Hi jt,

I am not sure if I agree with you for the following reasons.

1- Many of the virtual machines space get flatten with temp data which you might needed only once & after that you never needed that space any more.

2- In the case I have pointed to in point one in this reply, SAN Thin provisioning feature will not allow you to reclaim that space as it will see it being used.

3- Who said disk space is cheap, specially on high end storage.

4- Thin provision on some storage vendors get to be quite expensive & some of them does not even support it.

In the end, everyone has his way of doing things.

I have to disagree with this post. First and foremost, a VM that has rapid shifts up and down in disk space utilization should NOT be thin provisioned at the VMFS level to begin with. Thin at the SAN or thick – to prevent the LUN from being over committed and thus pause everything. Second, spending the money on a SAN feature license that covers all connected servers compared to the cost and constant changing “what this license includes” VMWare license makes it a no brainer – the SAN feature will be cheaper. Third – thick provisioning isn’t evil if you are dealing with less than 10tb. Disk is cheap, and you’re paying for the SANhead anyway, so don’t try to solve things with added licenses.
