Deduplication portfolio strategy from HP

HP has selected two deduplication technologies—one for enterprises and one for the SME and remote offices.

Accelerated deduplication, available for HP StorageWorks Virtual Library Systems. Used on HP VLS6000/9000/12000

Dynamic deduplication, built into HP StorageWorks D2D Backup Systems. Used on HP D2D2500 and D2D4000

Figure 4 depicts the latest announced Entry-to-Enterprise level storage devices and their deduplication capabilities.

The HP StorageWorks D2D2500 and D2D4000 Backup Systems implement HP Dynamic deduplication technology. These range in size from 2.25 TB to 7.5 TB and are aimed at remote offices or small enterprise customers. The D2D2500 has an iSCSI interface to reduce the cost of implementation at remote offices, while the D2D4000 offers a choice of iSCSI or 4 Gb FC.

The HP StorageWorks Virtual Library Systems implement HP Accelerated deduplication technology and are all 4 Gb SAN-attach devices that range in native user capacity from 4.4 TB to over a petabyte with the VLS9000 and VLS12000 EVA gateway. Hardware compression is available on the VLS6000, 9000, and 12000 models, achieving even higher capacities. The VLS9000 and VLS12000 use a multi-node architecture that allows the performance to scale in a linear fashion. With eight nodes, these devices can sustain a throughput of up to 4800 MB/sec at 2:1 data compression, providing the SAN hosts can supply data at this rate. HP Virtual Library Systems will deploy the HP Accelerated deduplication technology.
