Getting On The Cloud: 12 Cloud Storage Gateways

TwinStrata CloudArray From EMC
From TwinStrata, which this year was acquired by EMC, comes the TwinStrata CloudArray which combines local SAN and NAS data with on-demand cloud storage for an integrated storage, off-site backup, and disaster recovery solution. CloudArray is presented as both an iSCSI and a NAS (CIFS / NFS) device. Its local storage cache allows a partial or complete copy of data to be stored on-premise while replicating it to the cloud. Customers can either get a cloud service bundled with the CloudArray, or can integrate their choice of cloud storage service. Data is encrypted in flight and at rest using 256-bit AES encryption.
