LSISAS1068 - PCI-X to 8-port 3 Gb/s SAS Controller

Datasheet Summary

Description

Figure 3 provides the block diagram for the LSISAS1068 controller.

The following subsections discuss the block diagram.

There is a single Host Interface module and 2 Quad Port modules.

Features

  • a performance based message passing protocol that offloads the host CPU by completely managing all I/Os and minimizes system bus overhead by coalescing interrupts. The Fusion-MPT architecture requires only thin, easy to develop device drivers that are independent of the I/O bus. LSI Logic provides these device drivers. To meet its flexibility and data transfer requirements, the LSISAS1068 uses an ARM966 processor that operates at 225 MHz. LSI Logic manufactures the LSISAS1068 controller using Gflx™.

LSISAS1068 8-Port, 3 Gbit/s Serial Attached SCSI Controller Datasheet Version 2.0 The LSISAS1068 is an eight, port 3.0 Gbit/s SAS/SATA controller that is compliant with the Fusion-MPT™ architecture, provides a PCI-X interface, and supports Integrated RAID. Each of the eight phys on the LSISAS1068 is capable of 3.0 Gbit/s and 1.5 Gbit/s link rates. The user can configure ports as wide or narrow. Narrow ports have one phy per port. Wide ports have between two and four phys per port. Each port supports the SSP, SMP, STP, and SATA protocols. www.DataSheet4U.com The SAS interface uses the proven SCSI command set to ensure reliable data transfers, while providing the connectivity and flexibility of point-topoint serial data transfers.
