Fujitsu/Fujitsu Siemens Computers PRIMEPOWER Enterprise Servers

designing all of Fujitsu's Intel-based servers worldwide. These are the PRIMERGY servers. FSC also

settled on Fujitsu's SPARC/Solaris servers as the strategic follow-on to its Siemens RM servers, which

used MIPS RISC processors and ran the Reliant Unix operating system. The PRIMEPOWER servers are

designed and manufactured in Japan, but FSC has had considerable input to the software, thanks to its

previous Unix expertise. It developed the PRIMECLUSTER and low-level server management software

for PRIMEPOWER, for example.

FSC has been selling PRIMEPOWER servers (or the GP7000F as they were previously known) in EMEA

since 1999. Siemens was already an established player in the Unix market, so the PRIMEPOWERs

inherited the European vendor's existing sales and support channels. The PRIMEPOWER servers have

sold reasonably well, selling into existing Reliant Unix customers as well as new customers. The latter

mainly consists of existing Sun customers, who are looking for a second source. Even so, FSC trails the

top three Unix vendors by quite a margin. In 2002, FSC's share of EMEA RISC/Unix server market

revenue was 5.2 percent, compared with Sun at 35.1 percent, HP at 34.8 percent and IBM at 19.8

percent.

The bottom line is that the PRIMEPOWER business is small compared with the top three Unix players,

but it is growing from an almost startup position in North America. That, however, affects its overall

standing in worldwide terms. The combined Fujitsu/FSC had a 4.1 percent share of worldwide RISC/Unix

server market revenue in 2002. It's fair to say too that PRIMEPOWER is still restricted to the major global

markets—Japan, EMEA and North America. Outside of those areas, PRIMEPOWER's availability and

take-up has been very limited.

Technology

If Unix market share and awareness belie the true size of Fujitsu/FSC as vendors, then what about the

product itself? What other attributes does it have besides binary compatibility with SPARC/Solaris?

The PRIMEPOWER servers' most compelling attributes derive from their advanced technology. The

1.35GHz SPARC64 V chips are around 35 percent more powerful than Sun's 1.2GHz UltraSPARC III

chips. Sun's 1.2GHz UltraSPARC III is the fourth iteration of its chip, whereas the 1.35GHz is the starting

point for SPARC64 V. Fujitsu's technology and its advanced chip manufacturing capabilities are proven,

and it has a good record of delivering on its technology promises. Whereas Sun's chips tend to improve in

small but frequent increments as its chip manufacturer's capabilities and yields improve, Fujitsu offers

fewer but more significant enhancements, restricting enhancements to an annual rather than quarterly

cycle.

Fujitsu has not only produced a reasonably powerful processor in SPARC64 V, it has complemented it

with a crossbar and server design that offer very high levels of sustainable bandwidth. The two 66.5

GB/second XA crossbars in the PRIMEPOWER 2500 provide sustainable 133 GB/second data rates for

both remote as well as local memory access. That compares with data rates on the Sun F15K's crossbar

of 43.2 GB/second.

That's an important point for the overall scalability of the system. Sun achieves its highest throughput only

if all memory accesses are local and memory latencies increase significantly (by up to 2.1: 1) when CPUs

have to access memory on remote CPU/memory boards. The PRIMEPOWER's higher bandwidth over all

of its two-tier interconnect, however, translates into better online transaction processing scalability for very

large configurations. Online transaction processing (OLTP) applications scale well when memory

latencies are low and relatively stable across the whole system.

In addition to the high-bandwidth crossbar, the PRIMEPOWER 2500's maximum I/O bandwidth is nearly

6x greater than the Sun Fire 15K's maximum. The PRIMEPOWER 2500 not only supports more
