Rational Survivability

I admit I was enticed by the title of the blog and the introductory paragraph certainly reeled me in with the author creds:

This post was written with Andrew Lambeth.  Andrew has been virtualizing networking for long enough to have coined the term “vswitch”, and led the vDS distributed switching project at VMware

I can only assume that this is the same Andrew Lambeth who is currently employed at Nicira.  I had high expectations given the title,  so I sat down, strapped in and prepared for a fire hose.

Boy did I get one…

27 paragraphs amounting to 1,601 words worth that basically concluded that server virtualization is not the same thing as network virtualization, stateful L2 & L3 network virtualization at scale is difficult and ultimately virtualizing the data plane is the easy part while the hard part of getting the mackerel out of the tin is virtualizing the control plane – statefully.*

*[These are clearly *my* words as the only thing fishy here was the conclusion…]

It seems the main point here, besides that mentioned above, is to stealthily and diligently distance Nicira as far from the description of “…could be to networking something like what VMWare was to computer servers” as possible.

This is interesting given that this is how they were described in a NY Times blog some months ago.  Indeed, this is exactly the description I could have sworn *used* to appear on Nicira’s own about page…it certainly shows up in Google searches of their partners o_O

In his last section titled “This is all interesting … but why do I care?,” I had selfishly hoped for that very answer.

Sadly, at the end of the day, Lambeth’s potentially excellent post appears more concerned about culling marketing terms than hammering home an important engineering nuance:

Perhaps the confusion is harmless, but it does seem to effect how the solution space is viewed, and that may be drawing the conversation away from what really is important, scale (lots of it) and distributed state consistency. Worrying about the datapath , is worrying about a trivial component of an otherwise enormously challenging problem

This smacks of positioning against both OpenFlow (addressed here) as well as other network virtualization startups.

Bummer.
