All the parts that related to the course:Virtualization & Cloud Computing
Part I: Answer the question(in short)why would you use vMotion or svMotion?


Example:vMotionallows a virtual computer to move between physical host servers. I would use vMotionbecause while the virtual computer is running you can move a server to a different hardware, while not interruptingthe end-user. svMotionallows you to move disk files along with a virtual machinebetween datastores, also while the machine is running. This allows for maintenanceand or upgrades to the virtual machines and disks, even from different places. I would use svMotionalso because you can balance the storage on a virtual machine or disk which makes the virtual machine more effective and faster.


Part II:Summarize in one sentence what have you learned from this session(see the attachment).


Example:This session informed me that vSphereFault Tolerance only supports VMsconfigured up to 8 vCPUs and 128GB of RAM. Any moreand Fault tolerance wouldn't work with the VM.


Part III:What is a troubleshooting process?


Example:The troubleshooting processin Vmwareis the implementation of vSphere, you need to identify the symptoms of the problem.And determine which components are affected, and test possible solutions.

Methods for making vCenter Server available: • Use vSphere HA and vCenter Server High Availability to protect the vCenter Server virtual machine. VMware vSphere: Install, Configure, Manage | 9-10© 2018 VMware, Inc. About vSphere HA vSphere HA uses multiple ESXi hosts that are configured as a cluster to provide rapid recovery from outages and cost-effective high availability for applications running in virtual machines.

Virtual Machine C Application Virtual Machine F Application Virtual Machine D Application Virtual Machine A Application Virtual Machine B Application = vSphere HA Cluster VMware vSphere: Install, Configure, Manage | 9-14© 2018 VMware, Inc. vSphere HA Scenario: Datastore Accessibility Failures If VM Component Protection (VMCP) is enabled, vSphere HA can detect datastore accessibility failures and provide automated recovery for affected virtual machines. You can determine the response that vSphere HA makes to such a failure, ranging from the creation of event alarms to VM restarts on other hosts: • Permanent device loss (PDL): – Unrecoverable loss of accessibility. – Occurs when a storage device reports the datastore is no longer accessible by the host. – Response can be either Issue events or Power off and restart VMs. • All paths down (APD): – Recoverable. – Represents a transient or unknown accessibility loss. – Response can be either Issue events, Power off and restart VMs--conservative restart policy, or Power off and restart VMs--aggressive restart policy. VMware vSphere: Install, Configure, Manage | 9-15© 2018 VMware, Inc. vSphere HA Scenario: Protecting VMs Against Network Isolation vSphere HA restarts VMs if their host becomes isolated on the management or vSAN network. Host network isolation occurs when a host is still running, but it can no longer observe traffic from vSphere HA agents on the management network: • vSphere HA tries to ping the cluster isolation addresses. A network isolation address is an IP address that is pinged to determine whether a host is isolated from the network. • If pinging fails, the host declares that it is isolated from the network. This protection is provided even if the network has become partitioned.

Importance of Redundant Heartbeat Networks In a vSphere HA cluster, heartbeats have the following characteristics: • They are sent between the master host and the slave hosts. • They are used to determine whether a master host or a slave host has failed. • They are sent over a heartbeat network. Redundant heartbeat networks ensure reliable failure detection and minimize the chance of host- isolation scenarios. Heartbeat network implementation: • Implemented by using a VMkernel port that is marked for management. • Implemented by using a VMkernel port that is marked for vSAN traffic when vSAN is in use. VMware vSphere: Install, Configure, Manage | 9-17© 2018 VMware, Inc. Redundancy Using NIC Teaming You can use NIC teaming to create a redundant heartbeat network on ESXi hosts. NIC Teaming on an ESXi Host VMware vSphere: Install, Configure, Manage | 9-18© 2018 VMware, Inc. Redundancy Using Additional Networks You can create redundancy by configuring more heartbeat networks. On each ESXi host, create a second VMkernel port on a separate virtual switch with its own physical adapter. Redundant management networking enables the reliable detection of failures and prevents isolation or partition conditions from occurring, because heartbeats can be sent over multiple networks.
