StorMagic SvSAN
What is StorMagic SvSAN?
SvSAN is the virtual SAN that makes the complex world of virtualized storage simple. Perfect for edge computing environments, the technology is based on software-defined storage that eliminates the need for physical SANs. SvSAN is designed to be very simple to install and manage whether deployed as part of a hyperconverged solution or as a storage-only target for any server environment.
How does SvSAN work?
● Creates highly available shared storage across two nodes or more
● Same code, regardless of hypervisor: vSphere, Hyper-V or KVM
● Works on any x86 server, all types of storage and any CPU
What makes SvSAN different?
● Built specifically for edge, SME and small datacenter
● Lightweight, low-cost architecture simplifies deployments
● One tiny witness capable of managing 1000 clusters

How SvSAN Works
SvSAN turns the underlying storage of any x86 server into highly available shared storage within clusters of two servers (nodes) or more. SvSAN sits on top of the hypervisor as a guest virtual machine, and is fully compatible with VMware vSphere, Microsoft Hyper-V and Linux KVM. Its shared storage enables organizations to use advanced hypervisor features.
High Availability
SvSAN’s shared storage works through active-active synchronous mirroring between two servers. This ensures there is always an exact copy of data on each server. If one server suffers a failure or is taken offline for maintenance, the remaining server continues to operate, providing no disruption in service to the organization, and no downtime. This is high availability.
Lightweight Witness
The capability to provide highly available shared storage on a minimum of just two nodes is a defining feature of SvSAN. This is made possible by the use of a very lightweight witness service which can be sited locally or remote to the cluster, can provide quorum for hundreds of clusters at a time, and will run on as little as a Raspberry Pi.
What Makes SvSAN Different
Built for the Edge
The processing of data for many organizations is moving away from traditional large datacenters and into edge sites where the data is collected. This concept manifests itself in many ways, such as retail stores around a country each needing highly available storage to keep POS systems online. Unlike competitive solutions that have been designed “from the datacenter down”, StorMagic SvSAN has always been targeted at edge locations and SMEs.
A simple, cost-effective solution, SvSAN allows an organization to remove the complexity in their storage infrastructure, providing instead a lightweight, efficient alternative. SvSAN has been designed for the realities of edge computing such as long latencies and limited throughput which are often found in remote areas. When space, cost or network reliability are at a premium, it is the perfect solution to eliminate downtime.
Simple, Lightweight Deployment
SvSAN eliminates complexity by directly reducing the amount of hardware required to enable highly available virtualized storage. With just two nodes at each location, organizations can benefit from a virtual SAN solution that is easy to obtain, install and operate. Furthermore, SvSAN delivers genuine 2 node high availability without significant system requirements and huge flexibility. Use any x86 server hardware, any CPU, any storage type, and either vSphere, Hyper-V or KVM hypervisors. SvSAN needs just 1GB of RAM, storage of 512MB for the boot device and a 20GB journal drive, and can operate over a 1GbE network. Together, these requirements put SvSAN at a significant cost advantage to other solutions on the market – even other virtual SANs.
Tailored and Scalable
With options to deploy on two nodes for a light footprint or on three nodes for added redundancy, as well as hyperconverged and storage-only deployment models, SvSAN's flexibility ensures organizations can create an architecture that fits their precise needs. Whatever the architecture, SvSAN's centralized management enables simple, straightforward operation from a single location, no matter how many clusters are deployed. Deploy, manage and upgrade clusters without onsite visits and save money by keeping specialist IT staff at HQ, not at every remote site.
