This chapter provides a general overview of the Intel® RAID Controller SRCSAS144E. It consists of the following sections:

Summary of SAS RAID Controller Features

Benefits of Serial Attached SCSI (SAS)

The Intel® RAID Controller SRCSAS144E Storage Adapter is a high-performance intelligent PCI Express* SAS RAID controller. It provides reliability, high performance, and fault-tolerant disk subsystem management. This is an ideal RAID solution for the internal storage needs of workgroup, departmental, and enterprise systems. The RAID Controller SRCSAS144E offers a cost-effective way to implement RAID in a server for internal and external storage.

The SAS controller allows you to use SATA and SAS hard disk drives in the same system, so you can take advantage of the benefits of each type of drive. The controller can connect up to eight drives directly and use expanders to connect to additional drives. See the ANSI SAS standard, version 1.0 specification for more information about the use of expanders.

As the second generation PCI Express storage adapter, the RAID Controller SRCSAS144E addresses the growing demand for increased data throughput and scalability requirements across midrange and enterprise-class server platforms. Simplified cabling between drives is an additional benefit.

The optional Intel® RAID Smart Battery for cached data protection allows system builders to protect cached data during catastrophic system failures.

Summary of SAS RAID Controller Features

Note: In this document, the term low-profile refers to the height, not the length, of a PCI add-in card.
