Re: hardware cost per GB isn't all
Wh/TB = Watt x hours/TB. It's the total amount of work required per terabyte of stored information for any given period of time. Pretty much a proxy for TCO for a particular amount stored after acquisition. Now figuring that out for Infinidat's gear would be an interesting data point as well.
Personally, my heart lies with Infinidat's approach even if in the real world I do not get to make the choice of gear required. Not always, anyway.
