StarWind Virtual SAN

StarWind Virtual SAN is the product that put StarWind on the map — and post-Broadcom, it's the product sending VMware shops scrambling for alternatives. VSAN creates a fully fault-tolerant, high-performance shared storage pool by mirroring the internal disks and flash drives across your existing hypervisor servers. No external SAN. No NAS. No proprietary hardware. Just software that turns commodity servers into enterprise-grade shared storage.

The killer feature is genuine 2-node high availability without a witness. VMware vSAN requires a third witness node for a 2-node cluster — StarWind doesn't. If one node goes down, the other keeps running with zero data loss and zero interruption. That alone saves you a server and a vSAN licence. It runs directly inside the hypervisor as a lightweight service or VM, supporting VMware vSphere, Microsoft Hyper-V, Proxmox VE, and KVM. No proprietary hypervisor lock-in, no Hardware Compatibility Lists dictating what drives you can buy.

Performance is genuinely impressive for a software-defined solution. RAM-based write-back caching, in-line deduplication and compression, and support for NVMe-oF alongside traditional iSCSI, NFS, and SMB3 protocols mean you're not sacrificing speed for flexibility. For remote offices, branch offices, and edge deployments where you need shared storage but can't justify the cost of a physical SAN — or the post-Broadcom price tag on VMware vSAN — StarWind VSAN is the straightforward answer.
