Compression and Storage Tek's ExHPDM

CA Tape Encryption provides support for the Extended High-Performance Data Mover (ExHPDM) product from Sun Microsystems / Storage Tek. ExHPDM users are cautioned that ExHPDM run times may be elongated when encrypting data with CA Tape Encryption. Run-time elongation may be more significant when the Integrated Compression feature of CA Tape Encryption is also selected for the encrypted volumes. CA strongly encourages ExHPDM users to evaluate if data compression is needed for the ExHPDM encrypted volumes and in that case, to test production-like workloads to verify if the required resources will be available in the production environment.
