There is provided a method for executing disk operations in a data storage system (DSS) including a power supply connected to a plurality of serially connected storage enclosures, and a power management module, where each storage enclosure includes at least one disk storage. Each logical partition of plurality of logical partitions is hosted on respective sets of disk storages corresponding to protection groups. The DSS causes activation of a set of protection groups, and authorizes a subset of protection groups to accept execution of disk operations. Disk operations are received and executed by the subset. In response to determining that an operation parameter of a given protection group of the subset is equal to a predetermined threshold, a remaining protection group of the set of protection groups is added to the subset, and a new protection group is activated and added to the set of protection groups.
