I would assume this is in response to earlier criticisms of the USP-V design in which the virtualization layer was not redundant(when I learned that I was honestly pretty shocked) – Hitachi later rectified the situation on the USP-V by adding some magic sauce that allowed you to link a pair of them together.

You've lots of different variables but I don't know how they combine. What figure are you trying to calculate? Chris Mpho

Numbero accounts = 5000-100000 Number of ATM's = 256 Number of books store = 500 Number of call centres = 9 Estimated transaction rates = 500/sec I what know if I will need AMS or USP How do I calculate capacity of storage needed if I am given the following.

Numbero accounts = 5000-100000
Number of ATM’s = 256
Number of books store = 500
Number of call centres = 9
Estimated transaction rates = 500/sec

I what know if I will need AMS or USP

However, currently the features are missing: there's no possibility for real tiering, as you cannot migrate data even inside the box from "normal" luns to "thin" luns. And as I've heard, you cannot do lun migrations on thin luns at all. This is seriously flawed and I'm very surprised that there's no attention to this. And when migrating luns, the source is _always_ erased = you cannot use it for repurposing data. Also, the only way to expand luns is by creating meta's and this kind of storage configuration is from the dark middle ages. At some point I'm sure that the V-Max will be usable, but currently there is too little to get excited about, when you are the person who has to really work with it. I'm quite sure that the lacking features are due to the microcode inheritance, which brings too many restrictions originated from the 90's. It is also too bad that HDS has a lot of nice features, but as you stated, the user interface is lacking and of bad design. I wonder when will we get the best of both worlds... -Soikki And BTW, Open replicator means that data is copied offline.
