Techniques for migrating active I/O connections with migrating servers and clients
First Claim
1. A computer program product, comprising:
- a computer-readable storage device; and
computer-readable code embodied on the computer-readable storage device, wherein the computer-readable code, when executed by a client, causes the client to;
determine when at least partial storage access control for the client is to be migrated from a first virtualized I/O server to a second virtualized I/O server;
select an I/O connection type from among multiple available I/O connection types available between the client and the second virtualized I/O server when the at least partial storage access control for the client is to be migrated; and
communicate the selected I/O connection type to the second virtualized I/O server, wherein the second virtualized I/O server is configured to facilitate storage access for the client using the selected I/O connection type.

Abstract
A technique for modifying an input/output (I/O) connection type between a client and a server includes determining, by the client, when at least partial storage access control for the client is to be migrated from a first virtualized I/O server to a second virtualized I/O server. An I/O connection type, from among multiple available I/O connection types available between the client and the second virtualized I/O server, is then selected by the client when the at least partial storage access control for the client is to be migrated. The selected I/O connection type is then communicated, by the client, to the second virtualized I/O server, which is configured to facilitate storage access for the client using the selected I/O connection type.

8. A data processing system, comprising:
-
a first virtualized I/O server configured to facilitate storage access control; a client configured to select an I/O connection type, from among multiple available I/O connection types, when at least partial storage access control for the client is migrated from the first virtualized I/O server; and a second virtualized I/O server configured to transmit the multiple available I/O connection types to the client in response to a query from the client, wherein the second virtualized I/O server is further configured to facilitate storage access control for the client during and following migration of the at least partial storage access control from the first virtualized I/O server to the second virtualized I/O server. - View Dependent Claims (9, 10, 11, 12, 13, 14)
