Is there a limit windows server 2008 to how big your storage pool/partition size can be?

Using MBT the limits are (I understand) the same as Windows 2003 (see here for details):

  • Maximum simple partition: 2TiB
  • Maximum non-simple volume (i.e. single NTFS volume across multiple partitions/disks): 232−1 clusters. So with 512 byte clusters that is ~16TiB, but could be significantly larger (e.g. 64KiB clusters gives ~256TiB).

With GUID Partition Table (GPT), the limits are 264 clusters (in theory), but it is not clear if there are any practical limits significantly below this for the volume size in general. A single parition GPT volumes is limited to 18EiB (i.e. 18×1024×1024TiB). Individual files are limited to 244 bytes by implementation limits from the NTFS format limit of 264.

+1 Short answer to the question: no (using GPT) ^^ – Oskar Duveborn Aug 3 '09 at 9:36

The maximum NTFS volume size is ~16 TB. Just saying!

That's close to effective right? Anyone who's tried to manage anything that large, and more specifically migrate something that large, will agree that may as well be 1 PB. – mrdenny Aug 3 '09 at 5:54
Hypothetical it could reach 16 exbibyte (16 x 1024PB). Unfortunately I cant prove it :( – SZayat Aug 3 '09 at 6:22
-1: Not true with GPT disks. – Richard Aug 3 '09 at 8:56
+1 to compensate for Richard contradicting what xe xyrself wrote above, which is that that Microsoft's NTFS implementation uses 32 bits for cluster numbers which is irrespective of disc partitioning scheme, and downvoting this based upon an erroneous self-contradiction. – JdeBP Jun 12 '11 at 0:42

If the volume is MBT then 2 TB is the limit. Otherwise it's effectively unlimited.

-1: Only true for a specifically limited case (single simple partition with 512 byte clusters). – Richard Aug 3 '09 at 8:57
