HP's StoreVirtual offers either a software defined storage solution or a complete appliance using the same software technology.
StoreVirtual VSA (Virtual Storage Appliance) software transforms internal or direct-attached storage into a fully-featured shared storage array. The product is a virtual storage appliance which is optimised for VMware and Microsoft Hyper-V environments.
This approach enables you to maximise utilisation of existing storage while providing the ability to add storage at any time without affecting performance. High availability and disaster recovery features are also built in.
StoreVirtual VSA gives you the ability to transform existing data storage silos:
StoreVirtual 4000 storage is a scale-out storage platform designed for virtualised environments. It offers high availability, data mobility, disaster recovery, manageability and scale.
Platform integration with VMware and Microsoft increases storage functionality and ease of use while application integration simplifies storage management for applications. Backup and recovery is equally easy with snapshot and Remote Copy integration for virtualisation platforms and Microsoft Windows applications.
HP StoreVirtual is a great way to deploy, manage and grow shared storage. Create shared storage out of internal or external disk capacity (DAS, SAN; FC or iSCSI), and start with a few servers then grow as required.
This approach provides the flexibility you need, but without the up-front costs of new hardware. As your storage requirements grow, new storage arrays can be added without disruption to the business.
