Servers: Database consolidation on Dell PowerEdge R810 servers
29
Five benefits of the Dell PowerEdge R810 solution drive the cost
savings for this solution:
 Replaces up to 24 HP ProLiant DL385 servers and 12
HP StorageWorks MSA30 storage enclosures. The
increased capabilities of the Dell PowerEdge R810 solution
enable consolidation of multiple older systems for the
specific workload we tested.
 Fewer servers and storage arrays lower system
administration labor costs. There is significant savings
for this consolidation in labor costs for server and storage
administration. We estimate that the 24 older servers and
12 older storage arrays require 10 times more time to
administer than the new Dell PowerEdge R810 solution.
 Energy consumption is about one-seventh that of the
24 HP ProLiant DL385 solutions it replaces. The Dell
PowerEdge R810 solution provides considerable energy
savings over the older HP ProLiant DL385 solutions that it
replaces.
 Requires only one Windows Server and Windows SQL
Server license instead of 24 for the legacy solution.
Consolidation provides immediate savings for the
organization that maintains software assurance agreements.
We assume the enterprise maintains Microsoft Software
Assurance agreements for the Microsoft Windows Server
2003 version, and that it can transfer and upgrade one of
these for use on the new server. After the migration, the
enterprise will realize savings by not renewing the
remaining software agreements, which we assume are due
for renewal. We assume that the enterprise, which is
running SQL Server 2000 on the legacy servers, would not
maintain Software Assurance on a software version that old.
We therefore don’t include any ongoing SQL Server 2000
costs for the legacy solution. We include both per-server
license costs and Software Assurance costs for Windows
SQL Server 2008 R2 Enterprise edition on the new solution.
Even with that license cost, the enterprise saves on
software with the consolidated solution through the savings
in Software Assurance costs for retired licenses.
 Requires approximately one-tenth of the data center
rack space. Each server in both the legacy and
consolidated solutions requires 2u of rack space for the
server, and each storage array uses 3u of rack space. The
HP ProLiant DL385 solutions use a total of 84u, filling two
42u racks; the Dell PowerEdge R810 solution requires only
8u for one server and two storage arrays, filling less than a
fifth of a 42u rack.
