integrated ServeRAID-8k-l controller (SAS models),
256MB
of battery-backed cache memory,
and supports
six
RAID levels:
0
(striping),
1
(mirroring),
10
(mirroring and striping),
1E
(enhanced
mirroring, supporting odd numbers of drives),
5
(striping with parity), and
6
(striping with double
parity).
The optional
MegaRAID
8480 SAS controller offers high performance and
256MB
of cache
memory (with optional battery backup) for
external
SAS storage capacity. The adapter supports
five
RAID levels:

External Storage
— The
IBM
TotalStorage DS3000, DS4000, DS6000,
and
DS8000
series, as
well as the
System Storage DS4000, N3000, N5000, and N7000
series, comprise a powerful
and broad shared storage family with integrated management software designed to meet
midrange and enterprise needs. For lower-end needs, IBM offers the TotalStorage
DS300
and
DS400
storage enclosures.
External SAN, iSCSI, and direct-attach storage is available using one of several IBM System
Storage and TotalStorage host bus adapters. Additionally, external LAN-attached tape storage is
available.
The
iSCSI HBA Adapter for IXA Connectivity
is a PCI adapter for selected System x and
xSeries servers that provides a direct
1GBps
link to an IBM System i5 or iSeries server. This
connection enables you to centralize your Microsoft Windows and System i5 or iSeries storage
and consolidate the operations and backup of your System x, xSeries, System i5 and iSeries
systems into a single infrastructure. It enables the tightest possible integration between Windows
and System i5/iSeries data and applications, and allows as many as
32
servers to attach to one
System i5 or iSeries system to share the iSeries server’s systems management, DVD, tape and
disk storage via the iSeries dynamic virtual storage architecture. This can take the place of a SAN
if you have an established System i5 or iSeries infrastructure.
