What’s New in VMware NSX Data Center for vSphere 6.4.2

With this latest release, VMware NSX Data  vCenter for vSphere 6.4.2 continues to improve overall efficiency of the network, enhance security with Context-Aware Micro-Segmentation, and deliver operational enhancements to the NSX platform. Here are just a few highlights of what’s new. Multicast Routing Support With VMware NSX Data Center for vSphere 6.4.2, NSX Logical Routers now have the capability of routing IPv4 multicast traffic. The location of the Virtual Machine multicast receivers (identified by their hypervisor, Logical Switch and Virtual NIC) is discovered thanks to IGMP snooping within the NSX domain. The Edge Service Gateway (ESG) runs PIM sparse mode with physical routers and coordinates with the Distributed Logical Router (DLR) in order to provide both ways multicast connectivity from Virtual Machines to the outside world. For added multicast replication performance in the VXLAN Overlay, NSX leverages Layer 2 multicast in an underlying...

EMC VxRail hyper-converged infrastructure appliances installation

Before VxRail initialization, you need to prepare the following information for each component, System Setting Time zone, NTP server, DNS server Management Setting ESXi hostname prefix, Domain ESXi starting address for IP pool, ESXi ending address for IP pool vCenter Server hostname, vCenter Server username, vCenter Server password vCenter Server management username, vCenter Server management password Datacenter name, Custer name VxRail Manager hostname, VxRail Manager IP address Subnet mask, Gateway ESXi password, VxRail Manager password vMotion Setting Starting address for IP pool, Ending address for IP pool Subnet mask, VLAN ID Virtual SAN Setting Starting address for IP pool, Ending address for IP pool Subnet mask, VLAN ID VM Networking Setting VM Network name, VLAN ID When you finish the hardware installation and network connection, you can start the initialization. According to you prepared information, you input the required info i...

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...
