Commodity hardware seems a good/cheap option - and I don't know, this might be fine for them.
I built a couple of racks for clustered decryption using commodity hardware; after a few months "burn in" the failure rate proved to be way higher than expected. Which, when you think about it, is logical - they are running 24/7 (compared to if you were using the hardware "normally").
After having to replace three servers inside a month we started to cycle into server hardware. This was a lot more expensive up front, but is reliable and the failure rate is almost non-existent in comparison.
So; buyer beware.
Even so; it is good to see someone else hacking together their infrastructure :)
- khadim 14y agoSo far, for last 8 months, we have seen couple of SMPS failures and a motherboard. Also had issues with UPS batteries. We are learning and improving in component selections, which should further improve Failover is also managed at application layer by FOSS such as Cassandra, Hadoop, so user's have in general not faced much downtime. If we are not able to scale or manage, we will re-look and consider moving to public cloud.
- peterwwillis 14y agoI'd wager the biggest cause of failures is improper air flow. Even if you keep the room ice cold, if the servers can't push air efficiently over the HDDs/CPU and into a hot aisle, you'll get hot spots and hardware failure is inevitable.
- khadim 14y agoThanks Peter. We are getting good pointers. Will try to figure out some way to fix.
- jeffffff 14y agowhat components were you having issues with the most?
