Nasuni cloud storage moves all-flash, disk appliances to Dell

The NF-600 edge filer for solid-state drives highlights a refresh across Nasuni's cloud hardware gateways. NF appliances are now standardized on Dell PowerEdge servers.

Cloud NAS provider Nasuni Corp. this week revamped its Nasuni Filer NF hardware line, which is now based exclusively on Dell commodity servers.

The product refresh includes a new all-flash NF-600 Nasuni cloud gateway, designed on Dell's PowerEdge R630 Rack Server. Customers can order NF-600 from Nasuni resellers and get up to 35 TB of flash cache.

Nasuni also sells a base NF-600 all-flash model, which comes with 10 commercially available 800 GB solid-state drives and a maximum of 6 TB of cache.

Nasuni has been gradually moving its appliances to Dell. New models also were rolled out for NF-200, NF-400 and NF-440 Nasuni cloud filers, all of which use spinning disk housed in Dell racks. The NF-440 provides 36 TB of cache, compared to NF-400, which comes with 8 TB, NF-200 (6 TB) and NF-60 (2 TB).

The NF-60 disk appliances complete the consolidation on Dell. New NF-60 models are based on Dell's T130 tower server, a shift from Supermicro servers.

The NF physical gateways bundle Nasuni UniFS Enterprise File Services software and sit at the edge of corporate networks. NF acts as a protocol converter between local storage and public cloud storage.

Nasuni UniFS moves entire data sets to cloud storage, caching only the most active data on the local appliance. Deltas are synced in the background to a gold copy stored securely in Amazon Web Services or Microsoft Azure public cloud storage.

Cloud gateway hardware emerged with the rise of enterprise cloud storage, but the appliance model has become heavily commoditized. Customers instead prefer a virtual controller that runs on industry-standard server racks.
