Logical Diagram of VMware vSAN Stretched Cluster Physical Diagram of VMware vSAN Stretched Cluster Last week I deployed a test environment of VMware vSAN Stretched Cluster which is running on Dell EMC VxRail Appliance. In this post we will describe how to setup VMware vSAN Stretched Cluster on Dell EMC VxRail Appliance. Above figure is the high level of physical system diagram. In site A/B there are six VxRail Appliances and two 10GB Network Switch which are interconnected by two 10GB links, and each VxRail Appliance has one 10GB uplink connects to each Network Switch. In site C, there are one vSAN Witness host and one 10GB Network Switch. For the details of configuration of each hardware equipment in this environment, you can reference the followings. Site A (Preferred Site) 3 x VxRail E460 Appliance Each node includes 1 x SSD and 3 x SAS HDD, 2 x 10GB SFP+ ports 1 x 10GB Network switch Site B (Secondary Site) 3 x VxRail E460 Appliance Each node includes 1 x SSD and...

When you login into  HyperFlex Dashboard  by administrator, that dashboard is showing the current status of the cluster in UCS Manager. Click  Performance  in the side menu, it shows the performance display for the servers in the cluster. Click  Virtual Machines  in the side menu, it shows the status of each virtual machine is runing in the cluster.

The above is the physical diagram of VxRail Cluster (3 nodes). In this post I will show how to add one VxRail Appliance into this VxRail Cluster (From 3 nodes to 4 nodes). NOTE: The model of each VxRail Appliance is E460. Before the node expansion, you need to verify each Appliance is running in health in dashboard of VxRail Manager. The above is the final physical diagram of VxRail Cluster after scale out. Now we start the node expansion. You have just mounted a new VxRail Appliance (E460) and cabled it up to the top of each rack switch. When you power it on you can see a notification appear in the top left corner of VxRail dashboard. Click “ Add Node “. When you initially configured your VxRail Appliance, you specified an IP pool for ESXi, vMotion and vSAN. You can see that there available IP addresses in these pools, so the only additional action is to set an ESXi password. Click the scroll bar, then click the “ ESXi Password “. Enter the  ESXi  and ...

These interview questions are categorized into the following technical areas: Hypervisor Fault Tolerance (FT) Virtual Networking vCenter Server Virtual Storage (Datastore) What’s New in vSphere 6.0 Content Libraries vSAN vApp and Miscellaneous Hypervisor What is VMKernel and why it is important? VMkernel is a virtualization interface between a Virtual Machine and the ESXi host which stores VMs. It is responsible to allocate all available resources of ESXi host to VMs such as memory, CPU, storage etc. It’s also controlled special services such as vMotion, Fault tolerance, NFS, traffic management and iSCSI. To access these services, VMkernel port can be configured on ESXi server using a standard or distributed vSwitch. Without VMkernel, hosted VMs cannot communicate with ESXi server. What is the hypervisor and its types? A hypervisor is a virtualization layer that enables multiple operating systems to share a single hardware host.  Each operating syste...
