Systems and methods for automated firmware update with rollback are described herein. The systems include a plurality of storage zones, each storage zone including a plurality of storage nodes, each storage node including a plurality of storage media. The method includes monitoring storage system activity and parameters and maintaining a data storage system usage and parameter database containing system activity information. When a firmware update is available, data storage system activity is evaluated. Storage nodes needing the firmware update are identified. The firmware update is run on available storage nodes identified as needing the firmware update. The impact of the firmware update is evaluated and a rollback of the firmware update is initiated on all firmware updated storage nodes when parameter variations are significant and/or result in degraded performance. |
