Outstanding value in a high-performance single-socket tower server

spends in the Turbo Boost Technology state depends on the workload and operating environment,

providing the performance you need, when and where you need it.

In processors implementing Intel Hyper-Threading Technology, each core has two threads capable of

running an independent process. Thus, a 6-core processor can run 12 threads concurrently.

Intelligent Power Capability powers individual processor elements on and off as needed, to reduce

power draw.

Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow attacks

when combined with a supporting operating system.

DDR

ECC Memory

The x3100 M4 ships with one DIMM installed and supports up to 32GB of Unbuffered DIMM (UDIMM)

memory in 4 sockets. It uses PC3-10600 double data rate III (DDR3) memory operating at 1333MHz for

fast access, and provides ECC memory protection.

The x3100 M4 supports either 1, 2, or 4 UDIMMs. When 2 or 4 DIMMs are installed, memory operates

in two-way interleaved mode for increased performance. UDIMMs are available in kits consisting of

one 1GB DIMM or two 1GB, 2GB, 4GB or 8GB DIMMs. The x3100 M4 supports both single- and dual-

rank UDIMMs. RDIMMs and non-ECC memory are not supported. The x3100 M4 supports both single-

and dual-rank UDIMMs. RDIMMs and non-ECC memory are not supported.

Drive Bays

The x3100 M4 contains six drive bays in total, including four 3.5-inch bays that support fixed SATA II

drives and two 5.25-inch bays that support optical or tape drives. The HDD bays support slimline (1.0")

drives, totaling up to 12TB per system, respectively.

A 5.25-inch bay contains a half-height DVD-ROM drive, with a SATA interface, upgradeable to a DVD-

RW drive. A second 5.25-inch bay is available for a half-height tape drive, or an RDX Removable

Disk Cartridge drive. An optional external USB floppy drive may be used, if needed.

Like hot-swap drives, simple-swap drives may be inserted or removed through the front of the server.

Unlike hot-swap drives, simple-swap SATA drives do require powering off the system first; however,

no tools or jumpers are required for installation and removal, allowing for faster, simpler servicing than

fixed drives.

For still more storage, a direct-attach, iSCSI, or SAN external expansion option can be added, using an

optional controller.

Large HDD Storage Capacity

The x3100 M4 supports up to four 3.5-inch fixed SATA II drives:

• 7,200 RPMs —250 or 500GB, 1 or 3TB (12TB maximum capacity)

Note: Enterprise-class 500GB+ SATA drives offer higher reliability and higher performance than lower-

capacity SATA drives.

Disk Controllers

All x3100 M4 models include an integrated SATA II controller in the system chipset. It provides data

transfer speeds of up to 3Gb per second

across the SATA bus for up to four 3.5-inch internal Serial

ATA (SATA) drives. In addition, the x3100 M4 includes RAID-0/1/10 support in software, via the

ServeRAID C100 for System x. This provides the advantages of RAID at no additional cost, although

without the performance boost of hardware RAID.

The serial design of the SATA bus allows maximum performance to be maintained as additional drives

are added.

Optional RAID controllers include:

• The 6Gbps (x8 PCIe) ServeRAID-M1015 SAS/SATA controller, which supports RAID-0/1/10 (no

cache) for up to 4 drives (system limit). The IBM ServeRAID M1000 Series Advance Feature Key

adds RAID-5/50 support.

• The 6Gbps (x8 PCIe) ServeRAID-M5014 SAS/SATA controller, which offers enhanced performance

with 256MB of cache memory, and supports RAID-0/1/10/5/6 for up to 4 drives (system limit).

High

Performance Adapter Slots

The x3100 M4 provides four PCIe Gen 2 adapter slots standard. PCI Express Gen 2 is the next

generation of high-performance, low-latency, serial I/O bus. Slot 1 is a x16 (“by 16”) physical / x8

Data transfer rates depend on many factors and are often less than the maximum possible.
