Abstract
Described are techniques for booting a data storage system. A first set of configuration and state information is read from first storage devices of a first RAID group using special processing code and a RAID library. A first set of system objects (of a system object topology) are instantiated using the first set of information. The first set of system objects represent storage entities containing a second set of configuration and state information. Using an I/O runtime stack based on the system object topology, the second set of information is read from second storage devices of a second RAID group using the same RAID library having calls made from method(s) of a RAID group object representing the second RAID group. A second set of client objects, instantiated using the second set of information, represent storage entities including client data stored on third storage devices of a third RAID group.
