3: 5:This weeks main focus has to do with VLANs. Before reading the material when i heard the term VLAN, i wasn’t sure how a vlan would a corporate environment. i always though “why not just create another subnet and be done with it”, after reading and doing some research i discovered that setting up vlan actually networking much easier, because the traffic can be routed according to the environment. our reading material provides an example how someone from accounting can work at the shop floor and be on a separate vlan a shop supervisor. how is beneficial? well for one it s to route traffic properly and eliminating congestions. second, a network administrator doesn’t have to deploy additional switches for different devices. for example, on a 24 port layer 3 switch 12 ports can be used for one vlan and the other 12 can be used for a different vlan. tagging ports on switches will tag the traffic with that vlan, additionally, you can configure a NIC’s setting with a specific vlan so the traffic gets tagged at the host not the switch. vlans save time and makes managing a network much simpler. 6: Most companies that i have interacted with are using 1G connections to desktops and for their servers they use 10Gbit connection between the server and the switch. At my employer’s offices we use a 10Gb backbone for our network, this connects our switches to each other and also connects our servers to the switches. the reason we are using 10Gb connections between the servers and the switches is because our servers are running multiple virtual machines, so, we must allow enough bandwidth for all the traffic. we made the mistake of using full 1g everywhere and this created bottlenecks creating high latency that made it painful for the end users. With data only getting bigger, i think that we will start to see 10Gb to desktops and 40Gb backbones as a normal network speeds.
