IWill DK88 Opteron Motherboard

Although IWill has gone out of business, we decided to use one of its server motherboards for this project. The DK88 is based on Nvidia’s nForce Professional chipset and it offers both PCI Express and PCI-X slots.

AMD Opteron 875

We still had a dual-core Opteron 875 in our shelves and decided to use this one for this project. Since we used a RAID controller with an on-board XOR unit, such a powerful processor would not have been necessary. However, we decided to avoid any possibility of creating a bottleneck.
