Abstract: Examples are provided for a method of providing access to data of a data center. In one aspect, the method comprises storing a unit of data to each of a plurality of data nodes of a data center, designating a first node of the data center as a primary access node for the unit of data, the primary access node being configured to service access requests to the unit of data using one or more of the plurality of data nodes, determining that the first node is not available, and performing a failover process by reconfiguring a second node of the data center as the primary access node for the unit of data.

Abstract: Techniques are described in which storage nodes within a storage cluster are configured to support graph-based storage management. For example, a storage cluster comprises a network and a plurality of computing systems, each interconnected over the network, wherein the plurality of computing systems includes a plurality of storage nodes. The computing system of the plurality of computing systems is configured to allocate a volume of storage within the storage cluster, generate a volume graph of the volume, wherein the volume graph represents one or more functional elements in a data plane of the volume, and manage the volume based on the volume graph.

Abstract: Methods may include after a power loss, determining a most recently saved section of a logical block addressing (LBA) table, a previous section saved prior to the most recently saved section of the LBA table, and a least recently saved section of the LBA table, reading an open super block and updating entries in the LBA table from the most recently saved section through to the least recently saved section, reading a newest closed super block from a plurality of closed super blocks and updating entries in the LBA table from the previous section saved prior to the most recently saved section through to the least recently saved section, and reading an oldest super block and updating entries in the LBA table in the least recently saved section.
