Hi,

I'm sure i have read somewhere that there is a 2TB limit on the size of a single NTFS partition when being presented to Windows 2003 Server.  Can anyone backup this view or detail what the actual limit is?

thanks

Matt

Under NTFS, the maximum size of a partition (volume) is fact 2 to the 64th power. This is equal to 16 binary exabytes, or 18,446,744,073,709,551,616 bytes.

So that should give you 18 billion GB....

2 TB looks correct to me - have a look at http://technet2.microsoft.com/WindowsServer/en/library/bdeda920-1f08-4683-9ffb-7b4b50df0b5a1033.mspx?mfr=true for detailed information (and I mean REALLY detailed)

Are you saying that windows would be able to handle single volumes in excess of 2TB?  I agree with what you stated above with regards to the maximum NTFS volume size but i'm not so sure that windows will handle above 2TB.  If the discs were basic discs rather than dynamic would this effect it?

thanks for your prompt reply.

I currently have a SAN connected with 2 LUNS each are 2 TB in size, grouped together as Dynamic disk and spanned.  The total size presented to Windows is 4TB.  2003 Enterprise R2 Clustered with 2 servers in cluster, shows it in explorer as 4TB.

just a FYI.
