Value propositions

Our StarWind Virtual Tape Library (VTL) solution is designed for SMBs and businesses that want to either completely eliminate backup tapes or speed up backup operations and set up an additional security layer. It is a product that eliminates the need for physical tapes, simulating a supporting tape driver or autoloader so that all data is stored on low-cost, fast and high-capacity hard drives.

Even with exponential data growth, StarWind VTL adapts the backup to the backup timeframe by accelerating, so that the process does not overlap with the production time. The product creates an additional copy of the backup data for greater security. It is also available as part of the functionality of StarWind VSAN only in software form.

Backup is performed on high-speed HDD, then stored in the background on tape


In comparison to similar solutions like Software-Defined Storage, ours is generally easier to manage, more affordable and offers higher performance as well as more features. StarWind VSAN is easy to set up with two knots with no tuning or quorum options and is exceptionally user-friendly. Less hardware reduces costs: no switches, no flash required, no 10 GbE and fewer servers. StarWind VSAN requires only two licensed nodes to process an infrastructure of any number of nodes. Basic configuration supports many features that are not available in most solutions, such as asynchronous replication, deduplication in-line and offline, log structuring, multi-tiered RAM and flash cache, etc

Unlike traditional hardware storage applications, our solution is not hardware-bound, easier to use, more cost-effective and performs better. StarWind VSAN supports convergent scenarios and can also stand hyper-convergent on existing hypervisor servers. The product runs on inexpensive, commercial trading hardware from the nearest PC store, so there is no hardware dependency. The licenses are perpetual, so that they never expire and do not cause any additional expenses in the long run. StarWind VSAN includes numerous technologies for processing virtualization loads with maximum efficiency: deduplication in-line and offline, log structuring, multi-tiered RAM and flash cache, etc.

Contrary to other similar solutions, our code has been completely developed internally, for each function included. It is a simple Windows application and a proven, reliable production platform. StarWind VSAN is supported by StarWind and also applies to support for Microsoft and VMware. 


Outstanding simplicity

Simplicity is a key element. StarWind Virtual SAN runs as hypervisor components or in a VM, it does not require deep storage and network administration or UNIX management capabilities. An ordinary system administrator with minimal experience with Hyper-V, VMware or Windows can install, configure and maintain VSAN products.

Low cost

StarWind Virtual SAN reduces costs by at least half, which includes both acquisition and operating costs. Physically shared storage, appropriate infrastructure, deployment and maintenance activities are no longer necessary. StarWind VSAN works on commercial components, so not only is there less hardware to buy and maintain, but the required hardware is also cost-effective.

High performance

Performance is not affected by the minimal hardware footprint, reduced utilization and low administration costs. StarWind Virtual SAN offers server-side flash and storage caches, log structuring and an absout minimal I/O path. The performance that emerges is similar to that of a typical virtual application or physically shared memory.



Virtual SAN is a natural part of the hypervisor. This results in both outstanding performance and unified management with hypervisor-specific management tools. VSAN works with all common virtualization platforms on Hyper-V and Windows as a separate application and on vSphere or Xen within a VM. Non-virtualized clusters are typically used for performance-intensive SQL servers and Exchange installations are also fully supported.

Hyper-Convergent Architecture

Convergent (separate Computer and Memory)

StarWind Virtual SAN can also work on a dedicated Hostset that creates a separate storage layer for customers. Although a hyper-convergent scenario is currently an industry trend, there are different calculation as well as storage layers that make sense if only the capacity is to be increased. Typical applications include shared storage for large collections in SQL Server, Oracle, SAP, NoSQL deployments and cost-effective back-end for scale-out file servers.

Architecture with separate computation and memory

United Memory (Multiprotocol)

StarWind Virtual SAN uses industry standard communication protocols that work with almost all virtual environments and technologies. It includes SMB3 with dialect features such as SMB Direct and SMB Multichannel, NFSv4.1 and iSCSI, including VVols on iSCSI, NVMe over Fabrics and soon iSER. Therefore StarWind Virtual SAN is able to adapt to every virtual environment for every customer and offer unlimited usage scenarios. Typical are: pure metal, convergent (calculation and storage resources separated), hyper convergent, clustered shared volumes for SOFS, VVols over iSCSI, SMB3 file servers, etc.

