Abstract:

Techniques are provided for a high availability solution (e.g., a network attached storage (NAS) solution) with address preservation during switchover. A first virtual machine is deployed into a first domain and a second virtual machine is deployed into a second domain of a computing environment. The first and second virtual machines are configured as a node pair for providing clients with access to data stored within an aggregate comprising one or more storage structures within shared storage of the computing environment. A load balancer is utilized to manage logical interfaces used by clients to access the virtual machines. During switchover, the load balancer preserves an IP address used to mount and access a data share of the aggregate used by a client.

Abstract:

Techniques are provided for load balancing for IP failover. A backend address of a first node is identified as a routing destination to which a request is to be routed by a load balancer based upon a load balancer rule mapping a frontend address, specified by the request as a request destination, to the backend address of the first node. The request is routed to a primary network interface of the first node using the backend address. The first node has a loopback interface with an address matching the frontend address for routing the request to a destination data structure based upon the request maintaining the frontend address as the request destination. Health probes are used by the load balancer for detecting a failure of the first node in order to failover to routing requests to a second backend address of a second node.

International Classification:

G06F 3/06

Abstract:

A clustered storage environment can distribute responsibility for naming virtual disks to nodes of the clustered storage environment. The clustered storage environment maintains a list of names in a structure that is visible to cluster member nodes responsible for naming the virtual disks. As the cluster member nodes discover mass storage devices (e.g., storage arrays) in the clustered storage environment, the nodes determine identifiers of the mass storage devices. For each mass storage device, the nodes use the mass storage device identifier to establish a namespace for virtual disks of the corresponding mass storage device. The nodes can then provide consistent, exclusive names for the virtual disks throughout the cluster that are manageable names.

International Classification:

G06F 17/30

Abstract:

A system and method for uniquely identifying a storage device among an array of storage devices of a storage system is provided. In some embodiments, a storage device of the storage system is identified. The storage device may currently lack a name or may have an invalid name. A shelf identifier of a storage device shelf in which the storage device is installed is determined. A stack identifier associated with a connection of the storage device is also determined. The storage system constructs a device name for the storage device based on the shelf identifier and the stack identifier. In some such embodiments, a bay in which the storage device is installed is determined, and the device name is further based on an identifier of the bay. The device name may include the stack identifier, the shelf identifier, and/or the identifier of the bay.
