NuView says the software also provides data replication as well as automatic failover between NetApp or Windows-based NAS devices, even if they're in different locations.
However, one major NAS platform NuView doesn't yet support is EMC Corp.'s (NYSE: EMC) Celerra, which is typically found in high-end, EMC-oriented environments. This is supposedly in the works: According to EMC's Website, NuView is integrating StorageX with Symmetrix and Celerra. But there's no word on when this feature will be available.
NuView's closest competitor, says Kerns, is Veritas Software Corp. (Nasdaq: VRTS), which provides its VxFS file system and Volume Manager for multiple server platforms. However, he notes, Veritas's solution requires installing the software on every host.
Mehta says NuView doesn't act as a file system replacement, which is the case with global file systems like IBM Corp.'s (NYSE: IBM) Storage Tank or next-generation NAS systems like those from Spinnaker Networks Inc. or Zambeel Inc. Rather, StorageX provides a unified namespace in front of existing NAS resources.
"It has taken NetApp 10 years to create and perfect its file system," he says. "These are very, very complex technologies." On the other hand, developers of those other next-generation NAS architectures argue that they're able to provide much greater scaleability by controlling the file system as well as the namespace.
