Reading Time: 2 minutesOne propertiers of VMware (standard) virtual switches was the number of ports per switch. A parameter (120 was the default in ESXi 5.x) that define how many virtual NIC and/or vmkernel interfaces you can connect to the virtual switch portgroups. This parameter was static and any changes require a host reboot. But starting with vSphere 5.5 (see KB 2064511) this parameter has become “elastic”.

Reading Time: 2 minutesSeveral 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)

Reading Time: 5 minutesStarting with VMware Horizon 7 it’s possible to 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:

Reading Time: 3 minutesScale Computing is an alternative hyperconverged solution that cover the entire stack: from the hardware, to the hypervisor and storage, to the management part. Their HC3 platform is an hyperconverged solution that can be used for small- and medium-sized businesses but also in some enterprise departments with a simple (and different) approach to virtualization and storage. Their appliances was sized to a have good compromize between computing and storage resource, but also to permit a good scalability in the datacenter. For this reason thei were all 1U size, but for this reason limited in the maximum […]

Reading Time: 2 minutesVeeam 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).

Reading Time: 12 minutesThis 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 […]
