International Classification:

G06F 12/00

US Classification:

711162, 707100, 707200, 707202, 711100

Abstract:

One aspect of the invention is a method for backing up data. An example of the method includes creating a description of a backup. The description of the backup may be created in response to receiving a request to perform a backup. This example also includes receiving a block of data to be backed up. This example further includes generating a packet that includes the block of data and metadata, wherein the block of data and the metadata are included in a common information protocol object. This example additionally includes transmitting the packet. This example may also include extracting the block of data from the packet, and storing the block of data on a storage device. If desired, this example may further include restoring the data block from the storage device.

Abstract:

Techniques are provided for on-demand resource allocation in a cluster having at least one initial virtual machine. It is determined that resource requirements have changed. At least one new virtual machine is created on at least one physical machine based on the changed resource requirements. The at least one new virtual machine is added to the initial cluster. Transactions for the at least one initial virtual machine are failed over to the at least one new virtual machine.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 15/16

US Classification:

709217, 709219

Abstract:

One aspect of the invention is a method for communicating in a computing system. An example of the method includes establishing a local communications interface at a local site. This example also includes writing local site communication information to the local communications interface, which comprises storing the local site communication information on a first site storage device at the local site, and sending the local site communication information from the first site storage device, to a third site storage device at a remote site, wherein the local site communication information is sent using a remote data replication protocol. The remote site communications interface may read the local site communication information from a third site storage device, and may send the local site communication information to a remote application at the remote site. Similarly, the remote application may send information to a local application at the local site.

Appl. No.:

12/030766

Inventors:

Mark James Seaman - San Jose CA, US
Lu Nguyen - Tampa FL, US
Prasenjit Sarkar - San Jose CA, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 12/00

US Classification:

711114, 711165

Abstract:

A mechanism to permit consolidation of storage subsystem volumes into larger, more easily managed volumes and an operating system device driver which includes a trap mechanism for intercepting calls from a host into logical unit devices that were previously consolidated into a single physical volume. A map converts such calls to a logical unit device into a corresponding offset in the single physical volume. A driver accesses the single physical volume with corresponding offsets to transfer data associated with a particular logical unit device. So, logical unit devices can be consolidated and reconsolidated to single physical volumes and other physical volumes without requiring changes to the operating system or its application software and without requiring application or host downtime.
