Yes, that's my understanding. It's the only way I've known R1/0 to be constructed.  Also, I recall a procedure referred to when I've created RAID 1/0 Groups in the past which showed the correct way to select the disks in order to determine the Primary & Secondary disks in each 'span'. ( There was no tertiary etc).
Hello,   I have some questions regarding RAID 10 and how does it work. your help is really appreciated   - The expression "RAID 1/0" does it mean RAID 10 or it may refer to another RAID level like RAID 1 ?  - The minimum number of disks for RAID 1 ? ( Two disks, please confirm) - The minimum number of disks for RAID 1/0 ? ( Four disks, please confirm) - Can i create a storage pool only contains 2 disks with RAID 1/0 when we use the Unisphere to create new storage pool? -  RAID 1/0 has a preference of 4+4 disk but how data will distributed ove 8 disks , is it like the same distribution over 6 disks with additional RAID 1 set.
