Systems and methods for providing service virtualization endpoint (SVE) redundancy in a two-node, active-standby form. An active-standby pair of SVEs register with a cloud-centric-network control point (CCN-CP) as a single service node (SN) using a virtual IP address for both a control-plane and a data-plane. At any given time, only the active SVE is a host for the control-plane and the data-plane. When a failover happens, the hosting operation is taken over by the standby SVE, therefore the failover will be transparent to CCN-CP and the SN.

Disclosed are methods and apparatus for facilitating transmission of file access type messages over a Fiber Channel (FC) network. In one embodiment, at a file interposed access protocol layer of a file access client, a file access type operation is received from a file access type layer at the client device. The interposed layer may be interposed between an upper file access layer and an FC layer. The file access type operation specifies a request pertaining to file access. At the interposed file access protocol layer of the client, the file access type operation is modified into one or more sequence of operations so that the operations can be transmitted over an FC network. A sequence of operations are transmitted to an file access server over the FC network.

Disclosed are apparatus and methods for facilitating caching in a storage area network (SAN). In general, data transfer traffic between one or more hosts and one or more memory portions in one or more storage device(s) is redirected to one or more cache modules. One or more network devices (e.g., switches) of the SAN can be configured to redirect data transfer for a particular memory portion of one or more storage device(s) to a particular cache module. As needed, data transfer traffic for any number of memory portions and storage devices can be identified for or removed from being redirected to a particular cache module. Also, any number of cache modules can be utilized for receiving redirected traffic so that such redirected traffic is divided among such cache modules in any suitable proportion for enhanced flexibility.
