Bit by bit, 64-bit processors catching on

At Fortis Health, servers powered by 64-bit Intel processors are used to run business analytics on - a capability the health insurer says will help keep it one step ahead of the competition. But Roger Jones, senior vice president and CIO at the Milwaukee firm, isn't looking at Itanium through rose-colored glasses.

Like many users, Jones says he sees the benefits of the stepped-up processing power and expanded memory capabilities of 64-bit Intel processors, but he also sees a technology that is still in its infancy.

"If we're trying to collect data to understand how to better deliver healthcare to a group of people, if it's not time-critical, if it's not transactional, then we're more focused on running those things on 64-bit," he says. "We're not at a point yet, though, where we're comfortable enough to put those [customer-facing] databases on [a 64-bit] machine."

Although 64-bit RISC-based systems have been widely used in research labs and academic institutions for high-performance computing, the newer Intel-based 64-bit machines are making their way into corporate data centers supporting data warehouses, business analytics, and even file and print applications. Still, Intel's 64-bit chip, Itanium, is now found in fewer than 5% of all servers shipped, analysts say.

Itanium's move into the corporate mainstream is slow because many IT managers are waiting for greater industry support of 64-bit computing. It hasn't helped that Itanium's path has been a tough one. The first and second generations of Itanium failed to meet expectations, and vendors - and users - are hoping the third generation of the chip, code-named Madison and officially released last week, will finally meet their needs.

Today, the number of enterprise applications that run on Itanium is small - around 100, while 64-bit RISC can run thousands. Itanium's arsenal is growing, though: In just the last few months, for example, Microsoft rolled out a 64-bit version of its SQL database, and independent software vendors such as SAP and Lawson have announced that they will support Itanium 2 with their applications.

Systems vendors also are starting to grasp the idea that 64-bit computing can play a role in corporate networks. They are rolling out boxes based on Intel's Itanium processors to expand their 64-bit repertoire beyond their proprietary - and typically more expensive - RISC architectures.

Advanced Micro Devices' new 64-bit chip, Opteron, has garnered some attention from systems vendors. The chip is based on Intel's x86 instruction set with 64-bit extensions, meaning it can run 32- and 64-bit applications simultaneously. Itanium runs 32-bit applications with some degradation, but Intel executives say that concern has been addressed in the latest release. IBM is the only major systems vendor to announce support for Opteron, and demonstrated a server cluster based on it at the ClusterWorld Conference & Expo last month.

Dell has introduced an Itanium-based server, although executives say the company's focus is on the high-performance computing community until 64-bit computing in corporations becomes mainstream.

At the same time, early corporate adopters of Itanium say there is no reason to wait. They say they already are reaping benefits from Itanium-based servers and predict that it won't be long before 64-bit boxes become the norm.

"There may not be a whole lot of applications built on 64-bit today, but if we look at this story about 36 months from now, I would guarantee you that 64-bit will become the way of the land," says Jeff Cohen, CIO at JetBlue Airways in Forest Hills, N.Y. "In five years you probably won't have any database applications running on 32-bit, because 64-bit will become so highly commoditized."

Cohen says he has had no problems since he began beta-testing Microsoft's 64-bit SQL Server last fall. JetBlue's frequent-flyer application has been running on the 64-bit SQL database on an HP rx5670 Itanium-based server since December. "We saw major improvements," he says.

Not only was he able to consolidate the frequent-flyer application from two servers onto one server, but he also found that the application used only about 15% of the box's processing power at the application's peak, as compared with consuming more than half of the available resources on the two ProLiant boxes it was running on previously. What's more, the application performed better, he says.
