Hello all,

I am about to start a FAST configuration for a customer that will only include FC and SATA disks.  I have read the EMC Clariion FAST document but it doesnt answer a few questions i have.

From what i read, i should create storage pools that i need and then i will add them to FAST.

The customer has the following disks to work with

40 300G 15K FC

15 146G 15K FC

7 2TB SATA

My plan was to create multiple 4+1 R5 groups with the 300G FC disks.  I read that the 4+1 was the optimal pool config to use in storage pools.

I was then going to use (14) 146G FC drives and create a R1/0 pool.

For the SATA disk, i am really limited since i need one for a HS and 6 disks is not realy optimal for a R5 pool.  I can make a 6 disk R6 pool but just not sure.  If i dont make the R6 pool, then i have a  disk just sitting there...

I am hoping that with this config, i will have 3 tiers of storage R1/0 FC, R5 FC, R5 SATA (since i cant have EFD, FC, SATA) and that FAST will know to move something up to the R10 pool if it needs to from the R5 pool.

First question is, once i create this pool, if later down the road the customer purchases EFD and wants to add it to the FAST config, can it be added without wiping everything off the current FAST pool?

I think i am missing something since i dont understand how to make those multiple 4+1 R5 groups into one big group?  Unless it is that i need to create a pool, right click it and select Expand, and then add the other pools?   I thought you can only do that with disks?  This will be my first time configuring FAST so i guess i will have to wait till i can see it in front of me.

Any advice will be great

Thanks
