Fully-Buffered DIMM technology in HP ProLiant servers

Abstract
This paper describes the features, benefits, and challenges of Fully-Buffered dual inline memory module (FB-DIMM) technology. It also provides rules for populating FB-DIMM slots to achieve maximum performance in HP ProLiant servers.

Introduction
HP ProLiant servers provide balanced system architectures that deliver peak performance per watt of power. A balanced system architecture is one in which the three main server subsystems—processing, memory, and I/O—interact efficiently to maximize CPU performance. The introduction of dual-core processor technology challenged HP engineers to improve the performance of the memory and I/O subsystems to maintain system balance. Engineers overcame the performance bottleneck of the parallel I/O bus by migrating to a high-speed serial interface with technologies such as Serial-Attached SCSI, Serial ATA, and PCI Express. Likewise, some memory subsystems are migrating to high-speed serial FB-DIMM technology to deliver scalable bandwidth and memory capacity that is not possible with traditional DIMM technologies.
The paper describes the barriers that limit memory capacity and performance of servers that use traditional DIMM technologies. This paper also describes the operation of FB-DIMMs and summarizes the benefits and challenges of using FB-DIMM technology.
