3 Dell Equallogic PS6010's

Hello,

I have 3 Dell Equallogic PS6010 Raid 6 Accelerated what is the optimal configuration for performance and reliability. Should i put all the members in the same pool with a few volumes?? using this configuration what if one of the members die in the pool will the volumes still be online?? Or should I have a separate pool for each member and syncrep accross?

Thanks!
