Table II.18 – Test case: storage resource reservation
Storage resource reservation test description
Test purpose To verify that the CSC reserves available storage resource (e.g., storage space and LUN)
for the VM.
Reference [ITU-T Y.3513] clause 7.2.5
Test sequence Step Type Description Result
1 Stimulus The CSC configures storage reservation for VM A, which has
guaranteed minimum allocation of storage space.
2 Stimulus The CSC runs an application to perform heavy consumption
of storage usage on VMs hosting in the same host except for
VM A. The total consumption of storage is close to the
amount of the storage available for the host.
3 Stimulus The CSC performs heavy consumption of storage usage on
VM A.
4 Check VM A can get the storage resource.
Test verdict It is deemed as successfully terminated if all the checks are successful, otherwise it is
deemed as failed.
II.2.5 Test case: I/O performance
Table II.19 shows the test case for I/O performance.
Table II.19 – Test case: I/O performance
I/O performance test description
Test purpose To verify that the CSC constrains I/O traffic of a particular VM with a specified level.
Reference [ITU-T Y.3513] clause 7.2.4
Test sequence Step Type Description Result
1 Stimulus The CSC runs an application to perform heavy reading and
writing of storage on VM A. It records the actual IOPS
obtained by VM A.
2 Stimulus The CSC configures I/O performance limitation for VM A. The
IOPS limit configured is significantly lower than the IOPS
obtained in step 1.
3 Stimulus The CSC runs an application to perform heavy reading and
writing on VM A.
4 Check The actual IOPS obtained by VM A does not exceed the
limitation.
Test verdict It is deemed as successfully terminated if all the checks are successful, otherwise it is
deemed as failed.
II.2.6 Test case: storage life cycle management
Table II.20 shows the test case for storage life cycle management.
