Upgrade from HDP version 2.6.4 to HDP 3.0 ( dose disks aspect is important for this upgrade? )

we want to know if we can to upgrade to HDP 3.0 from HDP 2.6.4 ( regarding the disks aspect )

and we want to know if current disks configuration enable this upgrade

we have the following RAID configuration

1) Worker-> (OS) Raid1  + ( data disks ) Raid 5 
2) Master -> (OS) Raid1 + ( data disks ) Raid10
3) Kafka-> (OS) Raid1   + ( data disk  ) Raid10

about the kafka - each kafka has one data disk

about the workers ( data-node ) - each worker has 10 data disks

based on that configuration , can we upgrade to HDP 3.0 version ?

Yes you can upgrade HDP from 2.6.4 to 3.0 - you will have to use Ambari 2.7 version.

Don't think RAID configuration would impact the HDP upgrade.
