Comparing Embrane and Nicira Is Pointless – They Are Different

Had a few conversations, and some articles, where comparisons are being made between Embrane and Nicira and wanted to point out that there are few similarities between these companies.

Predicting What Will Not Be Big in 2012

I’ve been working on making some predictions about 2012 and networking. I like to do this in the year of 2012 (not 2011 like everyone else) and I like to go further than anyone else and predict what WILL NOT be big in 2012.

VRRP. CARP. Open Standards and Royalties on LC Connectors

In which I look at CARP vs VRRP, the nature of open standards and closed source fibre optic connectors that you pay royalties on, but you probably don’t know about.

Responding: On Optimizing Traffic for Network Virtualization

I’m responding to Brad Hedlund’s post “On optimizing traffic for network virtualization” where he seems to missed a key point. It’s about cost of ownership in terms of ability to troubleshoot.

Rant: Who Is Cisco’s Customer ? Me or the Reseller ?

I resent the fact that Cisco partners get more information than Customers on Cisco’s website. Shows you who Cisco thinks the Customer really is.

What special powers do resellers have that makes them more effective ?

How does withholding information from Customers give a better outcome ?

Me ? Many resellers are not competent enough to be business and need a headstart to be useful to customers. Without some sort of “special needs” assistance, they wouldn’t be in the race.

Too harsh ? IBM and HP don’t rely on resellers to win business. Why does Cisco ?

VMware: Let’s Get Logical – The Case for OpenFlow Network Virtualization (and Their Failed Network Plans)

VMware has made several strategic moves to implement dynamic networking – vSwitch, vDS, Nexus 1000 (in partnership with Cisco), vCloud External Networks (using MAC in MAC of all things) and have basically failed to deliver overlay technology without implementing technology in the network itself. Equally, VMware hasn’t been willing to engage with the networking vendors to develop technologies that would solve this problem – VNtag / VEPA/ VEP combined with TRILL / SPBB, instead letting them argue amongst themselves. VMware attempt with vCloud networking using MACinMAC encapsulation seems to have failed and stalled and is getting another attempt using MACinIP. VMware/Xen/HyperV are all desperate to have a more dynamic network that can be controlled from their software and this might be where OpenFlow gets a big lift – as a configuration engine.

Blessay: Comparing Merchant and Custom Silicon

Merchant Silicon is an marketing term used to describe the use of “off the shelf” chip components to create a networking product and commonly used by company that design their own silicon chips when explaining that their process is better and more efficient.

The networking industry has two types of silicon: ìcustom or in houseî or ìmerchant or off the shelfî. The ‘in house silicon’ argument goes something like this :

We have our specialist engineers who can custom design an ASIC and supporting chips that are completely focussed on the features needed to deliver Product X. As a result, our designs are purposefully built to be faster, better etc. Our prices are more expensive because our products are faster and more focussed and because our costs are higher.

The ‘merchant silicon’ argument goes something like this:

The levels of expertise required to design and build a silicon chip is very high. It requires specific skills, tools, and high levels of expertise. If your core business is producing a networking device, then having your own silicon development is not core business. By relying on companies who specialise in silicon design and manufacture, we can focus on software and integration to deliver new and better features at a cheaper price.

Backplane Ethernet – The GBaseK Standard

A lesser known standard is Backplane Ethernet. I wasn’t aware of it until I was researching Notes on Cables and Connectors for 40 and 100 Gigabit Ethernet. I spent some time over the weekend scratching an itch to have a look at it and why it exists.These are scrach notes, and observations from a research session and not intended to a canonical investigation. Interesting though because it’s is valuable to understand that many network products are functionally all the same – only the software and the people are different.
