This is cool but a shame that they didnt contact Luke for using something
like the a20 or wait for the rk3388 so we could have more money leverage on
the soc and common ICs or even turn this into an eoma housing.

https://wikidevi.com/wiki/MediaTek_MT7621

that's a *really* specialist SoC, with USB3, PCIe, 5x GbE and
specialist hardware for optimised throughput on routing tables *and*
hardware-level accelerated crypto.

PCIe could be used to connect NVMe, or, as appears to be the case
here, a PCIe bridge plus SATA.

so it's a great choice of SoC, that doesn't fit into EOMA68 (or
EOMA200 for that matter, as it lacks video output).

The A20 comes with only 1 SATA port (and no other fast port, like PCIe
or USB3) and it somehow saturates at 50MB/s when writing, so it's a poor
choice for a NAS in general (it's usable, but not great). The RK3388
doesn't even have SATA so it's an even worse choice for a NAS.

yehyeh - they're not designed for server-level applications, which is
great... because EOMA68 is not designed for server-level applications
either :)

honestly the router market being so saturated and also
low-cost-focussed (and specialist) i can't really imagine there being
even a *need* for a standards-driven design.

i am however going to be doing an EOMA68 router again: it will be
using the QCA9531. i'll start a new thread about this.

FWIW, I'm using an A20 as a small router+NAS+server and am very
satisfied with it: the limited SATA speed is never the bottleneck since
I connect to it over wifi on one side (where competition with neighbors
and in-house obstacles means I rarely get over 2MB/s) and over DSL on
the other (and here in Canada, DSL speeds haven't changed much over the
last 10 years).

But for a "dedicated" NAS box that can hold up to 6 disks, an A20 would
be a rather odd choice.

its SATA interface is also very very specifically a single LUN.

AFAIK it is compatible with sata multipliers (see discussion at
http://linux-sunxi.org/SATA), tho you have to request it explicitly with
the "enable_pmp=1" module argument.

Ok I stand corrected them. So this basically means we are not going to see
any NAS products from an eoma standard ?

maybe when a USB3 SoC comes out, making the speed worthwhile.

Would EOMA200 be suitable with its pcie and sata interfaces?

not really. EOMA interfaces are mandatory. that means that
everything else - the video, I2C, SPI, SD/MMC and all the other GPIO -
must also be provided.

instead, a case needs to be made for a new standard - and that
includes a thread/narrative as to *why it is justifiable*.

I don't think you can put that large number of drives on a rockchip CPU
