FusionOS 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 FusionOS with much better hardware compatibility than competing products based on other operating systems. FusionOS 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).
FusionOS key data storage features and benefits
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)
- High cache hit rate by using ARC’s most recently used (MRU) and most frequently used (MFU) Read Cache algorithms
- Data resilvering (rebuilding of used space)
- Compression and Deduplication for improved performance
Data Accessibility
- iSCSI,Fibre Channel (FC), NFS, SMB (CIFS)
- Use of Virtual IPs
Data Availability
- High-Availability Dual-Controller Clustering
- Active-Active and Active-Passive HA Cluster
- Dual Storage (Stretched) Metro HA Cluster and Common Storage Cluster architectures
Data Integrity and Protection
- 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 eliminate silent data corruption and data fragmentation
- Storing multiple copies of user data
Data Optimization
