Abstract

A management information transfer system is disclosed for use in connection with a network including one or more host computers and a mass storage subsystem interconnected by a plurality of switching nodes, the management information transfer system being configured to transfer processed management information to a management service center located remotely from the network. The management information transfer system includes a management server that is configured to receive management information from the switching nodes, and possibly the host computers, which may be directed to failures or other malfunctions in connection with their operations. The management server is configured to perform a filtering operation in connection with the management information that it receives from the switching nodes using filtering policies that may be established by, for example, a network administrator. The management server enables the mass storage subsystem to, in turn, enable its console to transfer the filtered management information to the management service center to facilitate diagnosis and possible correction of the failures or other malfunctions.

Claims

1. A management information transfer system for use in a connection with a network including a mass storage subsystem having a console and at least one switching node, the management information transfer system being for transferring processed management information to a management service center located remotely from the network, the system comprising:

A. a management server that receives management information from said at least one switching node that is directed to at least one failure or other malfunction related to the operation of the at least one switching node, and performs a filtering operation in connection with the management information in accordance with filtering policies that define criteria for which the management server will provide to the management service center;

B. wherein, the management server transfers the filtered management information to the management service center to facilitate diagnosis and possible correction of the at least one failure or other malfunction related to the operation of the at least one switching node in accordance with the filtering polices; and

C. an information transfer subsystem that receives the filtered management information from said management server by communicating with the mass storage subsystem over a switching fabric or selectively over a private link whereby the management service center takes corrective action, and thereby enabling the mass storage system to be remotely located from the management service center when it provides the corrective action.

2. A management information transfer system as defined in claim 1 in which said filtered management information to the management service center is transferred over the public telephony system.

3. A management information system as defined in claim 1 in which the mass storage subsystem receives the filtered management from the management server over the network.

4. A management information system as defined in claim 1 in which the mass storage subsystem receives the filtered management information from the management server over a connection separate from said network.

5. A management information transfer system as defined in claim 1 in which said management server polls said at least one switching node to retrieve said management information therefrom.

6. A management information transfer system as defined in claim 5 in which said management server polls said at least one switching node over the network.

7. A management information transfer system as defined in claim 1 in which said management server receives said management information in connection with an SNMP trap.

8. A management information transfer system as defined in claim 7 in which said management server receives said management information over the network.
