Micro servers have the ability to significantly reduce power through integration of server motherboard functions particularly for common tasks such as web servers, search engines, on-line transactions, and video-on-demand. Innovation in low-power servers will be one of the drivers of growth in the overall IP market over the next few years.
Micro server system-on-chip designs involve challenges such as determining trade-offs between low power vs. high performance operation; need for cache coherency; integrating high bandwidth interconnects that are scalable to many cores; implementing heterogeneous processing HW accelerators; addressing Reliability-Availability-Serviceability (RAS); and incorporating technology that is portable to future design processes. Network access to a high performance fabric such as Ethernet along with I/O expansion using PCI Express root ports and devices supporting single root I/O virtualization (SR-IOV) is critical for data center server virtualization.
