Host port information is pulled directly from the switch before zoning is performed and is organized by chassis as an assist for mapping and masking an entire chassis. A graphical user interface allows a user to select storage by chassis to map and to select servers by chassis to map. The user then applies that mapping such that all servers selected are mapped to all storage selected. The user may repeat this mapping for another set of storage and servers. In a mixed environment, an icon may be shown in the graphical user interface to represent the mix. When the LUN mapping/masking is done, the LUN mapping/masking may be provided to the SAN manager to perform zoning. The LUN mapping/masking defines which host ports see which storage ports.

One method includes assigning a pointer from multiple logical blocks to the same original physical block if the multiple logical blocks include the same data. The method further includes receiving a command to write data to the first logical block and determining if the first logical block is a frequently accessed logical block. If the first logical block is a frequently accessed logical block, ownership of the original physical block is assigned to the first logical block. If ownership is established, the method includes copying any data stored in the original physical block to a new physical block, assigning a pointer from a second logical block to the new physical block, and performing the write command on the original physical block. A system includes a processor for performing the above method. One computer program product includes computer code for performing the method described above.

A high speed fabric is provided and is partitioned into sub-fabrics for host adapter traffic and device adapter traffic. A high-speed switch includes an expander for host adapter traffic and an expander for device adapter traffic. The high-speed switch also includes a plurality of connectors, where each connector is partitioned into dual interfaces. For each connector, one interface is connected to the host adapter traffic expander and the other interface is connected to the device adapter traffic expander. Blades are provided with one or more connectors, where each connector is partitioned into dual interfaces for host adapter traffic and device adapter traffic. The blades may be any combination of processor blades, boot drive enclosure blades, switched bunch of disks enclosure blades, and/or integrated RAID controller disk enclosure blades.

A method is disclosed to reconfigure a storage array. The method supplies a data storage and retrieval system comprising (N) data storage device assemblies, wherein each of those (N) data storage device assemblies comprises (M) data storage devices, wherein (N) is greater than or equal to 2, and wherein (M) is greater than or equal to 2. The method configures those (N) data storage device assemblies to comprise a spare data storage device assembly and a first storage array comprising the remaining (N−1) data storage device assemblies. In the event Applicants' method detects a failed data storage device disposed in the first storage array, then the method forms a second storage array comprising the first storage array, except the failed data storage device, in combination with a data storage device disposed in the spare data storage device assembly.

A method is disclosed to assign network addresses in a storage array disposed in a data storage and retrieval system comprising (P) data storage devices disposed in (N) data storage device assemblies. The method configures the (N) data storage device assemblies to comprise a spare data storage device assembly and a first storage array comprising (N−1) active data storage device assemblies, wherein each data storage device configured in the first storage array is assigned a network address, and wherein one of the spare data storage device disposed in the spare data storage device assembly is assigned a network address. In the event the method detects a failed data storage device disposed in the first storage array, then the method forms a second storage array comprising the first storage array, except the failed data storage device, in combination with the (i)th spare data storage device.

A blade server system includes a plurality of blade slots, a management module, and a plurality of switch modules. The switch modules provide connectivity to a plurality of communications fabrics. At least one switch module includes an integrated redundant array of independent disks (RAID) controller. A storage enclosure may be connected to the switch with the integrated RAID controller without having to include a stand-alone RAID controller, such as in one of the blade slots, and without having to include a RAID controller within the storage enclosure.

A method is disclosed to configure one or more storage arrays. The method supplies a data storage and retrieval system comprising (N) data storage device assemblies, wherein each of said (N) data storage device assemblies comprises (M) data storage devices, wherein (N) is greater than or equal to 2, and wherein (M) is greater than or equal to 2. The method configures a first storage array to comprise the (i)th data storage device disposed in two or more of said (N) data storage device assemblies, wherein (i) is greater than or equal to 1 and less than or equal to (M).
