Life is certainly a bit odd in the storage world at the moment.
Today IBM announced automated storage sub-LUN tiering in the DS8700; so since EMC announced FAST both 3PAR and IBM have announced and are shipping product before EMC? Although IBM's appears to be chubby chunks; not chunklets more chunkosaurus!
So from IBM, you can hedge your bets with regards to storage tiering
1) Tiering is rubbish, you only need one tier and one type of disk i.e XIV
2) Tiering is rubbish, but you need more than one tier at the moment and we can speed things up with a big read cache i.e nSeries aka NetApp
3) Automated tiering is the way to go i.e DS8700
So which ever philosophy you subscribe too; you can buy from IBM. And if you want something to bind them all together, you can also get an SVC.
And then we have EMC; storage virtualisation was rubbish, what you want is federation! What you do is you get all your arrays and you federate them behind an appliance. But if you want NAS or Object Storage, you're going to need a different device.
And then our friends at NetApp; that EMC fragmented storage stuff, that's rubbish! What you want is unified storage platform! Manage all your protocols from a single operating system. What's that? Object Storage? You want Object Storage? Really, ummm...okay! Here's a company we've just bought; integrated into our operating system? Ummm, no...not really since you ask. But I'm sure it will be, someday.
HP? Well we can make it all...we have all our own technology, we've bought just about everyone and it'll all be integrated someday. Just don't ask us who makes XP and SVSP. Please!
Knock, knock....Hu's there? Is there anyone there? Are you sure? I'm sure HDS now stands from Historically Did Storage.
It's like watching monkeys bashing away at typewriters at the moment! I'm sure someone will save us but I'm not sure who at the moment.
