摘要： The present invention defines a new protocol for communicating with an offload engine that provides Transmission Control Protocol (“TCP”) termination over a Fibre Channel (“FC”) fabric. The offload engine terminates all protocols up to and including TCP and performs the processing associated with those layers. The offload protocol guarantees delivery and is encapsulated within FCP-formatted frames. Thus, the TCP streams are reliably passed to the host. Additionally, using this scheme, the offload engine can provide parsing of the TCP stream to further assist the host. The present invention also provides network devices (and components thereof) that are configured to perform the foregoing methods. The invention further defines how network attached storage (“NAS”) protocol data units (“PDUs”) are parsed and delivered.

摘要： Techniques are disclosed for abstracting write acceleration techniques and tape acceleration techniques away from transport providers (e.g., away from an FC or FCIP interlink between two storage area networks) and allowing acceleration to be provided as a service by nodes within the storage area network (SAN). Doing so allows the acceleration service to be provided anywhere in the SAN. Further, doing so allows users to scale the acceleration service as needed, without having to create awkward topologies of multiple VSANS. Further still, as the acceleration service is offered independently from the transport, compression, encryption, and other services may be offered as part of the transport between the FC/FCIP connection along with the acceleration service.

摘要： Techniques and a network edge device are provided herein to extend local area networks (LANs) and storage area networks (SANs) beyond a data center while converging the associated local area network and storage area network host layers. A packet is received at a device in a network. It is determined if the packet is routed to a local or remote storage area network or local area network. In response to determining that the packet routed to a remote storage area network, storage area network extension services are performed with respect to the packet in order to extend the storage area network on behalf of a remote location. In response to determining that the packet is routed to a local local area network traffic, local area network extension services are performed with respect to the packet in order to extend the local area network on behalf of the remote location.

摘要： An encryption key management system is provided for storage area network devices. A create key request is received at a storage area network switch. The key is created at the storage area network switch and the created key request is transmitted to a key management center. The key object is stored in the key management center and includes a unique identifier, an encrypted key, a wrapper unique identifier, and a key entity. The encrypted key can later be decrypted to generate a decrypted key. The encrypted key is decrypted using keying material accessed using the wrapper unique identifier that identifies another key object.

摘要： Techniques are disclosed for redirecting fiber channel data transmitted between nodes in a fiber channel fabric. The redirection allows traffic sent from a host to a target in a storage area network (SAN) to flow through a cascade of applications provided by certain nodes of the fabric (or in some cases, by external appliances). That is, techniques are disclosed for application chaining in the SAN. Doing so allows the SAN to be used as a true network platform for providing a variety of intelligent services within the network (e.g., data migration, encryption, etc).

摘要： Mechanisms are provided for generating a master key used to secure key objects associated with data blocks in a data center. A cryptographic node creation request is received. It is determined that a master key can not be obtained from another cryptographic node in the data center. A master key is generated. The master key is included in a key hierarchy used to encrypt a data center key object, the data center key object corresponding to a data block maintained in a storage area network (SAN), where the data center key object includes a unique identifier, an encrypted key, and a wrapper unique identifier. The master key is split into N shares, with M shares required to recreate the master key, wherein M is less than N. The N shares are distributed to different entities.

摘要： Disclosed are methods and apparatus for redirecting fibre channel data that is transmitted between a first and a second node, such as a host and target, in a storage area network (SAN) to an intelligent node that facilitates implementation of a service on such redirected data. Such redirection is provided transparently with respect to the first and second nodes without significantly reconfiguring the existing infrastructure of the first and second nodes. In a specific Fibre Channel implementation, the redirection is accomplished without rewiring any of the nodes in the network fabric or reconfiguring zones or virtual storage area networks (VSANs). In general, such redirection is accomplished by rewriting the data as it traverses on a path between the first and second node towards an original destination (e.g., the first or second node) so that the data is redirected to an intelligent node. The intelligent node then facilitates implementation of a service on such redirected data and then forwards the serviced data back to its original destination. In one example, setup of this redirection function is accomplished simply by making a request to a network device (e.g., a host and/or target switch) in the first and second node's communication path, where the request identifies the first node, the second node, and the intelligent node.
