Differentiation

StarWind Virtual SAN is simple, inexpensive and offers higher performance and more features than any alternative Software-Defined Storage platform. StarWind VSAN has a simple base configuration of just two nodes without the need for voting or quorum facilities and is exceptionally easy to operate. It reduces cost requiring less hardware: no switches, no mandatory flash, no 10GbE and fewer servers. StarWind VSAN needs only two licensed nodes to handle an infrastructure of as many nodes as needed. The basic configuration supports many features unavailable in similar solutions, such as asynchronous replication, in-line and offline deduplication, Log-Structuring, multi-tiered RAM and flash cache.

StarWind VSAN supports converged scenario and can also go hyperconverged on top of existing hypervisor servers. It runs on inexpensive commercial off-the-shelf hardware, causing no hardware lock-in. Licenses are perpetual, so they will never expire and cause additional expenses for renewal. Unlike single-purpose, open-source free software, StarWind VSAN utilizes in-house developed code, well proven worldwide and is a native Windows application, without any custom Linux/FreeBSD fork-outs. StarWind VSAN is supported by StarWind and is additionally eligible for Microsoft and VMware support services. Full differentiation of StarWind Virtual SAN against competitors can be found here.

Benefits

Exceptional Simplicity

StarWind Virtual SAN runs as a native hypervisor component or in VM, and it does not require any deep storage and network administration or UNIX management skills. A typical system administrator with minimal experience in Hyper-V, VMware or Windows can install, configure and maintain VSAN operations.

COST EFFICIENCY

StarWind Virtual SAN cuts the costs at least in half, meaning both Operational and Capital Expenditure. It eliminates the actual physical shared storage, corresponding infrastructure, associated deployment and maintenance activities. StarWind VSAN works on commodity hardware, so there’s not only less hardware to purchase and maintain, but also the required hardware is inexpensive.

Performance and Features

Performance is uncompromised by the minimalistic hardware footprint, reduced deployment and management costs. StarWind Virtual SAN brings to the table server-side flash and memory caches, log-structuring and an absolutely minimalistic I/O path. The resulting performance is unmatched by either typical virtual appliances or physical shared storage.

Data Locality

The “data locality” approach effectively maximizes the performance of the IT infrastructure by keeping compute and storage resources for every virtual machine on its physical node. This allows processing most of the I/O locally, eliminating the problem of slow data transfer through interconnect fabrics and providing lower latency.

Learn more

Grid Architecture

The “grid architecture” allows building a highly fault-tolerant cluster by connecting a number of nodes together into a single grid. Such cluster topology provides a high rate of resiliency, allowing the cluster to stay operational even after multiple nodes failure while maintaining the principle of “data locality” for ultimate performance.

Deduplication
and Compression

StarWind Virtual SAN implements VM and flash-friendly space reduction technologies such as in-line deduplication and compression. The result increases usable capacity of all-flash configurations, boosts I/O performance as more data can be pinpointed to virtually "bigger" de-duplicated caches. Also, it prolongs flash life reducing the amount of write operations.

Learn more

Scale-Up and
Scale-Out

StarWind Virtual SAN allows both Scale-Up and Scale-Out architectures. Capacity can be increased by simply throwing more capacity into the existing storage cluster node. Adding a new host with its own CPU, RAM and internal storage can scale storage capacity, I/O performance and VMs.

Learn more

Unified Storage
(Multiprotocol)

StarWind Virtual SAN uses industry-standard uplink protocols, integrating with almost all virtual environments and technologies. It exposes: SMB3 with dialect features such as SMB Direct and SMB Multichannel, NFSv4.1 and iSCSI, VVols iSCSI, NVMe over Fabrics and iSER. As a result, StarWind VSAN can merge with any virtual environments.

StarWind VVols

The integration of VMware VVols support in StarWind products makes vSphere storage management highly efficient, simple and automated. StarWind VVols allows providing VMs with fine-tuned storage policies based on pre-defined storage configurations with required performance and resiliency characteristics.

Fault Tolerance
and High Availability

Virtual SAN simply "mirrors" the actual storage and caches between the given numbers of hosts creating a fault-tolerant storage pool. It is completely up to the system administrator as to how many replicas of a particular VM or LUN are kept alive and how many active storage controllers a cluster should use.

Learn more

HyperConverged

As an extension of the hypervisor, provides both outstanding performance and unified administration using hypervisor-specific management tools. VSAN simply integrates and operates with all major virtualization platforms running on Hyper-V and Windows as a native application together with vSphere or Xen nested inside a VM. Non-virtualized clusters are also fully supported.

Learn more

Converged ("Compute and Storage separated")

StarWind Virtual SAN also runs on a dedicated set of hosts in order to create a separated storage layer. The differentiation of compute and storage layers is optimum if there is need to grow by capacity only. Typical use cases are shared storage for huge clustered SQL Server, Oracle, SAP, NoSQL deployments and an inexpensive block back-end for Scale-Out File Servers.

Learn more

Server-Side Cache

Virtual SAN reduces I/O latency and eliminates network traffic to an absolute minimum by utilizing distributed RAM and flash-based caches. As a result, it improves performance and reliability without unnecessary cost. Caches are kept coherent between multiple hosts in order that a lightning-fast write-back policy is safe and achievable with commodity hardware.

Hardware Agnostic and Commodity Hardware

StarWind Virtual SAN utilizes inexpensive commodity hardware. Our unique in-house developed software makes the most performance out of general-purpose x64 servers, MLC flash, spinning disks and Ethernet. VSAN also takes care of high-performance SAS, SLC and 3D NAND flash, as well as 10 and 25/50/100 GbE networking.

Learn more

Asynchronous Replication

Virtual SAN ensures that the mission-critical business data is replicated to a disaster recovery site, following the "3-2-1 backup rule". Replication is implemented to be asynchronous, background, deduplication, and compression-aware, as well as snapshot-based. Additionally, StarWind VSAN supports asynchronous replication to private and public cloud such as Azure.

Learn more

Snapshots and Automated Storage Tiering

StarWind Virtual SAN implements inter-node tiering technology to offload cold data such as snapshots from fast and expensive primary storage to slower but inexpensive secondary storage. The combined result allows the use of a much smaller amount of flash as primary tier with cheap spindles as a secondary tier.
