Rating: (0)

Overview: The mirroring of data between two remote sites has become significantly easier with the arrival of the new HACMP/XD for Geographic Logical Volume Manager (GLVM) solution. As an IP-based solution, GLVM sites can span an almost unlimited distance. In GLVM, the AIX 5L LVM (Logical Volume Manager) itself is responsible for mirroring the data; thus several complex and time consuming manual tasks have been eliminated. The configuration and management of GLVM is therefore simpler and with fewer geographical limitations than other remote mirroring solutions. But, as with any remote mirroring solution, it is still important to design and tune for optimal performance.
