Math -- Powered by Sun


Founded in 1861, the University of Washington has one of the leading mathematics research departments in the United States. Several years ago, William Stein, an associate professor of mathematics at UW, collaborated with more than 150 mathematicians around the world to build Sage, an open-source computational software program. Sage can be used to solve a wide range of mathematical problems including algebra, calculus, number theory, numerical computation and more.

Stein recently looked to expand the computational capabilities of Sage, but felt limited by the hardware the department was using to run the software. Additionally, the department wanted to increase the overall performance of Sage while also making the automated testing of the platform faster and easier. Last November, the department began evaluating new server solutions to support Sage and eventually selected a new system from Sun.

The solution included four Sun Fire X4450 servers, powered by 2.6 Ghz Six-Core Intel Xeon processors, and one Sun Fire X4540 server that runs the OpenSolaris Operating System. The department received SunSpectrum Silver support in addition to support from the Sun market development organization during the solution’s implementation.

Since deploying the Sun solution in December, the department has gained a huge increase in computing power that has significantly sped the automated testing of Sage. Stein reports that with the Sun X4450, it only takes three minutes to run the standard Sage test suite, a task that previously took at least an hour. Stein noted that “our previous infrastructure was fine, but the entire thing was only about one-third the capacity of a single Sun X4450 server.” He said Sage runs computations much faster and stated: “The whole way I do mathematical calculations using Sage is so much different now that I have this hardware.”

hi5 slashes storage costs and scales for growth with Sun solution


hi5 Networks, based in San Francisco, California, is one of the world's largest social networks with more than 80 million registered users in 200 countries. In fact, hi5 earned the distinction of being the fastest growing social network in the world when it doubled its user base in 2008, growing from 28 million to more than 56 million and counting.

The explosive growth rate proved to be a challenge, particularly because hi5 manages so much data – about 400TB and growing. To continue providing the best service to its users, hi5 needed to ensure its systems were highly available and reliable, and at the end of 2008, hi5 realized that it urgently needed to expand its storage capacity to keep up with its rapid growth.

hi5 chose the hybrid Sun Fire X4540 server in conjunction with the Solaris 10 Operating System as its system solution. The Sun Fire X4540 is a product known for its ability to run high-bandwidth applications while providing speedy access to storage and unparalleled storage density in a 4U rack space. hi5 is so pleased with the performance of the Sun Fire X4540 servers, that it plans to purchase 10 more.

hi5 said when it came to evaluating price for performance, there was no better solution than Sun. Dan Peterson, vice president of technical operations at hi5 notes that there is no licensing fee and says “Before it was costing us about $5,000 per terabyte to store data versus about $750 per terabyte now.” Peterson also appreciates the ability to now keep a tight reign on his budget by purchasing Sun storage in 48TB chunks rather than having to buy huge storage systems at four of five times the price.
