Open-E JovianDSS is a ZFS and Linux-based data storage software designed for businesses of all sizes,
​​​​​​​especially Enterprise Software Defined Storage environments.
Open-E JovianDSS offers unlimited possibilities for architecting storage environments with iSCSI, Fibre Channel (FC) and NFS, SMB (CIFS) protocols for companies of all sizes - from small family businesses to medium-sized and large enterprises. With its Linux-based architecture, Open-E JovianDSS offers significantly better hardware compatibility than competing products based on other operating systems. Open-E JovianDSS is a perfect choice for any virtualised storage environment as it supports VMware, Citrix and Microsoft Hyper-V. It can be deployed on physical servers or as a virtual storage appliance (e.g. in hyper-converged environments).

THE MAIN FEATURES AND BENEFITS OF OPEN-E JOVIANDSS DATA STORAGE

DATA ACCELERATION

  • Acceleration of random writes with Write Log (ZIL)
  • Hybrid read cache with first level in RAM (ARC -Adaptive Replacement Cache) and second read cache level on an SSD or NVMe (L2ARC)

  • Data resilvering (recovery of the occupied storage space)
  • Compression and deduplication for improved performance

DATA AVAILABILITY

  • iSCSI, Fibre Channel (FC), NFS, SMB (CIFS)
  • Use of virtual IPs

DATA AVAILABILITY

  • High Availability Dual Controller Clustering

On- & Off-site Data Protection

The On- & Off-site Data Protection feature in Open-E JovianDSS 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.

On-site (local) backups


​​​​​​​On-site backups are kept at your place of business on the same server with additional internal drives, external drives or on other local Open-E JovianDSS-based servers. Such kind of backup is the most suitable for data protection when a company encounters ransomware attacks, hardware failure, or other disasters. Due to location, data restore is usually easier and faster than in case of an off-site backup. Therefore, it is a perfect solution for hot data which can be restored with minimized downtime or even instantly by switching to the backup copy.

Off-site (remote) backups


​​​​​​​Off-site backups are backed up to a geographically different location. Such backup secures the data in case of e.g. theft, flood, fire, power outages, etc. In case of such disasters, the data can be restored to a new primary location or, in some solutions, the backup can take the primary server's role and the data can be accessed instantly. The data transfer is secured by encryption. This kind of backup is also suitable for archiving purposes. It is also possible to set up several backup locations.

Data Recovery

  • Instant restoring from the same server
    Crucial or "hot" data can be restored instantly from one of multiple snapshots through the Snapshot Rollback function. Also, users can access the snapshot data and manually restore all selected files.
  • Data restore from a local backup server
    With a local backup server, data is available in the same location and can be recovered with a minimum amount of downtime by temporarily using a backup server as the data server while the primary server is being restored.
  • Data restore from off-site locations
    It is possible to instantly switch to the backup server and use it temporarily as a primary location (depending on the system structure) and do the restore in the background. Restoring data from an off-site server may be more time-consuming, depending on the amount of data that needs to be recovered, as well as the connection throughput.

Consistent Snapshots

A snapshot is a point-in-time copy of the source volume which can be kept on a local site. It can also be transferred to another location of a volume backup copy. Open-E JovianDSS enables creating an unlimited number of snapshots. Data from a snapshot can be instantly restored with a roll-back functionality or an additional volume (clone).

In the On- & Off-site Data Protection feature, snapshots are asynchronously replicated to local and/or remote locations according to a retention plan that can be customized specifically to individual requirements and the disaster recovery plan. Since snapshots keep only the data that have changed between subsequent snapshots, only the changes are transferred to the destination location as well.

Business Continuity

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.

Open-E JovianDSS offers dozens of options in regards to architecting High Availability environments with iSCSI, Fibre Channel (FC) and NFS, SMB (CIFS) client protocols. 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.​​​​​​​
