2 Agenda Server Trends Performance Power Efficiency Price Pizzabox Performance Trends Subsystem Trends CPU Memory Power Other Trends

3 Server Performance Trends,

4 Same chart, but logarithmic scale

5 Comparing Trends vs. Moores Law Moores Law is one of these 3: - Transistors on a chip double every 2 years - Transistors on a chip double every 18 months - Chip Performance doubles every 18 months

6 Server Performance Trends,

7 6 IDEAS TRENDS: PERFORMANCE March 2012 Server Efficiency Trend,

8 7 IDEAS TRENDS: PERFORMANCE March 2012 Server Efficiency Trend, Same chart, but logarithmic scale

9 8 IDEAS TRENDS: PERFORMANCE March 2012 Server Efficiency Trend, Testing Koomeys Law

10 9 IDEAS TRENDS: PERFORMANCE March 2012 Server Price Trend,

11 Pizzabox Performance Trends

12 Source: Gartner RPE2 for select HP ProLiant DL360 generations 2-socket x86 server performance in the last decade 100-fold increase

13 Server Trend: 2 socket x86 rack servers Data Source: Me Photo source: Wikipedia HP SystemPro/33 (1989) HP ProLiant DL380p Gen8 (2012)

14 Server Trend: 2 socket x86 rack servers Data Source: Me Photo source: Wikipedia HP SystemPro/33 (1989) Internal Disk Capacity Memory Capacity Clock * Cores Memory Bandwidth

15 Server Trend: Just for Reference

16 CPU Trends

17 CPU Frequency Server CPU Frequency by system announcement date, 1998 – 2012 Not including mainframe, GPUs, and other outliers MHz

18 4-Chip Server Performance by Architecture Slide Redacted from Copies

19 4-Chip Server Performance by Architecture Itanium Opteron Xeon SPARC POWER Performance (RPE2, log scale) Xeon, SPARC are moving averages Itanium, Opteron, POWER are power trends

20 x86 Processor Prices Today, Intel accounts for ~90% of x86 server CPU shipments, down from ~70% in 2006 Performance-per- dollar is capped by technology but set by competition

21 CPU Trends More stuff on chip - More and faster memory channels - I/O interfaces (e.g. PCIe) - Accelerators (e.g. Encryption, Decimal Floating Point) - On-chip GPUs and vector engines Processor power modes - Control at individual core level - Control for uncore - Additional low-power states - Turbo modes - Frequency, voltage scaling GPUs in servers Hyperscale Computing

22 Energy-Efficient Servers / Microservers - x86 and non-x86 - Vendors building server ARM ecosystem GPU & vector processors - Robust user base for specific apps Very different power efficiency curves - Optimized for energy per transaction Will consume X % of server market - Ask 3 experts, get 4 values of X Quiz: ARM & MIPS processors are already in your data center. Where??
