The Shark (2105-800) can be setup with the Array's Across Loops (AAL) feature. This is something you want to mention to your CE or the specialist helping you provision the storage processor. This is disruptive to customer data so you won't want to find out that you did not provision the array's this way after you have populated it.
There are some excellent Redbooks on FICON and 2105 for example: IBM TotalStorage Enterprise Storage Server Model 800 Performance Monitoring and Tuning Guide http://www.redbooks.ibm.com/abstracts/sg246422.html?Open http://www.redbooks.ibm.com I would suggest you may want to decide how you want the new storage processor configured and if 3390-9 sized volumes with more PAVs are where you want to go then consider to use FDRPAS to migrate 1 3390-3 to a 3390-9 and then get the required outages to migrate additional volumes rather than just using FDRPAS to go -3 to -3 for everything. It will take longer but if you don't start moving to larger sized volumes now you may find it more difficult later. Just something to consider. The initial implementation of shark DASD with PAV here took over 3 hours off the nightly batch cycle. You may want to look at the hardware RESERVEs that you are still allowing to go unconverted if any very carefully as you move to larger volumes.

No one here has experience with this. A DBA asked the following questions: What are the performance differences between volumes defined as MOD-3, MOD-9, MOD-27? What are the implications of changing a volume to a PAV volume? What type datasets/databases, if any, are required to be on their own volumes? I just need some generalities.
