The object of this testing is to demonstrate robust performance of the ME5024 during these phases of the VDI life cycle:
- Login phase: For this test, 500 users log in at the rate of two users each second (all users in <5 minutes). A short login period is specified to stress the environment with a heavy workload during the login phase to demonstrate performance.
- Typically, user login and logoff will be gradual during the beginning and end of a work shift. Gradual login and logoff is less demanding on the storage appliance and workload hosts.
- Administrators should design their VDI environment to accommodate mass login and logoff events.
- Steady state: Login VSI Knowledge Worker tasks run on each VM to generate I/O. Steady state is configured to run for 30 minutes for this test. Steady state is less resource intensive than the login phase.
- Logoff, and VM refresh: Login VSI logs off all 500 users and all user VM desktops refresh from the gold image. Refresh causes a period of sustained, elevated resource demand on the storage as desktops are refreshed.
Note: Horizon instant clone pool creation and deletion, although not shown in this testing, are also part of the VDI Lifecycle. Instant clone pool creation and deletion activities cause brief but heavy demand on storage resources. Avoid creating or deleting instant clone pools while other phases of a VDI workload are active (login phase, steady state, or logoff and VM refresh).
