Abstract
In one embodiment, a clustered storage system is configured to reduce parity overhead of Redundant Array of Independent Disks (RAID) groups, as well as to facilitate distribution and servicing of the storage containers among storage systems (nodes) of the cluster. The storage containers may be stored on one or more storage arrays of storage devices, such as solid state drives (SSDs), connected to the nodes of the cluster. The RAID groups may be formed from slices (i.e., portions) of storage spaces of the SSDs instead of the entire storage spaces of the SSDs. That is, each RAID group may be formed 'horizontally' across a set of SSDs as slices (i.e., one slice of storage space from each SSD in the set). Accordingly, a plurality of RAID groups may co-exist (i.e., be stacked) on the same set of SSDs.
