Hey folks, Running a 3 node HCI cluster (in testing stages) I would love to hear your input. All nodes are exactly identical and have a local storage of 8tb in SSDs made out of a RAID6. Gluster was setup to match this (Raid6, cluster of 256k). There is the option of compression & dedup, coming from ZFS this is a memory hog and kind of insane. What are your thoughts on compression & dedup at this time? The effective size of the compressed drive is suggested 10-fold of the original sizes. Seems a big crazy high; any suggestions here?

is ovirt using VDO for dedup and compression? https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrast... best regards, markus
