Off to the races

With SAS® Grid Computing, the IT team at SunTrust can meet any emerging business requirements

Sterling Green is Vice President of Business Intelligence, Delivery Services, Enterprise Data and Integration at SunTrust – a lengthy title that requires him to wear many hats.

Green arrived at SunTrust over three years ago, tasked with establishing a SAS Center of Excellence that could build best practices and support the entire SAS end-user community. Additionally, Green was challenged with leading the effort design a road map for SunTrust's next-generation computing platform. The requirements were demanding—a stable and robust architecture that would meet the existing and emerging business processes and facilitate risk management and regulatory compliance.

SAS Grid Manager increases our analytic processing power by allowing us to put all our resources in a grid environment and better manage the different work cycles.

What Green encountered were outdated hardware platforms, inefficient use of compute resources, siloed data and a limited ability to scale up. Additionally, the fledgling SAS Center of Excellence was faced with supporting the enterprise-wide SAS user community on three separate platforms: PC, mainframe and an aging HP-UX environment.

One major inefficiency that Green faced was that existing HP-UX servers were assigned to particular groups within the organization – one for the marketing group, another for the mortgage team, a third for consumer banking and so on – creating a sense of ownership within the various lines-of-business and a hesitation for sharing processing resources and allowing anyone else into the job queue. Waits could be long, especially for servers assigned to groups that run daily automated jobs. Server workloads were poorly managed as well. Some of the servers had reached maximum capacity and suffered from latent demand, while other servers were grossly underutilized.

Making more room

To make the situation worse, "When another new group of potential SAS users wanted to jump into the SAS pool, there was no room for them," Green says.

The need for additional computing capacity continued to grow as new users were brought on board and the demand for processing larger and more complex data sources increased. For example, the risk management department was brought into the SAS environment to do in-depth modeling and regulatory compliance, while the marketing department increased its demand for performing well-defined customer segmentation analyses in a more timely manner.

Optimal processing

Workload management was another primary consideration. SunTrust needed to maximize overall throughput by optimizing the processing of multiple applications and jobs. Centralized administration makes it possible to enforce business rules and policies, determine job priority based on the needs of different users and, in general, deliver better service levels.

Highest-priority jobs are guaranteed to run in the least amount of time. If all resources are busy, SAS Grid Manager will suspend lower-priority jobs and free up the necessary resources.

Parallel processing was another big consideration for SunTrust. The marketing analytics group at SunTrust uses SAS® Enterprise Miner™ and SAS® Enterprise Guide® to model cross-sell, up-sell, attrition rates and other activities for all lines of business. Early testing results show improved processing times, and because both products are tailored for parallel processing, the marketing analytics group expects additional improvements when the grid-enabled environment is fully deployed.

And yet another benefit is a clustered file system. In the past, business analysts at SunTrust often spent more time moving data from one server to another than doing actual analysis. They now gain a single version of the truth without federating the data across different lines of business within the bank.

Positive early feedback

It's obviously a big challenge to move users who are comfortable in their current environment – mainframe, PC or UNIX – into a newer, more flexible, interactive one with SAS 9.3.

That's why the SAS customer loyalty team for SunTrust was engaged to provide training on SAS 9.3 products to bridge gaps and encourage more SAS usage.

Initial reactions have been positive. As an example of the immediate feedback Green received, one user said that a job that used to take 10 hours to run on HP-UX ran in only about 2 hours on the new development environment based on SAS Grid Manager. With positive early results in the testing phases, Green anticipates SunTrust will really be off to the races when the production environment is fully online.
