Overview
This chapter provides a general overview of the Intel
®
RAID Controller SASUC8I. It
consists of the following sections:
•
Summary of SAS RAID Controller Features
•
Benefits of Serial-Attached SCSI (SAS)
The Intel
®
RAID Controller SASUC8I is a PCI Express* SAS RAID controller. It
provides reliable and fault-tolerant disk subsystem management. This is an ideal RAID
solution for the internal large capacity storage needs of mid to low-end servers and
workstations for use by workgroups and departmental-sized organizations or individuals.
The Intel
®
RAID Controller SASUC8I 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; however, Intel
does not recommend mixing SAS and SATA II drives in the same enclosure.. The
controller supports up to 14 physical devices in IR mode and up to 122 devices, including
expander devices, in IT (non-RAID) mode. For more information about the use of
expanders, see the
ANSI SAS Standard Specification, Version 1.0
.
As the second generation PCI Express* storage adapter, the Intel
®
RAID Controller
SASUC8I 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.
The Intel
®
RAID Controller SASUC8I is a low-profile SAS RAID adapter with:
•
An LSI* 1068E SAS (including SATA) controller.
•
Eight independent internal ports provided via two SFF8087 connectors.
•
Support for both enterprise-class SAS devices and enterprise-class SATA II drives.
•
Support for up to 14 SAS or SATA II drives and 2 logical drives in IR mode.
•
PCI Express* connector that fits into a x8 PCI Express* (or larger) slot capable of
2.5 Gbps per lane over PCI Express* x1, x4, or x8.
•
3.0 Gbps point-to-point transfer rate.
•
Both a standard and a low-profile bracket.
