Information
Being block based storage SvSAN is able to be used in a great variety of ways.
The typical use case is simply as a VM hard disk SAN storage volume for hypervisors. This being most powerful due to it’s light weight and robust nature, alongside the flexibility to be agnostic to the hardware and hypervisor platform it’s run on, simplicity and robustness enabling it to be deployed at the scale of thousands of clusters.
SvSAN leveraged as Virtual Machine storage
This has enabled SvSAN to be deployed into both large scale ROBO use cases, in environments ranging from <10 remote sites all the way up to >6,000
To SME/SMB use cases:
and even datacenter like environments such as HPE Synergy clusters similar to the below:
In each of the above SvSAN’s synchronous mirroring, caching and data-at-rest encryption technologies eliminate any single point of failure, enable live migration, HA, storage performance and physical security from theft however it is when combining with other technologies that a solution stack to solve SMB/SME, Edge-to-Center and Edge-to-Cloud backup options.
SvSAN leveraged as backup storage
ROBO - Edge direct to Cloud
This scenario is targeted at those large scale ROBO customers, looking for minimal on-prem hardware. We have seen many users in this space leveraging small commodity NAS boxes boxes on-prem, however with different vendors offering cloud backup services it is possible to remove the need of this on-prem piece, removing support and complexity.
| Advantages | Disadvantages |
|---|---|
| Lightest weight on-prem hardware footprint | More WAN trafffic |
| Lower capex | Higher opex |
| Least complex | Longer restore time |
The below digram demonstrates different vendors with on-site SvSAN backing up Guest VMs from SvSAN direct to the cloud.
ROBO/SMB/SME - Edge to local to Cloud
Or SvSAN as both serving the VM data and the backup storage within the same hosts
| Advantages | Disadvantages |
|---|---|
| Less WAN traffic | Heavier on-prem footrpint |
| Lower opex | Higher capex |
| Faster restore as some data stored on-prem | |
This can be SvSAN as a VM storage volume with a third dedicated backup node, running SvSAN as a shared but non-mirrored storage volume or independent of SvSAN.
or cluster
Or within the systems themselves
Datacenter - Backup target
| Advantages | Disadvantages |
|---|---|
| Highly available and synchronously mirrored backup target | Heaviest on-prem solution |
| Can be stretched to another location (≤20ms latency) | More cost |
| Customizable backup target e.g. flash based or LFF HDD in the 100s of TB | |
SvSAN as a backup target can even be stretched
