background is:
I have a cse-826 left over (cheap 847 came in the way) i would like to use as a zfs storage box now.
Intended usage is vm-backups, bits of NFS and also to have a place to get some vm's temporary off my proxmox-nodes when doing some potential dangerous things while working on storage-plugins.
Sharing will be done by a mix of iscsi, srp and maybe iser via scst and also nfs. Network should be 1GBe and i'll need to put a Dual-Port cx2 with 1x qsfp + 1x sfp+ in there for connectivity to the proxmox san.
Goal would be as low as possible idle power with a reasonable investement for board, CPU and RAM.
in terms of Backplanes i have an A, a SAS2 Expander and also a SAS3 - Expander in the repositiory. currently sas2 Expander is mounted. (sas3 will most likely go into the back of the 847, has sas3 in front with 3008 and sas2 back on onboard 2108)
thinking quite some time now about the options, i finally came over the x10sl7-f with 2308 onboard + 1x pcie3 x8 for the mellanox and a spare pcie2 x4 what should be ok for a while. (and keep me from going 2011-3 and ddr4) .
the question is now, can the 8x SAS ports be hooked to the sas2 expander backplane with 2x fan-in cables (4x SATA/SAS -> sff 8087 + sgpio from the board) ?
If this Works, for my understanding it might also be possible to daisy-chain from the backplane via sff 8088 on bracket to an external JBOD in the future? 2308 should be ok for quite some drives, and it apears the chip is on internal x8, too.
any ideas/experiences?
also, other ideas how to turn the chassis into a zfs-based storage box that fits the above needs are really welcome.
