> You use this commercially? For "mission critical" stuff? Yes. It passed all 100% CPU utilisation and md5-memory checksumming tests without a single fault in its cabinet. I was just idly curious about it... it's running as a backup server for something else. It's going onto its 75th day of uptime, and no process has even core-dumped on it. CPU Temperature is holding at 45 C, and these SuperMicros have passive CPU cooling (albeit with four 12,000 RPM chassis fans drawing air from the air towards the rear). Go figure. I assumed it'd have crashed and burned during my burn-in test. It performed flawlessly. I did use good quality ECC DDR-400 matched RAMs. =MB= -- A focus on Quality.
