Runecast is a powerful tool to monitoring and check a vSphere environment and recently also for a VSAN environment. But it’s not over, actually there is a beta for the new version (Runecast version: 1.7.6 probably) that can analyze also NSX-V environments and this could be quite cool, considering the potentially complexity of a NSX infrastructure. I’ve tested the beta on a small lab, just to see how does it work.

Big Switch Networks announced that Big Cloud Fabric (BCF) now supports a robust ecosystem of the leading hyperconverged (HCI) solutions, including: VMware vSAN, Dell EMC ScaleIO, and Nutanix. Big Switch Networks is a company in the Software Defined Network (SDN) area with a clear declared mission: to bring network innovation to a broader audience, by delivering fit-for-purpose products based on hyperscale networking technologies.

VMware has released a new version of NSX-v, the NSX edition for vSphere environment. Note that NSX 6.4 is a new minor release, but has so many important enhancements, new features, and improvements that can be considered a new major release. The most interesting news are the support to the HTML5 vSphere Client (another little step to a complete adoption) and some new interesting features and capabilità in the distributed firewall. For more technical details on the new features, see this post.

Neil Anderson, from flackbox.com, has announced an interesting giveway to help you in the Cisco CCNA certification. The giveaway will end on January 13, 2018 11:00 pm ALMT.

After the release of VMware NSX-T v2.0 only three months ago, now VMware has released the new version: NSX-T v2.1, that will enable advanced networking and security across these emerging app architectures, just as it does for traditional 3-tier apps. More specifically, NSX-T 2.1 will serve as the networking and security platform for the recently announced VMware Pivotal Container Service (PKS), a Kubernetes solution jointly developed by VMware and Pivotal in collaboration with Google. NSX-T 2.1 will also introduce integration with the latest 2.0 release of Pivotal Cloud Foundry (PCF), serving as the networking and security engine behind PCF. In these environments, NSX-T will provide Layer […]

This is an article realized for StarWind blog and focused on the design and implementation of a ROBO infrastructure. See also the original post. Introduction The fabric of SAN (means Storage Area Network) with Fibre Channel solutions have always been a dedicated network, with dedicated components (like FC switches). But, starting with iSCSI and FCoE protocols, the storage fabric could now be shared with the traditional network infrastructure, because at least level 1 and 2 have a common Ethernet layer (for iSCSI also layer 3 and 4 are the same of TCP/IP networks).

Neil Anderson, from Flackbox, has build an amazing free Cisco CCNA Lab Guide recently which can be used to pass the CCNA exam or as a configuration reference for Cisco routers and switches. There’s a few free guides online but they all cover old out of date exam topics and aren’t great quality, but this is guide really complete (350+ pages), up to date, with good quality and simple, which people can use completely for free.

VMware has just released the new major version of NSX-T 2.0 to provides an agile software-defined infrastructure to build cloud-native application environments. When Nicira product has been released was for Linux and physical platform, but after the VMware’s acquisition has been re-engineered to be integrated in the vSphere platform, with the new name of VMware NSX (now NSX-v). NSX-T is again a version for (physical) Linux system designed for management, operations, and consumption newtork resources insied a (development) organizations. NSX-T allows IT and development teams to choose the technologies best suited for their applications.

As promised in the last VMworld, now VMware has introduced two new less-expensive versions of its NSX product targeted for the mid-enterprise. Also on NSX there are now different editions with different prices and, of course, features. The full version will be the Enterprise one (sigh… on vSphere Enterprise has gone, wasn’t better call it Enterprise Plus), the intermediate Advanced and the starter just Standard. No Essential or Essential Plus, but will be difficult and non sense (yet) apply this kind of technology to the small business.

VMware best practices for virtual networking, starting with vSphere 5, usually recommend the vmxnet3 virtual NIC adapter for all VMs with a “recent” operating systems: starting from NT 6.0 (Vista and Windows Server 2008) for Windows and for Linux that include this driver in the kernel, and for virtual machines version 7 and later. For those operating systems the choice is normally between the e1000 or the vmxnet3 adapter: the new virtual machine wizard suggest the e1000 for the recent Windows systems, but only because this driver is included in the OSes. Historically there were some […]

I’ve already talk about Big Switch in some previous posts (see Big Switch Networks has a big announce), now there are other news both in the Big Cloud Fabric (with new version 2.6) and Big Tap Monitoring Fabric (with the new versione 4.5). The Big Tap product does not need too much explanation: it’s a 1G/10G/40G network visibility fabric that leverages high-performance bare metal Ethernet switches or Dell Open Networking switches to provide pervasive and scalable monitoring of an organization’s network traffic. The new version will add some new features and will support new switches […]

One issue about VMware NSX it that it does not exist an evaluation or a trial code in order to study and test it. This because the code is still on a Nicira web site and is much more restricted compared to other VMware code. Also VMware partner may be not entitled to download it, unless they don’t have the NSX competency. Individual can got an access only through one of the NSX official course: I’ve take the ICM on NSX 6.0 and the access on Nicira web site was granted me at the end […]

During the first Italian Tech Field Day Extra (at Cisco Live 2015 in Milan) the company that we met was, of course, Cisco. For an entire day we had different sessions with different Cisco’s people and talk about their different products, but also their different solutions and approaches. It was a full day (January 26th) from 9:00 to 17:00 with a bunch of interesting information (especially for me, where the networking part is usually the simplest part of my project, considering the medium size of Italian projects and environments).

After the big announce in the previous week, now Big Switch Networks will launch its BSN Labs to the public. What is BSN Labs? It’s an online portal to test drive its SDN products, including Big Cloud Fabric and Big Tap Monitoring Fabric… like a hands-on-lab it could be very useful also for understand how the products works and its features. While traditional networking products require access to physical hardware in order to use or test products, Big Switch Labs enables instant online testing of its products via this one-of-a-kind demo environment.
