featured RAID implementation is cost

prohibitive or not desired. LSI’s ad-

vanced Integrated RAID options include

Integrated Mirroring (IM), which is RAID

1, Integrated Mirroring Enhanced (IME),

known as RAID 1E, Integrated Striping

(IS), which is RAID 0, and Integrated Mir-

roring and Striping (IMS) which is RAID

10. By simplifying the RAID configuration

options, Integrated RAID is easy to install

and configure and meets the needs of

most internal RAID requirements.

LSI provides a complete suite of in-

dustry while reducing time to market,

integration, standard operating system

drivers. LSI also supports Virtual Operat-

ing Sytems with device emulation and

para-virtualization in support of the

emerging SR-IOV technology.

Fusion-MPTArchitectureOverview

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.
