●
High Availability—Option designed to avoid single points of failure
●
Native support for LTO Gen 3 WORM Tape
●
Flexibility—Application program interface (API) client program makes it easy to integrate ISV Content
Management applications
●
Synchronous Replication—Supports Metro Mirroring allowing two real-time synchronized copies of the data to
be maintained on DR550s in separate locations.
●
Disaster Recovery support—DR550 protects customer data during disasters.The DR550 solution allows busi-
nesses to use tape libraries with advanced LTO Gen 3 tape drives with WORM capabilities to provide efficient
and cost effective replication of data objects.
●
Operating in conjunction with an enterprise content-management product like IBM DB2 Content Manager for
Message Monitoring and Retention (CM MMR) helps enable centralized management through a single inter-
face to support storage allocation and address application demands.
