Coronado V-NAS Acceleration Server

Cloud storage has numerous advantages, including embedded disaster recovery. However, these advanced backend features come at a cost; namely performance. The slower the line to the cloud, the longer data takes to process; the farther the distance to the cloud, the longer data takes to process; the farther the distance between the backend data nodes, the longer data takes to replicate. All these processes lead to a lack of performance. To overcome these challenges, BridgeSTOR created the Coronado V-NAS Acceleration Server.

The Coronado V-NAS Acceleration Server has been designed to eliminate performance issues by acting as a sophisticated edge cache. An edge cache traditionally caches HTML header content so requests are handled closer to the users, allowing for less interaction with web servers. The Coronado V-NAS Acceleration Server is “data aware” of the content sent and returned from the cloud storage and is able to cache this data in a unique manner for quick recovery.

Read Requests: Read requests sent to the Coronado V-NAS Acceleration Server will first check the local cache for the existence of the data. It the data exists, it will be read from disk and immediately returned to the Coronado V-NAS Global Access Point. If the data does not exist, the request will be sent to the cloud storage. Upon return from the cloud storage, the data will be written to the local disk cache for future requests and a positive result will be returned to the Coronado V-NAS Global Access Point. Traditionally, read requests will be in cache unless removed by the cache cleanup policy (which trims the cache by removing the least accessed data).

Write Request: Write requests sent to the Coronado V-NAS Acceleration Server first check the local cache for the existence of the data. If the data exists, the sent data will be discarded and a positive return code will be immediately returned to the Coronado V-NAS Global Access Point. If the data does not exist, the data will be written to disk and a transaction log entry will be written followed by a positive return code sent to the Coronado V-NAS Global Access Point. Background program threads will then process the transaction log, sending the new data to the cloud storage. Any transaction errors will be automatically retried.

Active/Active

A key advantage of the Coronado V-NAS Acceleration Server is that multiple Coronado V-NAS Global Access Points may share it. This saves money and disk resources as each Coronado V-NAS Global Access Point may be configured without disk and share the common disk located on the Coronado V-NAS Acceleration Server. In the unlikely event that the Acceleration Server goes down, the Coronado V-NAS Global Access Points will no longer be available to share the disk data. To overcome this, V-NAS Administrators may set up two Coronado V-NAS Acceleration Servers in a mirrored fashion. This permits the Coronado V-NAS Global Access Points to round robin read and write requests between the two mirrored servers. If one of the Coronado V-NAS Acceleration Servers fails, the V-NAS Global Access Points will send requests to the current functioning node, allowing users to maintain high availability.

Key features of the Coronado V-NAS Acceleration Server include:

  • Multiple Access Point Support: Multiple Coronado V-NAS Global Access Points may share the Coronado V-NAS Acceleration Server.
  • High Availability: Two Coronado V-NAS Acceleration Servers may be combined in a mirrored environment for high availability.
  • Fast Retrieval of Read Requests: Most read requests come directly from local storage and not from cloud storage.
  • Faster Write Requests: Write requests are written to disk and written to cloud storage in the background.
  • Local Disk Cache: Coronado V-NAS Acceleration Servers allow frequently accessed data to be kept in local disk cache for accelerated file reads and writes; reducing cloud storage access fees. An internal cache policy frequently monitors the disk cache and when the disk cache is close to being filled, will automatically remove the least accessed files. There is no charge for disk caching and the disk cache size may be defined by the Coronado V-NAS Administrator.
  • Network I/O Acceleration: Maximizes performance when using limited bandwidth.
  • ProtectedCloud™ Security: Coronado V-NAS Acceleration Servers provide XTS AES-256-bit Military Grade Encryption. Encryption is performed at the source, encrypted over the wire and stored encrypted in cloud storage. XTS encryption is a sophisticated multi-key encryption, guaranteeing two blocks of data containing the same data (i.e. two blocks of data containing all 0’s) will look different. The Coronado V-NAS Administrator creates and maintains the encryption key while the second key is generated by an internal algorithm. Both keys are never stored in the cloud storage or by BridgeSTOR. If the key is lost, BridgeSTOR is not responsible for recovering the data.
  • Web-Based GUI: An easy “set and forget” GUI is included, allowing V-NAS Administrators the ability to add bucket/blog keys, end-points and cache monitoring.
