5.8.4 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.
