Abstract
A storage processing unit (SPU), which may be resident in a server in a storage system, provides a boot volume to the server and provides storage services. The SPU may execute a process including taking three snapshots of the boot volume respectively after writing an operating system image into the boot volume, after writing component images or otherwise customizing contents of the boot volume, and after the server boots from the boot volume. For updates, stability, or recovery of the storage system, the SPU may promote any of the snapshots to be the boot volume before the server reboots.
