Vendors keep telling me that every business is different and customer have different needs. We all buy the same products from the same companies, use the same deployment methodologies and best practices, have the same problems and deliver the same results to the business. You aren’t a precious snowflake.
Containers virtualize at the operating system level, Hypervisors virtualize at the hardware level. Hypervisors abstract the operating system from hardware, containers abstract the application from the […]
Notes on the CheckPoint firewall clustering solution based on a review of the documentation in August 2014.
VMware announced the vCloud Hosted Services a while back and it was mostly known as vCheese for short. This week it was rebranded as “vCloud Air Network” and that is too much of a mouthful to keep saying as well. Don’t these marketing people live in the real world ? Lets me share my suggestion …….
I’ve been reading the Cisco Application Centric Infrastructure Design Guide. Sometimes I see a product of genius and wondrous use of technology, other times I’m like ‘did they do it the hard way or what’ ?
I’ve made my own handwritten font for those moments when you are “sketching” network diagrams and it is free for you to use.
Cisco announced another 6000 job cuts in the Q4 2014 Results announcement yesterday in addition to the 5000 job cuts announced last quarter. Cisco has (or had) approx. 75000 employes so that’s a lot of jobs (more than 20%) in a short period of time and this leaves me pondering the impact to the products […]
Huawei is showing some signs of maturity in the Enterprise market with this Learning website offering free e-learning courses. Unfortunately, it’s seriously restricted to partners or some other weird criteria for membership. Entitlement E-Learning courses currently face to the following types of users: Huawei channel partners; Huawei Authorized Learning Partner(HALP) and the one who passed […]
I’m often told that the enterprise customer will take years to implement Private Clouds because the enterprise is slow to adopt new technologies. Yet the private cloud is happening faster than seems practical and there has to be a reason that is driving adoption so quickly. It’s simple, point to the success of others and use that as proof of success and use that to generate permission to implement change.
I collect data from three different research . This is much higher and sooner than my previous survey data in December 2013 and more recently for InformationWeek. Clearly, SDN demand is much greater than almost anyone predicts. Are people talking to the wrong sources about the future of networking ?
Big Switch Networks (BSN) launches Version 4.0 of Big Cloud Fabric for hardware-centric SDN data centre fabric. The Data Centre Fabric solution clearly shows the maturity gained from 5 years of shipping products while adding innovation in switch hardware through Switch Light operating system. At the same time, they have completed the transition from platform to product. A product that really has what you need in a hardware-centric SDN platform and addresses nearly all of the issues the competitors have not addressed. And it is shipping now.
There are many algorithms that can be used to for flow-based hashing to provide the best load balancing method over multiple IP or Ethernet connections but I recently learned that Cuckoo Hashing the preferred method.
I’ve been working on Mellanox S-Series switches lately in a largish network with several hundred 10GbE server ports. On the whole, the product has performed beyond my cynically low expectations and the product has good capabilities overall but the command line interface (CLI) is a really poor user experience. How about this gem for configuring […]

The Network Break is a new Packet Pushers podcast where we discuss "state of the business" in networking and enterprise infrastructure. Andrew Conry-Murray and I discuss vendors moves and news, product and ploys, analysis on product and positioning, and look at the business of networking in a short … [Read More...]

When planning network architecture for the next few years, I believe that it is important to comprehend that the network is just a one part of an overall system. The ITIL foolishness that drive most IT infrastructure processes prevents clear systemic thinking and I'm often having to explain how the … [Read More...]
The future of private infrastructure ownership is moving to a new model combines the old with the new that I describe as “dolls and babies” where the major transformation in infrastructure ownership is the transition from having babies to owning dolls. Infrastructure as Babies Enterprises buy … [Read More...]
In discussions with a stealthy networking startup today, we were discussing how their overlay network technology for an SDN-enabled WAN was able to to detect network blackouts and brownouts in the physical network. Their answer was to run Bi-directional Forwarding Detection (BFD) in the overlay … [Read More...]
Can the Internet be the “Cloud Network” ? If so, when could the transition happen (if it hasn’t started already) ? Supposition/Hypothesis As a technology, the Internet has strikingly similar properties to sharing Compute and Storage as ‘Cloud’. A large pool of resource that can be used or shared … [Read More...]
Back in 2009, while working on a network diagram in Visio, a fellow worker asked me to show him how I did certain things. I thought this a bit strange at the time, but when other co-workers started asking the same questions I was surprised. Some of them got quite excited and said nice things and it … [Read More...]
Lede: I doubt that anyone bought a Vblock because it was a market leading networking strategy. I've been a supporter of VCE in the past but I'm doubtful that choosing Cisco ACI is good strategy for customers. My view is that most customers buy VCE Vblocks as a VMware platform. What VCE offers is a … [Read More...]
TL:DR A recent project bought a low-cost network for the data centre. It cost less one-third of the market leader & half the cost of a well-known merchant silicon vendors. As a result, it is planned to last for two, maybe three years before it will be replaced. From this project I learned that … [Read More...]
