Generally the drumbeat of messaging from HDS is as constant as a metronome: array-based virtualization is the answer. Storage virtualization will heal your environment, bring about peace in the Middle East, and solve global warming.
So when an HDS exec writes a piece on his blog about who might not benefit from storage virtualization, it’s definitely worth a read.
David Merrill, storage consultant and solution architect with HDS since 1996, recently got back from what sounds like a rather thorny customer engagement in Korea. The customer, who is not named, wanted to extend its XP array’s virtualization to legacy systems (the XP being a rebranding of HDS). During a TCO analysis, Merrill writes, “Total purchase cost for the virtualization solutions was, as you can guess, less than a monolithic, but the 4-year TCO costs were higher” due to power and cooling costs, and maintenance costs with legacy systems (“when virtualizing older systems, the old hardware maintenance comes along too,” notes Merrill).
The user still went with virtualization because there was a “tipping point” with 20% storage growth over the next three years during which the virtualization will become more cost effective. “Moral of the story, be sure to look at many factors when considering different architectures. Just because you can virtualize does not mean that every old system needs to be kept around indefinitely…Your mileage will vary,” Merrill concludes.
Wonder what Mr. T would think of that.
