high available Cluster with No-single-Point-of-Failure!
Zstor HA Cluster as high available solution
Based on NexentaStor 3.x and the NexentaStor HA cluster software plugin, the Zstor HA cluster solution offers a no-single-point-of-failure design for the maximum availability of your data. Optimized and high-performance hardware for cluster nodes and JBODs in combination with the innovative possibilities of the ZFS file system offer enterprise class features at an affordable price level.
The Zstor HA cluster can run as active/active or active/passive cluster. Each instance can provide all services and applications at any time at the disposal. The internal redundancy, data integrity is ensured constantly mechanisms of the ZFS file system. The cluster design helps to ensure that the failure of a single component in the cluster don't mind the running processes. Automatic failover mechanisms, the function in the cluster takes over the remaining cluster node automatically. As well, the failure at one JBOD courses no data loss due to synchronous mirroring of data. The services and applications on the hosts remain transparent at any time. No manual intervention must occur on the host side to keep data available.
The capabilities of the HA cluster, make it a perfect solution for server virtualization. Zstor HA cluster class provides highly available and cost-efficient storage of the enterprise high-performance computing for virtualized environments including VMware, Citrix Xen, and Microsoft Hyper V. The connection to the host can are made over NFS, iSCSI or FC and all storage management functionalities as unlimited snapshots, replication and cloning are available. Via an additional NexentaStor software plugin VM Datacenter, you can greatly simplify the management of storage for virtualized environments. Cloning of virtual machines via VM Datacenter is considerably faster and easier than with internal tools of the virtualization software.
The needs of cluster solutions are very individual and we consult you within your concept. Some parameters such as the type of the host connection, usage of SSDs to the performance improvement, level of high availability, sizing of cluster nodes and JBODs have significant impact on the performance and features of the system. We support you in finding the Zstor HA cluster high availability to provide solution that fits into your budget.
