Creating and Administering Resource Pools

Question 1

Resource Pool Hierarchies.

Answer 1

The root of the Resource Pool hierarchy can be a standalone host or a DRS cluster. Figure 16-1.

1. Flexible hierarchical organization.
2. Isolation of resources between pools and sharing of resources within pools.
3. Access control and delegation.
4. Separation of resources from hardware.
5. Management of sets of VMs running a multitier service. These VMs need each other and therefore need the same priorities to resources.

Question 2

Defining the Expandable Reservation Paramter.

Answer 2

Allows a pool to borrow resources from a pool that is higher in the hierarchy.

Question 3

vFlash Architecture.

Answer 3

Pg. 622

Question 4

Creating/Removing a Resource Pool.

Answer 4

Activity 16-1.

Question 5

Configuring Resource Pool Attributes.

Answer 5

1. Shares: Establish relative priority between sibling Resource Pools.
   Relative: Settings, Low, Normal, High and Custom.
   Proportional: Amount of a resource received depends on how many other siblings are competing for the same resource.
2. Reservation: Guarantee that a fixed amount of a certain resource is to be given to this Resource Pool. VMs do not have to compete using their shares for these resources.
3. Limit: Cap on the aggregate physical resources that can be consumed by the VMs in the Resource Pool.
4. Expandable Reservation: Allows Resource Pool to borrow from parent.

Question 6

Adding/Removing VMs from a Resource Pool.

Answer 6

Can drag/drop VMs to Resource Pool.

Question 7

Create/Delete vFlash RP.

Answer 7

Flash resource created when VM is powered on, destroyed when it is powered down.
Flash read cache will support write-through or read caching as configured.

Question 8

Determining Resource Pool Requirements.

Answer 8

Purpose of RPs is to establish relative priorities within the same host or cluster of your vSphere.
