LSISAS1064E

Product Summary

The LSISAS1064E is a four-port 3.0Gb/s Serial Attached SCSI (SAS) controller that is based on the Fusion-MPT. (Message Passing Technology) architecture and provides an eight-lane PCI Express interface. The LSI Logic SAS integrated controller provides 1.5 and 3.0Gb/s SAS and SATA data transfer rates per port and enables Integrated RAID solutions in storage environments including servers, workstations, blade servers and external storage systems. The LSISAS1064E is ideal for today data centers and leverages existing SCSI infrastructure for investment protection. The LSISAS1064E complies with the PCI Express 1.0a specification and supports 8 PCI Express lanes at 2.5Gb/s, full duplex, for an aggregate bandwidth of up to 4GB/sec. The LSISAS1064E can be configured as a PCI Express x8, x4, or x1 device, supporting auto-negotiation among those link widths. For example, if the LSISAS1064E is configured for 8 lanes and is plugged into a x8 connector that is wired as a x4, the LSISAS1064E will automatically negotiate to a x4 link width. The PCI Express architecture is an industry standard high-performance, general-purpose serial I/O interconnect utilizing a cost-effective, low-pin count interface offering high bandwidth per pin. For investment protection and ease of development migration, it retains PCI compatibility by using the established PCI software programming models, thus facilitating a smooth transition to new hardware while allowing software to evolve to take advantage of PCI Express features.