VM-centric storage and StarWind Log Structured File System (LSFS)

Virtual SAN provides and manages storage with the appropriate VM workload. Multiple memory arrays are often the best solutions for hypervisors. VSAN uses a log-structured file system and powerful caches to avoid the largest possible random I/O of the dominant VM world, without using extremely expensive and cost-inefficient All Flash models.

Server-side Cache

Virtual SAN reduces I/O latency and eliminates much of the network traffic to an absolute minimum by using distributed RAM and flash caches. Performance is significantly improved. Caches remain coherent between multiple hosts, making lightning-speed writing secure and possible with commercial hardware.

Fault-tolerance and high availability

Virtual SAN mirrors the current storage and caches between the specified number of hosts and creates a fault-tolerant storage pool. The system administrator decides how many replica of a particular VM or LUN should remain active and how many active storage controllers a cluster should use. Individual disks, memory modules, entire calculation and memory hosts can fail, but runtime is never reduced.

Scale-Up and Scale-Out

StarWind Virtual SAN flexibly adapts to both scale-up and scale-out architectures. The capacity can be expanded by more hard disks in the existing storage cluster node. Adding a new host to your CPU, RAM, and internal memory can increase memory capacity, I/O performance, and number of VMs.

Hardware Agnostic and commercial hardware

StarWind Virtual SAN uses low-cost trading hardware. The core functions are provided by the in-house developed software and multi-purpose x64 server, MLC flash, hard disks and Ethernet. VSAN definitely provides high-performance SAS, more reliable SLC flash and a faster 10 and 25/50/100 GbE network, but this state-of-the-art equipment is of course completely optional. If customers don't have time to experiment, StarWind offers excellently configured, ready-to-use nodes, the StarWind HCA. They are pre-assembled on state-of-the-art trading hardware, tested by StarWind engineers and are shipped as ready-to-use products.

Asynchronous replication

Virtual SAN provides an effective mechanism to ensure the replication of critical business data at a disaster recovery site according to the 3-2-1 backup rule. Replication is performed asynchronously, in the background, with deduplication and compression, and on snapshots. Primary I/O operations do not suffer from lean resources or WAN channel requirements. StarWind also enables the use of public or private cloud services as a remote location for asynchronous replication. In addition, StarWind VSAN supports asynchronous replication on private or public cloud services such as Azure. With geo-clustering enabled, Azure can serve as a stable remote location for disaster recovery.

Snapshots and Automatic Storage Tiering

StarWind Virtual SAN includes inter-node tiering technology to download cold data such as snapshots from the fast and expensive primary storage to the slower but more affordable secondary storage. The combined result allows you to use a much smaller flash volume as a primary-tier with affordable hard drives as a secondary-tier.

Deduplication and compression

StarWind Virtual SAN includes VM and flash-friendly storage reduction technologies such as in-line deduplication and compression. As a result, the usable capacity of flash configurations increases, I/O performance increases as more data can now be allocated to virtually larger deduplicated caches, and this also increases the lifetime of the flash, as the number of writing processes is significantly reduced.

Virtual Storage Appliance

The special version of StarWind Virtual SAN is instantly installed by a pre-configured VMware and Hyper-V compatible VM application on existing hardware, automatically shared with hypervisor without manual adjustments. This does not require the expertise of an IT team. This version is ready for testing, but since it is VM-based, StarWind engineers will do some more experimentation to make a clearer performance evaluation.

Virtual Tape Library (VTL)

StarWind VSAN enables the use of high-speed hard drives to simulate traditional physical tape drives, auto-loaders and libraries. The need for this technology lies in the fact that tape backups are very critical, cost-effective and created for long-term data protection. Many companies have regulations that require company data to be kept under lock and key. Virtual Tape Library allows seamless integration into an existing backup infrastructure without breaking it down. The Disk-on-Disk-on-Tape backup offers a shorter backup period compared to traditional Disk-on-Tape scenarios and provides higher reliability because a temporary copy of the backup data is stored in a separate location, i.e. on a hard disk.
