UI/API check

1-check cluster level settings for

cpu.overprovisioning.factor

mem.overprovisioning.factor

 

2- update overprovisioning  ratio using following API 

for cpu name=cpu.overprovisioning.factor

for memory name=mem=cpu.overprovisioning.factor

http://10.220.*.*:8096/client/api?command=updateConfiguration&clusterid=01d9a06d-f493-4764-88b0-5a093dfcb491&response=json&name=cpu.overprovisioning.factor&value=2

3-List cluster

1-cluster level setting should have both settings

2-using api mentioned 2 you shoul be able to change overprovisioning  factors

3-List cluster response should show overprovisioning  factors

3Capacity calculation

used capacity

===========

(service offering of vm / overcommit it got deployed with) * new overcommit

(service offering of vm/overcommit value in user_vm_details table for that vm )*overCommit value in cluster details table for vm  cluster

Total capacity

===========

(cpu/mem).overprovisioning.factor*total actual capacity

 

 

1-calculate total capacity for cluster,pod,zone it should follow the  same formula

upgrade path

Pre upgrade steps
1-Deploy  some vms
2-Have some snapshot and template

3-set cpu overcommit  to x

4- set vmware.reserve.(mem/cpu) to true

Post upgrade steps
1-add cluster with overcommit factor x
2-Deploy a vm  where required resource for vm <= resource available in cluster according to overcommit factor
3-Deploy a vm where required resource for vm > resource available in cluster according to overcommit factor
4-stop vms and change overcommit ratio .
5-Start vms .

1- Upgrade should be successful

2-check cluster and global level settings it should list

(cpu/mem).overcommit.factor and vmware.reserve.(cpu/mem) with same values as before upgrade
3-Check cluster detail table it should have some attribute to store overcommit factor for cluster.
4-in postupgrade step-2 vm should get deployed successfully .
5- In postupgrade step-3 vm deployment should fail. 
6-in step 5 ,vm should  get max min resource based on new overcommit ratio.

Dash board display for multi cluster environment

1- Add xen , vmware, kvm clusters

2- set (cpu/meme) overpovisioning to x for xen cluster and check zone total capacity

3- set (cpu/mem)overpovisioning to x for kvm cluster and check zone total capacity

4- set (cpu/mem)overpovisioning to x for vmware cluster and check zone total capacity
