NFS 4.1's pNFS: Big NAS performance boost
This article is part of the Storage magazine issue of Vol. 8 Num. 7 October 2009
With pNFS enforcing a standardized approach to parallel file delivery, users will see a NAS performance boost in NFS 4.1, no matter whose NAS storage they have deployed. Late last year, as Network File System (NFS) 4.1 moved from Last Call to Request for Comment status at the Internet Engineering Task Force, there was a lot of press about how Parallel NFS (pNFS), included in the protocol, would create a quantum leap in network-attached storage (NAS) performance for bandwidth-intensive applications like those used in high-performance computing (HPC) applications. NFS 4.1 represents a major step in the journey to enable NFS to better serve the throughput needs driven by ever-increasing file sizes and demanding HPC environments. While the pNFS buzz has died down, vendors are developing solutions that incorporate the standard and pNFS-supporting products will be on the market in approximately six months. The 600-plus-page Request for Comment is in the editing process and full ratification should happen soon. The Network File System ...

Our latest Storage Purchasing Intentions survey suggests that there may be a glimmer of hope for the economy based on storage managers purchase plans.
Snapshots are used to enhance backup systems and shorten RTOs and RPOs. But you need to know how snapshots can vary, and what those differences could mean to your environment.
More and more shops are archiving their email, which is good thing considering ever-escalating message traffic and stringent compliance regulations.
If you thought you knew cloud storage, think again. With scores of vendors touting internal storage clouds, we'll give you the lowdown on what makes a storage cloud "internal."

With the parallel file system pNFS now part of the NFS 4.1 protocol, NAS storage will shift into a higher gear.
There's a lot to like about cloud storage, and its benefits in terms of cost savings and convenience are attractive. But there are some residual effects you should consider.
