cool. so I have a few thousand VMs of various OSs and hypervisors, a few hundred home-built applications with an average of 10 components each, some mainframe, some ibm-i, a bunch of linux, solaris, aix, and HP-UX server, and I'm using mysql, sql server, postgres, oracle, and a couple of DB2. there may be an informix DB or two somewhere - I don't know, I manage storage. about ten different volume managers, about 30 different filesystems - and some raw disks of course. 10PB total space, it needs to be metro cluster replicated ten miles away for active/active, and async in a different state can be about a minute behind max. So, write me some software that's going to make all that work and make the storage highly available. make sure it works for everything. you're exposed to solutions that make that work, daily. when you swipe your credit card buying condoms - you have no idea how much happens so your transaction doesn't get lost, corrupted, or errored out.

> you have no idea how much happens so your transaction doesn't get lost, corrupted, or errored out. Maybe he doesn't, maybe he does - you don't know nor do I. I'm pretty sure this is how IBM salesmen used to respond when confronted with those newfangled Unix systems which were starting to appear here and there, nibbling first, then taking larger bytes out of their market share. Instead of the litany of diverse systems they'd have thrown LPARs, SYSPlexs and ESMs around but in the end it still came down to the same thing: this stuff is too complicated to be left to amateurs. They were right, in a way... until those amateurs grew their wisdom teeth and took a large part of their market away from them. Yes, "enterprise" stuff is complicated - often overly so [1] - and it has its place. This does not make it the only viable solution to these problems, something will eventually come up to eat your lunch just like IBM saw its herd of dinosaurs being overtaken by those upstart critters from the undergrowth. Maybe some smart software system which "guarantees" data reliability and availability without the need for "enterprise" storage devices? It wouldn't be the first time after all.
