Yes, multiple levels of striping is not a good idea on traditionally provisioned volumes. This is because on thick volumes you want to keep LBA addresses close to one another on the disk to reduce seeks.  Since VP is already wide striped over all the disk, the additional striping doesn't really impact the performance the same way it would on a thick LUN.  The difference in performance from multiple Symm volumes active vs. 1 can be significant, which is why we recommend striped VP metas for performance.
Hello community [IMAGE],  I've been involved with VMAX since a few weeks now and I was wondering whether or not creating striped metas in a pool is good for performance or whether or not it's better to create concattenated metas?  In my DMX days I've learned that 3-way striping always should be avoided: 1) RAID5(3+1); 2) striped META; 3) host based striping. 2 Out of 3 is ok, but all 3 is not. So in the environment I'm working in right now I'm seeing all 3 implemented and I was wondering is this is ok. I'm reading through "Best Practices for Fast, Simple Capacity Allocation with EMC® Symmetrix® Virtual Provisioning™ Technical Notes P/N 300-006-718 REV A13 June 8, 2011", but I'm not sure what it says. What's your professional oppinion about this ?
