You've read a bunch of articles online, on reputable-looking websites, telling you that you must drain your water heater to flush out the sediment.

Someone gets up on YouTube and gives a tutorial on how to clean out the sediment from your water heater. An eight-node, dual-socket system with GPFS starts at around $8,000.This thing happens in the DIY blogosphere. According to IBM, GPFS runs on AIX 5L on Power processors, on Linux on IBM AMD and xSeries systems, and on Linux on Power platforms. It is capable of supporting multiple terabytes of storage and more than 1,000 disks within a single file system. IBM's file system has its roots in Unix, where it was used starting in the 1990s on clusters of Unix servers. It is designed for bandwidth-intensive applications such as computational fluid dynamics, crash analysis, structural engineering, flow simulation and interactive 3-D visualization. GPFS provides a scalable parallel file system that can support hundreds of terabytes of storage within a single file system. So far, the National Energy Research Scientific Computing Center has implemented GPFS on a 320-node Linux Networx cluster. Linux Networx clusters are currently available with the Lustre File System, but customers wanted a choice of open-source file systems. GPFS will also be available within Linux Networx's Advanced Technology Clusters. Linux Networx last month expanded its Supersystem range with a midrange LS-1 Supersystem and a high-end LS/X supercomputer. Linux Networx will integrate GPFS with its Linux Supersystems and will sell, tune, optimize and support GPFS. The agreement between IBM and Linux Networx is the first for IBM and follows Big Blue's move last week to open up the source code to GPFS to third parties. Linux Networx announced last week that it had signed an OEM agreement with IBM to distribute IBM's General Parallel File System (GPFS).
