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
