InfiniBox Active-Active replication provides zero-RPO and zero-RTO, enabling mission critical business-services to keep operating even through a complete site failure:
- Symmetric synchronous replication solution, applications can be geographically clustered
- Fully integrated into InfiniBox, allows simple management of application spread across data centers.
Further information about Active-Active replication is available on:
- Active-Active volume: a volume that is undergoing Active-Active replication.
- Peers: a pair of volumes that are undergoing Active-Active replication relationship, are also referred as "peers".
- Active-Active datastore: a datastore that resides on an Active-Active volume.
- Active-Active virtual machine: a virtual machine that is housed on a datastore which resides on an Active-Active volume.
- ALUA: asymmetric logical unit access.
Supported Configurations for vSphere with InfiniBox Active-Active Replication
In order use vSphere with InfiniBox Active-Active Replication, a proper and validated configuration is required.
For further information see the following guide: "VMware vSphere Metro Storage Cluster with INFINIDAT InfiniBox Active-Active Replication".
VMware vSphere Metro Storage Cluster (vMSC) is a specific storage configuration that combines replication with array-based clustering. These solutions are typically deployed in environments where the distance between data centers is limited, often metropolitan or campus environments.
- The primary benefit of a stretched cluster model is that it enables fully active and workload-balanced data centers to be used to their full potential and it allows for an extremely fast recovery in the event of a host or even full site failure.
- vSphere ESXi servers are in a single vCenter cluster and can be spreaded across sites (separate datacenters or geographic areas)
- PowerTools for VMware: Active-Active volumes are supported with Host PowerTools fir VMware v5 and above.
- InfiniBox: Active-Active replication is supported with InfiniBox version 5 and above.
- For additional information about the supported configuration, please refer to:
- vSphere: For the supported vSphere version see: Interoperability Matrix for the InfiniBox F-Series
Host PowerTools for VMware and Active-Active volumes
Host PowerTools allows to manage Active-Active volumes and provides end-to-end relationships between Active-Active volumes and local host.
Creating Active-Active volumes is available via the InfiniBox management consoles (Web GUI or InfiniShell).
- Currently not available through Host PowerTools.
ESXi hosts and Active-Active Volumes Relationships
ESXi hosts identify both peers as the same multipath device.
- InfiniBox Active-Active volumes are supported by ESXi native multipath software.
ESXi Hosts can access Active-Active datastores in one of two ways.
Hosts can access both peers. (both systems)
Each host can access only one of the peers. (one of the systems only)
