Storage sizing recommendations
This topic provides guidelines for estimating data storage requirements for a BMC Server Automation installation.
Database sizing
Many factors influence the amount of storage consumed by the database that supports a BMC Server Automation installation. Factors of particular importance are:
- Number of managed servers
- Number and frequency of jobs run for each target
- Required retention period for historic job run data
For new installations for which no previous baseline data is available, BMC suggests a planning figure of 15 MB per managed server as a very general guideline for configuring the BMC Server Automation database server. However, you can use the following database sizing recommendations as starting points for your sizing exercise.
Environment size | CPU | RAM | Disk space | Number of Application Servers |
---|---|---|---|---|
Small (less than 5,000 to 10,000 managed targets) | 8 x 3.0 GHz+ 64-bit | 16 GB | 150 GB | 1 |
Medium (7,000 to 25,000 managed targets) | 16 x 3.0 GHz+ 64-bit | 24 GB | 900 GB | 2 |
Large (more than 25,000 managed targets) | 16-24 x 3.0 GHz+ 64-bit | 24 GB | 1 TB | 3 |
Note that the environment size depends on the number of managed targets, the use-cases you are implementing, and the expected job runtimes.
Note
Additional information on sizing is available in the "BMC BladeLogic Server Automation environment sizing and scalability" section in the BMC BladeLogic Automation Suite technical documentation.
Patch repository sizing
BMC Server Automation patch content, which is stored in patch repositories, varies in size depending on application and vendor. The following table presents patch storage requirements for various Microsoft applications, as observed in November 2011.
Patch download filter | Size |
---|---|
Microsoft Windows Server 2003 | 5 GB |
Microsoft Windows Server 2008 | 5 GB |
Microsoft SQL Server 2005 | 10 GB |
Microsoft SQL Server 2008 | 5 GB |
Microsoft Office 2007 | 8 GB |
Local storage requirements
Major patch deployments for Oracle Solaris and IBM AIX operating systems can require about 1 GB of local storage under /var/tmp on each host to be patched.
