Assignee:

EMC Corporation - Hopkinton MA

International Classification:

G06F 3/00

US Classification:

710 45, 710 40

Abstract:

A scheduling method and apparatus for use by a processor that controls storage devices of a data storage system is presented. The method allocates processing time between I/O operations and background operations for predetermined time slots based on an indicator of processor workload.

International Classification:

G06F 13/16

US Classification:

710316, 710 38, 710305

Abstract:

Systems and methods are provided for executing a vendor specific command in a storage area network including a plurality of data storage volumes and at least one host. In one embodiment, a system includes an intelligent multi-protocol switch (IMPS) and a storage and switch controller that is coupled to the IMPS. The IMPS receives a command from the at least one host. The command includes a command byte field storing a vendor specific service action. The storage and switch controller receives the command from the IMPS. A processor included in the storage and switch controller interprets the vendor specific service action and executes the command.

International Classification:

G06F 1200
G06F 1300

US Classification:

395405

Abstract:

An expandable memory system and a method for operating a memory system having a variable number of memory banks are described. The memory system can utilize a variable number of separately replaceable memory banks which can be implemented with memory element, such as dynamic random access memory chips, which are of differing speeds and or sizes. The memory system implements an interleaving of memory addresses among the memory banks as a function of the number of banks actually present so that successive memory accesses are not unnecessarily delayed by the recovery times of the memory elements. The memory system includes a programmable address decoder having a writable memory which provides bank address signals. Each of the banks includes a respective delay line for providing an output signal a respective presettable time after address signals are received by that bank for signalling to the host that data is ready to be transferred.

Abstract:

Data storage federation equipment manages data storage arrays on behalf of host computers. In particular, the data storage federation equipment provides media type queries to the data storage arrays, each media type query requesting media type identification for a particular logical unit of storage (LUN) on a particular data storage array. The data storage federation equipment further receives, in response to the media type queries, media type responses from the data storage arrays, each media type response identifying media type for a particular LUN on a particular data storage array. The data storage federation equipment further performs, based on the media type responses, memory management operations that adjust operation of LUNs on the data storage arrays on behalf of the host computers. The memory management operations are performed while the data storage federation equipment remains interconnected between the host computers and the data storage arrays.
