DOT HILL DELIVERS SOFTWARE TOOLS FOR VOLUME MANAGEMENT AND EXTENDS OPEN SYSTEMS PLATFORM SUPPORT.

Dot Hill Systems Corp. (NYSE: HIL), today announced exciting enhancements to its suite of storage area network (SAN) management software applications SANpath[TM] 3.1 and SANscape[TM] 2.3. SANpath 3.1 now delivers dynamic LUN assignment, an advanced timesaving capability that dynamically allocates and re-allocates server storage resources "on the fly" without interrupting critical applications. SANpath 3.1 also adds Linux, HP-UX, and Windows 2000 to its list of supported platforms. SANscape 2.3 is now even more tightly integrated with SANpath and provides IT Managers with an intuitive, easy-to-use "drag & drop" user interface for managing storage allocation operations, and also adds HP-UX, Linux, Windows 2000 and Netware to its list of supported platforms. Both applications work with Dot Hill's carrier-class SANnet[TM] storage solutions to enhance performance, simplify storage management, and protect against component failures. Availability for both releases is expected in mid August 2000.

When used together, SANpath and SANscape provide a nearly seamless SAN management environment. With the new releases, IT Managers can dynamically change and manage critical storage resources without interrupting business operations. In the past, "scheduled" and often costly downtime was required to allocate or re-allocate storage resources to servers. Now, IT Managers can grow or change storage resources on servers in their Storage Area Networks without taking servers or critical applications off-line.

SANpath 3.1 ensures constant availability of data across a SAN, enhances network-server bandwidth, and permits dynamic LUN assignment and reassignment of storage resources without server restarts. SANpath 3.1 also provides LUN Masking capabilities, which allows multiple servers to share a common storage system. SANpath 3.1 supports single and multi-server environments and is compatible with current industry standard platforms including Windows NT/2000, Solaris, HP-UX and Linux.

SANscape 2.3 combines SAN configuration, maintenance and monitoring tools while presenting a consistent easy-to-use graphical user interface. It provides centralized administration of Dot Hill's SANnet storage systems (SCSI and Fibre) across existing LANs and WANs and can notify Dot Hill's Global Response Centers via e-mail in the event of a problem. SANscape greatly simplifies storage management, and can dramatically reduce SAN administration costs. SANscape supports single and multi-server environments and is compatible with current industry standard platforms including Windows NT/2000, Solaris, HP-UX, Netware, and Linux.
