摘要:
A primary group may be swapped with a synchronous backup group where triangular asynchronous replication is being provided between the primary group, the synchronous backup group and an asynchronous backup group. Swapping may include halting work at the primary group, transferring pending mirrored data from the primary group to an asynchronous backup group, creating a data mirroring relationship between a storage volume at the synchronous backup group and a storage volume at the asynchronous backup group, reversing a data mirroring relationship between the storage volume at the primary group and the storage volume at the synchronous backup group, and resuming work at the asynchronous backup group.

Handling failure of a primary group at a first data center that is part of plurality of data centers providing triangular asynchronous replication includes creating a data mirroring relationship between at least one storage volume at a second data center having a synchronous backup group that is part of the plurality of data centers and at least one storage volume at a third data center having an asynchronous backup group that is part of the plurality of data centers and resuming work at the third data center. Handling failure of a primary group at a first data center may also include synchronizing the at least one storage volume at the second data center with the at least one storage volume at the third data center prior to resuming work at the third data center.
摘要:
Storing recovery data includes a host processor writing data to a local storage device, the host processor causing the local storage device to accumulate chunks of data corresponding to writes by the host processor, where each chunk of data represents data written before a first time and after a second time and where the second time for one of the particular chunks of data corresponds to a first time for a subsequent one of the particular chunks of data, transmitting the chunks of data from the local storage device to a remote destination, providing synchronous data from the local storage device to a local destination; and, the host processor causing an indicator to be provided to the local destination in connection with creation of a new chunk of data for storage at the remote destination. The local destination may maintain a plurality of maps, where each of the maps associates synchronous data being provided thereto with a specific chunk of data. In response to receiving an indicator in connection with creation of a new chunk of data, the local destination may point to a new map. There may be two maps or more than two maps.

A casket assembly includes a container and a two-piece lid. The two-piece lid includes a superior lid that covers the anterior end of the casket and an inferior lid that covers the opposite end. The container includes a bottom panel, an inferior end panel, a superior end panel, and two elongated side panels. Each elongated side portion has a recessed portion on the superior end of the casket for providing an improved viewing of the deceased. In one embodiment, the casket panels each include a plurality of mortise holes and/or tenons. The tenons on individual panels are designed to fit into the mortise holes on other panels. Pins are placed through pinholes on the tenons to retain the tenons in the mortise holes. A shelf and bracket assembly may be provided for use in displaying mementos of the deceased and/or for supporting the inferior casket lid.

A rental casket system includes a casket with a recessed side panel for ease of viewing. The casket includes a removable end piece which is one embodiment is located within grooves formed in the side panels of the casket. The grooves widen near the upper portion of the side panels and are partially covered by a top panel. The rental casket system includes a tray assembly that may be used as part of a cremation casket. The tray has short side walls and may include an inner assembly that prevents contact with a deceased when handholds in the tray assembly are used to move the tray assembly. The tray and a lid form a burial bell assembly that may be sealed for burial. The tray assembly may include side walls that are movably attached to end walls. Lid segments are provided with the tray so that the tray may also be used as an identification tray.
