It was my understanding that the ZCS disks were actually 520 block-per-sector disks rather than 512 blocks-per-sector and that the checksum was stored in the "extra" 8 blocks. This would essentially make it the same size as a 512 block disk with the same number of blocks, right? Maybe those disks are just smaller anyhow?

Hi All
We have 9 x F760 Netapp Filers, 4 in Cluster Mode and the 9th one is what we have reserved for Snapmirror.
We currently snapmirror volumes from these 8 filers to the backup filer. However, All existing filers have the old FC9 Disk Shelves with 36 gig disks in, and the new F760 Backup Filer has the new DC14 Disk Shelves with 72 gig drives.
What should have been a disk for disk snapmirror configuration, either by having 36 gig to 36 gig or 36 gig x 2 to 72 gig disk, has become more complicated as the new disks have a different Zone. The new zone makes the new 72 gig disks slightly smaller than 2 x old 36 gig disks.
I was wondering if anyone else might have encountered this problem yet, and if there is any workarounds as to disk zoneing, etc etc.
Thanks KEVIN
