Can you really squeeze 96TB in 1U ?
Yes, that’s a clickbait title. But technically it’s possible if I dropped all drive redundancy… I recently saw an advert for a server that was just too good to be true. It promised to bring a huge amount of storage and future options in a quite hard-to-believe 1U. The price it was on offer for…
