  • Publication number: 20230409447
    Abstract: Improved techniques for disaster recover within storage area networks are disclosed. Embodiments include replicating a LIF of a primary cluster on a secondary cluster. LIF configuration information is extracted from the primary cluster. A peer node from a secondary cluster is located. One or more ports are located on the located peer node that match a connectivity of the LIF from the primary cluster. One or more ports are identified based upon one or more filtering criteria to generate a candidate port list. A port from the candidate port list is selected based at least upon a load of the port. Other embodiments are described and claimed.

  • Patent number: 10693955
    Abstract: 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.

  • Patent number: 7865587
    Abstract: A system and method are provided for reassigning port names to ports (e.g. Fibre Channel ports, etc.). This is accomplished by allowing for user involvement during the port name assignment process. By this feature, port names may be assigned and reassigned, as desired, without re-wiring cables or re-configuring storage network so that disruption to host traffic can be minimized. To this end, in various embodiments, the port names are capable of being maintained in a consistent manner after replacement of such hardware, by appropriately reassigning the port names, etc.
