Re: 150TB Luns no problem except....
Really....we have much larger file-systems than that...and yes on occasion we have to fsck them...it generally takes no longer than a few minutes if that. Of course, we cheat; we run clustered file-systems.
Re: Blame us customers.
I hardly know where to start; yet again, people assume commodity means some random crap that we pull out of the cupboard and install random crap on. Some people might, most corporates won't; we might start looking at ODMs if we are large enough or we might take COTS from Dell, HP or who-ever our preferred server vendor is.
Storage vendors often take advantage of the commoditisation of components themselves; hard-disks being one of the prime examples. NetApp in past have had many slides about the overhead due to making drives from different vendors look the same-size.
But businesses already run on FOSS; more than 50% of the storage vendors out there run their storage software on FOSS. Some of them get clobbered by the same bugs.
To be quite honest; the permutations of hardware actually out there when you start looking at utilising white-box storage servers aren't that large. You have to go some to go really oft-piste. Most storage arrays with a few exceptions are pretty close to being off-the-shelf servers with the vendors badge on them.
I'm not actually expecting many people to build their own servers but there are many who want to use the same servers across their estates; be it for compute or storage nodes.
Oh, I know exactly what the DS8Ks can do; in a previous existence, I worked on them and their ancestors..both ESS and VSS. In fact I have a soft spot for them but they exist for one reason only these days and that is generally to support a mainframe workload.
Yet, architecturally; they are still pretty much bog-stand dual-head array...and if IBM had wanted to, all of the features that you list, could have been incorporated into SVC, if it had started to do so about ten years ago.
If EMC can move from Power-to-Intel; IBM could have done as well. In fact, arguably moving Enginuity from Power to Intel may well have been harder. The problem for IBM is that they have left it far too long to do so and now they are saddled with multiple array families. One of which, although absolutely key to them, probably suffers from low sales due to particular niche market.
The reason for the decision are both due to the conservatism of the mainframe user-base but also I suspect to the politics which IBM's storage has been riven with over the past few years with competing fiefdoms and executive sponsors.
Re: Why would someone buy Quantum
Lets be fair, FPD and VizRT only really compete with one aspect of Stornext; that is the HSM portion. Stornext is also a clustered file-system; FPD and VizRT could both use Stornext as their clustered file-system. But Stornext is potentially being clobbered by the clustered NAS solutions that are gain more and more of a foot-hold in the market. IBM have also been more aggressive in the media space and pushing GPFS here. And of course, there is a burgeoning number of open-source competitors; some really good.
Stornext is probably Quantum's best product; it is probably the only reason anyone would buy them but who really wants it? IBM don't need it; EMC have clustered NAS products (and they could break OneFS out as a clustered filesystem if they wanted); HP have a plethora of products, this probably wouldn't stop them buying someone tho'; NetApp, well Stornext does play well with their LSI-disk products; Oracle, I don't see it. I guess Apple could go nuts and buy them; remember they probably ship more Stornext than anyone.
It could end-up as an IP fire-sale at some point...It's a hard place to be.
But no you can't see them...it's commercially sensitive information. :-(
You'll have to trust me; I have no vendor affiliation; suffice to say, it is not quite as simple as taking the cost of an LTO tape, you have to factor in SAN, Robot, Tape library costs; both capital and operational expenditure.
With The Register's antipathy towards Apple and the iPhone; and now displaying antipathy towards Google and Android; we are now in the bizarre situation where they are grudgingly praising Microsoft.
What a bizarre world we live in!!
