StarWind Storage Appliance
We help organizations with existing or planned compute infrastructure meet storage performance and capacity growth requirements by providing them with high-performance and easily scalable storage, covered by 24/7 support and strict SLA. StarWind Storage Appliance easily handles fast or unpredictable data growth. It serves storage as one namespace to different consumers via different uplink protocols: iSCSI, SMB3, NFS, including the RDMA-capable iSER and SMB Direct.
Additionally, the appliance features an optional gateway to Azure public cloud, which helps to implement an effective Disaster Recovery plan or meet regulatory requirements. StarWind SA scales up by adding individual disks and flash modules, or JBODs, while adding ready controller nodes allows scaling out.
StarWind SA targets those, who need high-performance primary storage or secondary storage for backup. In case there is a whole virtualization infrastructure to build from scratch, StarWind HCA will come in handy. Otherwise, if all the required hardware is present, StarWind Virtual SAN will be enough to build a high-performance virtualization setup.

Unlike other storage vendors who use a single set of drives and dual controllers in one chassis and expose block or file protocols only, we use physically separate multiple chassis with independent sets of drives and provide unified protocol access. That's why we are better suited for geo-clustering, have higher Failure to Tolerate rate and feed storage to customer in his preferred way. Additionally, StarWind SA works the latest RDMA-supporting technologies, like iSER, SMB Direct and NVMf, allowing the building of ultra-performing storage.
Exceptional SimplicityStarWind Storage Appliance is designed to serve storage to various consumers, including different virtualization environments. It achieves this due to excellent connectivity and support of industry-standard uplink protocols. Little to no effort is required from on-site IT team to attach StarWind SA to any existing infrastructure. Besides, there is one point of support for the appliance as a whole.
Low CostStarWind Storage Appliance is a ready storage solution that costs less than all the components would, if bought separately. Also, there is less hardware to purchase and maintain, because Storage Appliance inherits StarWind VSAN feature that allows it to utilize less hardware for the same workload. Besides, general and all-flash models only include commodity components and no expensive proprietary hardware.
Performance and FeaturesStarWind Storage Appliance is built with “best-of-breed” components – industry-leading software to squeeze maximum out of top-of-the-line hardware. It can run various applications, including antivirus, backup and management on top of the storage, offloading much of the I/O from the compute cluster. In addition, StarWind SA utilizes most of the performance-related features of StarWind Virtual SAN.
StarWind Storage Appliance is purpose-built as a storage separate from the compute cluster, and yet it can offer some benefits of hyperconvergence. The Storage Appliance can run various applications on the storage platform, including antivirus, backup, management, etc. As a result, StarWind SA minimizes data path, offloads much I/O from the compute cluster to the storage, boosting performance and removing all unnecessary wire interaction and consequent performance issues. In addition, it can serve as a capacity extension for a cluster based on StarWind HyperConverged Appliance, when there is no need to scale compute power. Learn more
StarWind SA is designed for “classic” converged (compute and storage separated) scenario, segregating storage from the main platform. It interacts with consumer infrastructure (virtualization, database servers, etc.) with ease, using industry-standard uplink protocols – iSCSI, SMB3, NFS, VVOLs on iSCSI, NVMe over Fabrics, iSER, and fabrics – Ethernet, InfiniBand, SAS and SATA. Utilizing converged architecture, StarWind SA allows to scale compute and storage resources independently from each other. Learn more
Compute and storage separated architecture
StarWind SA can serve storage to various consumers, because it exposes industry-standard uplink protocols and physical connectivity. As for fabrics, StarWind SA supports the standard 1 and 10 GbE, as well as newer 25/40/50/100 GbE and InfiniBand. The protocols go as follows: SMB3 with dialect features, including RDMA-supporting SMB Direct and MPIO-utilizing SMB Multichannel, NFSv4.1and iSCSI, VVOLs on iSCSI, innovative NVMe over Fabrics and iSER. StarWind SA offers significant versatility, being able to become a part of almost any architecture or virtual environment. Learn more
StarWind Storage Appliance was created to handle database, Big Data and virtualization workload properly and avoid any performance degradation. To achieve that, it uses in-house developed technologies, such as Log-Structured File System. LSFS is designed to minimize the impact of random I/O, which dominates virtualization space. Basically, it makes small random writes into big sequential pages, getting better performance from HDD and avoiding other issues typically associated with virtualization workload. Being aware of the log-on-log issue, StarWind SA has it taken care of. Learn more
StarWind Storage Appliance keeps performance high with the help of cost-efficient and reliable distributed multi-tiered RAM and flash caching. Converged architecture implies multiple layers of caches: server-side cache on the compute layer and storage cache. The former can be provided by StarWind HyperConverged Appliance, StarWind VSAN, some OS component or third-party software. The latter resides on StarWind SA, provided by the built-in StarWind Virtual SAN. StarWind SA uses flash for level 2 caching, rerouting all write-intensive I/O to level 1, where RAM is utilized. In addition, the caches are deduplicated and kept coherent between the nodes or controllers, adding to overall space-efficiency and reliability. Learn more
StarWind SA minimizes downtime by utilizing synchronous 2-way or 3-way replication, achieving 99.99% and 99.9999% uptime respectively. It basically “mirrors” data and caches between the nodes, achieving fault-tolerance of the entire storage pool, eliminating any single point of failure and minimizing downtime. Basically, StarWind builds a “grid”, taking care of data locality and foregoing wide striping, so it’s immune to classic fault-tolerance issues. With StarWind SA, the virtual environment will withstand failure of disks and even cluster nodes without compromising uptime. Learn more
StarWind SA can scale up and out to precisely meet business requirements without unnecessary expensive overprovisioning. Adding individual disks and flash modules to the storage node will increase storage capacity, as well as adding CPU-less JBOD shelves. Adding ready controller nodes will increase capacity and performance, bringing in more usable space, more I/O paths, more cache memory, increased bandwidth, higher controller and storage redundancy level. Thus, StarWind SA ensures money savings, because it allows to spend exactly as much as needed for the current workload, without the typical overpaying for overprovisioned setups. Learn more
StarWind SA is based on commercial off-the-shelf servers and cost-efficient conventional components. There is no uber-expensive proprietary stuff utilized for primary functionality: no deduplication FPGAs, no ASICs, no modified MIPS firmware 64-bit CPUs, overpriced write-back cache NVRAM etc. The only exceptions are the special cases, where hardware firewall functionality and SAS and SATA uplinks to server are required. In addition, StarWind Storage Appliance bundles all the components together with support and costs less for consumer than they would if bought separately. Learn more
StarWind SA supports asynchronous replication and utilizes an industry-leading backup solution from Veeam, which is included in the appliance. It can replicate entire storage pools or individual objects, like virtual machines and files. Thus, it ensures the safety of stored data and minimizes the risk of data corruption in case of critical failures and disasters. StarWind SA also supports the utilization of Azure public cloud, or private cloud built with Microsoft Azure Stack, as DR site, allowing the deployment of backup to geographically-remote location without any additional troubles.

