HPE StoreVirtual VSA (Virtual Storage Appliance) is a Software- Defined Storage (SDS) solution, that creates a scale-out, server- side virtual SAN using industry-standard hardware. This product has the full functionality of the HPE StoreVirtual 4000 hardware- based appliance but is implemented as a virtual machine in a VMware vSphere, Microsoft Hyper-V or KVM environment. (See the HP StoreVirtual 4000 Product Brief for further information)
StoreVirtual clusters typically consist of between three and 32 servers or “nodes”, although two-node clusters are also supported with a “Quorum Witness” running on a third system. Each VSA license has a maximum of 50TB of capacity, meaning nodes can contribute up to 50TB to the cluster. While up to 32 nodes can participate in the cluster, in practice, it’s common to create several smaller clusters to limit fault domains. Multiple clusters can then be aggregated into Management Groups, which can all be controlled from a single Centralized Management Console.
HPE StoreVirtual is a family of scale-out storage systems created through the integration of the HPE LeftHand OS software running on HP ProLiant servers with disk or solid state storage attached. The VSA version of the StoreVirtual system leverages this mature product to utilize existing server storage and provide the same
functionality, while protecting the customer’s hardware investment. In fact, HPE offers the VSA software free with every HP ProLiant server deployment, but it can also be installed on any appropriately-configured x86-based server as well.
In addition to hard disk drives, solid state devices (SSDs) are supported in an all-flash tier for high performance capacity or for sub-LUN auto-tiering with StoreVirtual’s Adaptive Optimization feature. StoreVirtual VSA clusters can also support externally connected StoreVirtual arrays. Leveraging the Peer Motion feature, this allows data on internal storage to be migrated to a physical StoreVirtual storage array as storage needs evolve.
