Happy birthday to you!
Happy birthday to you!
I was working on one of the storage teams at a very large company, though not working directly on the technology (mostly just workflow improvements). Never had to get my hands dirty with this stuff, but one of the side projects that I would hear about occasionally was bringing in three DMX 4's to move 1.4 PB onto. Since each DMX 4 can handle 1 PB alone, what kind of factors would drive the decision to get three? Future capacity management seems like an odd answer to me, since the forecast was not anywhere near that in for the near future because other data centers were going up. Might this be for some kind of redundancy? Is it possible for one of those DMX's to completely fail? Is it seriously like one singular, monster storage array?
