A-Team Cluster Arriving Soon
With some help from the DRBD and Heartbeat communities I hope to get our new cluster up and running within a week. With this new cluster, creatively named “The A-team”, the Wasda.nl fleet gets some serious oumpf. To give you an idea, here are some rough specs. Exact specs will follow when the cluster’s fully up and running.
- SunFire x86 machines
- 2-2 mirrored fail-over setup
- 36 64-bit processor cores
- 80GB of RAM
- 2.3TB of redundant storage
- Full gigabit backbone
According to my first measurements this cluster outperforms our current setup by 240%. When we look at processing power alone the A-team outperforms it by a whopping 1530%. Plus, our uptime guarantee will match that of our hosting provider now. Last year they had 100% uptime, while we only managed to get an uptime of roughly 97%. Server upgrades won’t mean downtime anymore, we can now update nodes safely without compromising the hosted services for any longer than 15 seconds. If this cluster can keep running and we have our weekly updates as usual, we can achieve a five-9 uptime guarantee.
A word of thanks goes out to ViaViela, the company this cluster is being built for, for supporting this great project. A list of all the people and companies will follow in this post’s follow up.
