VPS.NET Japan cloud test failure – Success!

[blackbirdpie url=”https://twitter.com/vpsnet/status/116838472219770880″]

Today at around 06:30 EDT, VPS.NET engineers did a test failure at their recently launched Japan cloud and it went really well!
No downtime, no data loss, nothing. Exactly as it should work. Kudos to the VPS.NET team! I really hope that they have found the perfect solution for their SANs and that they will begin rolling-out the new technology to their other SANs soon.

Below is the output of sar, about an hour and a half after the test. The lines that indicate that something was going on (i.e. the test failure) are highlighted.

    That is a great sign – good statistic catch. I hope that this new SAN structure will make a good solid platform at the other datacenters. Atl-E has been rough lately. Here’s hoping that things will be looking up!
