KeyBank sees big savings by moving to Linux servers
The Cleveland bank's server costs have fallen by 80%

Cleveland's KeyBank is keeping its own bank balance healthy by moving much of its back-end infrastructure to Linux.
In mid-2004, Key, which manages $92.3 billion in customer assets, began replacing aging Unix servers with Intel-based Linux servers that are less expensive than sticking with pricey and proprietary Unix hardware. The bank saw its server costs fall by 80%, according to Dave Seager, vice president of Unix systems engineering.
As part of the project, the bank last year bought 100 HP servers running Red Hat Enterprise Linux. By 2008, Seager expects Linux to comprise half of Key's servers.
"In the last year, Linux has gone from 'unapproved for use in the building' to our platform of choice," Seager said.
When Seager arrived at Key fresh from a dot-com four years ago, getting support from higher-ups -- including the then-CIO -- to consider a move to Linux wasn't easy. Would the anticipated cost savings from Linux really offset possible issues with support, extra maintenance and uncertain compatibility? they had asked.
After culling vendors, Seager went to Red Hat Inc., which gave him "honest" advice that yielded solid cost-savings projections. "Red Hat went through our entire application stack with us," Seager said. "They were very explicit about where Linux excelled and where it had weaknesses, and where we could get the most dollar-for-dollar benefit."
Those areas included moving Oracle databases and WebSphere application servers to Linux, where "the cost savings are comical," Seager said. Meanwhile, Red Hat pointed out that switching out Windows servers already running on Intel hardware would lead to tiny cost savings at best.
Most of Key's servers are Hewlett-Packard two- or four-way boxes, models such as the 360, 380 or 585 running Intel processors, Seager said. They typically start at just $3,000, rather than $30,000 for a regular Unix server. That price difference won over Key Bank executives who were initially hesitant about the move.
"Telling them Linux was cool or the new thing didn't translate very well," Seager said. "Saying it saved x percent of our budget translated very well."
Key has spent only about $1 million on Linux servers in the past year and a half, a fraction of what it would have otherwise spent on upgrades to new proprietary Unix servers.
Featurewise, Seager only needed Red Hat to be "on par" with Unix platforms, with reliability the most important factor. So far, he said, it hasn't disappointed. Key also runs internal monitoring and system management applications on Linux, as well as Web and network servers.
