memory to a System x server is one of the most effective ways to increase application
performance. For best performance in a server with 8-core processors, there should be twice as
much memory available as for a 4-core processor. The x3755 M3 takes memory upgrades in
pairs and provides two-way interleaving. (Note: Each processor provides 8 DIMM slots.)
Power Supplies — With two processors installed, the optional 1100W second power supply for
the x3755 M3 enables redundancy for hot-swap power. When four processors are installed, two
hot-swap power supplies are required; a third provides redundancy. (Redundant power supplies
are available via CTO only.)
Fans — Hot-swap/redundant fans are provided standard. Nonredundant fans are available as
an alternative, via the configure-to-order process only.
Hard Disk Drives — IBM hard disk drives help customers improve the transaction and cost
performance of their System x servers. The choice of hard disk drives can be a critical aspect of
maximizing the I/O throughput of the system. Hot-swap SAS hard disk drives (3.5-inch) are
available for the x3755 M3 in capacities of 300, 450, or 600GB at 15,000 RPMs and 1 or 2TB at
7,200 RPMs. Hot-Swap SATA hard disk drives (3.5-inch) are available in capacities of 250 and
500GB, and 1 or 2TB, at 7,200 RPMs. Simple-Swap SATA hard disk drives (3.5-inch) are
available in capacities of 250 and 500GB, or 2TB, at 7,200 RPMs.
IBM 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 IBM ServeRAID-M1015, x8 PCIe and 6Gbps, offers RAID-0/1/10; optionally RAID-5/50 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-
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 and battery backup. The IBM ServeRAID
M1000 Series Advance Feature Key adds RAID-5/50 support to the ServeRAID-M1015.
Similarly, the IBM ServeRAID M5000 Series Advance Feature Key adds RAID-6/60 and SED
support to the M5014 and M5015. The IBM ServeRAID M5000 Series Battery Key adds battery
backup support to the M5014.
