LUN Vs Data Store
Dear All,
In my capacity planning process brfore going to server consolidation with VMware, I knew that :
ESX can detect data store with max size 2 TB
1 Lun =1 Data store
max 256 LUN per host
So what if the VMDK will excceed 2 TB (for file server for example) ?? how it will be located in Data store.
I am totaly new new to virtualization and i need to know all the limitation before i proceed

if you wanted to create a disk larger than 2TB-512bytes you would use a RDM.
You can't have a VMDK more than 2TB (-512 bytes. It won't be located anywhere, it simply won't work.
Now that being said with version 5.0 you can have a datastore of up to 64TB. Which when attached would look like a second hardrive. Many OS's have an issue with the root storage being more than 2TB anyway. In 4.0 I did successfully create a software RAID out of multiple 2TB datastores to create a bigger drive.

Thank you all for your prompt responses, we can conclude that :
In ESXI 4 (my cuurent version) Datastore maz size is 2 TB
In ESXI 5 Datastore maz size is 64 TB
but in both cases the maximum size for the VMDK is 2 TB
Do you know how can i upgrade from version 4 to 5, i have alicense for VMware vsphere 4.1 essential plus, it will work with ESXI 5 or I need to purchase any other license.

How you upgrade is another question.
You are correct in your description...
If you do not have a valid license for ESXi 5.0, your existing 4.1 license will not work.
