-----------------------------------------
Kelven,
Thank you for the response,
I will help with updating the WIKI for Functional Specs.
Would you be Ok with me adding following:
It would be nice if we can set a hard/soft limit via global configs for below,
however, if we need to hardcode the logic for this release, it would work as
well. It would be nice if could do 2 concurrent operations of vmotion per host
at at time.
* When host is placed into maintenance mode, allow concurrent operations to
evacuate all VMs
It would be nice if we can set a hard/soft limit via global configs for below,
however, if we need to hardcode the logic for this release, it would work as
well. It would be nice if could do 2 concurrent operations of vmotion per host
at at time. As of now, its 1 operation regardless of number of hosts, executed
in sequence.
* Allow concurrent operations of VM deployments
Ideal to allow upto 4 operations, but we can keep as low as 2.
* When primary storage is placed into maintenance mode, use SVMotion to migrate
VMs to other DataStores. Current behaviour is VMs are shut-down, then exported
as OVF, then moved to other datastores, it would be nice to make use of native
VMWare functionality to do that and avoid many operations we do now.
Currently allowed concurrent operations are set to 8 per host, if we can allow
between 2-4 it would be great.
VSphere 5.0 maximums guide:

Please let me know what is achievable.
Thanks
