I am working with our infrastructure engineer to configure out new servers connected to EMC vnx 5300.
We had reserved 18 drives for main data and was planning on using Raid 1+0.
But I am getting from my infrastructure engineer that in RAID 1+0 the number of drives should be divisible by 4 or 8.
Is this correct as I have never heard this requirement before.

The better description is it has to be divisible by 2, but > 2. i.e. 2 drives cannot be RAID 0+1, but 4, 6, 8, 10, etc. can all be done. This is also true of 1+0 or RAID 10. The difference is that one is a mirror of striped sets and the other is a striping of mirrored sets.
Thanks,
