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.
Big Switch Networks is a company in the Software Defined Network (SDN) area with a clear declared mission: to bring hyperscale networking to a broader audience, by delivering fit-for-purpose products based on hyperscale networking technologies. They have two main products: Big Tap Monitoring Fabric and Big Cloud Fabric. The first one is an entry level solution for monitoring existing networks, the second one is an advanced bare-metal SDN switching fabric intended for new data center pods such as private cloud, big data and virtual desktop infrastructure (VDI). First version of Big Cloud Fabric (BCF) was […]
As written in a previous post, VMware NSX was one of the cool topics during the past VMworld and new version of this products has been announce. User cases are more and more and probably one of most interesting (and natural) usage of Network Virtualization is the micro-segmentation. This can give an immediate advantage in using this technology, and can also give an answer to a common security issue. Today’s security models are focuses on perimeter defense, but continued security breaches show this model is not enough. A deep and more granular approach is needed […]
Of course, in this VMworld 2014 there is space also for NSX with lot of sessions, user cases and related news. Related news maybe are not so big as in the past year (the first official announce of NSX), but anyway there is something interesting. First to all the certification path on Network Virtualization: as written in a previous post, there are already the first (big) group of VCDX-NV. Now the certification page is update also with the blueprint for VCDX-NV and VCP-NV (you can already ask for the authorization for it) and the new […]
Enterprise Networking Planet has compiled its list of the Top 10 networking experts who are active bloggers and Twitter users (Enterprise Networking Planet’s Top 10 Networking Experts You Need to Follow). These individuals have varied backgrounds and professional experiences from networking engineer to industry analyst. While a number of them have been or are employed by networking vendors, their blog posts and tweets are their own words and are not endorsed by any of those companies. Here is my entry: 9. Andrea Mauro (@Andrea_Mauro) has been working with Assyrus Srl, an Italian IT company that […]
In the fabric section of System Center VMM 2012 is also possible add external hardware network load balancers and manage, in a similar way as a storage array can be added and managed. But in this case there isn’t a standard interface to remote manage the devices and each vendor must make available a supported “provider” that is just the management software part for the integration with VMM. Actually the supported devices are:
