Some of the network gear vendors cast a wary look at network management vendors, particularly those who do continual, automatic discovery of the network inventory and connectivity.  Why? We know what’s actually out there, and what’s actually being used. We had one customer in the insurance industry who was due to renew their maintenance agreement with a large, well-known network gear vendor. The typical scenario was to be handed a spreadsheet by the salesperson, listing the serial numbers of the network devices they had purchased, together with a summary of maintenance charges. Prior to the meeting, the network manager ran an inventory report sing Entuity, and – not uncommonly – discovered that the list of devices under maintenance as tracked by the network hardware vendor did not match the list of devices currently running.  In fact, they were considerably off. 30,...

Will @Avaya Redefine Software Defined Networking? By @Entuity | @CloudExpo [#Cloud #SDN]

Will Avaya Redefine Software Defined Networking (SDN)? Avaya’s belated entry into the SDN arena is intriguing; they combine late entry with a new appliance – the Open Networking Adapter (ONA).  The ONA being an Open vSwitch in a box, rather than its usual deployment as part of a server virtualization installation.  The idea of providing a small form-factor, low cost, SDN capable switch is appealing in that it allows easy extension of the SDN management domain to individual appliances – allowing zero-touch provisioning of security, QoS, etc. One question that springs to mind is wh...

Culture Shock By @MJannery | @CloudExpo [#SDN #Cloud]

When the melting pot boils down to it, our network is its own culture, with recurring traffic patterns, similar end users, and equipment named after inside jokes only your company will understand.  Just like living within your own culture, it's important to not only understand HOW patterns develop, but WHY as well. When troubleshooting a network, it's important to know what tasks it performs on a daily basis. Denise Fishburne, a 30 year network engineer, highlights three areas to consider when finding a problem in the network. The article was a quick read, but the points she argu... (more)

Scaling with Distributed Pollers By @MJannery | @CloudExpo [#SDN #Cloud]

Enterprise in Disguise - Scaling with Distributed Pollers Not all network management solutions are alike, even though they may sound that way sometimes. A sure sign of a network management tool trying to pass itself off as an enterprise solution is when it implements distributed polling as a way to scale. These systems scale server capacity by adding distributed pollers, each sharing a portion of the overall CPU load. But any network monitoring architect can tell you that the bottleneck in infrastructure management is I/O to the database. Having multiple pollers simultaneously se... (more)

The Non-Tangibles Become Tangible By @Entuity | @CloudExpo [#Cloud]

We recently changed over the entire phone system in our London office.  After four years, the equipment failed, and it was time to update.  As we did so, we also changed vendors.  Why? It occurred to us that, for four years, we had put up with horrible support – we were the victims of fraud at one point, and the vendor did nothing to support us with the main telecom provider.  The phone system could go down for a day before they came out to repair it.  No big deal, right?  What high tech software company needs to communicate to the outside world? So it was time to put in a new ph... (more)
