LSI offers a complete selection of inter-

nal RAID product offerings for direct

attached storage (DAS) connectivity

and RAID-on-Motherboard (ROMB)

solutions. Integrated RAID (R0, 1, 1E, 10)

is a low cost, high performance RAID

solution designed for system environ-

ments requiring redundancy and high

availability where a full featured RAID

implementation is cost prohibitive or

not required.

For applications that require a full

featured RAID implementation,

MegaRAID® hardware RAID (0, 1, 5, 6,

10, 50, 60) is ideal for high performance

and high availability applications. In

addition to offering a complete suite of

RAID offerings, LSI also offers upgrade

paths from our low cost RAID solutions

to our full featured RAID enabled with

an activation key.

For ease of use, the LSI RAID products

are managed under a common man-

agement utility, MegaRAID Storage

Manager (MSM™).

LSI provides a complete suite of indus-

try standard operating system drivers.

Fusion-MPT Architecture Overview

Fusion-MPT architecture marks the next

generation of I/O architecture designed

to deliver the highest performance

available today while reducing time

to market, integration, and certifica-

tion time. Fusion-MPT devices are high

performance, cost-effective protocol

controllers that represent the newest

system- level integration technology in

intelligent I/O processors from LSI.
