Have you ever tried using the USB Console port on your network hardware? Me neither, and that’s mainly because the instructions typically begin with Download and install the USB console driver for your operating system,
at which point I exhale deeply and get out my USB serial adapter instead. I think Opengear must have heard me sighing because the ACM7004-5 Remote Site Gateway device they’ve sent me to look at has four USB console ports built in.
The compact ACM7004-5 packs more power than its diminutive stature might at first suggest. Taking a look at the back panel reveals a densely-packed set of ports offering a total of four switched GigabitEthernet ports, four serial console ports (RJ-45) and four USB ports:
As with the other small Opengear devices I’ve tested, this model comes with a single rackmount bracket so it can be attached within a rack with relative ease. It’s only about five inches wide, so it’s not too hard to find a free space to locate it. If you aren’t blessed with a rack, there are small rubber feet that can be stuck on the underside. The power port is interesting; I find myself shouting for Continue reading

PowerNSX is a PowerShell module that abstracts the VMware NSX for vSphere API to a set of easily used PowerShell functions. It aims to focus on exposing New, Update, Remove and Get operations for all key NSX functions as well as adding additional functionality to extend the capabilities of NSX for vSphere management beyond the native UI or API.
PowerNSX works closely with VMware PowerCLI, and PowerCLI users will feel quickly at home using PowerNSX. Together these tools provide a comprehensive command line environment to manage your VMware NSX for vSphere environments.
PowerNSX continues to be updated and feature requests are welcome via the issues tracker on the projects GitHub page. Remember that VMware does not support this module, and PowerNSX comes with no warranties express or implied. Please test and validate PowerNSXs functionality before using in a production environment.
So what does your free download of PowerNSX give you?

OpenStack is becoming the de facto standard for infrastructure orchestration for NFV deployment by leading Communications Service Providers (CSPs).
The challenge becomes scalability.
It's 2016 and almost every site using Cloudflare (more than 4 million of them) is using IPv6. Because of this, Cloudflare sees significant IPv6 traffic globally where networks have enabled IPv6 to the consumer.
The top IPv6 networks are shown here.
The chart shows the percentage of IPv6 within a specific network vs. the relative bandwidth of that network. We will talk about specific networks below.
IPv6 is faster for two reasons. The first is that many major operating systems and browsers like iOS, MacOS, Chrome and Firefox impose anywhere from a 25ms to 300ms artificial delay on connections made over IPv4. The second is that some mobile networks won’t need to perform extra v4 -> v6 and v6 -> v4 translations to connect visitors to IPv6 enabled sites if the phone is only assigned an IPv6 address. (IPv6-only phones are becoming very common. If you have a phone on T-Mobile, Telstra, SK Telecom, Orange, or EE UK, to name a few, it’s likely you’re v6-only.)
How much faster is IPv6? Our data shows that visitors connecting over IPv6 were able to connect and load pages in 27% less time than visitors connecting Continue reading
