VCAP – Design: VMware vSphere Distributed Switch best practice notes

Networking, NIOC, VCAP6 - Design, vDS
In this post I will share my notes about VMware vSphere Distributed Switch best practice document in preparation for the VCAP Design exam. (Document link; https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vsphere-distributed-switch-best-practices-white-paper.pdf) Notes: The document is not updated to vSphere v6; some of the information related to v5.X only. The document includes a lot of useful information.  This post is only study notes; if you are not familiar with the technologies discussed in the document please read the document first. I have chosen to cover the rack server configuration only, but the document also cover blade server configuration Design Consideration: Goals: No single point of failure Isolate traffic type Use of traffic management and optimization Component configuration: Rack server with 8 1GbE NIC’s Rack server with 2 10GbE NIC’s Physical Switch – capable of switch clustering…

VCP6-DCV blueprint section 2:Configure and Administer Advanced vSphere 6.x Networking– Objective 2.2

blueprint, Networking, study guide, VCP6-DCV
In this post we will cover the objective from the blue print regrading NIOC, i will also use my Lab to demonstrate The following are the blueprint objective: Knowledge Define NIOC Explain NIOC capabilities Configure NIOC shares/limits based on VM requirements Explain the behavior of a given NIOC setting Determine Network I/O Control requirements Differentiate Network I/O Control capabilities Enable/Disable Network I/O Control Monitor Network I/O Control Define NIOC and  Explain NIOC capabilities: With Network I/O Control version 3 you will be able to reserve bandwidth for system traffic based on the capacity of the physical adapters on a host.Network I/O Control version 3 provisions bandwidth to the network adapters of virtual machines by using constructs of shares, reservation and limit. We can use Network I/O Control on vDS to configure bandwidth allocation for…

Updating my lab to use vDS only

Home-Lab, Networking, VCP6-DCV
At this point of my learning i will like to remove all vSS and use only vDS. i will like to migrate first my storage network and than i will migrate my management network . The plan:(Per vDS) Create a new  Switch with new DPortGroup Add hosts to the Switch i also make sure to check the configure identical network setting box Manage the physical adapters Manage the VMkerenl adapters: make sure you have dvport available. Make sure you have available uplink on you new vDS. Move the associate management vmnic to the management dvport on your vDS. re-assign the VMkernel adapters and their IP's  to the new dvport group and apply to all hosts.   Here are the screenshots: Creating new vDS Adding all of my three hosts Selecting to manage…

VCP6-DCV blueprint section 2:Configure and Administer Advanced vSphere 6.x Networking– Objective 2.1 – Part 3

blueprint, Networking, study guide, VCP6-DCV
In this post we will continue implement vDS in for our lab configuration and cover the blueprint objective. Describe vDS Security Polices/Settings: vDS security policies can be applied to the switch in several locations: Apply policy per DPortGroup Apply policy per individual port When you apply policy on a port group you will have the ability to give overwrite access to the ports too. for example if you like allow a specific port to use NetFlow you will need to allow NetFlow option on the DportGroup.   The following are the security polices that you can apply on the DPortGroup and on Individual port Promiscuous Mode Operation – Promiscuous mode eliminates any reception filtering that the virtual machine adapter performs so that the guest operating system receives all traffic observed on the wire. (Mostly…
