Doing More with Less: Web 2.0 Consolidation the Sun Way

Web2.0 data centers are typically filled with racks of x64 servers: single apps per box--an architectural convenience, but a decision that leads to inefficiencies of utilization, power, and space. Sun has been working this challenge with a unique and effective approach for several years: chip multithreading, or CMT. First introduced with our UltraSPARC CMT-based systems over three years ago, we have consistently demonstrated that architectures with multiple cores, each supporting multiple threads at the hardware level, can introduce significant efficiencies for some application environments. Web 2.0 turns out to be one such example.

Running Sysbench Benchmark on MySQL using Solid State Drives

Sun will soon introduce Solid State Drives (SSDs) to its lineup of systems. SSDs are bound to  change the dynamics of the IO subsystem. A traditional 15K rpm disk can do around 150 random IOs a second. However a single SSD should be able to do up to 30,000 random reads per second and consume a maximum of 3W, as rated by the manufacturer. In addition SSDs can provide faster access to the data (in the order of microseconds), while traditional hard disk drives (HDDs) have access time thousands time slower (in the order of milliseconds). [The test results in this blog were updated 2/23/09.]
