Hi Everyone, Any thoughts on this ? On Wed, Apr 3, 2019, 17:02 Leo David <leoalex@gmail.com> wrote:

Hi Everyone, For a hyperconverged setup started with 3 nodes and going up in time up to 12 nodes, I have to choose between LSI2008 ( jbod ) and LSI9265 (raid). Perc h710 ( raid ) might be an option too, but on a different chassis. There will not be many disk installed on each node, so the replication will be replica 3 replicated-distribute volumes across the nodes as: node1/disk1 node2/disk1 node3/disk1 node1/disk2 node2/disk2 node3/disk2 and so on... As i will add nodes to the cluster , I intend expand the volumes using the same rule. What would it be a better way, to used jbod cards ( no cache ) or raid card and create raid0 arrays ( one for each disk ) and therefore have a bit of raid cache ( 512Mb ) ? Is raid caching a benefit to have it underneath ovirt/gluster as long as I go for "Jbod" installation anyway ? Thank you very much ! -- Best regards, Leo David
