Dellin 2003, a decision that dovetails with the company's position that powerful "big iron" servers by clusters of lower-end machines. It took HP another generation of chips and crucial supporting components called chipsets to reach a similar decision--although for different reasons.
HP believes that forthcoming Xeon chips that employ dual-processing engines, called cores, will be more popular than full-fledged eight-processor machines, said Colin Lacey, director of platform marketing for the company's industry standard server group. And for powerful machines, HP steers customers to higher-end servers with as dozens of Intel Itanium processors.
"We are not refreshing our eight-socket platforms," Lacey said. "We have determined, based on the performance we anticipate delivering in the x86 space in 2005, that the position of the eight-way will be somewhat marginalized by these next-generation four-way platforms."
HP's move makes sense, said Sageza Group analyst Clay Ryder. "Eight-way systems are a lot more complicated than single-way," he said. Beyond four-processor servers, "things become geometrically more complicated. When things become complicated, they become expensive."
Business reasons provide further incentive for HP. "When you get to that level of Xeon performance, you're starting to have systems with Itanium there that becomes an internal conflict" between different HP business units.
HP revealed its decision to skip eight-processor servers at the same time it announced two , as expected, and a new dual-processor system. Intel's latest Xeon processors, which bring 64-bit memory extensions to four-processor servers, include a lower-end model code-namedwith more built-in cache memory.
Intel and business partners plan to announce the chips at an event in San Francisco on Tuesday. Each new chip will be available in the new ProLiant ML570 G3 and DL580 G3 servers, Lacey said.
Different views of x86 servers
HP garnered $1.8 billion of the $6.1 billion in x86 server sales in 2004, and No. 2 Dell had $1.4 billion, according to market research firm Gartner. Dell and HP now rely on chipsets from Intel for all their Xeon models.
But the two other major server sellers, IBM and Sun Microsystems, believe high-end x86 servers are worth pursuing. Big Blue has its own chipset, called, that permits as many as 32 Xeon processors to be used in a single server. And Sun has chosen a partnership with Intel rival Advanced Micro Devices that will result in the with as many as eight AMD Opteron processors.
IBM and Sun have a different view of the market, though. They each have their own high-end processor families to promote--IBM's Power and Sun's Sparc--while Dell and HP prefer to use Intel processors for high-end servers.
Previously, HP created its own chipset, F8, for its eight-Xeon DL740 and DL760 servers. For lesser machines, it purchased chipsets from Intel and Broadcom's ServerWorks division. Now it's Intel only for x86 servers.
"With this introduction, we do not have a new generation of ServerWorks chipsets shipping today," Lacey said. However, he added, "We continue to maintain open dialogue" with Broadcom.
HP sells servers with four AMD Opteron processors but as with Xeon doesn't plan eight-processor models, Lacey added. "For eight-socket and above, we see the market space driven by our Integrity platforms," models employing Intel's Itanium, he said.
Dell has announced its new four-processor models already, the. IBM also announced its four-processor in February and put it on sale Tuesday. Sun discontinued its Xeon models and now sells only x86 servers using AMD's Opteron. Many other companies, including NEC, Penguin Computing, Unisys, Fujitsu and Acer also sell x86 servers.
All the new servers employ Intel's E8500 chipset, which will accommodate future dual-core Xeon processors scheduled to arrive in 2006.
New memory protection features
HP's DL580 G3 is a rack-mounted model that measures four rack units--4U, or 7 inches--in height. It employs a technology called hot-plug RAID memory that permits administrators to change a faulty memory module in a running server without disrupting operations. It can accommodate as much as 32GB of memory; a bare-bones model costs $6,849.
The ML570 G3 is similar but larger. It has 10 input-output slots to the DL580's seven, can accommodate 48GB of memory, and has more hard drive capacity. It's available as either a standalone model or a 6U (10.5-inch) rack-mount machine. Its starting price is $5,249.
HP also began selling its dual-processor ML350 G4p, which uses the faster Xeon MP processor code-named Irwindale available with as much as 2MB of cache memory. That system has a starting price of $1,539.
It doesn't employ hot-plug RAID memory but instead offers a less expensive alternative called online spare memory. With it, the machine can switch to a spare memory module if it detects that a primary one is faulty, but replacing the bad module requires that the server be shut down.
Support for this technology, unlike the hot-plug RAID memory, requires operating system support, which is available in Windows Server 2003 today and is expected in Linux by the end of 2005, Lacey said.
Four-Xeon blade servers also are under development at HP.
"Don't have anything to announce at this time," Lacey said. "We will be coming back in a few weeks with some additional products to talk about there."
