We are currently running ONTAP 8.0.2P2 7-mode with a V-series 6210. It appears the largest Array LUN we can provide to the v-series is approx. 3TB. Which by the time you create an aggregate and volume you are down to basically 2TB of usable space to assign to a vFiler. Are there any options if you have a vFiler that needs more than 2TB?
The Maximum array LUN size supported with the latest version of ONTAP is approx 3TB and it’s documented in V-Series support matrix available on now.netapp.com.
However, Based on your question, it sounds like you are describing mapping one array LUN to an Aggregate for one specific host or application. While this would work, I would recommend you take different approach. When creating your NetApp aggregate, you should use multiple array LUNs to create a larger aggregate. This way your storage pool (aggregate) can me very large containing multiple array LUNs and used for multiple hosts.
