Intelligent File Caching & Tiering

CTERA’s smart caching technology delivers fast local access to a cloud-based global file system. Frequently used or critical files are cached locally to ensure optimal edge performance, while file changes are replicated to the cloud.

Colder data is tiered to cost-effective and scalable cloud object storage. Enterprises gain unlimited file capacity at the edge with no need for additional storage as data volumes grow.

How Intelligent File Caching Works
  • 1
    Users see global file system as a local desktop drive
  • 2
    Changes are deduped, encrypted, and bi-directionally synced with cloud
  • 3
    Non-pinned data removed locally based on LRY algorithm cache settings
Infinite, Fast Access to Cloud Files from Any Device

Unlimited File Capacity and Scalability
Secure and unlimited file access from any endpoint or edge filer.

Reduced Edge Storage
Only frequently used files are stored at the edge, while data tiering eliminates the need for truck rolls or installation of new appliances to expand capacity.

Highest Speed File Access
Office and remote user access to centralized cloud-based files with optimized file server and endpoint access.

Intelligent File Tiering
Automated tiering lets you move cold data to low-cost cloud object storage while locally caching hot files for fast access.

Global Namespace
Local presentation of cloud-based file ‘stubs’ on edge devices gives users complete access to the global file system from their laptop or workstation.

Seamless Data Migration
Easy migration of existing network file shares, access permissions, and ACLs/security policies from legacy file systems.
