FeaturesectionSolutions for the virtual eraHow deduplication helpsreduce the cost of backup anddisaster recoveryBy Kay Benaroch and Shane JacksonDell and EMC have teamed up to deliver efficientdisk-based backup and recovery with integrateddeduplication technology designed to make disk-basedbackups as cost-effective as tape-based backups.Deduplication pays offDell/EMC DD Series appliancesincorporate deduplication and other keytechnologies to help meet storage andbackup challenges.• Up to 99 percent bandwidth reductionfor replication• 90–97 percent data reduction forbackups• Leading defense against data integrityissues with the Data Domain DataInvulnerability ArchitectureToday’s explosive data growth is prompting manyorganizations to look for ways to increase the efficiencyof their storage, backup, and disaster recovery processes.The growth of data is straining capacity, but at the sametime, cost and complexity frustrate many IT managers seeking tomake improvements. For example, tape-based approaches thatworked well when originally implemented can prove to be slow,expensive, and unreliable as the organization grows and as tapesmust be physically transported from remote sites to a centralstorage location. Disk-based backup is inherently faster and morereliable than tape, but has traditionally been more costly, and largedisk arrays can be difficult to manage.Dell and EMC are addressing these challenges by leveraging thedata reduction and cost-saving advantages of deduplication storagesystems from Data Domain, which was purchased by EMC in 2009.Rather than adding deduplication to an existing storage platform, Delland EMC have introduced the Dell/EMC DD Series—purpose-builtappliances that incorporate disk-based storage and deduplication.These appliances are designed to tame data growth as effectively aspossible, helping organizations to reduce complexity and costs.Overcoming challenges to effective data protectionCost pressures can keep many organizations from making neededstorage and backup improvements to cover the variety of operatingsystems, applications, and geographic locations that produce critical28 2010 Issue 02 | dell.com/powersolutionsReprinted from Dell Power Solutions, 2010 Issue 2.
