The Reseller Option Kit (ROK) is a software distribution option that enables you to order tuned and certified Microsoft server software separately from OEM servers so that you have more flexibility to deliver customized server solutions.
Each ROK is another server option—like memory or hard drives—that you specify when you order servers. You can install the appropriate ROK on your customer’s preferred server model to address any combination of hardware and software.
Your customers still enjoy the same great performance of OEM-tuned drivers for Microsoft software, because each ROK is carefully matched to a specific server brand.
