Additional Product Information
Genesis is a highly configurable failover solution allowing two servers ;to be connected to or more disk storage arrays. Designed to prevent ;system downtime in mission critical enterprises, Genesis provides ;automatic server recovery and re-configuration in the event of system failure. ;Servers can be configured to work in either single-active or dual-active;mode. In a single-active configuration, the second server is purely a;standby machine, only becoming active in a failover situation. In a;dual-active configuration both servers are active during normal operation,;and additionally act as standby's for each other. ;In a basic single-active mode two servers are connected to the same;single network and to each other via a serial cable. The serial connection;ensures that communication between the two servers continues in the;event of a network failure. The first server is the active server and has;the disk storage array mounted, whilst the second server is the standby;server. The standby server constantly monitors both the active server;and the network. ;In the event of a failure, Genesis automatically reconfigures the standby;server to become the active server, mounting the first server's disk;storage array, to continue normal operations as if nothing had happened. ;The first server can then be taken off-line and repaired. When Genesis;detects that the first server is back on-line, it automatically control's the;standby server's hand back of the disk storage array before switching it;back to its previous standby mode. ;In a dual-active mode, there are two active servers, each with a disk;storage array attached. In the event of one of the active servers;experiencing a failure, the second active server takes over and continues;with the operations of both servers. ;Genesis Configurations can be tuned as either mass-storage servers or;high performance data servers. To obtain the maximum performance;characteristics, the configuration would consist of two storage arrays;shared by two servers. To obtain high capacity characteristics;the configuration would consist of two servers both with multiple FC-AL;cards providing the connections to daisy chained storage arrays, where;each array contains the maximum number of disks. ;As Genesis is capable of supporting very complex configurations, PCS;provides a special service, covering installation and advice on tailoring;Genesis to meet specific customer requirements, ranging right up to;multi-network dual-active versions.
