System and method for accessing a storage area network as network attached storage
First Claim
1. A method for interfacing a storage area network (SAN) with a first data communication network, wherein one or more hosts coupled to the first data communication network can access data stored in one or more of a plurality of storage devices in the SAN, wherein the one or more hosts access one or more of the plurality of storage devices as network attached storage (NAS), comprising the steps of:
- coupling a SAN server to a SAN;
coupling a NAS server to the SAN server through a second data communication network;
coupling the NAS server to the first data communication network;
allocating a portion of at least one of the plurality of storage devices from the SAN server to the NAS server;
configuring the allocated portion as NAS storage in the NAS server;
exporting the configured portion from the NAS server to be accessible to the one or more hosts coupled to the first data communication network.

Abstract
A method, system, and apparatus for accessing a plurality of storage devices in a storage area network (SAN) as network attached storage (NAS) in a data communication network is described. A SAN server includes a first interface and a second interface. The first interface is configured to be coupled to the SAN. The second interface is coupled to a first data communication network. A NAS server includes a third interface and a fourth interface. The third interface is configured to be coupled to a second data communication network. The fourth interface is coupled to the first data communication network. The SAN server allocates a first portion of the plurality of storage devices in the SAN to be accessible through the second interface to at least one first host coupled to the first data communication network. The SAN server allocates a second portion of the plurality of storage devices in the SAN to the NAS server. The NAS server configures access to the second portion of the plurality of storage devices to at least one second host coupled to the second data communication network.

30. A storage appliance for accessing a plurality of storage devices in a storage area network (SAN) as network attached storage (NAS) in a data communication network, comprising:
-
a first SAN server configured to be coupled to the plurality of storage devices in the SAN via a first data communication network, wherein said first SAN server is configured to be coupled to a second data communication network;
a second SAN server configured to be coupled to the plurality of storage devices in the SAN via a third data communication network, wherein said second SAN server is configured to be coupled to a fourth data communication network;
a first NAS server configured to be coupled to a fifth data communication network, wherein said first NAS server is coupled to said second and said fourth data communication networks; and
a second NAS server configured to be coupled to said fifth data communication network, wherein said second NAS server is coupled to said second and said fourth data communication networks;
wherein said first SAN server allocates a first portion of the plurality of storage devices in the SAN to be accessible to at least one first host coupled to said second data communication network;
wherein said first SAN server allocates a second portion of the plurality of storage devices in the SAN to said first NAS server;
wherein said first NAS server configures access to said second portion of the plurality of storage devices to at least one second host coupled to said fifth data communication network;
wherein said second NAS server assumes the configuring of access to said second portion of the plurality of storage devices by said first NAS server during failure of said first NAS server; and
wherein said second SAN server assumes allocation of said second portion of the plurality of storage devices by said first SAN server during failure of said first SAN server. - View Dependent Claims (31, 32)
