Hello to all, got a theoretical question while trying to understand what to do to help my Freenas respond better.
Got a hot storage with mirrored SSDs (x6) (Sata III). Those are being backed up to a cold storage of regular hdds.
The hot storage at times during the day is accessed simultaneously by 6+ nodes , all attacking the same file ( that can range from 500MB to 2GB size). All that is happening over Gigabit lan connections, via a switch with 48Gbps bandwidth, which to my understanding is enough to serve on full Gigabit rate each node.
Upgrading to 10Gbe network , is on the to-do list of next week.
My question is, when resolving the 10Gbe switch upgrade, the theoretical transfer speed that we will get per node will it be something like
(zpool read speed)/(number of nodes)
when accessing the directory?
Or is there any more sophisticated way that the system responds to simultaneous data reads?
Please forgive my crude , non-poetic attempt to quantify the issue. Any ideas will be appreciated :)
