Techniques for managing caching use of a solid state device are disclosed. In some embodiments, the techniques may be realized as a method for managing caching use of a solid state device. Management of the caching use may include receiving, at a host device, notification of failure of a solid state device. In response to the notification a cache mode may be set to uncached. In uncached mode input/output (I/O) requests may be directed to uncached storage (e.g., disk).

A system and method are disclosed for storing data in a hash table. The method includes receiving data, determining a location identifier for the data wherein the location identifier identifies a location in the hash table for storing the data and the location identifier is derived from the data, compressing the data by extracting the location identifier; and storing the compressed data in the identified location of the hash table.

Techniques for managing cache configuration are disclosed. In some embodiments, the techniques may be realized as a method for managing creation of nodes names and references to source devices during detection of storage devices (e.g., a physical devices such as a SCSI Disk, a redundant array of independent disks (RAID), or logical devices such as logical volume management (LVM) volumes or automatic storage management (ASM) volumes). Management of cache configuration may include creation of rules to generate node names upon detection of source and/or cache devices. Management of cache configuration also may include the creation of rules to create caches or initiate creation of caches upon successful creation of source devices and cache devices corresponding to a cache. Management of cache configuration may include management of the creation of symbolic links to a cache of a source device.

A dynamic session redirector provides the ability to receive requests for network accessible storage resources and redirect them to the appropriate resources as needed while providing a single system image to the system requesting access to the resources. The redirector provides an ability to reconfigure the network storage resources without altering the system image presented by the redirector to the clients on the network. This may be used to provide for dynamic reallocation of the resources in order to improve efficiency and reliability of the storage system, as well to provide support for a wide variety of protocols to be redirected, including stateful protocols.

Dynamic network session redirector

A dynamic session redirector provides the ability to receive requests for network accessible storage resources and redirect them to the appropriate resources as needed while providing a single system image to the system requesting access to the resources. The redirector provides an ability to reconfigure the network storage resources in order to balance the load among the servers. By altering the association between individual storage resources and the servers responsible for them on the storage network, a more efficient and reliable system for access to the data may be provided.
