Today, I get to introduce my first guest blogger, Matthew O’Keefe, PhD. My colleague Matt will discuss hardware accelerating the various components of NAS systems, specifically Hitachi NAS (HNAS, aka BlueArc Mercury), in a multi-part series. Matt’s expertise is in scale-out file systems and kernel development, so you might want to read this thoroughly. Since I am a performance nut (as well as having a passion for efficiency) this post seems appropriate to provide you with some insight on the thinking and architecture within the design of HNAS.

Per my previous post, I wanted to provide more concrete examples from the storage world related to the sedimentary hypothesis.
Here goes example number one: NAS virtualization.
You may recall past companies and products in this space. Those that come immediately to mind include Rainfinity, Acopia, and StorageX, with only Acopia ARX really existing at F5 as a standalone NAS virtualization product. All the others have either been acquired or have gone out of business (at least as far as I know). As there are no longer being highlighted via a standalone application or appliance begs the question: Is NAS virtualization a viable technology?
You bet, and you can see it in action within two Hitachi products, except not as separate appliances: Notably, you’ll find NAS virtualization in the Hitachi Data Ingestor (HDI) and the Hitachi NAS Platform (HNAS).
