    摘要： Methods, computer-readable media, and computer systems are provided for initiating storage of data on multiple storage devices and confirming storage of the data after the data has been stored on one but not necessarily all of the devices. A storage server receives, from a client, a request to store data. In response to the request, the storage server initiates, in parallel, storage of the data on multiple storage systems. The storage server detects that the data has been stored on any one of the storage systems, such as an auxiliary system, and, in response, indicates, to the client, that the data has been stored. The storage server may flush or discard data on the auxiliary storage system upon detecting that the data has been successfully stored on a target storage system, where the data persists.

    摘要： A host-based system for enhancing performance for a computing appliance has a central processing unit, an operating system, a long-term disk storage medium, and a persistent low latency memory (PLLM). Writes to disk storage at random addresses are first made to the PLLM, which also stores a memory map of the disk storage medium, and later made, in sequence, to the disk storage medium according to the memory map. In another aspect the host-based system is for continuous data protection and backup for a computing appliance, and has a central processing unit, an operating system, a long-term disk storage medium, and a persistent low latency memory (PLLM). In this aspect periodic system state snapshots are stored in the PLLM associated with sequence of writes to memory made between snapshots, enabling restoration of the host to any state of a prior snapshot stored in the PLLM, and then adjustment, via the record of writes to memory between snapshots, to any state desired between the snapshot states.
