The IBM 3590 tape system was recently replaced by an IBM 7720 tape subsystem. This project took place because of the large number of issues with old technology and the increasing costs of maintenance fees.
Chuck reviews the IBM 3590 one last time.
The new equipment arrived early in October 2010 and was installed within the month. The migration of the old 3590 tape to the new 7720 started immediately after that installation, and migration was completed in the middle of December. Physical power to the 3590 was turned off the first week of January 2011, and then the unit was dissembled. Data is synchronized to an identical 7720 located in the Mandan Data Center just five minutes after data is written in Bismarck.
