Reliable backup, recovery and archiving solutions are Quantum's territory. The main business solutions Quantum offers are the well known tape libraries. Increasingly often, backup-to-disk based solutions are being chosen with those, therefore representing a growing part of the Quantum portfolio.
Quantum DXi - de-duplication
The Quantum DWi platform is a disk based backup appliance, also known as Virtual Tape Library (VTL). The Quantum DXi contains advanced data de-duplication and compression technology. This makes available storage capacity 10 to 50 times more efficient than conventional storage methods, using the same storage capacity a single full backup would.
De-duplication at block level
Many existing products featuring de-duplication techniques at file level. Quantum DXi de-duplicate on block level, automatically storing only changes within files.
High throughput levels
Quantum DXi 3500 offers throughput speeds of 290Gb per hour, 80Mb per second. These speeds compare to a high performance LTO-3 drive. The Quantum DXi 5500 even offers as much as 800Gb throughput per hour, comparable to the speed reached by three LTO-3 drives.
Many current de-duplication devices offer merely a fraction of these throughput levels.
Existing environments
Backup software configured for existing Tape Libraries do not need to be adjusted and Quantum DXi comes with Fibre Channel as well as iSCSI interfaces, making it applicable in any SAN or NAS environment.
Remote replication over IP
Two or more Quantum DXi systems may replicate between themselves. Thus, at one or more locations, completely automatically, data copies will be realized on the primary system. This replicated data is to be used when fallback is needed and enables off-site storage of data backups as required in many data security protocols. Replicationdata being transmitted between two Quantum DXi appliances is being reduced by the same de-duplication technique to a mere fraction of its actual size.
NAS access
Through a built in CIFS (Windows) NAS server, Quantum DXi offers access to file-based backup and archiving systems. Doing so, the DXi may be used to save data from disk-based backups or archiving software, using intelligent data de-duplication. These solutions offer a data reduction of 10 to 50 times.
