If you really want some lols The Register and others are reporting Microsoft's Azure secure storage service was badly affected because a critical SSL certificate was not renewed/deployed on schedule:

http://www.theregister.co.uk/2013/02/22/azure_problem_that_should_never_happen_ever/

It never ceases to amaze me the number of top level organisations who do not regard SSL certificates as a critical asset and will allow issues like this to occur.

If this is indeed true, and it fits from my experience (only Storage can take everything offline for nearly 3 days, with complex VLAN Networking problems second.) Then it looks like this was not a well engineered solution, or alternatively  hit bugs in the XIV Storage Array which they needed to get programmers to resolve. 

If the comment from Computer World is true, then I would have expected IBM to have a second XIV Storage Array which they would have been doing snapshots to, and could have failed over to, before they did the hardware upgrade on the primary XIV Storage array, then after testing they could have fallen back to the primary and upgraded the secondary array.

It appears IBM only run 1 storage XIV SAN Array in that case. 

I know of clients in the graphics industry which buy two of these for exactly these reasons, so if IBM didn't have a second one you wonder how cheap they really are.

This is of course all speculation - as I have no insider information, just experience working on a range of SAN's. 


Someone else there in the comments later rebuffed the notion of them using an XIV, so perhaps they were using an SVC or another of their higher end systems.

Personally I don't see why IBM should have been doing SAN mirroring if it's not part of the product spec. Pretty much every SAN has at least two storage controllers/processors and when you perform upgrades etc the one takes over while the other is temporarily out of service.

Sure providing inbuilt 'ass covering' would be nice, however it would then also price themselves out of the market as there are a number of providers offering VMware vCloud vDCs.

It's great if companies recognize that a single copy of data is not enough, and if they understand the difference between DR, Backups and Archival storage, RPOs and RTOs, however in the APAC region everything seems to be bought based on price with features/functionality suffering as a result.
