Microsoft Storage Spaces Direct vs StarWind Virtual Tape Library comparison

Storage Spaces Direct uses industry-standard servers with local-attached drives to create highly available, highly scalable software-defined storage at a fraction of the cost of traditional SAN or NAS arrays. Its converged or hyper-converged architecture radically simplifies procurement and deployment, while features like caching, storage tiers, and erasure coding, together with the latest hardware innovation like RDMA networking and NVMe drives, deliver unrivaled efficiency and performance.

For SMB and Enterprises, who either look to get rid of backup tapes completely, or are willing to accelerate backup process and add an extra level of protection, our solution is StarWind Virtual Tape Library (VTL). It is an appliance that eliminates the need in physical tape and “pretends” to be a supported tape drive or autoloader, keeping all data on inexpensive, fast and high-capacity spinning disks.

Even with explosive data growth, StarWind VTL fits the backup into backup window by accelerating it, so the process does not overlap with production time. Optionally, it creates additional copy of backup data for better safety. It is also available in a software-only form, as part of StarWind VSAN functionality. 

StarWind VTL targets those, who need to replace existing tape backup infrastructure or accelerate it if regulatory requirements prohibit replacement. In case the goal is just virtualizing tape backup or creating a stretched backup infrastructure, StarWind Tape Redirector will come in handy.
