1. A method for performing host side deduplication before accessing a storage server, comprising:

  • receiving a write request at a host computing device configured to access data stored by a storage server, the write request comprising a request to store writeable data to the storage server;

    computing a signature for the writeable data, the signature uniquely identifying the writeable data;

    querying a data structure to determine whether the signature is specified within the data structure without accessing the storage server, the data structure comprising one or more signatures uniquely identifying data stored by the storage server, the data structure hosted on the host computing device;

    if the signature is specified within the data structure, then sending a deduplication notification to the storage server, the deduplication notification excluding the writeable data; and

    if the signature is not specified within the data structure, then sending a write command to the storage server, the write command comprising the writeable data.
