While tape backups are often seen as a less expensive alternative to disks, Goulden argued that disk-based systems can bring a return on the additional investment. Data Domain systems, for instance, have deduplication technologies that can cut storage requirements by as much as 30 percent. An organization can also use the disk backups as the basis of a disaster recovery system, which would eliminate the cost of running a separate system for that functionality, Goulden said.
Overall, the new systems are four times as fast and 10 times as scalable as the midrange EMC platforms they replace, according to the company. A DD7200 system can serve up to 26 terabytes per hour using the company's DD Boost protocol. The system can store up to 428 terabytes, or 1.7 petabytes in a clustered configuration. These systems can support up to 540 data streams, a threefold increase from earlier iterations. Overall, they provide a 38 percent lower cost per gigabyte, EMC claims.
EMC has sold more than 36,000 Data Domain systems since its launch in 2003, the company said.
The new version of EMC's Avamar software product brings new backup capabilities to virtualized environments. A new feature in Avamar 7, VM Instant Access, allows a VMware-based virtual machine (VM) to be booted from an EMC Data Domain system in under two minutes. It also now offers a VMware vSphere client so that administrators can back up their VMs directly from the VMware management console. Avamar can also now back up Isilon network-attached storage (NAS) arrays.
The EMC NetWorker backup and recovery software has been updated as well. NetWorker can now deliver backups to Data Domain systems through Fibre Channel, cutting the time of backing up material by potentially as much as 50 percent. Restoring data can be made two-and-a-half times as fast with this setup as well. Version 8.1 comes with a new Wizard-style interface.
EMC acquired both Avamar and NetWorker technologies in separate company purchases: Avamar in 2006 and Legato in 2003. Over time, EMC will downplay the brand names and offer both products as components under the Data Protection Suite, Goulden said.
"The products will increasingly come together," he said. "No enterprise has only one app, so you need a suite of tools. So essentially what we are saying is, license this suite and as your needs change, you can use more of one piece than another."
EMC has also updated its Mozy storage backup service to make it easier for enterprises to use. The service now allows organizations to manage multiple accounts in storage pools. Rather than each account getting its own storage quota, an organization can pool all the accounts into one single quota, which means individual users won't have to spend as much time worrying about how much storage they've used. A new form of activation will allow users to sign on to the service without an authentication key, which EMC says could cut activation time considerably.
EMC will provide more details about the new products at a webcast launch to be held Wednesday.
