Thick of Thin Provision LUN/Volume on the Physical Storage Array for VMware 6.x

Is it better to provision Thick or Thin LUN/Volume  on the Physical Storage Array.

If it is Thin on the  Physical Storage Array, does it matter if we configure the DataStore as Thin or Thick in VMware or
Do I stick to Thin on VMware too.

Advice will be   appreciated regarding the  implications.

This is a good article on SAN provisioning and the dangers presented when using thin provisioning on a thin provisioned SAN.

Bryant SchaperCommented:
Thin provisioning allow oversubscribing the datastore or the lun, if managed properly it can be very flexible.  We thin provision both, unless we have servers that are going to be consuming disk space up and down frequently like SQL logs and such.  They are not big luns but fixed

That is a highly informative article ITguy565 - Thank you!
I guess the recommended practice is  THIN Provision on  Physical SAN and  Thick on  VMware's  Data Stores to keep "check & balance".

Appreciate your Advise Bryant too - Thank you!

I think you should add another rule ....

If services you provide should be High Availability then Thin provisioning might be an Unacceptable RISK.
(As it adds an extra failure mode you cannot control from within the platform  to the mix).
Other non critical system may cause your critical system to fail if the storage becomes full.... on SAN... while according the the local bookkeeping the disk is only 10% full.
