Chapter 2.
overview
This chapter describes the overall system architecture for the IBM Power System E850C
(8408-44E). The bandwidths that are provided throughout the section are theoretical
maximums that are used for reference.
The speeds that are shown are at an individual component level. Multiple components and
application implementation are key to achieving the best performance.
Always do the performance sizing at the application workload environment level and evaluate
performance by using real-world performance measurements and production workloads.
This chapter includes the following sections:
Physical system design
Logical system design
The IBM POWER8 processor
Memory subsystem
Memory Custom DIMMs
Capacity on Demand
System buses
Internal I/O connections
PCI adapters
Flash storage adapters
External I/O subsystems
External disk subsystems
Hardware Management Console
Operating system support
