| Hitachi Dynamic Link Manager Software provides path failover, failback, and automatic load balancing. Together these features provide higher data availability and accessibility for Windows, Linux, and Sun Solaris environments. If one path fails, the path failover feature in HDLM software automatically switches the I/O to an alternate path, and your data remains available for access. HDLM software also helps maintain outstanding system performance by balancing workloads across available paths.
HDLM supports HP StorageWorks XP Disk Arrays and the equivalent Hitachi storage systems. It enables easy management of paths through a browser based connection to the server. It distributes the load across multiple paths to prevent a heavily loaded path from affecting processing speed. With its path failover capability, HDLM switches to an alternate path if a failure occurs on the active path, allowing processing to continue without interruption. When a failed path is repaired, HDLM will bring it back online to increase the number of paths available for load balancing and failover. HDLM monitors path health by automatically checking path status at regular intervals specified by the user, eliminating the need to repeatedly perform manual path status checks. HDLM can be operated remotely by linking with HP StorageWorks XP Command View Advanced Edition.
