C. Installation steps for large volume (TB)
Introduction:
Sans Digital AR108X SAS RAID are capable of supporting large volumes (>2TB) on all product lines.
When connecting controllers to 64bit OS installed host/server, the host/server is inherently capable for
large volumes from the 64bit address. On the other side, if the host/server is installed with 32bit OS,
user has to change the block size to 1KB, 2KB or 4KB to support volumes up to 4TB, 8TB or 16TB,
for the 32bit host/server is not LBA (Logical Block Addressing) 64bit supported. For detail installation
steps, please refer to following steps below.
Step 1:
Configure target
1. Prepare the hard drivers which capacity is over 2TB totally. Follow the example in chapter 3 to create
a VG/UDV. Then attach LUN.
Tips : If the OS is 64bit, user can set the block size to any available value. If the OS is 32bit, user must change
the block size to larger values than 512B. There will be a confirmation pop-up message when VD size is
over 2TB.