StarWind SA goes well the 3-2-1 backup rule: 3 copies of data in 2 formats and 1 on a remote site, utilizing snapshots and asynchronous replication. It also employs a principle called “inter-node tiering”, which offloads rarely-used “cold” data to inexpensive and slower secondary storage tier, preserving faster controller node for “hot” data, in other words – data which is used more often. This principle leads to better cost-efficiency, because there is no need to replicate the same hardware configuration between all the controller nodes, maintain two-way data migration path. As a result, there is less CPU usage and more IOPS for the whole storage cluster itself. Learn more
StarWind SA is efficient in conserving disk space, thanks to space reduction technologies of StarWind Virtual SAN, especially when it comes to petabytes of data and all-flash appliances, where capacity is extremely expensive. Deduplication and compression ensure better performance and capacity utilization, dramatically reducing the actual amount of data to transfer and process. Thus, StarWind Storage Appliance can cope with significantly more data than its raw capacity is. In addition to its own in-line deduplication, which is good for running VMs, StarWind SA can use third-party offline deduplication, for example – Windows built-in feature, which is less resource-critical and better for cold, rarely accessed data, like backup.

StarWind SA is built with the help of StarWind VSAN, so in order to promptly evaluate its capabilities, there is a specialized version of StarWind Virtual SAN designed to deploy from a pre-configured VMware or Hyper-V compatible VM appliance. With a suitable hardware set and the “Virtual Storage Appliance” application installed bare-metal, it is possible to emulate StarWind SA in a matter of minutes, without having to order the whole physical appliance for evaluation. Being the base of SA, StarWind VSAN provides all the features of the appliance, once installed on similar hardware. For performance tests, it is highly recommended to consult our engineers for “fine tuning” to emulate the real appliance precisely. Learn more
StarWind SA uses basically the same hardware and core software as StarWind VTL. Obviously, it is reasonable to get the latter appliance to build a virtual tape library, but in case it is necessary, StarWind SA may run the Virtual Tape Library as well. It will accelerate backup process, using SAS HDD to emulate tape hardware and sophisticated RAM and flash caching to achieve high performance. As a result, backup process fits into designated time window and doesn’t overlap with production time and cause performance degradation. Learn more
