Re: EVA maximum LUN capacity

Hi Aneez,

Currently all EVAs have a limit of just under 2TB for a LUN (2047MB).

I think I've heard that there are plans to remove this limit in a later version of XCS, however I'm not sure when this is likely to be released.

Hope this helps,

Re: EVA maximum LUN capacity

Anyway, 2TB is a very large size for a single VDISK. Normally, you will have better performance if you create several luns and spread the load between them, even when it's a virtualized array.
