Meta Cache Distribution

This function displays the setting state of the automatic meta cache distribution and the location of the meta
cache.
"Meta cache" is a cache area in NAS for storing the management information of the file system. If the meta
cache distribution is different from the initial location when the NAS volumes (NAS user volumes and the NAS
backup volumes) are created, the meta cache is concentrated in one controller. In this case, the CM memory
where the meta cache exists may become insufficient or the access performance to the NAS volumes from the
CM without meta cache may be reduced.
This function is displayed in a Unified Storage environment.
To distribute the meta cache, using the [Initialize Meta Cache Distribution] function is recommended.
The meta cache distribution can be initialized manually. Refer to "Initialize Meta Cache Distribution" in
"ETERNUS Web GUI User's Guide (Settings)" for details.
The meta cache distribution can be initialized automatically. Refer to "Enable Automatic Meta Cache
Distribution" in "ETERNUS Web GUI User's Guide (Settings)" for details.
Automatic meta cache distribution can be disabled. Refer to "Disable Automatic Meta Cache Distribution"
in "ETERNUS Web GUI User's Guide (Settings)" for details.
