TwinStrata Inc. has designed data migration functions into its CloudArray gateway based on lessons learned from...
the Nirvanix shutdown.
TwinStrata CloudArray stores frequently accessed data in a local storage cache and moves other data to a public cloud.
Recent updates to CloudArray include the ability to migrate data volumes across cloud providers, making it easier for customers to change or add cloud providers. Customers can migrate from one provider to another without using their own network bandwidth.
These new capabilities were developed after cloud storage provider Nirvanix shut down last fall, leaving customers to find a way to move their data to another cloud or bring it on-premises with just a few weeks' notice.
"TwinStrata worked with a major cloud provider to set up big pipelines to move data from A to B [during the Nirvanix shutdown]," said Terri McClure, a senior analyst at Milford, Mass.-based Enterprise Strategy Group (ESG). "So instead of moving data through the TwinStrata gateway, they just piped it from Nirvanix to another cloud provider."
TwinStrata CEO Nicos Vekiarides said cloud migration improvements were added to CloudArray because "it's something we learned from the Nirvanix closure."
TwinStrata now gives customers two options for data migration. One way is to pull data from the cloud and push it to another provider via a controller or gateway. "The other is cloud-to-cloud migration," Vekiarides said. "You're using the cloud provider's bandwidth. That's faster and more efficient."
A new cache migration capability moves local copies on TwinStrata's CloudArray gateway quickly to another cloud provider. This capability is helpful for small data volumes that can be moved at fast network speeds with the touch of a button.
"If you have a large percentage of data in the local cache, this is the way to go," ESG's McClure said. "This way, if your provider goes out of business or changes pricing, you just create a new storage pool and move it to another cloud."
Last week, TwinStrata added NFS support to CloudArray to go with its previous iSCSI and CIFS support; in addition, the company added the ability to access files stored on a CloudArray from any of a customer's sites through a distributed CloudArray infrastructure.
