DELL POWEREDGE M820 BLADE SERVER SOLUTION: SOFTWARE
COST ADVANTAGES WITH ORACLE DATABASE 11g R2
Upgrading a data center requires more than just selecting new equipment –
considerations range from performance to energy, and of course, software licensing
costs. How do you select a solution that maximizes your capital when it comes to a
significant recurring cost such as licensing costs? Many enterprise applications base
licenses on the server core count, which means that choosing high-performing servers
that do more with fewer cores can save your organization significant money.
We examined the licensing-cost implications of selecting a Dell PowerEdge
M820 blade server solution to replace a previous-generation HP ProLiant BL680c G7
blade server solution, specifically when running Oracle Database 11g R2. Over three
years, the 32-core Dell PowerEdge M820 solution could save up to $315,400 in Oracle
Database licensing in a server-versus-server scenario as compared to the 40-core HP
ProLiant BL680c G7 solution when using Oracle Database 11g R2.
In addition to maximizing licensing cost savings, you want to ensure that a
potential upgrade will maintain, or even exceed, the performance capabilities of your
prior hardware. Principled Technologies tested the PowerEdge M820 with a latest
generation storage Dell Compellent SC8000 SAN solution, and found that it provided

much better performance than a previous-generation HP ProLiant BL680c G7 server and
HP EVA StorageWorks solution.
Licensing costs for high-end enterprise applications can make all the difference
to your data center’s bottom line. Choose a more powerful server with fewer cores and
watch the licensing savings roll in, leaving your staff more time to innovate and freeing
up capital to improve infrastructure.
LOWER LICENSING COSTS WITH THE DELL POWEREDGE M820
By running software with core-based pricing on a 32-core Dell PowerEdge M820
server with Intel Xeon processors E5-4650 rather than on a server with a higher core
count, an organization can save significantly on license costs.
We compared the Oracle Database 11g R2 Enterprise Edition licensing costs for
a 32-core Dell PowerEdge M820 server to the costs to license a 40-core HP ProLiant
BL680c G7. We found that a single 32-core Dell PowerEdge M820 server can save up to
$315,400 in three-year costs for Oracle Database 11g R2 Enterprise Edition per-core
licenses and Software Update License and Support compared to a single 40-core
previous-generation server, while delivering superior performance.

With 20 percent fewer cores than a 40-core server, the 32-core Dell
PowerEdge M820 can save 20 percent on costs for software licensed on percore basis.

In our testing for this report, we ran Oracle Database 11g R2 Enterprise
Edition, which can use either Processor or by Named User Plus licensing. We
calculate prices for Processor licensing, the type of licensing that an
enterprise would select if it had third-party users or a large number of
internal users. The number of required processor licenses is based on core
count, with each license supporting two x86 cores. Compared to the 40-core
HP ProLiant BL680c G7 server that we tested, a fully licensed Dell
PowerEdge M820 server requires four fewer Oracle Database 11g R2
Enterprise Edition processor licenses, saving $315,400 for licenses and three
years of Software Update License and Support (SaS) protection.1
Your organization could potentially increase core-based software license savings
by consolidating the workloads of older, higher-core servers onto the 32-core Dell
PowerEdge M820 server. To simulate a consolidation scenario, Principled Technologies
tested the Dell PowerEdge M820 server with Dell Compellent storage and the previousgeneration HP ProLiant BL680c G7 server with the previous-generation HP EVA4400

We used prices for the Oracle Database Enterprise Edition Processor License and Software License and Support (SaS) from the Oracle Technology
Global Price list on the Oracle site: http://www.oracle.com/us/corporate/pricing/technology-price-list-070617.pdf dated July 19, 2012. The Oracle
Processor Core Factor Table last updated July 19,2012 shows Intel E5-series and E7-series processors with a Core Processor Licensing Factor of 0.5.

