StarWind Virtual SAN is completely software-based, hypervisor-centric solution of the shared storage problem. It creates fault-tolerant, high-performing virtual machine storage for the virtualization workload from scratch. StarWind Virtual SAN basically mirrors data between two active storage nodes, eliminating single point of failure: should one node fail, the other will take over the storage traffic and continue operating.
StarWind Virtual SAN reduces CapEx and OpEx eliminating the need for an expensive SAN, NAS, or any other physical shared storage. Its key feature is simplicity: a typical system administrator with minimal experience in Hyper-V or Windows can install, configure, and maintain StarWind VSAN operations.
StarWind Virtual SAN Features:
Hyper-Converged: Being a natural part of the hypervisor, StarWind VSAN provides outstanding performance and unified administration using hypervisor-specific management tools. It runs on all major virtualization platforms like Hyper-V, vSpehere and Xen.
Сompute and Storage Separated: Although a hyper-convergence is an industry trend now, StarWind VSAN makes it possible to differentiate compute and storage layers if there’s a need to grow by capacity only.
Log-Structured File System: StarWind Virtual SAN uses Log-Structured File System in order to eliminate the problem of I/O Blender, which exists in the VM world, without deploying expensive all-flash model.
Server-Side Cache: Virtual SAN reduces I/O latency and eliminates much of the network traffic to an absolute minimum by utilizing distributed RAM and flash-based caches, which boosts performance.
Fault Tolerance: StarWind VSAN basically mirrors storage between the given number of hosts: in case one host fails, the other one will take over the storage traffic and continue operating.
Harware Agnostic and Commodity Hardware: StarWind utilizes inexpensive commodity hardware, utilizing inexpensive x64 servers, MLC flash, spinning disks and Ethernet.
Asynchronous Replication: StarWind VSAN uses asynchronous replication to a disaster recovery site to ensure the safety of your mission-critical data. Replication is implemented to be asynchronous, background, deduplication- and compression-aware as well as snapshot-based.
Deduplication and Compression: StarWind implements VM and flash-friendly space reduction technologies, namely deduplication and compression, which results in increased usable capacity of all-flash configurations and boosted I/O performance.
Virtual Tap Library (VTL): StarWind uses fast and cost-effective spinning disks to emulate traditional physical tape drives, auto-loaders and libraries.
