Appl. No.:

13/359203

Inventors:

Santosh Anath Rao - Santa Clara CA, US

Assignee:

NetApp, Inc. - Sunnyvale CA

International Classification:

G06F 15/16

US Classification:

709208

Abstract:

A storage area network (SAN)-attached storage system architecture is disclosed. The storage system provides strongly consistent distributed storage communication protocol semantics, such as SCSI target semantics. The system includes a mechanism for presenting a single distributed logical unit, comprising one or more logical sub-units, as a single logical unit of storage to a host system by associating each of the logical sub-units that make up the single distributed logical unit with a single host visible identifier that corresponds to the single distributed logical unit. The system further includes mechanisms to maintain consistent context information for each of the logical sub-units such that the logical sub-units are not visible to a host system as separate entities from the single distributed logical unit.

International Classification:

G06F 3/06
G06F 9/455

Abstract:

An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions to determine a frequency rate for tracking changed data of a virtual machine (VM), track the changed data at the determined frequency rate, receive a request to generate a recovery point associated with a specified time, and, responsive to receiving the request to generate the recovery point associated with the specified time, generate the recovery point.

Inventors:

- Sunnyvale CA, US
Vivek Venkatesan - Morrisville NC, US

Assignee:

NetApp, Inc. - Sunnyvale CA

International Classification:

G06F 9/455

US Classification:

718 1

Abstract:

A system and method of emulating a shared storage device includes determining a storage unit identifier (SUID) associated with a first local storage device in a first node of a distributed computing system, updating a first path handler to intercept storage requests including the SUID and being made on the first node and forwarding the storage requests to drivers for an emulated shared storage device, associating a second local storage device in a second node of the distributed computing system with the SUID, updating a second path handler to intercept storage requests including the SUID and being made on the second node and forwarding the storage requests to the drivers for the emulated shared storage device, and intercepting storage requests including the SUID and being made on the second node and forwarding the storage requests to the drivers for the emulated shared storage device.

Abstract:

Consistent distributed storage communication protocol semantics, such as SCSI target semantics, in a SAN-attached clustered storage system are disclosed. The system includes a mechanism for presenting a single distributed logical unit, comprising one or more logical sub-units, as a single logical unit of storage to a host system by associating each of the logical sub-units that make up the single distributed logical unit with a single host visible identifier that corresponds to the single distributed logical unit. The system further includes a mechanism to maintain consistent context information for each of the logical sub-units such that the logical sub-units are not visible to a host system as separate entities from the single distributed logical unit.