storage. In both cases, we ran an OLTP workload using Oracle Database 11g R2. In this
simulated upgrade and consolidation scenario, we achieved a performance
improvement of 195.4 percent when using the Dell PowerEdge M820 with the Dell
Compellent SC8000 SAN. Because each hardware configuration will vary in an upgrade
situation, consolidation amounts will also vary.
The database performance improvement of 195.4 percent that the Dell
PowerEdge M820 server with Dell Compellent SC8000 storage provided over the HP
ProLiant BL680c G7 server with HP EVA 4400 storage means that a single PowerEdge
M820 solution delivered the performance of 2.95 HP ProLiant BL680c G7 solutions in
our tests.
To avoid having to calculate software costs for partial servers, we round 2.95 to
3, and compare costs for one Dell PowerEdge M820 solutions versus three HP ProLiant
BL680c G7 solutions. A Dell PowerEdge M820 server with Dell Compellent SC8000
storage could provide similar performance and save as much as $3,469,400 in Oracle
Database 11g R2 Enterprise Edition processor licenses and three-year SaS costs
compared to three HP ProLiant BL680c G7 servers with HP EVA 4400 storage.

Compared to three 40-core servers, a 32-core Dell PowerEdge M820 server
can save over 73.3 percent in both license count and software costs for
software licensed on a per-core basis.

The 32-core Dell PowerEdge M820 server would require 16 Oracle Database
11g R2 Enterprise Edition processor licenses compared to 60 licenses for
three 40-core HP ProLiant BL680c G7 servers.

For Oracle Database 11g R2 Enterprise Edition licenses, savings for 44 fewer
processor licenses could reach $3,469,400 for the license and three years of
SaS protection.

With Dell Compellent storage, Dell aims to deliver resilient storage solutions
that increase business continuity by providing high availability. According to Dell,
Compellent storage brings flexibility to your data center by providing scalable adaptable
storage that can handle the growth of your business and adapt with new technologies.
The storage we used in our tests, the Dell Compellent SC8000 SAN, has the
capacity to support up to 960 SAS drives, and is compatible with SSD, SAS, and NL-SAS
drives. The array is also backwards compatible with existing Compellent Fibre Channel
and SATA drives, allowing for a mix of drive types in the same SAN. The Dell Compellent
SC8000 uses the power of two 2.5GHz Intel Sandy Bridge processors to power your
database workloads, and supports a combination of RAID levels for your data.
Dell Compellent Storage Area Networks are based on Dell Fluid Data
Architecture, which is intended to put the right data in the right place at the right time
to ensure responsive ad hoc queries and data analysis. Dell Compellent Storage Center
works with Oracle 11g Automatic Storage Management (ASM) to provide an applicationaware data protection capability. In addition, Compellent’s Data Progression and
Dynamic Capacity work with Oracle ASM to enable thin replication and automated
tiered storage.

Compellent Data Progression dynamically moves enterprise data to the optimal
tier based on actual use. For instance, the most active blocks will reside on highperformance SSDs, Fibre Channel drives, or SAS drives, while infrequently

accessed data migrates to lower-cost, high-capacity SAS drives. Dell Compellent
FastTrack places frequently accessed data on the outer sections of the disk to
improve performance even further.
Dell Compellent enables virtualized storage at the disk level, creating a dynamic
pool of shared storage resources available to multiple servers. With read/write
operations spread across all drives, multiple requests can be processed in
parallel, boosting system performance. Compellent allows for changes to RAID
levels and storage tiers on the fly, even while the volumes are in use.
Dell Compellent’s thin provisioning software, Dynamic Capacity, strives to
deliver higher storage utilization by eliminating pre-allocated but unused
capacity. Dynamic Capacity separates allocation from utilization, enabling users
to provision volumes upfront while only consuming disk space when data is
written.

