Dell PowerEdge C6145 Rack Server Technical Guide
Function
An active sleep state
invoked when all
processor cores are idle
Lower memory voltage of
1.35V versus standard
voltage memory of 1.5V
Specialized ultra-low
power platforms are
great for cloud/dense
environments
Provides higher peak
throughput than earlier
memory technologies
Helps increase coherent
memory bandwidth and
reduce latency in
multi-node systems by
reducing cache probe
traffic between cores
Provides superior system
bandwidth between
processors and I/O,
increasing interconnect
rate from 2GT/s with HT1
in previous generations
up to a maximum
6.4GT/s with HT3
Choice of 4- or 6-core
processors, with each
core having its own L1
and L2 caches, and a
shared 6MB L3 cache
virtualization, which
provides direct control of
devices by a VM (enabled
by the
SR5690/SR5670/SR5650
chipsets)
AMD Extended Migration
allows you to safely
migrate a VM between
various AMD64 processor
revisions
Benefits
Delivers additional power savings (up to
10W for 2-processor servers) depending
on system configuration, such as when
the Northbridge and HyperTransport
technology links are powered down and
cores are at idle
Helps reduce overall memory power
consumption
Cooperative designs for specialized and
ultra-low power platform provide power
efficiency beyond just the processor
Enables improved overall system
performance and investment protection
compared to earlier technologies
Reduces the amount of cache probe bus
traffic, enhancing a server's efficiency
and scalability
Helps improves overall system balance
and scalability
Infrastructure designed to accommodate
either single- or dual-socket servers
providing server scalability from 4 cores
to 12 cores per server platform
Improved I/O performance within
a virtual machine
Enables an I/O device to be
directly assigned to a virtual
machine (VM)
Improved security through VM
address isolation
Provides unprecedented flexibility in
deploying, maintaining, and upgrading
servers in live migration environments
based on AMD64 processors
