I know some information  about HDD, partition.
But may be not enough
I know:
MBR has max Partion = 2TB
Ext3 can be 32 TB a partition
GPT can be 18 extrabyte
...

I need more information about How format in Window and Linux with largest disk, partition?
(For example with SAN...)

Thanks in advanced!

MBR has a maximum disk size of 2TB, you can stitch several of them together using dynamic disks (yeuch) to get a partition greater than 2TB and format that using NTFS.

SAN may have a maximum LUN size of 2TB or less, you have to check the model and firmware version. e.g. MSA1000 max LUN size 2TB, HSG60 max was 512GB.

I think 2TB is small, because 32TB is limit of ext3 format in Linux?

and no reason for that limit?

Now, with MBR, partition entry is 4byte = 32 bit ---> 2^32 ~ 4billion sector => 2TB (with 512 byte/sector)

If not use MBR, but use mordern format, I thing the limit much larger

May be replace MBR by GPT ?

So I wander mordern SAN can has very lager LUN, not only 2TB, because the enlagerment problem is not compicated?

VMware ESX doesn't like a LUN bigger than 2TB (it will misreport size)
I was suggesting that if he just needed multiple 2 tb partitions, not 4tb of space on one drive letter, he could also do it in vmware.

I'm desinging a system like http://rapidshare.com/, megashare , ...

I want to know the Infrastruct of Rapidshare

If they use SAN ? I think no because SAN is expensive, not optimized solution?