WHAT WE TESTED
About DVD Store Version 2.1
To create our real-world ecommerce workload, we used the DVD Store Version
2.1 (DS2) benchmarking tool. DS2 models an online DVD store, where customers log in,
search for movies, and make purchases. DS2 reports these actions in orders per minute
(OPM) that the system could handle, to show what kind of performance you could
expect for your customers. The DS2 workload also performs other actions, such as
adding new customers, to exercise the wide range of database functions you would
need to run your ecommerce environment. For more information about the DS2 tool,

APPENDIX C – SOFTWARE LICENSING DETAILS
Savings details
Save 20% in software license counts and costs for software licensed on a purely per-core basis
The Oracle Technology Global Price List on the Oracle Web site prices the Oracle Database 11g R2 Enterprise
Edition license pack at $47,500 USD.2 Oracle Software Update License and Support, priced at 22 percent of the license
cost per year, adds $10,450 per year, or $31,450 over three years, and brings the three-year cost of each license to
$78,850. We use those prices and do not apply any quantity discounts in our analysis.
Figure 3 shows that with 20 percent fewer cores, the Dell PowerEdge M820 requires 20 percent fewer core
licenses than the HP ProLiant BL680c G7. License count is the number of cores times a multiplier found in the Oracle
Processor Core Factor table.3 The table shows a multiplier of 0.5 for both the E5-4650 processor type of the Dell
PowerEdge M820 and the E7-8867L processor type of the HP ProLiant BL680c G7, so the required number of Oracle
Database 11g R2 Enterprise Edition processor licenses equals half the core count of the server for a fully licensed server.

Depending on existing software license agreements, an enterprise migrating workloads from older servers to
newer Dell PowerEdge M820 servers might be able to transfer or upgrade existing licenses at no cost or at lower cost
than shown here. The organization could save on support costs proportionate to the lower license count of the newer
servers.
Our test results show the potential for consolidation and further software savings for the Dell PowerEdge M820
solution.
The single server license calculations in Figures 8 and 9 do not take into account the superior performance of the
Dell PowerEdge M820 server solution. In our tests, a Dell PowerEdge M820 server solution delivered 195.4 percent
better performance, or 2.95 times the performance of an HP ProLiant BL680c G7 server solution. Using that
performance result to calculate a consolidation factor, one Dell PowerEdge M820 solution could support the workload
nearly three HP ProLiant BL680c G7 solutions. The software savings for that consolidation factor would be
correspondingly higher than the one-to-one comparison in the previous figure. Rather than attempt to calculate license
counts for a fraction of an HP server, we, do a slight rounding, and calculate Oracle Database 11g R2 Enterprise Edition
license counts for one Dell PowerEdge M820 server vs. the three HP ProLiant BL680c G7 servers. Figure 5 shows the
consolidation calculations.

Figure 8: Our network setup for the HP ProLiant BL680c G7 server solution.
Our complete HP storage infrastructure consisted of two 10Gb Fiber Channel (FC) HBA ports connected to two
Virtual Connect 4Gb FC switches. These FC switches were then connected to two Brocade 200E FC switches, and then to
the two EVA 4400 storage controllers.
The EVA 4400 contained 58 15K RPM FC drives. We combined them into one 58 disk database and log disk
group. All LUNs were configured in RAID 10.
For volumes, we created the following:

