Hybrid cloud storage combines the security of internal data storage with the larger storage capabilities of the cloud. Many companies keep the data they access frequently on their servers located on-site, but they put back-up and inactive data on the cloud to free up space for more crucial information. Using the right hybrid cloud storage system should give the impression of only having one storage location, even though that isn’t actually the case. Hybrid cloud storage usually uses commercial storage software via cloud storage appliances.
The TwinStrata hybrid storage appliances offer a range of storage from 1 terabyte up
Nirvanix only offers NAS-only storage solutions, including hybrid cloud storage. Their maximum storage is 400 terabytes (200TB per node with each node using 2 TB SATA drives). For network connectivity, you can use GbE or 10 GbE. If you have a NAS already in place and are just looking to expand a bit with hybrid cloud storage, Nirvanix is for you, especially if you intend on returning to local storage only sometime in the future. However, if you have an especially demanding workload such as viritualization, Nirvanix is not for you.
Nasuni already handled NFS and CIFS file protocols, but they recently added iSCSI to their lineup. Each Nasuni controller has up to 12 terabytes of local disk cache, but the virtual appliance can go up to 64 terabytes. The Nasuni offers predictable performance, but you will be limited to the capacity of the device you’re using for local storage in terms of capacity. For hybrid cloud storage, Nasuni uses periodic snapshots to replicate data to the cloud. This makes sure that you always have backup as there will be no backlog of unreplicated data. Answer these questions to find out which hybrid cloud storage is right for you.
