Quantum expands on dedupe

* Quantum releases high-end disk backup system

Quantum last week played the de-dupe card again with the introduction of a high-end disk backup systems that can scale to as many as 240TB.

The DXi7500 offers data-deduplication and multi-site remote replication capabilities. It is part of the company’s DXi family of disk-based backup systems and is compatible with the smaller DXi3500 and DXi5500 models. The DXi3500 has a 6TB capacity; the DXi5500 supports 16TB.

The system is intended for large enterprise environments. With the DXi7500, customers can transmit data from a single or several remote sites to the DXi7500 as long as the remote sites are equipped with other DXi systems. Data replication is asynchronous and operates as a background process.

The DXi7500 can be connected to a Fibre Channel or iSCSI network as a virtual tape library or to the Ethernet network, where it will process Microsoft’s Common Internet File System (CIFS) or the Unix/Linux Network File System (NFS) data.

Quantum’s method of deduplication is performed either in-line or post-processing. With policies, customers can determine which form of deduplication to use. By contrast Diligent and data Domain employ inline processing; Sepaton offers post-processing.

According to Quantum’s claims, its deduplication technology can reduce the amount of data being backed up by 50 times. The deduplication capability comes to the DXi family from the acquisition of ADIC, a company that had previously acquired Rocksoft.

The DXi7500 has performance of as much as 9TB per hour.

Pricing is not available. The DXi7500 is expected to be released this fall.
