尋日有少少問題，對接咗有部機個 send 做唔到 10G
Different colour = different purpose
Purpose of Cat6 cable = to tx/rx to internet
My plan
White = Devices
Blue = IPMI
Orange = Uplinks
Black = Whip somebody's ass
Brown = Rope to bind somebody
啤完用cable tester再stress test下條線囉
但係功能好基本，check 線芯順序，線嘅長度，每條芯嘅長度
Consult Licson's ISP for quotation
Dense Wavelength Division Multiplexing
Coarse Wavelength Division Multiplexing
2 x Cisco OTN DWDM Multiplexers
And at least a pair of fibre connecting the two devices
有冇人可以 provide 個 FTP server，要大harddisk
新手想問下野🙏
有2部機直接用cat5e連線，同subnet，iperf send 9xxMb, 但receive 得6xx MB, mii-tool 兩邊都show 1000 full duplex, 會有咩可能？
A client 連 b server 用reverse mode : 6xx MB
B client 連 a server 普通mode: 6xx Mb
話說 Mellanox 支援好多 Offload……
仲有 UDP offload / VLAN offload / VXLAN Offload / Tunneling Offload
一個係 Ethernet 另一個係 InfiniBand
e1000e + linux 4.14 = ???
然後 Multimode Transceiver 用到 Single Mode 光纖
我隻 MM 光纖係買黎插 Switch 所以唔啱兩部機互插
Hong Kong Broadband Network
通常有錢仔用 PCCW / Business BB
Fixed network FUP ho chi is
modem<-mtu1500->server/router<-jumbo->pc
if external use jumbo frame
will cause problem downloading files from aws s3
Update Firmware再 Troubleshoot
Unless you have a seperate internal network where all guys understand jumbo frames
@licson have you tried gpu on windows container
用windows container裝visual studio🤔
我想咁試 不過用緊windows 10所以冇得用native windows container 要轉hyperv
!!! i try iperf with UDP , up/down all 1G
用緊onboard gigabit ethernet port, 其實係由邊度offload左去邊度...?
My network's running ~500Mbps now
trying to get it back to normal
不過係bash on windows可以行docker已經好好😔
windows有個monolitic driver去map linux kernel call但係好似唔支持asynchronous call
