Global Metadata

Metadata is often described as “data about data.” It is used to identify file location, file size, when they were created and by whom, among other details. It is what a file system uses to find and organize data. It is the foundation for performance in Panzura CloudFS Global Cloud File System.

The Problem With Legacy File Systems

Within an office or data center, a traditional NAS typically handles file metadata and keeps it consistent across a cluster of controllers. But what happens if a file needs to be shared with users in another office?

With a legacy file system, a file is usually copied. But now there are are two copies of the file, each with their own distinct metadata. Once that occurs you have to worry about different versions and have to reconcile differences manually to avoid losing data.

How Panzura CloudFS Uses Global Metadata

Panzura CloudFS™ consolidates enterprise data in the cloud. Every Panzura Freedom Filer in the file system has the metadata for the entire file system locally. Since every Filer has all of the metadata, every location can read any data from any location. With Panzura CloudFS there is no need to duplicate or mirror files between sites — there’s only One Global Cloud File System and One Source of Truth.

In an enterprise-grade distributed cloud file system, Global Metadata enables two key aspects to performance — local access speed and global synchronization speed.

Fast Local Access

Panzura uses flash storage for fast metadata access and caching. Flash enables the system to handle random IOPS workloads extremely quickly and to respond efficiently to sequential read requests when users try to open files. High IOPS and low latency are essential to file system performance.

Flash storage is about 100 times faster than legacy disk drives and provides up to 400 times more IOPS. So even on a traditional array, it makes sense to put metadata on flash where user requests will be served quickly. Every major enterprise storage solution uses flash for metadata and caching.

Fast Global Synchronization

If a user changes a file in one office, file metadata needs to update immediately in every other location to maintain One Global Experience for all users. Panzura patented technology keeps metadata synchronized in real time, in every Filer, in every location so enterprises can enable One Collaborative Team.
