Submission + - Benchmarking power efficient servers

modapi writes: "According to the EPA data centers — not including Google et. al, — are on track to double power consumption in the next five years. Forget about global warming, that is a lot of expensive power. Can we cut the power requirement? We could, if we had a way to reliably benchmark power consumption across architectures. Which is what JouleSort: A Balanced Energy-Efficiency Benchmark (PDF) by Suzanne Rivoire, Mehul A. Shah, Parthasarathy Ranganathan and Christos Kozyrakis tries to do. StorageMojo summarizes the key findings of the paper and contrasts it with the recent Google paper "Powering a warehouse-sized computer". The authors use the benchmark to design a power-efficient server and to consider the role of software, RAM and power supplies in power use."

Submission + - Everything You Know About Disks Is Wrong

modapi writes: "Google's wasn't the best storage paper at FAST '07. Another, more provocative paper looking at real world results from 100,000 disk drives got the "Best Paper" award. Bianca Schroeder of CMU's Parallel Data Lab paper Disk failures in the real world: What does an MTTF of 1,000,000 hours mean to you? (pdf) crushes a number of (what we now know to be) myths about disks such as:
  • vendor MTBF validity
  • "consumer" vs "enterprise" drive reliability (spoiler: no difference)
  • RAID 5 assumptions
A good summary of the paper's key point is at StorageMojo."
