Disclosed herein is an apparatus and method for a distributed memory object system. In one embodiment, a method includes forming a system cluster comprising a plurality of nodes, wherein each node includes a memory, a processor and a network interface to send and receive messages and data, electing a cluster manager to mediates cluster membership, node identification assignment, and a name service group, creating a node manager to initiate services for each of the plurality of nodes, wherein the node manager is configured to notify the cluster manager of its existence and node health, and creating a plurality of sharable memory spaces, wherein each space is a distributed memory object having an object owner node, and partitioning address space within each sharable memory space into chunks, wherein data may be placed in one or more memory regions mapped to the distributed memory object by either of a store call or a write call, and data stored in one or more memory regions mapped to the direct memory object may be accessed by a load call or a read call.

Distributed memory object method and system enabling memory-speed data access in a distributed environment

The present invention is a method for performing a multi-protocol scan of a NAS system by a storage virtualization system to create a multi-protocol file index. Current NAS systems may utilize two protocols, CIFS and NFS. Storage virtualization systems migrate, redirect or synchronize data between a primary and a secondary NAS. Present storage virtualization systems are designed to work with NFS or CIFS systems, but not both. The present invention enables a storage virtualization system to simultaneously or near-simultaneously operate using NFS and CIFS protocols. The present invention also provides for a multi-protocol scan of a NAS device to ensure that all data files and data file attributes are recognized and preserved during storage virtualization.

Multi-protocol data object scanning by a storage virtualization system

Virtualizing a service is disclosed. A request to access a service from a first server is received from a client. A secret data associated with the first server is used to process the received request. The processed request is sent to a second server. The first and second servers are associated with a virtualization; and wherein the processed request can be used by the second server to authenticate the client.

The present invention is a system and method for reconciling results returned from a multi-protocol scan of a NAS system. Certain NAS systems use different protocols. Some may use the NFS protocol, whereas others may use the CIFS protocol. A scan of the NAS may therefore produce two data object names for a single data object. When a storage virtualization system is tasked with acting as an intermediary between the client and the NAS, these two data object names will cause errors during data migration, synchronization or redirection. The present invention is a method for using the results of a multi-protocol scan of the NAS in order to reconcile data object names that may present differently depending on the protocol applied.
