A computer accessible medium may be encoded with a plurality of instructions which, when executed in a first node of a plurality of nodes in response to a fail over of a first service group of a plurality of service groups from a second node of the plurality of nodes, initiate lock recovery for locks on one or more filesystems included in the service group. Locks on one or more filesystems in a second service group of the plurality of service groups may be maintained during a time period that locks in the first service group are recovered. The lock recovery may be initiated using a first client list of a plurality of client lists, wherein the first client list is included in the first service group and identifies clients having at least one lock on a filesystem included in the first service group. During the fail over of a service group, lock services may not be interrupted for other service groups on any of the nodes.

Methods, systems, and computer readable media are provided for accessing and compressing data stored in a media library, as well as tracking optical media with media tags and cartridge manifests within a library. In one embodiment, a simulation layer of a hybrid storage appliance allows libraries of optical media with write-once read-many (WORM) properties to look like logical block devices with non-WORM characteristics. In another embodiment, data from a user's files is compressed by the media library appliance in chunks in such a way that coarse granularity seeking is possible within a compressed user file. In another embodiment, a media cloud is used by a hybrid storage appliance to seamlessly recover from failures in optical media, library robotics, optical drives, and network connections during the creation, recovery, and distribution of data. In another embodiment, cartridge manifests and media tags are used to track optical media within a library.

A bridge in a file server provides a direct link to data storage devices in satisfaction of data requests. The file server has one or more function-specific processors, including network processors (NPs) and file storage processors (FSPs), all operating in parallel and communicating over an interconnect bus. Each FSP is also connected to one or more disk controllers which in turn manage one or more data storage devices. To minimize local bus contention between data storage devices and network communications, separate internal buses are provided in the FSP, one internal bus connected to the interconnect bus for network communications and one internal bus connected to disk controllers for performing I/O operations on data storage devices. The bridge provides a path between the FSP's internal buses so that, for disk access requests, data from a particular data storage device may be sent by the disk controller via the bridge over the interconnect bus to the NP servicing the request with minimal involvement of the local FSP processor.

A scalable computer system has an interconnect bus providing communication links among a host processor and one or more function-specific processors, including a network processor (NP) and a file storage processor (FSP). The host processor provides a single interface to network administrators for maintaining the system. A bi-endian conversion system is provided to minimize a need for translating between big and little endian data types generated by diverse processors. The NP shares a single memory image with other processors and has a buffer memory for buffering requests from the network interfaces. The buffer memory has one or more segments which are dynamically allocatable to different processors. The FSP has a metadata cache for maintaining information on data being cached in the NP buffer memory. The FSP also has a write cache for buffering file write operations directed at disks.
