VFusionOS provides unlimited options to architect storage environments with iSCSI, Fibre Channel (FC) and NFS, SMB (CIFS) protocols for companies of any size – from small family businesses through medium companies to large enterprises. The Linux-based architecture provides VFusionOS with much better hardware compatibility than competing products based on other operating systems. VFusionOS is a perfect choice for any virtualized storage environment as it supports VMware, Citrix and Microsoft Hyper-V. It can be set up on physical servers or as a virtual storage appliance (e.g. in hyper-converged environments).
The On- & Off-site Data Protection feature built in VFusionOS Data Storage Software allows users to back up and restore crucial company data in case of an unexpected disaster due to a combination of several technologies.
This backup-focused feature enables creating consistent snapshots and asynchronous snapshot replication to local and/or remote destinations. The replication tasks can be set according to the specific user requirements thanks to advanced retention plans.
On- and Off-site Data Protection is very flexible, as it covers a wide range of disaster recovery plans without the need to use additional third party tools.
Continuous availability of all data keeps business running and allows companies to maintain all operations even if critical situations or disasters appear. This is achieved with High Availability systems, which aim to provide a data storage user with the highest possible performance, reliability, availability, redundancy and efficiency by minimizing downtime periods and eliminating single points of failure.
VFusionOS offers dozens of options in regards to architecting High Availability environments. These options allow you to set up High Availability Load-Balanced Storage Clusters that ensure reliability and redundancy through failover in case of a server crash.
High Availability Cluster for SMB, NFS, iSCSI and FC Pack
VFusionOS includes failover functionality for iSCSI, FC and NFS, SMB (CIFS) enabling you to set up High Availability Load-Balanced Storage Clusters that ensure reliability and redundancy through failover in case of a server crash. By using the VFusionOS Standard HA Cluster Feature Pack, you can enable High Availability for two server nodes connected to a single storage, and one or more JBODs. It also supports SAS and FC SSD / HDD disks.
Advanced HA cluster management Pack
The HA cluster management software enables you to quickly access all features related to your cluster setup. Whether for initial configuration or re-configuration after a failover – everything is in one place and guarantees ease of use for the storage administrator.
Enabeling RDMA/NVME advanced protocols ISER, NVMEof and NFS/RDMA with clustering functionality for advanced networking and sub millisecond latency performance
PCIE fabric pack
Enables the PCIE fabric composer for nano second latency communication between up to 10 UR32 expansion shelves and VVFusion Datamax NVME advanced server.(In combination with PCIE fabric Composer hardware)
Encryption acceleration pack
Hardware assisted encryption for storage pools using AES (Advanced Encryption Standard) with key lengths of 128, 192, and 256 in the CCM and GCM operation modes. *limited to 128KB block size

Backup of everything
Copies of all kinds of data are consistent, including databases and running virtual machines with all of their applications and data.
Solved problem of backup window
Backup window is reduced to minutes, since only data changes are replicated within every interval. Additionally, the backup is offloaded from the client machine to the storage server.
Protection against Ransomware
Very frequent snapshots with instant access to all data provide a quick way to roll-back to the state before a virus attack.
Instant access to and restore of previous data versions
Old data versions can be accessed and restored quickly, since they are kept in the original form. Users can instantly start using their backed up data. Also, every user has a direct access to “Previous Versions” via SMB on MS Windows clients.
Very light backup engine
Continuous interval-based replication works in the background with insignificant influence on production. There is an option to skip virtual machine snapshots in very heavy-load timeframes in VMware environments.
Optional removal and rotation of backup media
Thanks to Pool Export and Import functionalities, users can safely remove backup media (disks), rotate with other sets, or ship to another location.
Data stream is sent via SSH for safe transfer via the Internet.
