LizardFS vs StarWind Virtual SAN

LizardFS is an on-premises distributed file system that combines storage from several servers into a single namespace. Data is kept in multiple replicas across available servers, and new servers can be added without downtime; chunks move automatically to balance disk use. Erasure coding divides data into parts and parity stripes, with the maker stating that it can save up to 70% of storage capacity depending on configuration. Snapshots copy metadata while sharing data chunks until a file changes. Georeplication can copy data between data centers and lets administrators choose where data is stored. Administrators can set read and write bandwidth limits and apply soft or hard quotas for file counts and total size. Deleted files go to an administrator-visible trash bin for restoration or permanent deletion. Storage is installed on Linux, with Windows and macOS clients for cluster access. LizardFS supports NFS 3.x, NFS 4.0, and pNFS, and the maker describes using it with Elasticsearch and Logstash. Pricing is available on request; support packages include weekday or 24/7 assistance depending on tier.

StarWind Virtual SAN is software designed to replace physical shared SAN storage in SMB, ROBO, and Edge environments. It provides fault tolerance and high availability starting with two nodes, and supports iSCSI, SMB3, NFS v4.1, VVols iSCSI, NVMe over Fabrics, and iSER. Deployment options include Windows-native software in a Hyper-V partition or a Linux-based virtual machine on a chosen hypervisor. An HTML5 console is used to monitor and manage hardware and software resources. Listed reliability features include ZFS self-healing, AI-powered telemetry, and call-home systems. Supported hypervisor versions include VMware vSphere ESXi 8.0 or later, Windows Server Hyper-V 2019 or later, oVirt/OLVM/RHV 4.4 or later, Proxmox VE 9.1 or later, and XCP-ng 8.3 or later. The free edition is self- or community-supported, and its comparison lists web UI support for KVM only; paid editions list KVM, Hyper-V, and ESXi.
