  1. interesting. what was your application that needed so much bins?
  2. It looks like we have PCIe 2.0 which supports 500/500MB simultaneous read/write bandwidth. There are some cheap Asus 10Gbe adapters that could possible use all the bandwidth available (read from SATA, write to PCIe and in the opposite direction), so we can see close to 400/400 out of 10Gbe port without RAID overhead. I'm not interested in RAID, just a JBOD performance Edit: Not sure about the exact wiring in Espressobin and capabilities of shared SERDES lanes among PCIe2.0 and SATA, some research says around 7.5Gbps total throughput, so I'll lower expectations to 3Gbe full duplex
  3. not a bad idea By looking at http://espressobin.net/wp-content/uploads/2017/01/ESPRESSObin-V3-Hardware-Block-diagram-v3-1.pdf , one could imagine that we might get much higher than 2Gbps if we go 10Gbps PCI-E adapter route.. SATA has it's own direct lane to SoC..
  4. unfortunately you are right, Topaz is connected to SoC via RGMII (1Gbps) so no chance for port channel.
  5. @Igor do you have a procedure for non-internal staff that would get v7 on the official support list? Maybe some of the guys could do the tests if what @ManoftheSea said is not enough. Thanks
  6. Here is the configuration of Cisco switch side: interface Port-channel2 description LACP Channel for mk2 switchport trunk encapsulation dot1q switchport trunk allowed vlan 1,2 switchport mode trunk spanning-tree portfast trunk ! interface GigabitEthernet1/0/23 description mk2 eth0 switchport trunk encapsulation dot1q switchport mode trunk channel-group 2 mode active ! interface GigabitEthernet1/0/24 description mk2 eth1 switchport trunk encapsulation dot1q switchport mode trunk channel-group 2 mode active ! armbian module config: # /etc/modules
  7. Hi everyone, especially armbian maintainers! I'd like to make use of great performance of this board regarding SATA performance which is crippled by 1Gbps so my question is, would etherchannel work on this hardware? I understand that the board has only 1Gbps from the switch (dual LAN ports) so I guess the only possible way to exceed 1Gbps output would be to bundle WAN && [LAN01|LAN02]. Anyone tried this or believe it should work? I don't have the board to try. Thanks.
