Cloud Storage Acceleration

One of the key advantages of Cloud Storage is the ability to access Cloud buckets from any location around the globe. However, this causes a particular problem for most cloud products – slow communication lines and distance being the chief culprits. BridgeSTOR has developed technology that sends data fast and efficiently into the Cloud.


Writing files to Cloud Storage is a time consuming process. For backup applications, this may not be an issue but when you have users waiting for uploads it becomes very costly to the company. BridgeSTOR products use disk caches to help reduce the user experience. The Coronado Gateway uses a Ingest cache and the Brooklyn Edge Cache uses two caches. One for metadata and one for files.

Once the data is on cache, it can been efficiently moved to the cloud while the user is off doing something else. BridgeSTOR processes file to object conversion with background threads. Once files are closed, then the background threads will move the file to the Cloud Storage while a copy of the file remains in the cache for future reads.

The Brooklyn Edge cache has been built in hierarchical storage management (HSM) system. It has been designed around an 80/60 policy. When the system cache reaches 80% the oldest accessed files in the system will be removed until the system reaches 60%. If a file is than required and is not in the cache, the file will be moved from the Cloud back into the cache and then returned to the user.
