What FUSION: VFS brings together.

WHAT IT ENABLES Transparent virtual drives bring proprietary high-speed compression, deduplication, integrity, versions, and recovery into familiar Windows file workflows.

FUSION: VFS for Windows

01Add virtual drives that appear and behave within the familiar Windows file browser while Fusion manages the storage architecture underneath.

Transparent to files and applications

02Browse folders, open files, save work, and use existing applications through normal operating-system file interactions instead of learning a separate storage portal.

Proprietary compression and deduplication

03Increase effective capacity by selecting and combining advanced content-aware compression and exact deduplication algorithms according to the data and workload.

Up to 1,000 MB/s and beyond

04High-throughput read and write paths can reach 1,000 MB/s or more when the storage media, interface, host, data characteristics, and selected compression and deduplication strategy support it.

Portable provider architecture

05Keep the file experience and storage contracts stable through a provider architecture designed to connect operating-system file services without changing how applications use their data.

Storage intelligence beneath normal files

06Preserve normal files, folders, and application behavior while content identity, integrity, versions, replicas, placement, and recovery operate below the file browser.

Connected Fusion storage

07Use the same storage foundations with FUSION: Vault, FUSION: Backup, FUSION: Cloud Storage, FUSION: FTP, FUSION: Engage Mail Server, FUSION: FCA archives, and FUSION: OS.

More effective space at high speed

08Reduce repeated data and storage overhead to increase effective capacity while preserving fast access, parallel work, integrity checks, and predictable recovery.

One product experience. A platform underneath.
