Abstract: A fast mount cache is provided by any offline storage media for fast volume mount access. The fast mount cache may be used as the first level in a hierarchical storage configuration after the high performance tier for data having high access rates shortly after creation but decreases sharply as the data ages. The fast mount cache stores migrated data from online hard disk drive storage and maintains the data on a volume basis as opposed to a file basis. As the fast mount cache capacity fills, or other events occur triggering a volume change, the fast mount cache erases the volume having the oldest data. While data is maintained on the fast mount cache for periods of time soon after it is migrated, the data may be accessed quickly. After the initial period of time has expired, the data only exists on tape storage or low tier data.

Abstract translation: 任何脱机存储介质都提供快速安装缓存，以实现快速卷安装访问。 快速安装缓存可以用作分层存储配置中的第一级，在高性能层之后，数据在创建后不久具有高访问速率，但随着数据的老化而急剧下降。 快速安装缓存存储从在线硬盘驱动器存储的迁移数据，并以数据为基础维护数据，而不是基于文件。 随着快速安装缓存容量的填满，或其他事件触发卷更改，快速安装缓存会擦除具有最早数据的卷。 虽然数据在迁移后很快就会在快速安装缓存上维护一段时间，但数据可能会被快速访问。 在初始时间段到期后，数据仅存在于磁带存储或低层数据上。
