Well, for the most part the constraints are more severe on the midsize product. And actually more particular than that is -- and to put it in perspective, I mean we've introduced products before, but this one actually had 4x the take-up rate of any of our previous products. So clearly, the ramp is pretty steep. And the other thing that's a little bit different about the 3000 family here is they also have this thing called an I/O expansion module, which allows you to put more connectivity in. And the demand for that was much higher than we forecasted as well, and in fact, that ended up being the limiting factor. And probably in retrospect, the lesson learned here is that people were looking to build with the higher performance systems that we introduced, they were looking to build bigger systems. And the other thing is that those slots where the flash cards go in included demand for our flash cards is very, very high. In fact, the attach rate of flash on these class of machines are actually 10 points higher than they were on the previous class. So, overall in terms of constraints, it's primarily in the I/O expansion module, certain semiconductor components along the way. But at the end of the day, demand is really strong, so it's kind of a bright side at the end of this. But nonetheless, it's primarily and then particularly that dimension, I wouldn't call out any individual part, but the simple fact of the matter is we ended up shipping thousands of these units, so we ended up at 4x the demand that we expected. As we go into the next quarter, our guidance currently reflects the fact that we've not resolved these problems yet. We're working on them. We think we have approaches that will resolve them, but it did cause us to take some consideration here with respect to whether or not we get all the parts we want whatever the case. We also can't estimate the mixes correctly. We want to make sure that if there was this huge mix shift, that one way or the other, more modules, for instance, of come on -- OM modules, we can handle that. So the bottom line here is we tended to be a little more conservative with our guidance because we have not solved all of the mix and the material stuff yet.
