To ensure uninterrupted access to critical medical data, Perot uses EMC MirrorView(TM) software to replicate DCHS's Quadramed CPR application stored on a CLARiiON system to another CLARiiON system at a separate datacenter. Perot also archives DCHS's older radiology and cardiology images and data to an EMC Centera(R) content-addressed storage system, which is replicated to another Centera system. DCHS hospitals and datacenters also use EMC EmailXtender(R) to archive older emails from a CLARiiON system to a Centera system.
"Because we care for patients around the clock, we protect our data in many ways," said Day. "If our patient records application was knocked offline, we'd fail over to our remote site within seconds. By archiving to EMC Centera, we retrieve older records in less than a minute compared to 30 minutes for tape. Offloading 'heavy' files, like CT scans, from the SAN to Centera also shrinks the amount of data we need to back up, which contributes to faster backups and restores."
Based in Los Altos Hills, Calif., DCHS has replaced its Veritas Backup Exec tape solution with EMC NetWorker, which enables the hospitals and datacenters to back up data initially to CLARiiON and move it over to tape for long-term storage.
Chris Dunning, the Senior Network Engineer from Perot working with DCHS, said, "We centrally monitor how our backups are running at the hospitals. If we discover a backup wasn't complete, we're able to get it back on track quickly. Back up to disk is also faster. Before, a backup would barely complete before the next one was due to kick off. Now, we have more breathing room
