SAS2308 Datasheet, PDF (2/2 Pages) Broadcom Corporation. – PCI Express to 8-Port 6Gb/s SAS/SATA Controller

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-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.
