9. Motherboard Specifications

At the heart of the ABERDEEN LLC AberNAS 120 / 126 lies a single processor motherboard designed to provide
maximum performance. Below are the main features of the ABERDEEN LLC AberNAS 120 / 126.
For further detailed documentation regarding the motherboard installed in this server please refer to the accompanying
NAS120-MOTHERBOARD.PDF found within the Aberdeen User's Manual CD-ROM.
9.1. Chipset
The ABERDEEN LLC AberNAS 120 / 126 is based on Intel's E7210 chipset. The E7210 chipset is made up of two
main components:
9.1.1. M C
EMORY ONTROLLER
The MCH controls the flow of data between the host (CPU) interface, the memory interface and the I/O
Controller Hub interface. It contains advanced power management logic and supports dual-channel
(interleaved) DDR memory, providing bandwidth of up to 6.4 GB/s using DDR2-400 SDRAM.
9.1.2. I/O C
ONTROLLER
The 6300ESB ICH provides the I/O subsystem with access to the rest of the system. It integrates a dual-channel
Ultra ATA/100 bus master IDE controller, two Serial ATA (SATA) host controllers, the SMBus 2.0 controller,
the LPC/Flash BIOS interface, the PCI-X (66MHz) 1.0 interface, the PCI 2.2 interface and the System
Management Controller.
9.2. Processors
The ABERDEEN LLC AberNAS 120 / 126 supports a single Intel® Pentium® 4 processor of up to 3.40 GHz with
hyper-threading technology in a 478-pin microPGA socket (must be 0.09 or 0.13 micron technology) or single a
Intel® Celeron® processor of up to 2.80 GHz.
• Hyper-Threading Technology provides thread-level-parallelism (TLP) on each processor resulting in
increased utilization of processor execution resources. As a result, resource utilization yields higher
processing throughput. Hyper-Threading Technology is a form of simultaneous multi-threading technology
(SMT) where multiple threads of software applications can be run simultaneously on one processor. This is
achieved by duplicating the architectural state on each processor, while sharing one set of processor
execution resources. Hyper-Threading Technology also delivers faster response times for multi-tasking
workload environments. By allowing the processor to use on-die resources that would otherwise have been
idle, Hyper-Threading Technology provides a performance boost on multi-threading and multi-tasking
operations for the Intel NetBurst® microarchitecture.
9.3. Memory
The ABERDEEN LLC AberNAS 120 / 126 has four (4) 184-pin DIMM sockets that can support up to 4 GB of ECC
or non-ECC unbuffered DDR400/333/266 SDRAM modules. (Memory operates in a dual-channel, or interleaved
configuration for increased performance.) Low-profile memory modules are required for use in the 1U form factor
of the ABERDEEN LLC AberNAS 120 / 126. Module sizes of 128 MB, 256 MB, 512 MB and 1 GB may be used to
populate the DIMM slots.
