My question is as follows, and I've only been able to find part of the answer. This is related specifically to performance and mixing, for the sake of discussion, 10k fc & 15k fc disks.
Will mixing 10k & 15k rpm disks in an AGGREGATE degrade performance of that aggregate to the 10k rpm disks? **YES** This is the only one I've been able to verify
Documented: http://media.netapp.com/documents/tr-3437.pdf page 15, under "Drive Speed"
Will mixing 10k & 15k rpm disks in a SHELF degrade performance of that SHELF to the 10k rpm disks?
Will mixing 10k & 15k rpm disks in a RAID GROUP degrade performance of that RAID GROUP to the 10k rpm disks?
Will mixing 10k & 15k rpm disks in a FC LOOP degrade performance of that LOOP to the 10k rpm disks?
Thanks for any assistance, or links to relevant documentation
