Solution Sheets: CTERA Caching Technology Solution Brief
Distributed caching and global namespace technologies enable infinite, high speed, secure file services from any endpoint device or branch storage gateway.
Edge Caching
Get Unlimited Capacity & High-Performance File Access
CTERA’s smart file caching technology empowers corporate edge locations with high-speed access to a global file system. CTERA Edge Filers store frequently used or critical files locally, optimizing performance, reducing latency, and ensuring seamless access across SMB and NFS shares.
The global file system enables a “gold copy” of all organizational data to be stored on a cost-effective and scalable cloud object storage. Gain unlimited file capacity at the edge with no need for additional storage when enterprise data volumes grow.

How File Caching Works in the Cloud
Get Unlimited File Capacity
Secure, unlimited file access from Edge Filers, seamlessly integrating with SMB and NFS shares while replacing legacy NAS or file servers.
Reduce Edge Storage
Only frequently used files are stored at the edge, eliminating the need for additional storage appliances and optimizing capacity utilization.
Enjoy the Highest Speed File Access
Provide office and remote users with fast access to centralized cloud-based files, supporting optimized file server access across your global infrastructure.
Manage Data Across Multiple Clouds
Seamlessly move files across clouds to meet cost efficiency or data protection requirements, while maintaining control over your data environment.
Claim Your Global Namespace
CTERA Edge Filers provide a local presentation of cloud-based file ‘stubs’ on edge devices, offering complete access to the global file system from any edge location.
Seamlessly Migrate Data
Easily migrate existing network file shares, access permissions, and ACLs/security policies from legacy file systems to CTERA’s modern infrastructure.

FAQ
How scalable is CTERA's edge caching solution?
Very scalable! Our Edge Filers range from 1TB to 256TB of local cache, supporting up to 10,000 connected users per Edge Filer, an unlimited number of Edge Filers in a single Global File System, linear performance scaling and support for multi-petabyte global namespaces.
What caching algorithms does CTERA use for optimal performance?
We employ several advanced caching algorithms such as Least Recently Used (LRU) for general cache management, predictive prefetching based on access patterns, differential sync for efficient updates of modified files and intelligent data pinning for critical files.
What are the network requirements for optimal edge caching performance?
We recommend a minimum 10 Mbps connection between edge and core, latency under 250ms for real-time sync operations, support for QoS to prioritize CTERA traffic and IPv4 and IPv6 compatibility.
What is the process for cache warm-up after a cold start or cache clear?
Here’s a breakdown of our process:
– Intelligent pre-fetching based on historical access patterns
– Priority-based caching for critical datasets
– Background warm-up to minimize impact on user operations
– Configurable warm-up policies to match specific use cases
