IBM System x3400 M3 Product Manual page 12

The engine of growth for your emerging businesses.
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 LTO-5 tape solutions, and
the RDX Removable Disk Cartridge drive (both internal and external).
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. For x3400 M3 systems with 2.5-inch bays, SAS HDDs are available in
capacities up to 600GB apiece at 10,000 RPMs or up to 146.8GB apiece at 15,000 RPMs. For large
capacity nearline requirements, up to 2TB 7,200 RPM 3.5-inch SAS and SATA drives are supported.
For systems with 3.5-inch bays, SAS HDDs are available with capacities up to 600GB at 15,000
RPMs; SATA drives are available in capacities up to 2TB at 7,200 RPMs.
Power Supply — The optional second power supply for the x3400 M3 enables redundancy for hot-
swap power (model dependent). In addition, its 90%-efficient design helps lower your energy bill for
power and cooling.
IMM Virtual Media Key — The x3400 M3 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 ServeRAID-BR10il V2 SAS/SATA Controller offers RAID-0/1/1E support, with up to 3Gbps
per port. The IBM ServeRAID-M1015, x8 PCIe and 6Gbps, offers RAID-0/1/10; optionally RAID-5
with SED support. The IBM ServeRAID-M5014, x8 PCIe and 6Gbps, provides 256MB cache and
RAID-0/1/10/5/50; optionally RAID-6/60 with SED, and battery backup). The IBM ServeRAID-M5015,
x8 PCIe and 6Gbps, has 512MB cache and RAID-0/1/10/5/50; optionally RAID-6/60 with SED, and
battery backup. For external storage, the ServeRAID-MR10M controller provides RAID-0/1/10/5/50
support and 256MB of onboard cache and enables connection to up to four IBM System Storage
EXP3000 SAS expansion units (48 HDDs total). The IBM ServeRAID M1000 Series Advance
Feature Key adds RAID-5 and SED support to the ServeRAID-M1015. Similarly, the IBM
ServeRAID M5000 Series Advance Feature Key adds RAID-6/60 with SED support to the M5014
and M5015. The IBM ServeRAID M5000 Series Battery Key adds battery backup support to the
M5014.
External Storage — The IBM System Storage EXP810 expansion units, as well as the DS3000,
DS4000, and DS8000 series storage subsystems and N3000, N5000, N6000, and N7000 NAS
systems comprise a powerful and broad shared storage family with integrated management software
designed to meet midrange and enterprise needs.
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.
