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

Key Features	High-Performance Processors
	The x3100 M3 supports one high-performance Intel Xeon, Core i3, Pentium, or Celeron
	processor, as the performance needs of your business dictate. The x3100 M3 offers a choice of
	processor clock rates, power draw, and cache sizes:
	• 95W quad-coreIntel Xeon models X3430 or X3450 at 2.4 or 2.66Ghz (respectively), with 64-
	bit extensions, 1333MHz memory access, 8MB of shared L3 processor cache, and low power
	draw (23.75W) per core
	• 73W dual-core Intel Core i3 model 540 at 3.06Ghz, with 64-bit extensions, 1333MHz memory
	access, 4MB of shared L3 processor cache, and reduced power draw (36.5W) per core
	• 73W dual-core Intel Pentium G6950 processor operating at 2.8GHz, with 64-bit extensions,
	1066MHz memory access, 3MB of shared L3 processor cache, and reduced power draw
	(36.5W) per core
	• 73W dual-core Intel Celeron G1101 processor operating at 2.26GHz, with 64-bit extensions,
	1066MHz memory access, 2MB of shared L3 processor cache, and reduced power draw
	(36.5W) per core
	The dual-core processors contain two complete processor cores; quad-core processors,
	similarly, contain four cores. The processors also contain one shared cache. The shared cache
	is dynamically allocated between cores as needed. The cores appear to software as physical
	processors. The two-core processors offer considerably higher performance than a same-speed
	processor with a single core. Likewise, four-core processors offer considerably higher
	performance than a same-speed processor with two cores.
	Intel Extended Memory 64 Technology (EM64T) 64-bit extensions allow the Xeon processor to
	use large memory addressing when running with a 64-bit operating system. This in turn lets
	individual software processes directly access more than 4GB of RAM, which was the limit of 32-
	bit addressing. This can result in much higher performance for certain kinds of programs, such as
	database management and CAD. Additional registers and instructions can further boost
	performance for applications written to use them. Contact your software providers to determine
	their software support for EM64T.
	1333MHz memory access offers up to 25% higher throughput at the same processor clock speed
	than 1066MHz memory access.
	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.

High-Performance, Low-Latency DDR3 ECC Memory

The x3100 M3 ships with one DIMMs installed and supports up to 16GB of unbuffered DIMM (UDIMM) memory in 4 DIMM sockets. It uses PC3-10600double data rate III (DDR3) memory (operating at 1066, or 1333MHz, depending on the processor type) for fast access, and provides ECC memory protection. (Notes: Non-ECC memory can be used as well, but reduces system availability. Mixing non-ECC and ECC memory in the same system is supported, but results in the server operating in non-ECC mode.)

The x3100 M3 supports either 1, 2, or 4 DIMMs. When 2 or 4 DIMMs are installed, memory operates in two-way interleaved mode for increased performance.

Memory is available in capacities of 1GB, 2GB, or 4GB DIMMs.

Drive Bays

The x3100 M3 contains six drive bays in total, including four 3.5-inchbays that support fixed SATA II drives and two 5.25-inch bays that support optical drive or tape drives. The HDD bays support slimline (1.0") drives, totaling up to 4TB per system, respectively.

A 5.25-inchbay contains a half-height DVD-ROMdrive, with a SATA interface, upgradeable to a

DVD-RWdrive. A second 5.25-inchbay 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.

Large HDD Storage Capacity

The x3100 M3 supports up to four 3.5-inchfixed SATA drives:

• 7,200 RPMs —250, 500, or 1TB (4TB maximum capacity)

Note: Enterprise-class 500GB+ SATA drives offer higher reliability and higher performance compared to lower-capacity SATA drives.
