Hitachi Dynamic Link Manager 5.5 (04421020703AP) Recommendations

Hitachi Dynamic Link Manager software provides Hitachi Freedom Storage customers with a robust path fail over and load balancing solution for improvements in access to, and availability of, information. One of the first steps to data protection is realizing that incidents outside the realm of disasters can seriously jeopardize information availability. Protection needs to begin as soon as data leaves the server. The path between a host and a storage system is a potential point for information bottlenecks or failure. The capabilities of Hitachi Dynamic Link Manager (HDLM) software, automatic load balancing, path fail over and failback, provide an incremental level of higher availability and accessibility to data. If one path fails, the HDLM path fail over feature automatically switches the I/O to an alternate path, ensuring that an active route to your data is always available.
