vSphere 5.5 - End of General Support mean?

On September 19th, vSphere 5.5 exited its general support phase and moved into something called “Technical Guidance”. In response to this, many have already moved to a newer release of the vSphere 6.x line. Whether it be for compatibility concerns or a reasonable wariness of touching what’s not broken, there are several of us who are riding the wave to the very end. Let’s talk about what “End of General Support” really means for those still running vSphere 5.5. Technical Guidance First, let’s clear up a common misconception about Technical Guidance. Specifically, it does not mean that the product becomes instantly unsupported. I hear this word thrown around a lot for products out of the general support phase, but it’s misleading to do so. VMware Support will still help in the event of an issue in an environment running these products. There are, however, some serious limitations to how far this goes now that it is outside of General Support. Many times, these cases will end ...

VMware NSX-V vs NSX-T

The software-defined data center is made possible by virtualizing the key components and functionalities of the datacenter. VMware’s NSX-V platform has made tremendous waves in the software-defined data center and has allowed organizations to be truly freed from the underlying hardware network components for data center communication. VMware’s NSX product has certainly matured over the last several releases with the latest release by the VMware being, NSX-T 2.2 VMware NSX-V vs NSX-T Comparison NSX-V (NSX for “vSphere”) is designed for vSphere deployments only and is architected so that a single NSX-V manager platform is tied to a single VMware vCenter Server instance. The NSX-V platform is the original NSX platform that has been around for a few years now. It is specifically designed with VMware virtual machines in mind as that is the legacy virtualization mechanism for workloads that has been around since the onset of server virtualization. With NSX-V, org...

ARCHITECTURE – VXRAIL VS. VSA

Hyperconverged storage solutions require the installation of a virtual storage appliance on each host. However, in the case of VSAN, because it is embedded in the ESXi kernel, all the Virtual SAN intelligence are already built in to the hypervisor and there are no additional components to install. Because it is embedded in the hypervisor VSAN provides the shortest path for I/O, making storage operations optimally efficient and does not consume CPU resources unnecessarily. Even during maintenance operations and VM migrations, storage operations are seamlessly handled. VxRail VSAN provides the software defined storage layer. There are several benefits to VSAN but the primary 2 main reasons VSAN is ideal for a hyper-converged infrastructure appliance are as follows: 1.Kernel Integration – The software controlling the storage is integrated into the hypervisor. Why is this so important? The alternative to kernel integration is using a Virtual Storage Appliance (VSA) where the stor...

EMC VxRAIL

The hyper-converged VxRail Appliance features a clustered node architecture that consolidates compute, storage, and management into a single, resilient, network-ready HCI unit. The software-defined architectural structure converges server and storage resources, allowing a scale-out, building-block approach, and each appliance carries management as an integral component. From a hardware perspective, the VxRail node is a server with integrated direct-attached storage. No external network components are included with the appliance; VxRail leaves that up to the customer (although VCE can bundle switch hardware and NSX can function as an integrated option for SDN). This allows the VxRack to seamlessly integrate into the existing network infrastructure, preserving existing investment in network infrastructure, processes, and training. Organizations benefit from the simplicity of the appliance architecture that expedites application deployment while providing the same data services expected ...

NSX Visio Diagramming Tool

The  NSX Visio Diagramming tool  provides everyone the chance to diagram their network programmatically. This removes the human time and error elements from documentation. Run the tool and within a minute (if not seconds) you have the data you need to visualise your environments current state. The Tool The tool is broken into two parts – a bundle capture script and a digram script. The Bundle script allows thePowerNSX diagramming tool will automatically go off and gather the logical topology and components from NSX and vCenter to determine what a logical topology looks like. This includes but is not limited to NSX Edges, Attached Logical Switches, Distributed Logical Routers, Distributed Port Groups, Virtual Switches and the Virtual Machines that are attached to these networks. It also supports the documentation of multi-vNIC Virtual Machines. It will collect all these, store the contents in respect The Diagram script will take a defined bundle and the data conta...
