Model	2863-A10 – Single Controller
	2863-A20 – Dual Controller
Highlights	● Installation—Offers installation tools designed to help simplify installation and setup	● Operational Efficiency—Designed to help businesses meet the growing challenge of managing and securing
	● Increased access—Allows heterogeneous access to IP attached storage	retention managed data and other critical information assets over extended periods of time
	● Flexibility—Enables cross-platform file sharing for Microsoft Windows, UNIX and Linux environments that can	● Integrated offering—Designed as a preconfigured, integrated offering to help store, retrieve, manage, share
	help reduce network complexity and expense, and allow data to be shared across the organization	and secure regulated and nonregulated data in non-erasable and non-rewritable format
	● IP SAN – Supports iSCSI protocols for IP SAN attachment to a multitude of host servers including Microsoft	● Automation—Designed to offer automatic provisioning, migration, expiration and archiving capabilities
	Windows, UNIX and Linux systems	● Scalability—Supports nondisruptive enterprise scalability of up to 56TB physical capacity and supports
	● Scalability—Supports nondisruptive capacity increases up to 16TB of physical storage	petabytes of storage with attached tape
	● Manageability—Includes integrated system diagnostics and management tools, which are designed to help	● Policy-based—Offers a comprehensive suite of software tools for policy- and event-based data management
	minimize downtime	● High Availability—Option designed to avoid single points of failure
	● Redundancy—Offers redundant fans, power supplies, disk drive, and clustered controllers	● Native support for LTO Gen 3 WORM Tape
	● Copy services—Provides extensive on-board and out-board disaster recovery data protection features	● 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.
