Appl. No.:

11/394943

Inventors:

Phillip Leef - Brookline MA, US
Douglas Sullivan - Hopkinton MA, US
Matthew Ferson - Worcester MA, US

Assignee:

EMC Corporation - Hopkinton MA

International Classification:

H04L 12/28
H04L 12/56

US Classification:

370254, 3703955

Abstract:

A data storage system includes storage array and a switch that is configurable to create numerous network topologies within the system and to maintain separate communications paths between different computerized devices or networks and the storage array. For example, a user device and a service device, such as a system diagnosis device, can connect to the storage array through the switch. In order to isolate interaction or communication between the user and service devices, the switch can be logically partitioned into two distinct switches to form two distinct, isolated communications paths between the devices and the storage array. With isolated communications pathways established in the switch, in use, the service device is unable to access the user device coupled to the storage array.

US Classification:

711114, 711111, 711112

Abstract:

Data storage system software is installed from nonvolatile memory. A storage processor is booted, transferring information stored in a nonvolatile memory module to a disk drive system, thereby enabling the system processor to boot directly from the disk drive system in subsequent boots. After the information is transferred the storage processor reboots using the information transferred to the disk drive system.
