In this topography Panzura Cloud Controllers are used as unmanaged file servers of user home directories. The authoritative copy is maintained on the back end storage in the central data center.The 3% of actively used data is also stored on the Panzura CC, and users mount it with NFS or CIFS.This provides very fast unmanaged file service for remote locations. Changed data is mirrored to all othe Panzura CCs, stored at the IT center, and/or can be stored at a Cloud site.Panzura can also be used as a high throughput pipe to your internal Archive/DR site, handling deduplication, compression, and encryption. Panzura archives can be read at any time because they are stored as files.
Panzura ACC is perfect for cloud and distributed environmentsThe meta data which consists of filenames, directory names, author, security, dates, and most importantly, the global block deduplication dictionary is kept separate from the data itself. The meta data and the data are snashotted separately and sent (main and incrementals) to various locations. The meta data is always snapped and sent to all Panzura ACCs. The data may optionally be kept in a separate internal/external cloud. Thanks to the small amount of meta data that needs to be transferred, it enables all nodes to always have a complete view of the Enterprise data for browsing and searching.The Panzura Application Cloud Controller (ACC) also “owns” the data which enables it to know where the authoritative copy is located – in the cloud or in a specific controller if the write has not been synchronized with the final repository yet. Only the “delta” in the data is exchanged across controllers making it a very powerful replication solution. For example, if someone changes words in a 10MB powerpoint, only the text changes will be communicated to the controllers to make sure that they have the latest copy.Because the global deduplication dictionary is maintained everywhere, if a user were to upload a 2GB windows7.iso in San Francisco and another user in Tokyo uploaded windows7_w_sp1.iso, the upload in Tokyo will be uploading the meta data (very small, few KB max) and then the difference between window7.iso and windows7_w_sp1.iso which is much less than 2GB. The Panzura ACC has a patent pending global deduplication technology. The implementation currently has a 7% overhead, so if the difference between window7.iso and windows7_w_sp1.iso was 100GB, the resulting diff will generally be at most 107GB.All the data stored in the cloud is encrypted and the keys are stored at the customer’s premise, no Panzura device is needed in the cloud, securing the data even if a disk is thrown away at the cloud vendor’s site. There is no risk for the Enterprise of a breach in the security of its data making it more secure than local storage. This is relevant with an internal or external cloud. For external cloud, the need to not expose keys is obvious. But even in internal clouds, but not keeping keys there, the security requirements to create and maintain such internal cloud results in a lower TCO and allows enterprises to mimic external cloud storage architectures for their buildout instead of creating a new one with specific security features.
