Chronological archive of briefs published in 2015.
In the last few years, with an exponential growth of interest in the SDDC (Software Defined Data Center), many vendors have shown an interest, and some have even managed to engineer a more-or-less decent SDN...
Cisco Nexus 9k Switches make the ACI Fabric, which is the Control and the Data plane of ACI Architecture.
At this point I will assume that you already read my previous posts about: Cisco ACI Fundamentals.
Before we get deeper into the ACI (Application Centric Infrastructure) as the Cisco's official SDN solution, we need to clarify a few terms that will be used:
This is a question I´ve been hearing a lot when we present the OpenStack to a new client, mostly from the guys who control the Networking infrastructure.
The basics of the OVS (Open Virtual Switch) and OpenStack Neutron module were described in my previous post.
Practical notes on openstack neutron and ovs (open virtual switch) translated to the network engineers language — OpenStack, VMware configuration, design, and troubleshooting guidance.
In my next post I'll be focusing on the NSX and Palo Alto integration, and all the improvements this brings to the Micro Segmentation.
To prepare for the VCIX-NV Exam, the ideal environment to practice is similar to the one we may find on the Hands-on-Labs:
TIP: Be sure to use the HUU (Host Upgrade Utility) when adding the Blade to the UCS architecture, to make sure you have the latest drivers and the Firmware.
TIP: In FCoE world there are no HBAs, but there are CNAs instead. All the Storage concepts stay the same.
OpenStack is basically an open source CLOUD stack, and it delivers the possibility to consume the platform resources using the REST API calls.
Unified Fabricis a term for all of the equipment that makes LAN and SAN possible. There are two different networks (LAN as Front-end and SAN as Back-end) that we are trying to “converge”, and 10G is an enabler of...
TIP: If you are a Networking professional, the odds are you don’t know much about Web services, and RESTful API everyone is mentioning all the time is your confusion point.
Before I get into the Python for NX-OS, let me explain a few concepts that I've seen Network Engineers have been struggling with.
