VMware had some pretty cool announcements surrounding OpenStack recently at VMworld. They pertained to VMware Integrated OpenStack or VIO. What is VMware Integrated OpenStack It is well-known that OpenStack is a fantastic framework that provides developers with cloud-styled APIs. Coupled with tools, this can run on top of any virtual infrastructure. It takes a strong, well versed and dynamic team to run an OpenStack cloud. From a hardware perspective OpenStack provides APIs for Compute, Network, Storage and Image management coupled with CLI tools, a Web Portal and SDKs. VMware Integrated OpenStack seeks to leverage an open and vendor-neutral ecosystem familiar to developers on top of the industry standard virtualization platform that VMware provide many customers world-wide. VMware are one of the largest contributors to OpenStack and this expertise allows an easy path for customers to design, deploy and operationalise OpenStack on VMware SUPER Nova Nova traditionally provided the compute APIs … Continue reading
The update of NSX for vSphere to 6.1 brings around a few new features which nicely complement the existing virtual networking suite. I am going to comment on some of the larger and more exciting features and some things that I’ve been waiting on for a while. ECMP Equal Cost Multi Path is now supported within the NSX software. This allows network topologies to have up to 8 paths supported in a two stage fabric. This subsequently provides 80Gbps of aggregate North-South bandwidth for a particular application or topology. To further allow scale-out of these networks, ECMP applies to static routing, OSPF, iBGP and eBGP routing protocols. From a design point of view it is now possible to provide traffic load sharing between the Distributed Logical Router and the NSX edges and subsequently from the NSX edges to the physical network peerings. L2 VPN It has been commented in many … Continue reading
There are points in all our lives that define us. They can be personal or professional. They can be large or small. I had a very large and personal point in my life occur during the week. I welcomed my firstborn son to the world. Felix Alexander Burke came into the world on Thursday the 14th of August at 1:26pm. He weighed 5 pound 15 (2.7kg) and he is doing well. Mum and a Dad are doing well and learning the joys of parenthood. It is pretty amazing how instinctive it is for someone who never saw themselves as paternal. I’ve done a lot of things for the first time this week. It’s pretty awesome. Now, I think it’s time for a nappy change!
SPARK : CCIE RS v5 certification guide ROUGH CUT I am currently working on my CCIEv5 RS. The new blueprint change has added some good new information and removed obsolete technologies from the test. The rough cut of the new CCIE Routing and Switching v5.0 Official Cert Guide v1 5e book (which at this stage has chapters missing) appeared on Safari Books recently. This was great for me as my workplace provides me a subscription. Written by the ever so smart Narbik Kocharians this book takes the certification series to the next level. I thought I would post my thoughts on it so far. Writing style Narbik has a legacy around how much he knows. He can recite all sorts of technology details and is big on what he terms ‘chalk talks’. These ‘chalk talks’ are deep dives into a technology leave no stone unturned into why the technology we … Continue reading
Cisco VIRL : Terminal Mutliplexing There is a built-in console with VIRL. It allows access to the CLI of the network devices that you deploy so you can administer them. In previous build there were some clicky click features. Due to the dynamic shared nature of VIRL when you deploy a topology there are large number of ports in a pool it chooses from. If you are constantly changing, restarting, deploying or tweaking your VIRL platform these ports can change quite a bit. Previously you had to individually open each console and type telnet : from your or right-click on each router and open a terminal in VM Maestro. If you have a large topology this can be frustrating. Let alone the fact you miss out on great features like SecureCRT’s send to all tabs. It is great for running show ip route eigrp on all ten tabs at once! … Continue reading
