Flexibility for future growth
Provision just the compute power and storage needed today and easily grow in the future. You can add CPU, memory and any disk storage type whenever needed – without downtime. Since storage is now separate from the application servers, it’s easy to scale compute and storage independently.
There are 3 primary deployment models available:
Single server: By deploying SvSAN on a single server, costs are kept to a minimum but there is no protection against a server failure. This is perfect for non-critical environments like testing & development, proof of concept, training and home labs.
Local mirrored cluster: Deploying SvSAN on two local servers creates a highly available cluster which provides protection against a server failure. Data is synchronously mirrored between the nodes ensuring it is always available. Local mirrored clusters are perfect for business critical applications and valuable data requiring protection.
Stretched cluster: The two clustered storage servers can be located in different server racks, at opposite ends of a datacenter or between buildings on a campus or across the city. This physical separation provides an added layer of resiliency to keep storage available to the application servers even during a local disaster (power loss, fire, flood, etc…). Stretched clusters are perfect for the most demanding environments that have 2 or more datacenters or a campus with multiple buildings.
