Let NetScaler CS vserver perceive lb vs's statusBy default CS vs does not perceive lb vs's State, and regardless of LB's state how CS vs is up. If you want CS vs to change with LB status, you need to enable the "State Update" feature. CS vs also becomes down when all lb of the CS vs binding is all down. This kind of demand should be more common, although netscaler in the design time Enough "self-confidence", think CS

A virtual server represents a cluster of multiple real servers,When a client initiates a connection to a virtual server, it forwards the connection to a real server through a complex balancing algorithm.
There are two load balancing algorithms:Weighted round robin (WRR) and Weighted lea

Some Terminology
Before I show you how traffic flows and what actually happens when a external user connects up to the NetScaler Gateway, I The want to spend a few minutes explaining some of the terminology for need to know and understand we before.
The NetScaler uses Vservers (virtual servers) to deliver different for services, in this case the kinds would be con Figu

I read an article about Virtualization of Linux servers over the weekend. This paper tests the performance of several major open-source virtual products, just in line with the isolation performance of several different virtual technologies that I saw some time ago. The performance and isolation of virtual machines are very important performance indicators of virtual technology. It takes a lot of time and effort to test and compare different products in a large area, this article comprehensively
With F5, A10, deep conviction and other traditional debt-balanced products, NetScaler is generally done based on the application of load balancing, and for the load balance of the link is relatively less than the actual scenario, their own side of the current use of the company developed Web server to do load balancing.Doing load balancing is typically deployed in the following steps (three elements):1) First create server back-end servers (such as the company's OA, ERP);2) then create a service
