Quick Start Guide: Creating HA LSFS Device with StarWind Virtual SAN
This document contains detailed instructions on how to create two nodes High Availability device powered by Log-Structured File System that will run on top of two Windows Server 2012 R2 physical hosts. It is intended for experienced Windows system administrators and IT professionals who would like to configure StarWind Virtual SAN® solution.
StarWind Virtual SAN® is a native Windows hypervisor-centric hardware-less VM storage solution. It creates a fully fault tolerant VM-centric and high performing storage pool purpose built for the virtualization workloads by mirroring existing server’s storage and RAM between the participating storage cluster nodes. The mirrored storage resource is then connected to all cluster nodes treated just as local storage by both hypervisors and clustered applications. Fault tolerance is achieved by providing multipathed access to all storage nodes. StarWind Virtual SAN ® delivers supreme performance compared to any dedicated SAN solution since it runs locally on the hypervisor and all IO is processed by local RAM, SSD cache, and disks and never bottlenecked by storage fabric. Also, StarWind Virtual SAN® includes the Log-Structuring File System technology, which coalesces small random writes, typical for virtualized environment, into the stream of big sequential writes. As the result the performance is increased and the Flash life is prolonged.
The process of Creating Log-Structured File System (LSFS) Device consists of the following main sections:
- Configuring the storage pool and choosing the server
- Adding a new device using Add Device Wizard
- Configuring replication using Replication Manager
