layer-3 refined QoS features to ensure classification and sorting of network traffic and to avoid congestion in the best way. Before a packet enters the shared buffer, the Catalyst 3550 smart Ethernet switch can classify, reclassify, and process the incoming packet according to the policy (determine whether the packet flow is from the intended user or not, and take action on the package. Packet Classification allows network devices to differentiate traffic and implement policies based on Layer

Jérôme Petazzoni (Docker evangelist) Translator: Mark Shao (senior engineer, EMC China) If you use Docker on CentOS, Rehl, Fedor, or other Linux distributions that do not have AUFS support by default, you may need to use Device Mapper's storage plug-in. By setting this plugin as the default, it will store all your containers in a short 100G file and limit the maximum of 10GB per container. This article will show you how to break this limit and m

However, if the GC takes up to 1-3 seconds or more than 10 seconds, the system needs to be tuned for GC immediately.However, if your application allocates 10GB of memory and cannot reduce memory capacity, there is no way to perform GC tuning. In this case, you fir

However, if the GC's execution time is 1-3 seconds, or more than 10 seconds, the GC will be imperative.However, if you have already allocated

So deploy it as an ESXi host to deploy it.So, of course, you can also deploy a physical machine to do the same thing. But the point here is that we want to save money and save a host, don't we? Then, in order to save money with a special virtual machine to replace the physical host, you have to consider this special virtual machine more.Configuration R

meaning is consistent, such as my machine, the solution is to have a 30GB data disk, through the detection view is currently only used to 10GB, that is, if I now go to install the WDCP Panel Building station, will only use 10GB, and 20GB is not used. We need to launch the 20GB and mount it to the WWW directory installed after WDCP. See the above is also relatively simple, there are 20GB mount in
