Create networked IP Storage along with your server virtual machines, all on the same hardware platform. Increase productivity, simplify management and reduce power and rack space requirements while using SCVM Virtual Storage Appliance with your existing hardware.

By creating a StoneFly iSCSI Target within a VMware or Hyper-V compatible virtual server, StoneFly customers may reallocate existing hardware resources to create an Enterprise SAN/NAS or object Storage for your Physical or virtual host servers. Use it as primary or secondary Storage as business continuity and disaster recovery solution. StoneFly synchronous mirroring within the data center and distributed campus, along with asynchronous mirroring (replication) between remote facilities and private or public cloud enables instant disaster recovery and eliminates loss of access to Storage during disasters.

Of the available data optimization technologies, data deduplication offers the greatest potential to deliver substantial and recurring impact on the cost and manageability of data growth. StoneFly’s optional deduplication technology provides optimized data deduplication for increased Storage efficiency, allowing users to fit 5x to 137x more data (depending on the data mix) within the same Storage footprint with minimal impacts to overall performance.

Other premium services for SCVM Virtual Storage Appliance installations include StoneFly’s hardware-enabled block level AES 256 volume encryption, thin provisioning with space reclamation, NAS (support for NFS and CIFS protocols), Scale Out NAS, as well as VSS support for databases such as Microsoft Exchange and SQL.

The StoneFly SCVM Virtual Storage Appliance lowers operational data-center costs and provides a quick RTO (Return to Operation) in the event of a local site failure. In essence, the StoneFly SCVM gives you the ability to create your own “DR Site in a box”.

The Scale Out NAS feature of the SSO allows you to “Scale Out” as your business grows by adding nodes. With the SSO you can expand one or more volumes across multiple nodes using no metadata database or director as a single namespace. Usable bandwidth increases as new nodes are added. Best of all, you can manage multiple nodes with just a single user interface. Each time the SSO is Scaled Out, it adds more capacity, more throughput, and more concurrency. Installation, management and scaling is simple to achieve at any size.

Content creation, transformation, production and archive, as well as unstructured data (documents, presentations, pictures, music and video files) are best stored in large Scale Out NAS appliances like the StoneFly SSO. SSO allows you to add server nodes on the fly as well as add CPU horsepower and Storage capacity. SSO simplifies the Storage of media and is the ideal platform for consolidation onto a shared resource implementing higher utilization.

SSO is often used for ultra-fast primary Storage for visual effects and high IO-intensive media production applications that require high-concurrent sequential throughput, post-production transcode and streaming media. It drives down the overall cost of Storage while increasing performance for applications that need it when they need it, and reduces costs and floor space requirements. Capacity can be quickly provisioned, shared, and managed with fewer resources. StoneFly SSO is efficient to operate since it leverages all of its resources, maximizes utilization, and integrates nearline SAS, enterprise SAS, SSD, Microsoft Azure Blobs, Amazon S3 and Glacier allows tiering within the nodes and across On-Perm and cloud storage nodes.

What is Scale Out NAS?

Scale Out NAS is a distributed file system that can Scale to theoretical unlimited petabytes all while handling thousands of clients. It functions as a distributed data overlay, polling together Storage building blocks over TCP/IP, aggregating disk resources and managing data in a single global namespace. The unified platform handles blocks, files, objects and big data.

ScaleOut NAS solves enterprise Storage requirements, including:

  • Enterprise-wide file sharing with a single access point across data Storage locations.
  • Nearline Storage for infrequently accessed data that needs to be online.
  • Rich media (audio and video) content distribution with petabyte-scale Storage and high-read performance requirements.
  • High-performance Storage for bandwidth-intensive applications like weather prediction and oil & gas exploration.
  • Centralized Storage-as-a-service to enterprise applications.
  • Backup target and archive for on-site or off-site data protection.

Scale out NAS-  Why SSO is is the Best Scale out NAS you can Purchase

Distributed File System

A file system in which data is spread over different nodes where users can access the file without knowing the actual location of the file. User doesn’t experience the feel of remote access.

Standard file format

XFS alongside Stonefly’s Scale out NAS operating system ensures full compatibility and guarantees customers access to the files with standard OS. NO Vendor dependency. 

NO Metadata - NO MetaData Director, NO Centralize Database

Any request can be handled by any node at any time by hashing the Read/Write request to calculate the file location across all the nodes. By automatically calculating the answer, Scale Out NAS avoid bottleneck and Metadata corruption and can handle a wide range of files size without affecting the performance and allowing for unlimited scalability.

High Performance

Able to deliver when properly configured Can exceed aggregate read and write speed in most use cases with files sizes at full network bandwidth of up to  3GB/Sec per Node and aggregate as more node added

Segments are partitions

Segments are partitions that files are placed for sharing between trusted storage pools.

Erasure coding (EC)

Erasure coding (EC) is a method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces and stored across a set of different locations

Volume supported

 Distributed – Striped- Distributed Sync Mirrored – Distributed Mirrored – Distributed Striped Mirrored- Dispersed – Geo-Dispersed On-Perm-Clouds and Clouds-Clouds.

Dispersed volumes

are based on erasure coding. This allows the recovery of the data stored on one or more Segments in case of failure. The number of segments s that can fail without losing data is configured by setting the redundancy count.
Dispersed volume requires less storage space when compared to a mirrored volume. It is equivalent to a mirrored pool of size two, but requires 1.5 TB instead of 2 TB to store 1 TB of data when the redundancy level is set to 2. In a dispersed volume, each segment stores some portions of data and parity or redundancy. The dispersed volume sustains the loss of data based on the redundancy level. Redundancy level of up 1 to 5 can be set in the dispersed configuration.

