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 There’s a few free guides online but they all cover old out of date exam topics and aren’t great quality, but this is guide really complete (350+ pages), up to date, with good quality and simple, which people can use completely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.

RVtools is a great tools to inventory a virtual infrastructure based on VMware vSphere, with or without vCenter Server (works great also on standalone ESXi hosts). RVTools supports ESX Server 3.5, VirtualCenter 2.5, ESX Server 3i, ESX Server 4i, VirtualCenter 4.x, ESX 4.x, VirtualCenter 5.0, VirtualCenter Appliance, ESX 5.0, VirtualCenter 5.5, ESX 5.5, VirtualCenter 6.0, ESX 6.0, VirtualCenter 6.5 and ESX 6.5, so all you can have (also legacy versions) in a datacenter. And it’s totally free.

Several people are disabling IPv6 support in ESXi for different reasons: because of the minimum privilege principle (if you are not using a service, why you have to keep it enabled?) or simple because they don’t want any IPv6 address in the network. On Linux and Windows systems is become very difficult disable it and Microsoft itself does not recommend disabling IPV6: ” We do not recommend that you disable IPv6 or its components, or some Windows components may not function.” (https://support.microsoft.com/en-us/kb/929852)

Starting with VMware Horizon 7 it’s possible choose two different way to deliver space optimized desktop pools: using VMware Composer and linked clones technology (existing from several years) or use the new instant clones technology (introduced with vSphere 6.0). Similar to View Composer linked clones, instant clones share a virtual disk of a parent VM and therefore consume less storage than full VMs. In addition, instant clones share the memory of a parent VM. Instant clones are created using the vmFork technology. An instant-clone desktop pool has the following key characteristics:

WekaIO is a new startup (just emerged from stealth mode) with the goal to improves IT agility by delivering software-centric data storage solutions that unlock the true promise of the cloud. WekaIO has its headquarters located in San Jose, California, but the most of its engineers are in Tel Aviv, Israel. WekaIO Matrix software is ideally suited for performance intensive workloads such as Web 2.0 application serving, financial modeling, life sciences research, media rendering, Big Data analytics, log management and government or university research.

Veeam Software has announced, during the last Nutanix .NEXT event, an expanded partnership with Nutanix  in which Veeam becomes the Premier Availability solution provider for Nutanix virtualized environments. What does it mean? First that Nutanix adds Veeam as a Strategic Technology Partner within the Nutanix Elevate Alliance Partner Program. But more important that Veeam will deliver support for Nutanix’s Hypervisor, AHV (maybe later this year, more realist in the next year).

This is the last part of a set of posts realized for StarWind blog and focused on the design and implementation of a ROBO infrastructure. See also the original post. Design a ROBO infrastructure. Part 5: Data protection solutions Business continuity aspects In previous posts we have already discuss about several business continuity aspects in ROBO scenarios. For example, a reasonable availability level could be between 99% and 99,99%, but there are some workloads that may require higher level (or other that are not critical at all). But availability could be achieved by a good infrastructure design and […]

This is the fourth part of a set of posts realized for StarWind blog and focused on the design and implementation of a ROBO infrastructure. See also the original post. Design a ROBO infrastructure. Part 4: HCI solutions 2-nodes hyperconverged solution As written in the previous post, for ROBO scenario the most interesting HCI (Hyper-Converged Infrastructure) configuration is a two nodes configuration, considering that two nodes could be enough to run dozen VMs (or also more). For this reason, not all hyperconverged solutions could be suitable for this case (for example Nutanix or Simplivity need at least 3 […]

The new VMware Virtual SAN (or vSAN) 6.6 adds several enchaments and new features as described in the announce notes. Most of those aspects are related to data and cluster resiliency (as expected by a storage solution), including:

Past week Cohesity has announced the new release of its product and platform: Cohesity DataPlatform 4.0 and Cohesity DataProtect 4.0 expand Cohesity’s capabilities far beyond backup to bring together even more data formats and infrastructures, including object storage and network-attached storage (NAS), onto its hyperconverged platform. In less than two years Cohesity has announced the v1, the v2, the v3 and now the v4 of Cohesity Data Platform, a product designed to consolidate all secondary storage use cases on a unified environment that helps organizations control growing data demands.
