This article provides examples of the different ways StorMagic SvSAN can be deployed for both primary virtual machine storage and backup infrastructures. It also highlights common deployment architectures and supporting technologies.
SvSAN Leveraged as Virtual Machine Storage
Being block-based storage, SvSAN can be deployed in a wide variety of environments.
The most common deployment is as shared virtual machine storage for hypervisors. Its lightweight architecture, hardware independence, hypervisor flexibility, simplicity, and resilience allow deployments ranging from a handful of remote sites to thousands of clusters.
SvSAN has been successfully deployed in environments ranging from fewer than ten remote offices to installations exceeding 6,000 sites.
Example of a large-scale ROBO deployment.
SvSAN is equally suited for small and medium business (SMB/SME) environments.
Example SMB deployment.
It can also be deployed within traditional datacenter infrastructures, including environments such as HPE Synergy clusters.

Across all deployment models, SvSAN's synchronous mirroring, caching, and data-at-rest encryption eliminate single points of failure while enabling technologies such as live migration, high availability, improved storage performance, and physical data protection. Combined with third-party backup technologies, these capabilities provide complete Edge-to-Center and Edge-to-Cloud data protection solutions.
SvSAN Leveraged as Backup Storage
SvSAN can also be used as part of a backup architecture, either by protecting virtual machine data directly to cloud services or by providing local backup storage before data is copied to the cloud or another datacenter location.
ROBO – Edge Direct to Cloud
This scenario is targeted at large-scale ROBO customers that want a minimal on-premises hardware footprint. Some environments use small commodity NAS devices on-premises, but cloud backup services can remove the need for that additional local hardware, reducing support overhead and complexity.
| Advantages | Disadvantages |
|---|---|
| Lightest-weight on-premises hardware footprint | More WAN traffic |
| Lower capex | Higher opex |
| Least complex | Longer restore time |
The diagram below demonstrates different vendor options with on-site SvSAN backing up guest virtual machines directly from SvSAN to the cloud.

ROBO/SMB/SME – Edge to Local to Cloud
In this scenario, SvSAN serves both production virtual machine data and backup storage within the same site or host environment.
| Advantages | Disadvantages |
|---|---|
| Less WAN traffic | Heavier on-premises footprint |
| Lower opex | Higher capex |
| Faster restore because some data is stored on-premises |
This deployment can use SvSAN as the primary virtual machine storage volume while a third dedicated backup node provides backup storage. The backup storage may run SvSAN as a shared, non-mirrored storage volume or operate independently of SvSAN.

The same concept can also be implemented using a dedicated backup cluster.

Backup storage can also be hosted directly within the production systems themselves, depending on the requirements of the environment.

Datacenter – Backup Target
SvSAN can also be deployed as a highly available backup repository for centralized datacenter environments.
| Advantages | Disadvantages |
|---|---|
| Highly available synchronously mirrored backup target | Largest on-premises infrastructure footprint |
| Can be stretched to another location (≤20 ms latency) | Higher infrastructure cost |
| Backup target can be customized using flash or large-capacity HDD storage |
Backup targets can also be stretched between locations while maintaining synchronous storage replication where latency requirements are met.
