Intel® RAID Controller SASMF8I Hardware User’s Guide 1
1 Overview
This chapter provides a general overview of the Intel
®
RAID Controller SASMF8I. It
consists of the following sections:
• Summary of SAS RAID Controller Features
• Benefits of Serial-Attached SCSI (SAS)
The Intel
®
RAID Controller SASMF8I is a high-performance 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 mid to low-
end servers and workstations for use by workgroups and departmental-sized organizations
or individuals. The Intel
®
RAID Controller SASMF8I offers a cost-effective way to
implement RAID in a server for internal storage.
The SAS controller allows you to use SATA II and SAS hard disk drives in the same
system, so you can take advantage of the benefits of each type of drive. The controller
supports up to eight devices including expander devices. See the ANSI SAS Standard
Specification, Version 1.0 for more information about the use of expanders.
As the second generation PCI Express* storage adapter, the Intel
®
RAID Controller
SASMF8I addresses the growing demand for increased data throughput and scalability
requirements across mid to low-end servers and workstations. Simplified cabling between
drives is an additional benefit.
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.
