Let's see
1. IBM performance leader? Falling off my chair laughing....
For example, when were they last #1 in vmark performance for VMware environments? Dell obviously leads here in just about every category and has done for a long while now.
Dell largely leads in the measurements that most matter to customers: price-performance per watt, performance per watt.
2. Green leader? Dell again. Dell's leadership in price-performance per watt
3. Scientific survey? 187 customers is not a particularly scientific sample.
4. Customers speak with their dollars. Dell is growing servers market share faster than overall market. Are HP, IBM, Sun ?
5. Technology leader? Dell again. Compare Dell blades to IBM Blades and you'll see technology that actually saves customers money and reduces their ongoing management costs.
6. Sun's not even worth mentioning here - they have a microscopic X86 market share and fall under the other category with Supermicro and white box manufacturers.
7. Roadmaps? Remind me again how many times IBM has forced customers to update power supplies in their blades to accomodate new server formats. Bad planning, in comparison to HP, Dell who pre-designed blades to accomodate multiple generations of Intel and AMD chipsets.
CONCLUSION: article sucks.
