Software-defined storage (SDS) is a software-centric approach to orchestrating and automating the use of direct-attached storage resources. SDS abstracts hardware storage and storage controllers into a separate layer pulled into a single pool and later available for most optimal use and distribution around the cluster. SDS puts every bit of storage to good use instead of wasting its potential.
Since it's a software-centric approach, software-defined storage, being software, decouples the underlying storage potential from directly attached storage. SDS pulls available hardware storage capacity into a unified, abstracted storage layer. This way, you can use all of your storage power as you need fit, when you need it, how you need it, and, most importantly – automate the process of storage use.
SDS is all about squeezing the maximum out of the minimum. It's shocking how much more you can do with your available storage once it's been logically abstracted and organized rather than when it's in separate siloes. SDS also enables incredible flexibility: scale up, scale out, scale down, and maintenance without downtime. Just add one storage medium element and it'll be added to the layer.
Software-defined storage solutions combine resource flexibility, programmability, and automation. IT infrastructure, with properly configured SDS in place, shows improved SLAs and QoS; increases performance, data availability, and efficiency; as well as enhances security and compliance. SDS is all about versatile and automated data management, resolving routine heaviness and ineffective hardware use.
It seems like everyone is being really hard on traditional storage. There's nothing wrong with traditional storage. However, why settle for less when you can have more for less cost?
| Traditional Storage | Software-Defined Storage | |
|---|---|---|
| Form | Hardware | Software |
| Lifecycle | Mandatory support lifecycle | Indefinite operability via updates |
| Configuration | Dedicated storage system | Works with any x86 hardware |
| Scalability | Scale-up by adding additional disk capacity | Scale-up and scale-out readily available |
| Operation | Dedicated storage administrator | Intuitive operation via web UI |
| Redundancy | Single point of failure | Includes fault tolerance and high availability features |
| Modernity | Self-service provisioning absent | Self-service provisioning and automation present |
SDS can work with both legacy storage media and storage protocols as well as modern ones. Operating on readily available commercial hardware, SDS squeezes every bit of performance potential for every cent you paid for your hardware storage and more.
What is frequently overlooked in software defined storage is its innate redundancy features. Software-defined storage vendors approach this differently but the better SDS solutions out there have solid fault tolerance potential for proper data availability.
SDS allocates much more power to all of your applications and workloads than they would get otherwise, with just storage disks attached. With software-defined storage, your systems will enjoy constant high uptime, resiliency, and flexible scalability.
With SDS, your organization will deliver consistent, qualitative services to your customers, which will favorably impact your business reputation. Also, since the consumer terrain changes rapidly, SDS will allow you to adapt to business and technological growth in a snap.
StarWind is included in Gartner® Magic Quadrant™ for HCI Software for the fourth year in a row. The report discusses the latest changes and predictions about the HCI industry, and how HCI vendors maneuver the changing terrain amidst the pandemic.
Companies quickly shift to hybrid cloud and HCI vendors to cut down IT infrastructure costs and complexity, and increase business agility. ISG explains how HCI tackles those concerns, how to choose HCI properly, and examines how good StarWind does HCI exactly.

StarWind was among the pioneers of storage virtualization as a concept and, later, among the first ones to develop and make hyperconvergence available to a wider audience. StarWind products are built around accessibility, simplicity, and maximum performance out of minimal resources. We believe SDS and hyperconvergence aren't for the private club – they are the new IT infrastructure standard for all.
SDS enables businesses to forgo building costly datacenters at ROBO locations while also avoiding downtime. Minimalistic off-the-shelf hardware can be deployed with SDS on top for high performance, easy data management, and flawless connection with HQ.
Software defined storage solutions are perfect for edge scenarios thanks to their minimum operation requirements and maximum output in operation. Whether it's tactical units, first-responders, mobile devices, extreme conditions, or smart cities – SDS can boost them all.
Cloud storage has exploded in popularity, offering a reliable and cost-efficient way for storing your data. In addition to traditional scaling, SDS can expand your storage infrastructure to the cloud, delivering even higher cost-efficiency and disaster resistance (DR) capabilities.
Software-defined storage sounds fancy and misconceptions commonly plague even experienced IT professionals. However, modern SDS has accessible pricing, practical features, and can be leveraged to excellent degrees even by the smallest of businesses today.
Software-defined infrastructure is a broad concept, which includes software-defined networking (SDN), software-defined storage (SDS), and software-defined compute (SDC) that operates as a software-defined datacenter (SDDC). Put shortly, SDI can operate all elements without the human factor, automatically, being hardware-agnostic and effectively operating heterogeneous IT environments as one.
Software-defined storage in data center constitutes an element of IT infrastructure operation. SDS is a software product deployed on top of your hypervisor of choice. It then virtualized direct-attached storage and storage controllers into a unified abstracted layer for the rest of the data center and applications to use. It seems complicated but SDS usually runs in the background and needs no babysitting.
Software defined storage market is typically categorized by several identifiers: Type (block, file, object, HCI); Enterprise Size (SME, Large Enterprise); Geographic Location; and End-User Industry (Government, BFSI, Telecommunications and IT). Software defined storage market has exploded in recent years and is predicted to grow several times more in the next few years.
Free software-defined storage refers to two things: Free SDS Version and Trial SDS Version. Usually, most software have a trial period where the user can test out all its potential for a period of time to see if they like it and want to buy it. Few SDS vendors offer free products. Free SDS is a version with restricted features, usually, available for the tiniest of business, lab, or proof of concept (PoC) scenarios.
