LSISAS2108 Description

Short technical summary and product information.

The LSISAS2108 from LSI Corporation is a second-generation Serial Attached SCSI (SAS) RAID-On-a-Chip (ROC) device, built on four generations of ROC technology and the Fusion-MPT architecture. It integrates the latest enhancements in SAS and PCI Express technology, supporting 8 PCIe lanes and complying with the PCI Express 2.0 specification for data rates up to 5.0 GT/s per lane.

This 8-port ROC controller supports SAS and SATA data transfer rates of 1.5, 3, and 6Gb/s per lane. It offers integrated RAID features, supporting RAID levels 0, 1, 1E, and 10 with MegaRAID support, and levels 0, 1, 5, 6, 10, 50, and 60 with up to 240 disk support. The device includes a high-performance PowerPC 440 processor running at up to 800MHz, with hardware acceleration for RAID 5 and RAID 6 parity calculations.

Key features include End-to-End CRC (ECRC) with Advanced Error Reporting (AER), Spread Spectrum Clocking (SSC) for EMI reduction, and a 72-bit, 800MHz, ECC protected DDR2 SDRAM interface. The LSISAS2108 is designed for entry to mid-range servers, providing a robust and interoperable SAS solution.
