摘要:
A method is used for configuring I/O cache. A file system and a disk volume are identified. The file system is mounted on the disk volume. A cache mapper logical volume is created in response to a cache creation request. A cache volume is dynamically created from an existing cache storage unit, where the cache mapper logical volume is mounted on the disk volume and the cache volume.
摘要:
A method is used for managing cache backup and restore for continuous data replication and protection. I/O operations are quiesced at a cache module. A first snapshot of a storage object and a second snapshot of an SSD cache object are taken. The I/O operations at the cache module are unquiesced. A single backup image comprising the first snapshot and the second snapshot is created. The single backup image is sent to a first data protection appliance (DPA) and recorded in a journal.
