A mirroring device includes an interface capable of coupling a primary storage array and a secondary storage array to a network. The interface further includes a logic that monitors traffic for a network packet destined for the primary storage array and selectively identifies a storage array write operation and associated data in the network packet, constructs a network packet targeted to the secondary storage array, and transmits the packet to the primary storage array and the secondary storage array.

Mirroring storage interface

Clamshell package

A database system is capable of executing a database application that transfers a logical object in multiple fragments. The database system comprises a main storage site, a remote storage site, a main protocol executable on the main storage site, and a remote protocol executable on the remote storage site. The remote storage site is capable of linking to the main storage site and mirroring information stored in the main storage site. The remote storage site includes a storage and a cache sidefile divided into a plurality of array sidefile recordsets. The main protocol is capable of including information indicative of logical object fragment commencement and completion in the multiple fragment database application transfer. The remote protocol is capable of controlling the cache sidefile to cache the multiple fragments as received and to enable destaging of the logical object to the storage on receipt of all fragments.

System for preserving logical object integrity within a remote mirror cache

A system and method for interconnecting electronic components for facilitating shared communication. The system comprises a translucent optical layer, a plurality of access slots in the translucent optical layer providing access thereto, and at least one electronic component having an optical communicator, and an optical interface connector. The optical interface connector is complementarily matched to at least one of the plurality of access slots. The optical communicator accesses the translucent optical layer when the at least one electronic component is inserted into at least one of the plurality of access slots.

Optical component connector

A virtual storage and computing device includes an array control processor, a virtual device blueprint and a transceiver. Shared and cache memory are linked to the array control processor. The array control processor uses a wireless link to request additional resources from at least one component selected from the group of disk controllers, disk drives, cache memory, shared memory and channel adapters to assemble a virtual device described by the virtual device blueprint. The shared memory and the cache memory have hardwired and/or wireless links to the array control processor. The array control processor receives the virtual device blueprint from a host computer that is linked to the array control processor using a channel adapter or via a wireless link between a host computer and the array control processor.
