apritzel: btw, now sunxi-fel works great with H616, no more fiddling with separate commands

20:43 <apritzel> ullbeking: Allwinner SoCs are not a good choice for two GBit ports
<ullbeking>
20:44 <apritzel> ullbeking: some have one GBit + 100 Mbit, but for two Gbit you would need an H6 SoC, which has USB 3.0, and attach an USB GBit adapter
<ullbeking>
yes, it seems so. i think that implementing what i want from cheap sbc's or similar things, it would have to all end up a bit "dongly" if you know what i mean. i think for 2x proper NIC's, plus 2+ on-board SATA controllers, plus (ideally) ability to plug peripherals directly to pci-e, i would need a proper mini-itx mainboard.

ullbeking: yeah, by design all those SBCs use smartphone/tablet/set-top-box SoCs, which are by their very nature not very good at I/O
<ullbeking>
apritzel: so what ARE they optimized for?
<smaeul>
wanting multiple gigabit ethernet + multiple sata puts you in the helios64/macchiatobin/developerboard/ten64/honeycomb market segment
<apritzel>
they are cheap, don't cost much and are not expensive ;-)
<jernej>
at least some of them are great for multimedia center :)
<apritzel>
the Espressobin is probably the cheapest in this crowd
<ullbeking>
smaeul: apritzel: i think you're absolutely right
<smaeul>
yes, video playback (TV box, kiosk, car display) seems to be what they are optimized for
<apritzel>
ullbeking: the eBin has three Gbit and a SATA
<ullbeking>
i actually have a pile of corebootable mini-ITX boards that might be suitable, not sure however (D510MO, D945GLCF, etc). never seriously looked at Ebin/Mbin, etc.
<ullbeking>
the idea is to build a cluster implemented as a "stack" of boards separated by 2" standoffs
<ullbeking>
and to run Ceph on it
<ullbeking>
21:48 <smaeul> wanting multiple gigabit ethernet + multiple sata puts you in the helios64/macchiatobin/developerboard/ten64/honeycomb market segment
<ullbeking>
thanks for the suggestions. i've been out of the loop for a while so some of these are new to me.
<smaeul>
the downside of all of those boards (other than helios64, which is rk3399) is that they require some blob
<apritzel>
ullbeking: but in general any 100 €/£/$ PC mainboard beats a bunch of those when it comes to I/O performance and number of connectors
<ullbeking>
apritzel: ebin is suited for networking appliance whereas mbin is for a storage appliance?
<ullbeking>
apritzel: +++++
<apritzel>
ullbeking: both eBin and mBin are networking chips
<ullbeking>
apritzel: an atom-based soc with proper nics and io interfaces is going to be ideal, and can be had at not much more cost
<apritzel>
I think those SBCs shine when it comes to price, size and power consumption, but only if you don't expect too much
<apritzel>
and heavy I/O is certainly out of their comfort zone
<smaeul>
IIRC, synquacer developerboard may not require a blob, but it has most of its I/O behind a PCIe x1 link and switch, which is why I ignored it when it was new
<ullbeking>
apritzel: oh don't get me wrong. i LOVE them. the OPi +2E is one of my all-time favorites, and I have a 5-node cluster of OPi +2E.

I am not convinced that a cluster of SBCs is really a good idea, since you lose many advantages, but don't gain enough
<ullbeking>
apritzel: it's just a silly experiment

where would you place the point at which the value is worth the effort, apritzel ?
