STA Selection policy = trigger to change band
5Ghz distance短D
2.4Ghz distance長D
Phy rate = actual link speed
2.4G慢 5G快
但係另一方面RSSI 穿牆5G係弱過2.4G
bandwidth utilization個個係點？
唔知係咪過左b/w threshold先activate d rules
Phy rate太多factor同埋跳band有機會更差
N/AC就一定架喇，只係佢係咪會auto detect current state然後remap d client
我琴日同老細過左澳門
老細話叫我自己走先，佢去買d野
原來Linksys套Velop Mesh真係可以拆開賣
求先諗到條橋用GCP開Windows instance然後VPN返屋企連SMB最後用ffmpeg做cloud transcoding
GCP裝Win2012 trial
開個VPN返屋企
ffmpeg on SMB share
我發現Ubuntu個wifi hotspot都係將張Wifi card放入AP mode然後靠iptables masquerade
你payme個名叫chu*******果個就可以直接過數
唔好同我爭 我要放落部 Dell PowerEdge 到
triband仲難搞，好易會drop connection
而家我AC all push to 5
not really expensive, around $3000
you dont know the power of rtx
話 RTX 2060 勁過 GTX 1070 Ti
GPU/PCIe access over network
依家 network 越來越快，乜野都可以 converge 落去
Reason? Except for being $$$
- Stable
- SR-IOV Support
- Lots of configuration
- Better performance at lower packet sizes
雖然都有啲伏味不過 performance 都係好過 Realtek
Receive Side Scaling 可以將收番黎嘅 packet 平均打散比你個多核 CPU 收
@licson how to move rootfs to mdraid raid5 without recreating a new array setting
one of my drive is used as boot medium...and i had 2.5T wasted
i know i could migrate it to usb but it was never a good thing
i used whole disk raid member...
googling only tells me about raid1 grub install...
really nobody use raid5 nowadays
raid 5 is not recommended for business use
Dell已經唔recommend client 用Raid 5
rebuild speed, redundancy
2009, dude, it's almost a decade
not fault tolerant...and it is my media center
please read thru the article
it is lucky that my deployments are now dockerized...
