Consolidating multiple SQL Server systems onto
Dell PowerEdge R610 Servers using Microsoft’s Hyper-V
10
• More processing power per core. While clock speeds
have not changed dramatically, processors have undergone
a generational shift. Industry-standard benchmarks, such as
SPECint, show today’s processors are much faster than their
counterparts of three to five years ago.
• 64-bit address space. Five years ago, many processors
did not support 64-bit addressing. Windows Server 2003 did
not support 64-bit addressing on x64 processors until 2005.
• Faster memory. The memory in a modern system may be
as much as two to three times as fast as that in a three- to
five-year-old system.
• Faster storage. The performance of storage subsystems
has continued to improve.
• Cheaper storage and greater capacity. Disk capacity has
greatly increased, while the cost per GB has decreased.
Moreover, external storage arrays radically increase the
amount of storage available to a server.
The PowerEdge R610 we use in this Guide demonstrates many of
these capabilities. It has two Nehalem-based Quad-Core E5520
Intel Xeon processors and can hold up to 96 GB of RAM. Intel’s
QuickPath Technology provides fast access to this increased
memory. Dell has optimized the PowerEdge to reduce both power
consumption and heat. Finally, the two EqualLogic PS5000 arrays
can give the PowerEdge access to over 2 TB of storage, far in
excess of what would have typically been available in a server of
this class just a few years ago.
We further discuss sizing at a conceptual level in the Getting ready
section of this Guide.
Hyper-V overview
Microsoft includes its hypervisor, Hyper-V, in certain editions of
Windows Server 2008. Generally speaking, a hypervisor is a Type
1 virtualization product: a thin layer of software enabling virtual
machines to run on one physical machine and allowing direct
access to most hardware.
Requirements for running Hyper-V
The PowerEdge R610 meets the requirements of Hyper-V, which
include the following:
• A supported processor, such as the Intel
®
64-based Xeon
E5520 processor
• A 64-bit Windows Server 2008 version (Standard,
Enterprise, or Datacenter)
• Hardware Data Execution Protection (DEP) enabled
