology, including End Device Frame Buffering (EDFB) technology, the expander is designed to help ease the industry’s transition to12Gb/s SAS-enabled systems by enabling customers to take advantage of 12Gb/s speeds while using existing 6Gb/s drives and backplane infrastructure.
Experts predict that the adoption of the 12Gb/s SAS market will begin with the release of individual SAS components and devices, and will start to “gain momentum“ as tier-one OEMs begin production-volume shipments of 12Gb/s SAS-enabled servers and external storage systems. 12Gb/s SAS-enabled servers are estimated to ship by early 2013 and external storage systems by mid-to-late 2013.
