International Classification:

G06F013/00

US Classification:

710/019000, 710/302000

Abstract:

The present invention is a method and system for allowing hot insertion and removal of removable storage devices of a storage system removing the requirement of a power shut-down of the storage system when a removable storage device fails. An insertion/removal event may be detected and an interrupt request line corresponding to an associated adapter of the affected drive may be enabled to alert a controller of the storage system of the insertion/removal event. Receipt of the interrupt request may provide notification of the insertion/removal event and may provide isolation to the affected drive such that the rest of the associated storage system may remain operational.

Abstract:

A client device may send a first request and then receive, in response to sending the first request, a first response and a first fingerprint tree corresponding to the first response. Next, the client device may cache the first response and the first fingerprint tree corresponding to the first response. Then the client device may send a second request and the first fingerprint tree and then receive, in response to sending the second request and the first fingerprint tree, a final second response and a final second fingerprint tree. The final second fingerprint tree may comprise a difference between the first fingerprint tree and an initial second fingerprint tree and the final second response may comprise a difference between the first response and an initial second response. The client device may update the cached first response with the final second response and the cached first fingerprint tree with the final second fingerprint tree.
