A cluster is one of the most secure storage setups that can effectively increase performance, reliability or capacity in an IT environment. Workloads are balanced, files are accessible at all times and features such as failover ensure Business Continuity. Learn more about clusters with Open-E software.
A Cluster-in-a-Box system houses two servers and a common set of direct attached hard drives within one server enclosure. This system simplifies the physical setup and deployment of a two-node High Availability storage cluster since all necessary connections are pre-configured between the inner components.
The Failover feature provides High Availability of data. In an iSCSI Failover setup of two servers, data is saved on both servers simultaneously. When one system fails, its processes and all resources are being relocated to and restarted on the second node. The Active-Passive setup allows having all volumes active on one node (the primary node), while the other node has all passive copies and takes over the tasks in case of an emergency (the secondary node). A load-balanced Active-Active Failover on the other hand, doesn’t have a primary or secondary node. It adds extra performance by enabling the user to decide which volumes are active on which node. The failover process is the same, but the servers are able to utilize their full network performance and eliminate the unnecessary cost of idle hardware.
Having a highly available storage is one thing, but what about its overall performance? Learn how you can achieve both, using Open-E DSS V7 with iSCSI Active-Active Feature Pack.
The Avago Syncro™ technology is a solution for businesses of all sizes that require high available storage for high performance, high capacity or hybrid system. The Syncro™ CS solution is a hardware based, high-available DAS which is shared between two head-nodes. In combination with Open-E DSS V7 software, it is possible to create a customized solution for any need, from a high performance SSD storage to high capacity 3,5” HDD server with SDD caching.
Failover Cluster allows multiple computers work together in order to provide high availability of some services. In case of a situation when a node responsible for a service fails, the second one is able to take over this service and prevents from an unexpected downtime.