Configuring the database (DVD Store)
Data generation overview
We generated the data using the Install.pl script included with DVD Store version 2.1 (DS2), providing the
parameters for our 1TB database size and the database platform on which we ran: Oracle Database 11g Release 2. We
ran the Install.pl script on a utility system running Linux. The database schema was also generated by the Install.pl script.
After processing the data generation, we transferred the data files and schema creation files to an Oracle Linuxbased system running Oracle Database 11g Release 2. We built the 1TB database in Oracle Database 11g Release 2, and
then performed a full backup, storing the backup file on a mapped LUN for quick access. We used that backup file to
restore on both servers between test runs. We performed this procedure once, and used the same backup file for all
Oracle Linux machines.
We made a few modifications to the schema creation. We created additional indexes to improve lookup
performance and reduce table scans. We configured the tablespaces to use ASM and created 16-24 files per tablespace
to improve parallelism and allow for potential database file expansion. Additionally, we modified the login stored
procedure to bypass using the temporary tablespace. Finally, we also modified the data generation scripts (see DVD
store modifications section below). Specifically, we followed the steps below:
1. We generated the data and created the database and file structure using database creation scripts in the DS2
download. We made size modifications specific to our 1TB database and the appropriate changes to drive
letters.
2. We transferred the files from our Linux data generation system to a Linux system running Oracle Database.
3. We created database tables, stored procedures, and objects using the provided DVD Store scripts.
Dell PowerEdge M820 blade server solution: Software cost advantages
with Oracle Database 11g R2
A Principled Technologies test report 20
4. We loaded the data we generated into the database using sqlldr and the provided DVD Store load scripts.
5. We created indices, full-text catalogs, primary keys, and foreign keys using our modified database-creation
scripts.
6. We updated statistics on each table according to database-creation scripts, which sample 20 percent of the
table data.
7. We created a database user, and mapped this user to the Oracle Database login.
8. We then performed a full backup of the database. This backup allowed us to restore the databases to a pristine
state relatively quickly between tests.
DVD Store modifications
We made a few modifications to the database creation scripts and the client driver source code for DVD store to
allow the benchmark to scale up to 1000GB. The files we modified and their changes are list below:
1. ds2_data.h
a. Increased the number of actor first and last names from 200 each to 500 each.
2. ds2_create_prod.c
a. Increased the random number selection range for actor names from 200 to 500.
3. ds2xdriver.cs
a. Increased the number of actor first and last names from 200 each to 500 each.
b. Increased the random number selection range for actor names from 200 to 500.
4. oracleds2_create_ind.sql
a. Created a new index on the CUST_HIST table that included the CUSTOMERID and PROD_ID columns.
b. Changed the PK_ORDERS index to a reverse index.
c. Created a new index on the ORDERS table that included the CUSTOMERID column.
d. Changed the PK_ORDERLINES index to a reverse index.
e. Created a new index on the PRODUCTS table that included the PROD_ID and COMMON_PROD_ID
columns.
f. Created a new index on the PRODUCTS table that included the SPECIAL, CATEGORY, and PROD_ID
columns.
g. Changed the IX_INV_PROD_ID index to a unique index and made it the primary key.
h. Created a new index on the REORDER table that included the PROD_ID column.
5. oracleds2_analyze_all.sql
a. Modified to include all new indexes.
b. The “estimate_percent” properties were changed from 18 to 20.
6. oracleds2_create_sp.sql
a. Removed the “derivedtable” global temporary table creation.
b. Modified the LOGIN procedure to not use the “derivedtable” global temporary table.
7. oracleds2_create_tablespaces_1000GB_asm.sql
a. Modified to use ASM datastore.
b. Used 24 datafiles for the CUSTTBS tablesplace.
c. Used 24 datafiles for the INDXTBS tablesplace.
d. Used 16 datafiles for the ORDERTBS tablesplace.
e. Used one BIGFILE datafile for the DS_MISC tablespace.
f. Modfied TEMP and UNDOTBS default global tablespaces to use a single BIGFILE datafile with unlimited
MAXSIZE.

Running the DVD Store tests
We created a series of batch files, SQL scripts, and shell scripts to automate the complete test cycle. DVD Store
outputs an orders-per-minute metric, which is a running average calculated through the test. In this report, we use the
last OPM reported by each client/target pair to calculate the advantage of the new solution. We downloaded the latest
Oracle Data Provider for .NET 2.x (version 2.112.3.0). We used eight client systems with 32 threads running on each for a
total 256 threads to generate a high load rate.
Each complete test cycle consisted of the general steps listed below. For each scenario, we ran three test cycles,
and chose the median outcome.

Clean up prior outputs from the host system and all client driver systems.
Drop all databases from the system under test (SUT).
Restore all databases on the SUT.
Reboot the SUT and all client systems.
Wait for a ping response from the SUT and all client systems.
Let the test server idle for one hour.
Start the DVD Store driver on all respective clients.
We used the following DVD Store parameters for testing the virtual machines in this study:
