Persistent Scalable Volumes

Block Storage

Symphony includes comprehensive block storage and object storage functionality; designed to be extremely scalable, agile and flexible, while fully compatible with the requirements of cloud computing. The storage is native to the hypervisor, to reduce latency and overhead, and to increase throughput. The distributed, high-performance storage service stripes all I/O across each available storage device in the rack, such as HDDs and flash devices, to assure durability in case of failure. Storage functionality can be extended to take advantage of existing storage assets that already exist in the data center.


Allows to persist application data on built in storage or external storage appliances

Data High Availability

Data is replicated across multiple nodes within cluster for safety and durability in case of disk or server failure


Stripes all I/O across each available storage device in the cluster

Cost Effective

Cost reduction by using hyperconverged storage. Enables leveraging existing investments by adding storage appliances to the pool

Future-Proof the Enterprise Data Center

It’s easy and essentially effortless to deliver turnkey cloud-native building blocks to support modern applications on-prem.

Storage Backend Abstraction

Transparently use storage pools from different backends (Hyperconverged, SAN, iSCSI, NFS appliances) to provide storage to the application.


All volumes are accessible from all the servers, enabling any node in the cluster to use the hyperconverged storage even on nodes that do not have local disks.

Thin Provisioning

Only actually written data consumes storage space.

Intelligent Caching

Frequently accessed data blocks are automatically placed on lowest latency devices.

Capacity Balancing

Among all the nodes in the system, eliminating performance bottlenecks.

Space-Efficient Snapshots and Clones

Volume-centric thin snapshots and clones preserve just delta between source volume and its snapshots.

Easy to Use

Minimal configuration for volume deployment.

Quota Services

Admins can allocate storage capacity to tenants, monitor consumption and adjust quota as demand changes.
