Review the Assure MIMIX for AIX disk space and memory requirements:

  • Assure MIMIX for AIX requires 2 MB in root and 125 MB in /usr. The 125 MB in /usr is for the /usr/scrt directory which contains binaries, libraries, configuration, and logs.

Note: The /home/usr/scrt/ directory is created when the scrt user is created in AIX. Do not copy any files to this directory because Assure MIMIX for AIX deletes this directory during the de-installation process.

  • The amount of RAM required for the Assure MIMIX for AIX application depends on the size of the protected data (StateMap size) and log size. The maximum log size is one half of RAM.

  • The disk space requirement for Assure MIMIX for AIX file containers is approximately 500 MB for a small configuration.

  • For each Replication Group, allow approximately 200 MB in /var for log files.

  • The disk space requirement is approximately 70 MB for a small configuration and diagnostic logs.

  • Assure MIMIX for AIX requires at least 128 MB for logs on the production server, and at least 256 MB for logs on the recovery server for LFCs. The LFCs on the recovery server contain the undo and redo logs.

  • The calculation for the undo and redo logs is based on the required recovery window and the network outage protection size. Refer to Determining storage requirements. If you use the snapshot journal, ensure that you take into account its size. Refer to Guidelines for snapshot journal size.

  • The operating system and maintenance level must be correctly installed on all nodes. Each node should be at the same operating system version, and within two release levels of each other.

  • You should have at least 110MB of temporary disk space in /usr/sys for installation. The Cluster services will need an additional 86MB free space in /usr.
