James, >Geez ... it's only an example <g> I realize that, but part of the point was one needs to do the math in each particular case. As I said, I wasn't necessarily knocking the theory, if there were enough drive arms left and if there was enough data moved to the historical data ASP. >Actually, the drive counts were from the original post as a point of >reference, the percentage of usage was from my own experience. OK, that explains where you got the 40%. <g> >In the real case, we doubled our total disk capacity (but not arms, due >to drive difference) and dropped from pushing 70% to 35% utilization in >the base ASP. That would be much different than reducing the base ASP under 10%. >Maybe what I'm getting to is that it's more than just the hardware >numbers that determine if one should or should not have a separate ASP, >but the user community and/or data base structure and demand that makes >this kind of request an "it depends". Moving fully half the data out of the ASP when it is used by < 5% of the people at a time does change the perspective. As drives have become larger, it seems people tend to forget about arm count and only consider storage capacity. I think you need to consider both. >BTW, I won't tease you too much for stating drive capacity in MB instead >of GB, it's these types of easy mistakes that can cause someone to get >picky with your post. <G> Oops. I guess it was too late to catch that. At least the math ratios turned out the same. <g> >P.S. I've seen a lot of email shorthand, but never YMMV. I'm guessing: >Your Move M... V...? Or maybe: You Make Me Vomit? I hope you're >playing nice. Your Mileage May Vary. Meant as a reminder that these things have to be considered on a case by case basis. I wasn't trying to flame you.
