I have been looking into Rockstor for a while now and finally decided to do a newish build, some old parts some new, and give it a go and figured I would post how it is going. The only new parts to the build are the system board and processor, memory and 10Gb NIC is from another server I was no longer using, the 3Tb drives drives are from my old FreeNAS box.
Supermicro Micro ATX X11SSL-CF system board
Intel Xeon Processor E3-1275 v5 processor
16 Gb of Samsung DDR4 2133Mhz ECC
HP 10Gb NIC
Rockstor is currently installed on an old 160Gb laptop drive just to get it up and running and try it out, its running off the onboard SATA controller. Will move to a small SSD down the road.
My data is residing on 4 x 3Tb Hitachi 7200 RPM SATA drives configured as a 5.4TB Raid 1 Pool running off the LSI-3008 SAS controller on the system board.
I am currently copying my data off my Windows server, transferring at between 3 and 3.5 Gbps on large files, its coming off a nVME SSD in the Windows server.
I will probably add a few SSDs in a separate pool for faster storage and use the Hitachi’s for backups.
My one question is will Rockstor always cache all of the the available memory like this and if so, is 16Gb enough memory for this configuration.
