An acquaintance pointed out that EMC has published a case study detailing how one of its divisions, EMC Corporate IT, decided to use an EMC Isilon storage system over other competing candidates:
After considering various storage solutions, EMC IT selected EMC Isilon® scale-out storage as the foundation for a new Hadoop-as-a-Service (HDaaS) offering.
My acquaintance wondered exactly which systems EMC IT evaluated before selecting an EMC array, and whether or not there was even the option of choosing a product from any of the numerous competing storage array vendors. He pointed out how embarrassing it would have been if this case study had been written by a competitor to tout its win at EMC IT.
You really have to wonder why EMC published this case study. Its customers take it for granted that the company will use its own offerings, and would probably leave in droves if it did not.
To paraphrase an old saying: “No EMC employee ever got fired for choosing EMC!”
