Vacation from overload
Last month, Transat replaced the Sun Fire 6500s with the two Sun Fire 6900s in the production environment. Once the peak holiday season is over, in January, the company will re-evaluate its performance and capacity needs and decide whether to upgrade all processors to the new UltraSPARC IV+ chips or to run a mix of UltraSPARC IV+ and UltraSPARC IV chips. Because the server architecture supports different types of chips on the same system, few adjustments will have to be made if Transat does go the hybrid route.Guillemette and Babin are now beta testing a Sun Fire V890 server with the UltraSPARC IV+ chip and are using the test results to gauge performance in their specific environment. So far, Guillemette and Babin said that they have been happy with the performance. To ensure that the UltraSPARC IV+-based server would fit well in the Transat production computing environmentand that upgrades would not disrupt operationsGuillemette and Babin deployed the V890 server in a test environment. Once the system was up, they configured the database and reservations application on the server to test their functionality. In benchmarking tests, the V890 server with UltraSPARC IV+ was able to conduct transactions in about half the time it took the Sun Fire 6900 servers with the UltraSPARC IV to finish the same job. "Sun says the UltraSPARC IV+ will provide twice the performance of the UltraSPARC IV, and were getting close to that," Guillemette said. "In a compute-intensive environment, it seems we would get that kind of performance." Guillemette said he hopes to upgrade in the near future from Solaris 9 to Solaris 10 to take advantage of the newer operating systems performance increases. The Logitours application is not yet certified for Solaris 10, and Guillemette said Accovia may be asked to participate with Transat in the certification process. In the meantime, Transat is planning to migrate its Informix database servers onto Solaris 10 as soon as the IBM application is fully certified. "The initial configuration of the 6900s will satisfy our needs for this year, and when peak season is over, we will simply order additional CPUs and add them into the same box," Guillemette said. "The 6900 servers with UltraSPARC IV+ will last at least three years in our environment if the load continues to grow by about 20 percent a year."

"The investment we have right now will be maintained, and when we add more capacity to our systems, well simply add twice as much power without increasing our licensing costs," Guillemette said. "This is of direct financial benefit to us because there is no forklift upgradewe can just keep on adding new technology."
