Maximum LUN size. Maximum VMFS volume size.

Hi everyone!

Do you have an example of a LUN bigger than 16TB connected to your vSphere? Maybe 32TB? Do you have a VMFS 5 or 6 volume bigger than 16TB?

According to the information I have found the limitation of VMFS volume is 62TB. Unfortunately I cannot find the confirmation that a storage system can present to vSphere a LUN bigger than 16TB so that I could create the big VMFS volume.

There is a known 16TB LUN size limitation from NetApp. But what about other vendors?

Thanks in advance.

There are indeed still storage system with a 16TB maximum LUN size. I assume that Netapp's 16TB maximum is due to a file system limitations on which they store the LUNs.

Anyway, the storage vendors usually have the max. LUN size for supported operating systems in their documentation, and even less expensive systems support LUN sizes with 256TB, or more.
