Temporary space requirements vary from system to system. We recommend that at least 512 MB is available for the CA SDM installation purposes and 256 MB is available for the CA MDB installation. If the temporary space is less than the recommended minimum value, you can use the IATEMPDIR variable to redirect the temporary space of the installer to another folder.
(Advanced availability configuration) The following requirements must be met or exceeded for a CA SDM server to install and run properly:
|
Server Type |
CPU Requirements |
RAM Requirements |
Disk Space Requirements |
|---|---|---|---|
|
Standby or Background server Note: All standby servers and background server must have the similar hardware and software requirements. |
Minimum Dual Processor 2 GHz Preferred Quad Core Processor 2 GHz |
Minimum 4 GB Recommended 8 GB |
4 GB Note: The mentioned minimum disk space is for product installation and for minimal application log growth. |
|
Application server Note: The minimum recommended configuration for each of the application servers that the administration deploys must be the same. |
Minimum Dual Processor 2 GHz Preferred Quad Core Processor 2 GHz |
Minimum 4 GB Recommended 8 GB Note: The RAM size can be increased based upon the number of domsrvr or webengine pairs |
4 GB |
|
Remote MDB |
Minimum Dual Processor 2 GHz Preferred Quad Core Processor 2 GHz |
Minimum 4 GB Recommended 8 GB |
20 GB Note: The recommended minimum disk space is 20GB, but, you should also allow for incremental growth to accommodate both new MDB table entries and to provide enough space for additional Service Desk-related documents. |
|
Attachments Note: It is not recommended to have the attachment repository location as part of the standby or background or application server to avoid any link breakup during failover. It is recommended to keep it on an independent file server, preferably on a shared storage location, For advanced availability configuration, you may use SAN with RAID 5 configured. Best performance is achieved by using multiple repositories on multiple application servers. |
