There are a few different possible RAID setups on the S5520HC. Run the wizard at http://www.intel.com/support/motherboards/server/sb/CS-030410.htm to make sure you're getting the right tool and drivers.
I am well beyond the information at that level. I have the correct configuration and the raid arrays working and the bios level. I have already devoured the information available
I have SATA raid, SW RAID, SATA RAID 5 Activation Key installed, two arrays one for boot at raid 0, 4 in a raid 5 set, and 1 as hotspare.
Correct Chipset, Controller and Drive Raid drivers all installed.
As indicated the problem exists in the Web console software...
You mention "Intel Rapid Raid technology". Is that Intel® Rapid Storage Technology and are you using the Intel® Rapid Storage Console? If so, your S5520HC ON-BOARD LSI RAID is ESRT2 and you should be using the Intel® RAID WEB Console 2 Utility for your operating system.
RST and ESRT2 are two different software stacks and the different consoles don't support the other software stack.
I thought this was clear enough
When using the RAID console 2 app Bacground initialisation does not progress beyond 0%
The comment on Rapid Raid was a LAMENT that things do not always seem to improve - Rapid Raid software is elegant and Nice and works, and ESRT II Raid Web Console 2 is a load of rubbish that does not work ,poor graphics, poor documentation, poor functionality.
Is that clear now
The Problem is in ESRT II Web Raid Console 2 software
