Abstract: A storage area network (SAN)-attached storage system architecture is disclosed. The storage system provides strongly consistent distributed storage communication protocol semantics, such as SCSI target semantics. The system includes a mechanism for presenting a single distributed logical unit, comprising one or more logical sub-units, as a single logical unit of storage to a host system by associating each of the logical sub-units that make up the single distributed logical unit with a single host visible identifier that corresponds to the single distributed logical unit. The system further includes mechanisms to maintain consistent context information for each of the logical sub-units such that the logical sub-units are not visible to a host system as separate entities from the single distributed logical unit.

Abstract: Techniques to managing non-disruptive SAN availability in a partitioned cluster comprising one or more components configured to determine whether to separate a cluster into two or more partitions, notify one or more responsive cluster nodes to separate the cluster into a first partition and a second partition, update one or more access states, notify the host that access states of one or more network paths has been updated, and provide the one or more access states. Other embodiments are described and claimed.
