DuPage Medical Group (DMG) is one of the largest and most successful independent multispecialty physician groups in Illinois and has more than 425 physicians practicing in 50 medical and surgical specialties.
DuPage chose clustered Data ONTAP to address their primary concerns of high availability and upgradability. Because their IT infrastructure serves 50+ separate medical facilities, it’s critical for them to eliminate downtime—both planned and unplanned. The HA architecture and nondisruptive operations capabilities of clustered Data ONTAP allowed them to upgrade or do other maintenance without users knowing that anything has happened.
They have one cluster in each data center with four FAS3250 nodes per cluster, the multiple storage nodes allows them to better load balance workloads across more nodes.
In 2013 DMG had two IBM N-Series storage systems running in 7-Mode. (N-Series were NetApp systems sold through an OEM agreement.) Not only was DMG changing from 7-Mode to clustered Data ONTAP, but they were doing an almost complete physical to virtual migration of their server environment at the same time.
To accomplish the storage migration, DMG worked with their partner Meridian IT who provided a DTA2800, which allowed DMG to migrate the data from their old SAN environment. Because in many cases they were re-building systems in the process (e.g. new Exchange servers, new SQL servers) it was often just a matter of moving the data over once the new application environment was ready.
The whole transition took about ten months, which was considered pretty fast. A lot of people were shocked that DMG IT did it that quickly. There were some painful moments, but that was because DMG had a lot of complicated systems, not because the storage transition was difficult.
Benefits of the new solution.