Tiered volume

On a tiered volume, files are tracked according to the frequency of access. More accessed files tend to migrate to faster storage and less frequently used to slower storage. The behavior can be influenced with tuning parameters.

Supports Different Protocol

CIFS, NFS   the most popular used protocols.


It provides back-ups of data for disaster recovery. Here comes the concept of master and slave volumes. So that if the master is down the whole of the data can be accessed via slave. This feature is used to sync data between geographically separated servers. Geo-replication can be done from or to On-perm to Public (Microsoft Azure, Amazon (AWS) Private Cloud and  Cloud to cloud private or public.


Provides flexibility in data backup – The Snapshot is block bases which create a point in time backup delta from the only blocks that have changed from the last snapshot. Snapshot is read-only files that help in recovery and protection against ransomware.

Network and I/O Encryption

Network encryption using TLS/SSL for authentication and authorization,

I/O encryption – encryption of the I/O connections between Clients and NA

Stackable design

Allows for agile development and deployment for a new feature for customers to enjoy.

Access Files From Any Node

Each Server client can access their files from any node. One a single IP for all the nodes. Exclusive access can be given to one or multiple clients to be serviced by one IP node.

NO or little Inter-Node traffic

NO need to high-speed interconnects and Network to purchase and maintain.

Unlimited High Availability and Redundancy

Support of Hardware Raid and Erasure coding within or across Nodes for unlimited High availability and redundancy.  Selectable redundancy failover from 1 to 5 disk per node.

Expand Volume Across Nodes

volume is a logical collection of segments. Most of the management  operations are performed on the volume such expansion. Volume can expand across nodes to create a single namespace.

Auto Re-balance

Auto Re-balance allows a distributed volume with only one segment. For instance, we create 10 files on the volume through volume. Now all the files are residing on the same segment since there is only segment in the volume. On adding one more segment to the volume, we may have to re-balance the total number of files among the two segment. If a volume is expanded or shrunk.

Distributed Volumes

This type of volume spreads files across the segments in the volume across the nodes.

Distributed Dispersed volume

There will be multiple sets of segments (sub-volumes) that stores data with erasure coding. All the files are distributed over these sets of erasure coded segments. In this scenario, even if a redundant number of segments is lost from every dispersed subvolume, there is no data loss.

Automated Tiering

Great for stable workloads, cost saving  where frequently used data fits on small, fast storage, such as SSDs and less frequently accessed  or old data resides on a slower/cheaper/remote volume, node, cloud, such as spinning disks, Hot Blob, Cool Blob(Azure), S3, Glacier (amazon)


If any of the segments in a replicated volume are down and users modify the files within the other segments, the automatic self-heal daemon will come into action as soon as the segment is up next time and the transactions occurred during the down time are synced accordingly.


Portable Operating System Interface (POSIX) is the family of standards defined by the IEEE as a solution to the compatibility between Unix-variants in the form of an Application Programmable Interface (API).e data needs to be re-balanced among the various segment included in the volume.

Cloud Cache

Build in Flash Cache feature allows some volumes to be used as a front-end cache for Public cloud storage such Microsoft Azure Blobs or S3 and Glacier from Amazon.

Cloud Cache

Build in Flash Cache feature allows some volumes be used as a front-end cache for Public cloud storage such Microsoft Azure Blobs or S3 and Glacier from Amazon.

Management encryption

Encryption of the management connections within volumes. The node and volumes can be fully dispersed between On-Per and Clouds. Support for ASE-256 at rest and transit.

Global Scale Out Storage for OpenStack – Cinder, Swift, Glance

StoneFly’s SSO “Super Scale Out” NAS Storage Appliances fully support OpenStack. StoneFly NAS can be used as global Scale Out Storage for OpenStack Block or Volume Storage (Cinder), OpenStack Container or Object Storage (Swift), as well as Storage for the OpenStack Image service (Glance).

StoneFly SSO can be used for a single type of OpenStack Storage (e.g. Cinder), or it can be used for any combination of Cinder, Swift and Glance. This is in addition to using the StoneFly SSO’s Scale Out NAS Storage for your regular physical and virtual servers or workstations.

A common limitation when using Cinder is that although volumes can be added to increase Storage, those volumes cannot be expanded. With StoneFly Scale Out NAS, volumes for Cinder Block Storage can easily be expanded by adding either bricks (drives) or additional Scale Out NAS nodes. Since volumes can be easily expanded across multiple SSO Scale Out NAS appliance nodes, the volume for OpenStack will expand readily and expansion is nearly limitless.

Key advantages of using StoneFly SSO for OpenStack shared storage:

  • Cost-effective alternative to using local Storage.
  • Increased reliability since all StoneFly Scale Out NAS nodes feature hardware RAID, redundant hot-swappable power supply modules, and you do not lose access to your data if a compute node goes down (in OpenStack environments running multiple compute nodes).
  • Makes it possible to share Storage for other purposes beyond OpenStack (NAS Storage for regular physical and virtual servers in your datacenter).
  • Ability to scale/expand and increase the performance of a particular volume since you are not limited by the number of disks in a single physical machine.
  • Management and recovery of compute nodes running Nova is much easier because you do not have to maintain their state. Since Storage is not tied to another node, compute nodes can just be restarted as a new instance.
