On- and Off-site Data Protection

Open-E JovianDSS combines several technologies to create the On- and Off-site Data Protection feature - a strategy for Backup and Disaster Recovery that allows an instant restore of crucial company data in case of an unexpected disaster. It enables consistent Snapshots for virtual machines and asynchronous replication to local or remote destinations. The rotational Snapshots are stored according to a retention-interval plan for flexible backup that can be customized to specific user needs. Additionally, Open-E JovianDSS with On- and Off-site Data Protection does not require any backup agent.

• Easy-to-use, efficient backups of mission-critical data

• Scalability and ability to store backups on separate servers onand off-site to ensure maximum data security

• Optional instant disaster recovery with unparalleled flexibility – restore from 5 minutes ago or 2 years in the past if needed

• Provides data security and ensures Business Continuity in combination with a High Availability Cluster

Advanced Metro HA Cluster

Open-E JovianDSS 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 Open-E JovianDSS Advanced Metro High Availability Cluster Feature Pack, you can create High Availability for two server nodes with storage mirror over Ethernet using a storage system at each location (Dual Storage). Since the connection of cluster communication and data mirroring between nodes works over Ethernet, the nodes might be located far from each other as a (stretched) metro storage cluster. It can be 50 miles (80 km) in case of point to point fibre optic connection, or even more when using an additional switch between nodes - provided that network latency will not exceed 5ms. The Feature Pack also supports configurations of the Open-E JovianDSS Standard HA Cluster Feature Pack.

• 1Gbps, 10Gbps, 40Gbps, 100Gbps Ethernet support for maximum speed
• Perfect for both rack (from 12” / 30cm) and metro (up to 50 miles / 80km) clusters
• Allows use of less expensive SATA drives
• Easy to configure and manage
• Compared to SAS or FibreChannel, JBODs are not required
• Optional use of RAID controllers

Storage and Backup for Virtual Environments

Combined with VMware vSphere ESXi, Open-E JovianDSS is a cost-effective, flexible and scalable solution for virtualization that offers highest performance and data efficiency. The Open-E JovianDSS storage appliance can be provided as a physical data storage server or a Storage Virtual Appliance, accessed via the iSCSI or NFS protocol. Additionally, the storage has a built-in native backup and recovery functionality. The compatibility is confirmed through the “VMware Ready for Storage” certification, including the products ESXi 6.5, 6.0 U3, 6.0 U2 and 6.0 U1, 5.5. The software also contains built-in VMware Tools, including VMware storage and network drivers.

• Storage appliance can be implemented either as a physical or as a virtual server
• Built-in functionality for creating and restoring backup copies on virtual machines
• Fast implementation and ease of use – installed as a storage for ESXi within minutes
• VMware Ready
TM Storage certification
• Inexpensive, capacity-based product licenses and technical support options
• Accepted solution on the market – 95% of Open-E’s customers use our software for virtualization with VMware

Storage and Backup for Virtual Environments

Hyper-converged Storage Environments

Hyper-convergence is a software-defined way of storage management which combines storage, networking, compute, and virtualization technologies in only one physical unit. Hyper-converged environments with Open-E JovianDSS, used as a Storage Virtual Appliance (SVA), provide administrators with an integrated solution, including a cluster with one or more JBODs attached. This results in high performance, High Availability, and reliability for Enterprise setups as the HA cluster environment balances the load, and ensures uninterrupted service with failover in case one node fails. Due to only one required set of hardware per location such a solution is cost-effective and can be flexibly scaled when requirements grow.

• Reduced amount of total hardware - instead of four physical servers, only two are necessary to create an HA cluster
• Option to use commodity hardware which drastically reduces investment costs
• Easy to use interface and high performance through Software Defined Storage
• Flexibility and agility in virtualized environments with VMware or other hypervisors
• Cost-effectiveness and scalability
