During our previous posts we have installed and configured a vCenter Server and ESXi hosts. Now that we have our cluster configured with HA and DRS features, lets add our ESXi hosts to the cluster. First, right click on the cluster and select Add host. Then, provide the FQDN or the IP address of the host you need to add to the cluster. Click next to continue. Provide the username and password to connect to the host and click next to continue. You will get a prompt about validation of host certification. Accept it to continue. Wizard will provide a summary of information about the host. Click next to continue.…

Configure HA/DRS Cluster
Now we have a vCenter Server configured and running with an external PSC but we are yet to add hosts to the vCenter and enable vSphere features like vSphere HA and DRS. What is vSphere High Availability vSphere HA is a feature enabled at the vSphere cluster level to reduce unplanned downtimes. vSphere HA can protect applications availability in following ways, It can protect virtual machines against a server failure by restarting affected VMs on a another available host. It can protect against an application failure by continuously monitoring a virtual machine and resetting it once a failure was detected. vSphere HA can protect against a datastore accessibility failure by…

Install & Configure: VMware vCenter Server 6.5 with External PSC
Now we have multiple ESXi hosts installed and configured in our environment. Managing those ESXi hosts individually through host web client or vSphere legacy client can be a tedious task. Also you are missing features like vSphere HA, DRS, VM cloning and template management. Solution to all those problems is installing an vCenter server to centralize management of ESXi hosts. Now let’s install and configure VMware vCenter server v6.5. You can download a trial version of vCenter Server from my.vmware.com. Since the vSphere version 5.0 VMware offered an appliance version for vCenter but windows version had more capabilities and features. But from version 6.0 and 6.5 VMware has put more…

Introduction to VMware vSphere
VMware has introduced a broad range of products to use in virtualized environment to create a true software defined data center. Their products falls in many categories including datacenter and cloud infrastructure, infrastructure & operations management, network and security and application management etc. Out of those VMware vSphere is the core product portfolio from VMware. Over the years vSphere has grown exponentially with products like Operations manager, Replication, data protection and NSX. Today we will discuss about two products from vSphere which common to all their licensing categories. VMware ESXi Hypervisor ESXi (or previously known as ESX) is the founding stone to their almost all the products. It’s a type…

Welcome to Virtualization
Virtualization, in the simplest form is running workloads in a virtual environment. It simulate or emulate physical resources in a virtual environment in order to achieve better utilization, faster deployment times and easier management. We need a special software component called the Hypervisor in order to provide physical resources to virtualized workloads. There are two types of Hypervisors, Type one hypervisor Type two hypervisor Type one hypervisor This type of hypervisors run directly on host hardware. So they are also called bare metal hypervisors or native hypervisors. Examples for these are, VMware ESX and ESXi Microsoft Hyper-V Red Hat Enterprise Virtualization (RHEV) Citrix XenServer Oracle VM These hypervisors do not…
