TECHNIQUES FOR SAN STORAGE CLUSTER SYNCHRONOUS DISASTER RECOVERY

摘要

Improved techniques for disaster recovery of storage service accessible through storage area networks are disclosed. Embodiments include establishing peer relationships between nodes of primary and secondary computing clusters. Configuration information is replicated in near synchronous manner from a primary cluster and used to configure a secondary cluster in a similar manner. Host data is replicated in synchronous manner for all the storage devices and LUNs within them. The secondary cluster is kept updated continuously with configuration information and user data in LUNs on storage devices such that a host may be served data from the secondary cluster when the primary cluster experiences a disaster or failure. Other embodiments are described and claimed.

1. A computer-implemented method, comprising:
creating, by processor circuitry, a relationship between a primary cluster and a secondary cluster of a storage area network; establishing, by the processor circuitry, a peer relationship between one or more nodes of the primary cluster and one or more corresponding nodes of the secondary cluster; collecting, by the processor circuitry, configuration information from one or more nodes of the primary cluster; transferring, by the processor circuitry the collected configuration information to one or more nodes of the secondary cluster; and configuring, by the processor circuitry, one or more nodes of the secondary cluster based upon the transferred configuration information.
