XIV really doesn't compete with anyone at the moment does it? I mean it taps out at under 200 disks. Unless your talking about some sort of XIV+SVC combination.
I've drilled 3PAR over the past 3 years as to why not support more usable capacity, their response is there isn't a market demand for it, the average 3PAR system in the field has about 400TB of raw (or usable I forget, I assume raw) capacity on it. I guess people don't load up their arrays. When I got my T400 back in 2008 I immediately had the first two nodes maxed out for capacity(150TB raw - but not maxed out for I/O), so was always curious why they didn't push capacity further. I guess if the customers aren't pushing for it then there isn't a need to develop it.
As to EMC - don't you find it curious that they haven't gone beyond 8 engines at this point? I mean going back to when they introduced it they were saying how they were going to have many more engines. But for some reason even on this new big 40k they stuck with 8? I'm certain, especially when loaded up with SSD that a VMAX would need far more than 8 engines to really drive SSD performance, since your easily talking about 10s of millions of IOPS potentially anyways.
3PAR has stated they don't intend to go beyond 8 controllers for the foreseeable future, instead on the V-class they doubled up on the ASICs to about double node performance and massively increased memory capacity.
Certainly feels like EMC went back to the drawing board and reconsidered their original plans for a massively scaled out VMAX.
HDS's SPC-1 performance on the VSP was pretty disappointing (though SPC-2 was very impressive), I wonder if this new 40k VMAX will make EMC confident enough to post numbers on that platform, I'm not holding my breath though.
Question remains do those 8 engines have enough processing capacity to drive the full I/O of the back end spindles ? For VSP it seems the answer is no, at least for random I/O. Wouldn't surprise me at all of VMAX was in the same boat.
Wake me up when EMC gets distributed sub disk raid, with the massive nearline drives coming in the future, traditional whole-disk RAID is going to lose out pretty fast with long rebuild times and higher risk of double/triple/more disk failures.
But I'll give them some credit for at least upgrading the CPUs they were using, bout time. Though I'm not up to speed on the latest Intel code words, it seems Westmere is already 2 years old. Day late, dollar short? Oracle at least is pushing quad socket 10-core Intel procs on their systems. Get with the times EMC.
up late to do a software upgrade on one of my 3par boxes..time to go to sleep.
