Abstract

A backup appliance that can be disposed on a computer adapter card mid-plane internal to a data storage system. The appliance includes logic on the computer adapter card. The logic is configured for selectively allowing either directly controlling the robot picker through the fiber channel connection or indirectly controlling the robot picker by communicating with the backup server. The logic is also configured for controlling buffering of data stored in the data storage system and communicating directly with media backup drives for writing the data from buffers in the data storage system onto the backup media drives.

Claims

1. In a data storage environment including a backup server and a robot picker for servicing backup media, a backup appliance for backup of data stored on a data storage system to backup media, the backup appliance comprising:

a computer adapter card disposed on a mid-plane internal to the data storage system and including logic on the computer adapter card configured for (i) selectively allowing either directly controlling the robot picker through the fibre channel connection or indirectly controlling the robot picker by communicating with the backup server (ii) controlling buffering of data stored in the data storage system and (iii) communicating directly with media backup drives for writing the data from buffers in the data storage system onto the backup media drives.

2. The appliance of claim 1, wherein the selectivity is achieved by using a switch in cooperation with the connection.

3. The appliance of claim 1, wherein the connection is a fibre channel connection.

4. The appliance of claim 3, wherein the selectivity is achieved by using a switch in cooperation with the fiber channel connection.

5. In a data storage environment including a backup server and a robot picker for servicing backup media, a method of backing up data stored on a data storage system to backup media, the method comprising:

disposing a backup appliance on a mid-plane internal to the data storage system; and

including logic on the backup appliance that (i) selectively allows either directly controlling the robot picker through a connection or indirectly controlling the robot picker by communicating with the backup server (ii) controlling buffering of data stored in the data storage system and (iii) communicating directly with media backup drives for writing the data from buffers in the data storage system onto the backup media drives.

6. The method of claim 5, wherein the selectivity is achieved by using a switch in cooperation with the connection.

7. The method of claim 5, wherein the connection is a fibre channel connection.

8. The method of claim 7, wherein the selectivity is achieved by using a switch in cooperation with the fibre channel connection.
