Abstract: A method for power management of a storage system unit, the method may include selecting a power reduction measure out of (a) a shutdown of at least one stateless compute node out of stateless compute nodes of the storage system unit, and (b) an other power reduction measure that does not involve the shutdown of the at least one stateless compute node, while prioritizing the shutdown of the at least one stateless compute node over the other power reduction measure; wherein the storage system unit further comprises storage nodes; wherein states related to communications with client computers (i) are maintained in the storage nodes, and (ii) are not stored on the stateless compute nodes; and applying the power reduction measure based on the selecting.

Abstract: A storage system is provided. The storage system includes a backplane; a plurality of single port storage devices; and a plurality of controllers, wherein the backplane routes a plurality of interconnection lanes between the plurality of controllers and the plurality of single port storage devices, wherein the plurality of controllers is configured to: enable at least one second interconnection lane of the plurality of interconnection lanes when a first controller of the plurality of controllers has failed, wherein a first interconnection lane of the plurality of interconnection lanes is between the first controller and a first single port storage device of the plurality of single port storage devices, wherein the at least one second interconnection lane is between a second controller of the plurality of controllers and the first single port storage device.

Abstract: A distributed storage system. The distributed storage system includes a plurality of storage nodes (DNodes), wherein the DNodes are configured to store a plurality of elements and a plurality of data blocks, wherein each element is a persistent metadata structure, wherein at least one of the elements store at least one attribute, wherein the at least one attribute includes a plurality of pointers; and a plurality of compute nodes (CNodes), wherein each CNode has access to each of the DNodes, wherein each CNode is assigned to a respective at least one cluster of a plurality of clusters, wherein each CNode is configured to receive at least a portion of access commands directed to the respective at least one cluster and to execute the received access commands based on the plurality of elements.
