Table 2-2 IBM Systems Director and CSM support for IBM AIX
Table 2-3 shows the firmware levels supported by both products.
Table 2-3 IBM Systems Director and CSM support for firmware
Both the Hardware Management Console (HMC) and the Integrated Virtualization Manager
(IVM) can be used by IBM Systems Director and CSM. Table 2-4 shows the version levels
supported.

requisites and performance recommendations for IBM Systems Director.

Note: IBM Systems Director recommends the use of the Common Agent on AIX clients. A
new AIX base system installation with current versions of AIX V5.3 or V6.1 will include the
Common Agent by default.

on system boot. See the VIOS documentation for details about starting the Common
Agent.
14 IBM CSM to IBM Systems Director Transformation Guide
IBM Systems Director Server for AIX requires installation on a supported IBM Power Systems
server running AIX, including IBM Power JS21 and later blade servers. The minimum
architecture is POWER5, but POWER7 is recommended for best performance. The hardware
resource requirements vary depending on the workload.
Server hardware requirements for running IBM Systems Director for AIX can be obtained by
using the IBM Systems Workload Estimator, which is a web tool for estimating hardware
requirements for various workloads. You can access the IBM Systems Workload Estimator
workload for IBM Systems Director at:
http://www-01.ibm.com/support/docview.wss?uid=nas7cd6a96f49d05f608862577420075c
a9a&aid=3.
The IBM Systems Workload Estimator asks several questions about your intended usage,
such as the number of systems you are managing and whether you are using a local or
remote database. After the questions are answered, IBM Systems Workload Estimator will
generate a drop-down list of system model and features that meet the resource requirements
of Systems Director including an estimate of the number of cores, memory, disk capacity, and
the number of disk drives required. It also shows a “Growth Solution” that can handle further
growth for managing larger environments.
When reviewing these recommendations, consider the following:
? Installation and startup times improve with faster disk access times. High-speed disk
adapters and faster drives provide the best performance.
? Disk sizes are arbitrary and indicative of disk requirements.
? System performance depends on the nature of your requirements and system workload.
? The IBM DB2® database software sizing should be comparable for Oracle.
? The Estimator only provides disk space requirements that are not on a file system base.
For AIX, consider that space requirements to run IBM Systems Director relate to the
following file systems:
– /opt - for server information not kept in a database unless using the default Derby
database. Refer to your database configuration for the file system hosting the
non-Derby database.
– /var - for Common Agent information and other log files.
? Paging space should be at least 3 GB regardless of the memory size.
? Using a logical partition in a larger server than displayed is also an option.
It might be necessary to change the maximum Java heap size in order for IBM Systems
Director to take advantage of additional memory. On AIX, the Java heap size setting is the
following path: /opt/ibm/director/lwi/conf/overrides/director.javaopt. On 64-bit
operating systems, the optimal heap size value is typically in the range of 2 GB (-Xmx2g) to
8 GB (-Xmx8g), depending on the systems being managed and the amount of physical
memory available on the IBM Systems Director Server.
Table 2-5 on page 15 provides information about disk storage requirements for installing IBM
Systems Director Server. These requirements include Common Agent and Platform Agent,
which are installed with IBM Systems Director Server. These requirements do not include disk
storage requirements for running IBM Systems Director Server and the database, updating
IBM Systems Director Server or for downloading and staging updates (such as AIX, HMC, or
system firmware updates) with Update Manager.
