Appendix C: Working with Volumes over 2TB in size

Although the RTX can create data volumes larger than 2TB, operating systems cannot usually access

such volumes. This is because most systems support only 32-bit LBA (Logical Block Addressing).

Newer operating systems (Windows Server 2003, Vista, Mac OS 10.5.x) should be able to use 2TB+

volumes without difficulty. You will simply need to do one of the following two things while creating the

UDV (User Data Volume):

• Change the LBA to 64-bit

• Increase the block size to 4096

Windows

Neither of the options above will work for Windows versions before Server 2003. You will need to make

more than one UDV, each less than 2000GB in size. Each UDV also needs a different LUN.

Mac OS

Although Mac OS 10.4.x supports only 32-bit LBA, increasing the block size to 4096 will allow you to

create a 2TB+ volume that is usable by the OS.

Linux

Versions of Linux vary, but using one of the above methods may allow you to create a 2TB+ volume that

your distribution can use.
