ZFS mix disks diffrent size and speed in a pool

[Jean-Marc LACROIX]

Hello,

     we actually have a storage solution based on a DELL 630 + 3 JBODs 
DELL MD 1420 (HBA mode),

The ZFS pool is made of 9 raidz2 vdevs + 1 mirror log + 2 spares

     All disks are of the same type in capacity and speed.

The problem is that DELL is unable to provide the SAME kind of disk 
(capacity AND speed)

when a disk has to be replaced. So the question is:

Is it possible to replace a 1TB 7200rpm by a 1.2TB 10000rpm disk without 
any consequences for the existing pool ?

THanks in advance

Best Regards

JM
