如果想set隻家用Router，識下面呢堆野就好似夠用
- Set interface IP, gateway
- Default Gateway to ISP
- DHCP Server
- PAT
btw 有無人知BCM5703c明明1Gbps但得100Mbps
我記得以前見過1000Mbps full duplex
access only
intel裝埋driver可以set trunk
一條線trunk入個nic之後再virtual nic出返個adapter出黎
入vlan id就爆多個virtual nic出黎
dot1q可唔可以同isl trunking傾計?
我發覺一樣野：只要配岩個scenario，其實cisco都幾多野係開罐頭既
我公司果度已經nobody fucking cares
雖然 Prod 個套都係 7604 分 10G 出嚟落部 3750E
不過我遲啲可能會換 10G，因為打算換過個 Virtualization 系統，跟住會用 Ceph
我係度諗，router on a dick再加PAT係咪一樣咁set
其實就係將啲 Server 嘅 Storage consolidate 埋一齊
Ceph 會自己做 Replication 同埋 scale up/down
跟住就係買 N5K 嚟做 storage 部分嘅 switching
其實 Ceph 行乜嘢網都得嘅，不過 Eth 係最簡單……
我都唔知有咗 FC Switch / FC Controller / FC HBA 之後要點樣 assign 啲 storage 落啲 VM 到……
Ceph 嘅話我可以用返 Server 嘅 Local Storage
Consolidate 咗 storage 個部分
然後可以 instruct VM 去用佢個 Block Storage
佢係 Linux 都係就咁 Block Device
可以叫 KVM 直接食咗個 Block Device 嚟開機
14nm+ = Skylake
14nm++ = Kabylake
14nm+++ = Kabylake Refresh
14nm++++ = Coffee Lake
14nm+++++ = Cascade Lake
So 14nm++++++ = Comet Lake
I bet there'll be 14nm+{10} which means 10x improvements on the 14nm process
14nm+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Maybe 10x the vertical composition
(log(10)
/log(2))x improvement
So the same 14nm wafer can hold 10x transisters
