HP ProLiant Intel-based 100-series G6 servers
(Xeon 5670 compared to Xeon 5570). Compared to the 5500 Series processor, the 5600 Series
offers a smaller processor core size, new microcode instructions to accelerate encryption and
decryption algorithms, and new hardware features to improve power management capabilities.
The Xeon 5600 Series processor shown in Figure 3 offers 4- and 6-core processor models with a
shared cache of up to 12 MB. In addition to Intel QuickPath Interconnect and Hyper-Threading
technologies, the 5600 provides more efficient Turbo Boost and memory power management,
improved Intelligent Power Technology (Integrated Power Gates and Automated Low Power States)
with six cores, and Low-voltage DDR3 support.

Advanced Encryption Standard New Instructions
Advanced Encryption Standard New Instructions (AES-NI) is a set of six new instructions in the Intel
5600 Series processor architecture that is designed to consolidate the AES mathematical operations
and improve encryption performance. For applications using the AES algorithm, AES-NI speeds up
the encryption algorithms up to tenfold. This allows IT departments to deploy data encryption not
previously feasible due to performance concerns. Examples include AES-NI optimized SSL and IPsec
for protecting data in transit, and full-disk encryption or database encryption to protect data at rest.
Intel Xeon 3400 Series processor technology
The Intel Xeon 3400 Series are four core processors used with the Intel 5 series 3400 and 3420
chipsets. The Intel Xeon 3400 series Nehalem microarchitecture is based on 45 nanometer core
technology with an integrated memory controller and PCI Express graphics interface. Xeon 3400
series processors are used in the ProLiant ML110 and DL120 G6 servers.
The Xeon 3400 Series processors and chipsets can accommodate up to three DIMMs per channel
with registered DIMMs and up to two DIMMs per channel with unbuffered DIMMs. Figure 4 depicts
the ML110 and DL120 G6 architecture used with the Intel 3400 chipset.
