Yeah, it's LVM-based so 2TB per extent, you can have up to 32 extents per datastore however, just open the datastore and add a second extent. Beware however that although v4 is better at dealing with extent-loss not killing the whole datastore it is still possible, it's not actually good practice to have particularly large datastores either, although it comes in handy every now and then.

  • the prob i am running into is dell perc6i is exposing 6*600gb as 2.87 in R5 which esx4 cant install. is there a way by changing block size? – JMS77 Apr 23 '10 at 15:11
  • Ah, your actual presented LUNs have to be in 2TB chunks. – Chopper3 Apr 23 '10 at 15:37
