Calculate Your Data Storage Capacity

Unlimited Data Storage Possibilities within One Software

With Open-E JovianDSS, you have unlimited options to build your data storage environment, no matter what the size or business model of your company is. You can choose between file storage (NAS), and block storage (SAN), as well as iSCSI, Fibre Channel (FC), NFS, or SMB (CIFS) and NVMe-oF protocols. The most popular virtualization systems, such as VMware, Proxmox, Citrix, or Microsoft Hyper-V, are also available.

Open-E JovianDSS is Linux-based Software-defined Storage that gives you flexibility in terms of data storage architecture. It can be set up on physical servers or as a virtual storage appliance in hyper-converged environments. It's also hardware-agnostic and provides you with much better hardware compatibility than competing products based on other operating systems.

Ensure your data availability with either the Shared High Availability Cluster or Non-Shared High Availability Cluster architectures, supported by Open-E JovianDSS, and choose the solution best tailored to your business objectives.

Open‑E JovianDSS Key Features & Benefits


Data Acceleration

With Open-E JovianDSS you can take full advantage of your data storage appliances' performance thanks to:

  • Acceleration of random writes with Write Log (ZIL)
  • Hybrid Read Cache with the first level in RAM (ARC -Adaptive Replacement Cache) and second Read Cache level on an SSD or NVMe (L2ARC)
  • High cache hit rate by using ARC's most recently used (MRU) and most frequently used (MFU) Read Cache algorithms
  • Data resilvering of used space only
  • ZFS Special Devices used to store specific types of data, such as metadata or small file blocks, on dedicated high-performance data storage devices like SSDs or NVMes

 

Data Integrity and Protection

Protection against data loss is a key challenge these days and Open-E JovianDSS is the core of your infrastructure's security thanks to:

  • Data and metadata check-summing
  • Self-healing to detect and correct silent data errors with Scrub utility
  • Atomic Transaction Writes to keep data consistent
  • Transactional copy-on-write I/O operations that eliminate silent data corruption and data fragmentation
  • Storing multiple copies of user data

 

Data Optimization

You will have the ability to save data storage space with the following
Open-E JovianDSS features:

  • Inline Compression (LZ4, LZJB, ZLE, GZIP 1..9)
  • Inline Deduplication
  • Thick, Thin and Over-Provisioning
  • Lightweight snapshots and clones taking up space once changes are made only
  • NVMe Partitioning

 

User Authentication & System Monitoring

Open-E JovianDSS enables access to both internal and external administration tools like:

  • User Authentication through Local LDAP users and groups authentication for SMB/CIFS protocol, as well as through external active domain server
  • Open-E JovianDSS System Monitoring with SNMP, Nagios or Checkmk, as well as general GUI statistics
