Intelligent Software Defined Storage

Nexfs from Nexustorage can significantly reduce data risk and costs through united block, file, cloud and object storage technology.

Non-Unified storage technologies each have their own benefits and drawbacks, often requiring IT to make a selection based on lest evil or closet matching, this results in technology implemented that does not best fit the use case, increasing storage costs, and complexity.    


Existing solutions attempt to bridge the gap in storage technologies. Many then fail in the field. Other solutions add cost, complexity, and risk while introducing some of the least favourable aspects of one technology into another.

Nexfs is different; instead of attempting to merely bridge-the-gap, Nexfs unites traditional block, file, cloud and object storage technologies, presenting a single feature-rich pool of storage. Nexfs delivers a unified smart, cost-effective and massively scalable storage solution.

As software-defined storage Nexfs offers flexibility, including the ability to configure and deploy storage systems your way; you choose the type of hardware, be that physical, virtual, cloud, or hybrid.

Nexfs allows the flexibility to deploy on any cost-effective industry-standard x86 server and disk hardware to meet required performance, durability, and availability requirements.

 If there is no budget for new hardware, IT can utilize existing hardware rather than buy new hardware to add capacity, extending the life of existing storage assets.

Software-Defined Storage helps avoid hardware lock-in and lowers the total cost of ownership compared with overpriced traditional storage appliances.

Data Placement.png

Existing storage systems tend to either move an entire file to cloud or object storage or to store file blocks as separate objects or cloud files.

Those methods are slow and cumbersome and result in unhappy storage users and administrators, additionally often third party systems are often utilised as the "go-between" to move data between traditional and object storage, adding an extra layer of expense, complexity, latency, and risk. 

Intelligent data placement is a core functionality of Nexfs,  there is no longer a need for any middle man or for users to experience slow file migrations.

Nexfs supports up to three storage tiers.

With the hottest data located on the highest performance tier, inactive data is relocated to cost-effective object or cloud storage.

Non written data blocks are thin provisioned; that is, they do not consume physical storage or incur any storage cost.

Nexfs supports up to three storage tiers. With the hottest data located on the highest performance tier, inactive data is relocated to cost-effective object or cloud storage.


Non written data blocks are thin provisioned; they do not consume physical storage or incur any storage cost. Optionally, Warm data can reside on a second storage tier. 

Nexfs data migrations are transparent, occurring in the background,  yielding the best performance to cost ratio for a file's data. No longer should the lifecycle of a file be limited in its entirety.  

Nexustorage understands the value of data to any organisation. When a file is accessed is not the primary measure of information value.


Although a file's data may not be frequently accessed, we recognize that it does not mean the information it contains has less value to a business.


The access profile of files data designates the most beneficial storage cost for that data. With Nexus, data not actively accessed resides on secure and readily available reduced-cost Object or Cloud storage.

Tiered Storage Pool.png

Nexfs presents a single intelligent pool of storage, combining the benefits of Traditional Block, Cloud, and Object Storage.

No other third party tiering software is required to sit as the go-between your block and cloud or object storage; with Nexfs this technology is entrenched deep within its core.

By self-managing the different storage tiers, Nexfs places variable-sized chunks of file data on different performing tiers of storage; unlike other solutions, files no longer have to reside entirely on a single storage tier. 

Nexfs only retrieves or updates any bits of data requested or updated in performing file operations. This technology with Nexassert allows massive multi Terabyte sized files to be stored in the cloud or object storage and then treated as though they resided on traditional block storage.

Nexfs intelligently places parts of files on the most cost-effective available storage performance matching demanded performance!

Windows Example Tiering Saving Primary S

No longer does a large amount of data need to hog your expensive high preforming SSD storage when only a small amount of the data is in use!

There is no longer a long delay in serving the first requested byte of a large file residing in Cloud or Object Storage!


No longer does the whole file need to be demigrated to tier-1 storage when only a small part of it needs updating!  


Nexassert (Patent Pending) removes the Achilles-Heel of many existing solutions allowing Nexfs to directly locate and access data belonging to a single file that resides on different storage classes without maintaining a separate index or manifest.

Those location indexes have introduced not only an unnecessary risk of data loss, they are also a big performance bottleneck. Nexassert removes that risk and the associated performance bottleneck.

Have you heard that you can't run a block-style workload with Object and Cloud storage?


Well, that is what many storage vendors would like you to believe. Why?  They can't make it work. They designed their storage systems without consideration for block-on-object, and without a significant and expensive redesign to modernize their technology for them, it will not work.

At Nexustorage set out to create a system that embraced block and object within its core; moreover, it was the first workload that we tested and demo'd.


With Nexfs, you can Store, Run, Clone, Archive VMs, and many other block workloads within your choice compatible S3 Cloud and Object storage.

Nexfs provides an underlying filesystem, which can be presented using common software and methods over multiple standard file and block protocols and the S3 Object API.

Supported protocols  include:

  • Block:    iSCSI

  • File: SMB/CIFS, NFS v3/4

  • Object/Cloud: S3 API 

Free Standard Edition.png

Unlike many of today's storage vendors, we want to get our software into your hands. We want our software to be freely available, offering real value to everyone, not only those who will benefit us financially.

Free does not mean unreliable or untrustworthy; in fact, quite the opposite; it represents our confidence in our product and the value it offers.

No more limited-time evaluation licenses, demo access to pre-configured limited access systems, no more pre-evaluation plans, and no more salespeople harassing you daily. Download our software, play with it, use it in production, ask questions; our standard edition is free after all.

While the software is free, it does not mean we don't stand behind it. And while we cannot provide free commercial support, keep watching this space; we will soon offer options for subscription-based SLA backed support as well.
