performance in a server with a 4-core processor, there should be twice as much memory available as for a
2-core processor.
Backup Drives
— Backup drives help you protect your data. IBM offers several choices of capacities and
technologies, including
DDS-5
,
DDS-6
,
LTO-3
,
LTO-4
, and
GoVault
.
Hard Disk Drives
— IBM hard disk drives help you improve the transaction and cost performance of your
System x servers. The choice of hard disk drives can be a critical aspect of maximizing the I/O throughput
of the system.
SAS
2.5-inch hard disk drives are available for the x3400 M2 with capacities up to
300GB
apiece
at
10,000
RPMs or up to
146.8GB
apiece at
15,000
RPMs.
Power Supply
— The optional second power supply for the x3400 M2 enables redundancy for hot-swap
power. In addition, its 90%-efficient design helps lower your energy bill for power and cooling.
IMM Virtual Media Key
— The x3400 M2 includes a plethora of systems management features built-in.
The optional IMM Virtual Media Key not only offers powerful new features, it does so without taking up a
valuable PCIe or PCI-X adapter slot, instead using a dedicated connector on the motherboard.
ServeRAID Controllers
— System x servers using ServeRAID technology allow companies to build a
reliable foundation for business-critical computing. IBM ServeRAID technology allows an array consisting
of multiple physical hard disk drives to be treated as one logical drive. ServeRAID technology also allows
data to be stored redundantly, across multiple hard disk drives— enhancing both the integrity and the
availability of the data. SAS and SATA ServeRAID controllers offer enhanced performance due to onboard
processors and cache. Because IBM ServeRAID controllers can help significantly improve data transfer
rates, this technology is extremely effective when implementing demanding, transaction-oriented
applications. By employing the advanced fault tolerance of IBM ServeRAID technology, companies can
effectively implement networked business systems that require large amounts of storage space for data
and applications that must be available for their businesses to continue operating.
The optional
ServeRAID-MR10i SAS/SATA
controller offers enhanced performance over the integrated
ServeRAID-BR10i
controller (SAS models),
256MB
of battery-backed cache memory, and supports
eight
RAID levels:
0
(striping),
1
(mirroring),
10
(mirroring and striping),
1E
(enhanced mirroring, supporting odd
numbers of drives),
5
(striping with parity),
50
(striping/mirroring with parity),
6
(striping with dual-parity),
and
60
(striping/mirroring with dual-parity).
The optional
ServeRAID-MR10is
supports hardware-based
full disk encryption
plus
RAID-
0/1/1E/10/5/50/6/60
support.
The optional
ServeRAID
-
MR10M SAS
controller offers high performance and
256MB
of cache memory
(with optional battery backup) for
external
SAS storage capacity. The adapter supports
RAID-
0/1/10/5/50/6/60
.
External Storage
— The
IBM
System Storage DS3000, DS4000, DS6000,
and
DS8000
series, as well
as the
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 System Storage
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.
