IBM
"A year ago IBM would have been the third-ranked vendor, but its revenues fell 7.2 per cent to $866m, giving it fourth place. Not so Big Blue is failing to keep up with modern storage technologies and its ageing product set has less and less appeal to customers."
I don't agree with the analysis of the cause. This has little to do with the products (XIV / V7K are fine and along with their SVC capability offer distinct advantages) and a lot to do with the fact that IBM decimated its internal sales / pre-sales organisation because it thought it could rely on the "channel". Fools.
