CONSIDERATIONS FOR RAID VOLUME CREATION

! Your RAIDBank4 is capable of creating large logical volumes (LUNS) in excess of 2 Terabytes. Large LUNS (>2TB) must be supported by the host bus adapter and the host Operating System to be usable. Windows 2003, Vista, Windows 2008, Mac OS X >10.4.8, and Linux distributions with

appropriate kernels all support large LUNS. Windows XP and prior cannot address large LUNS natively over USB, and must use eSATA host bus adapters that have RAID support to be usable. MicroNet offers such host bus adapters- consult your MicroNet authorized reseller for more information.

1. Quick Volume/RAID Setup

Quick Volume And RAID Setup is the fastest way to prepare a RAID and volume set, and needs few keystrokes to complete. This function creates a single RAIDset and one volume set, and you can modify the RAID level, stripe size, capacity, and designating drives as Hot Spares. The created RAIDset will have the following properties (default setting values can be changed after configuration is completed):

Parameter	Setting
Volume Name	Volume Set#00
Host Channel/ Drive Select	SATA/0
Cache Mode	Write Back
SATA Xfer Mode	SATA300+NCQ

1.1Specify desired RAID level and spare configuration

1.2Select volume set capacity size. When choosing >2TB support, make sure the host operating system can support the volume (see “Consideration for RAID volume creation” above)

1.3Select stripe sizes for the current volume set. This parameter specifies the size of the stripes written to each disk in a RAID 0, 1, 10, or 5 volume set. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB. A larger stripe size provides better-read performance, especially if your computer does mostly sequential reads. However, if you are sure that your computer does random read requests more often, choose a small stripe size.

1.4Specify foreground or background initialization. Background initialization will make the volume immediately available to host access, but initialization will complete slower. Foreground Initialization must be completed before the volume set ready for system accesses, but will complete quicker.
