Hey guys. I've been looking to build a surveillance/file server for my office, but I am running into issues with the raid controller overriding my motherboard's raid controller. The controller I am using is a Highpoint 2300 that controllers 4 HDs at SATA II speeds. Since the explanation of configurations is somewhat of a length process, I copied what I have already sent to Highpoint to describe the issue. I have read many testimonies that Highpoint doesn't ever respond to support requests, so I am posting here as well. ================================ Problem Description: BIOS/Firmware Version: _v2.2__ Driver version: _N/A___ WebGUI version: _N/A___ Serial No: _XXXXXXXXXXXX_ Purhcase Date: _12-26-2012_ Purhcase From: _Newegg.com_ Operating System: _Windows Server 2008 r2_ Motherboard Model: _Gigabyte GA-A75-UD4H_ System BIOS version: _F7_ System memory size: _8 GB - 1866 MHZ DDR 3_ HDD Model: _4 - Western Digital Red 3TB- WD30EFRX-68AX9N0__ HDD Firmware version: _Unknown_ RAID Configuration: __Raid 5 (4 Disks - 4 WD Reds)_ Other configuration information: 2 additional 120 GB SSD HD OCZ Vertex 2 (Raid 1) - OS Drives Intended Configuration: Surveillance/File Server OS is installed on Raid 1 SSD HDs. Raid for this configuration is controlled by the on board raid controller. File/Media Storage will be utilized in a Raid 5 sequence. The raid configuration is Raid 5 and is controlled by the Highpoint 2300 card. Both controller configurations have already been programmed separately and correctly. Both configurations are able to function apart from one another. Problem: All signs indicate that the Highpoint Raid card is overriding the motherboard's raid/hd controller when both controllers are enabled. The SSD raid 1 configuration runs smoothly until the card with the raid 5 is inserted back the system board. Typically, without the Highpoint raid card, the motherboard runs through a controller initialization prompt similar to Highpoint's bios menu. Also, the SSDs are recognized within the motherboard bios. After inserting the pre-configured (Raid 5) Highpoint card into the PCI-E slot and rebooting, the raid 1 SSDs are not recognized within the motherboard's bios, nor does the motherboard raid controller prompt become apparent. The system then hangs looking for an operating system ("Loading Operating System") upon which it never does. I then attempted to remove the raid initialization setting within the motherboard's bios. The 2 SSD hard drives are recognized individually but only when I disable the onboard SATA(or AHCI) and run the SATA SSDs in IDE Native mode (which generates much lower speeds). I suppose the main cause would have to do with Highpoint's invasive bios management system. It seems to pop up around the same time that the motherboard's raid management pops up. ========================== I'm kind of surprised I wasn't able to find much documentation on this sort of problem, but haven't. Please let me know if anyone has ran into a similar issue.
