Maximum size for Windows 2008 boot partition

I've an intel ss4200 nas which has 4x 1.5TB drives in raid 5 giving 4.08TB's of usable space running the EMC linux based OS on it.

I'd like to install Windows 2008 server on it but I think I'd like it to be a big 4.08TB partition.

Can Windows 2008 boot from a +2TB partition?

I could have a boot drive but that would just leave me with 3 disks left for the raid.

Thanks!

if you can make the drive be GPT, you can use up to 256TB's on it

if 4k cluster sizes, 16tb
if 512b cluster sizes, 256tb

Thanks Bryon, I know about GPT partitions but I'm concerned about whether I can have a bootable one under Windows 2008.

Unless you have an itanium, then 2TB is upper limit for a bootable partition.

thanks, so subject to the hardware raid container supporting a 4.08TB array, I could have a say 50GB boot partition and the rest as data within that array and the 50Gb would be bootable?

Why would you want to have a 4+TB C: drive?

I dont know yet. I've thrown it out there to see if what others think.

I'm trying to find the best way to work within the limitations of the ss4200

OK... I just don't see a point to a 4TB+ c: drive.  I'd chop it up.

I'm not sure if the ss4200 in the BIOS will give me the option of carving it up yet. Worst case scenario, I'd like to know if Windows 2008 can boot from a +2TB partition.

Like I wrote.  It will only boot from a > 2TB partition if you are running the 64-bit version on an Itanium-class machine.  The actual limit is closer to 2.09TB, which is the maximum number of 512-bytes blocks that you can address using 32 bits.   A GPT formatted disk will let you increase the block size, but MSFT chose not to let you use a block size > 512 for a bootable device.  IF you have an X64 architecture, you can set this up for all of your disks C:\ - Z:\  but it will not let you boot from any of them.

A suggestion.  Nothing wrong with buying a small, reliable SATA-attached SSD and boot to that.  Win2K8 will run much faster, SSDs will give you a much higher MTBF then RAID5 made out mechanical drives, and it will probably more than double overall system performance.
