Storage Expo Quantum has enhanced Microsoft's DPM software to fill out its disk-based backup line with an appliance that comes in under its DX series of virtual tape libraries on price.

It has taken DPM and added hardware data compression for doubled disk utilisation, plus software to offload data to tape - although the DPM5500 device does not come with tape as standard.

"DPM brings a very simple snapshot tool, it's simple to use so it suits our target market and our channel very well - the DX plays into more complex environments. I expect people to connect the DPM to a small tape library," said Graham Hunt, Quantum's EMEA product manager.

"We will ship the DPM5500 as a server and software, with three client licences and the tape offload engine," he added.

The DPM5500 has dual Gigabit Ethernet ports with TCP offload engines (TOEs), redundant power and cooling, and can have 4.8TB or 9.6TB of disk.®
