Consolidating multiple SQL Server systems onto

Dell PowerEdge R610 Servers using Microsoft’s Hyper-V

In our previous Guide, “Consolidating SQL Server databases from

Dell PowerEdge 2650 servers to a Dell PowerEdge 2950 server”

http://www.principledtechnologies.com/Clients/Reports/Dell/Consol

idating_2650_to_2950.pdf, we determined that, without

virtualization, we could successfully consolidate 10 identical

workloads onto a PowerEdge 2950 with a PowerVault MD1000

storage array. Each of these 10 workloads on the PowerEdge 2950

met or exceeded the performance of the single workload on the

PowerEdge 2650. Therefore, we use 10 as a reasonable

consolidation estimate in the example below.

In our example, we migrated our 10 physical SQL Server

environments to 10 virtualized SQL Server environments running

on a single server and allocated two virtual CPUs to each of the 10

virtualized environments. That is a total of 20 virtual CPUs, but our

new two-socket host machine has only eight cores, with two

hardware threads each. This usage is not a problem, however,

because Hyper-V handles the sharing of resources among the

virtual machines. In this example, because we have purchased the

Datacenter Edition of Windows Server 2008 and Enterprise Edition

of SQL Server 2008, we can create as many virtual environments

as we want.

NOTE: The cost analysis below shows only licensing savings

related to SQL Server. Windows Server 2008 licensing is

independent of SQL Server, so check with your Microsoft

sales representative about the complete costs of both

products.

Figures 2 and 3 present a brief cost analysis showing SQL Server

cost savings based on the configuration in Figure 1. The non-

consolidated environment assumes 10 Enterprise Edition SQL

Server instances, each running on a dedicated two-socket server,

and they use list prices. The virtualized environment assumes a

quad-core two-socket machine with each socket licensed for SQL

Server Enterprise Edition. Because Microsoft counts each socket as

a processor for licensing purposes, the virtualized environment

requires only one-fifth the numbers of licenses as the non-

consolidated environment, yielding considerable savings.
