Chapter 7: Working with VMware vSphere

Which parameters are used by ESXi hosts to shape outbound traffic?

Average Bandwidth, Peak Bandwidth, Burst Size

What are the advantages of NIC teaming?

Load-balancing and failover settings

Describe Thick Provision Lazy Zero

Space is allocated during creation and data remaining on the physical device is not erased during creation

Describe Thick Provision Eager Zero

Space is allocated during creation and data remaining on the physical device is zeroed out

In Virtual Disk Provisioning, what is overallocation and what are the advantages of using it?

The process of assigning more disk space to your virtual disks than you have space available on the VMFS data store. Using Thin Provsioning, administrators can make maximum use of available storage space by employing overallocation.

Includes the management network port used to connect to remote consoles sch as the vSphere Client, as well as ports for network storage, vMotion, migration, and fault tolerance. Each VMkernel port must be configured with it s own IP address and gateway

Describe the purpose of VMkernel Ports

Describe RDM

The Guest OS stores data directly on the computer's storage (local or SAN)

Describe the purpose of Trunk Ports

Used by the physical switch to pass packets from multiple VLANs to the host using VLAN tags.

Describe the purpose of Uplink Poo's

Used to connect one or more physical network adapters to the virtual switch. While a virtual switch does not need to be uplinked to the physical network, two virtual switches cannot share the same physical network adapter. When two or more physical network adapters are connected to the same switch they can be "teamed" using network policies to increase performance and provide fault tolerance in case one network adapter or physical switch fails.

Describe the purpose of Virtual Machine Ports

Used to handle traffic between virtual machines and between VMs and VMs and the physical network. VM ports can be divided into port groups to separate traffic and provide more control options

Describe Thin Provision

Uses only as much data store space as the disk initially needs
