from the year of the month when the contact Netscaler, then just have to follow the document configuration, do extranet access to virtual desktop, then still use WI, has not XenDesktop and Netscaler integration, at that time only a document is more practical, the Internet is Netscaler Three kinds of configuration, then the understanding of him is a router-like device, Anyway extranet access needs to purchase Netscaler or use VPX.

Citrix has been pushing its own Netscaler for the last year , but it does have a very good market share, and of course I know Netscaler and XenDesktop Just it's a little bit of a function to do ICA proxy. Recently the company in the construction of the site need to use Netscaler This product, so go to understand this product, a lot of edges and corners of the things are unfamiliar, take advantage of this opportunity to go through the equivalent of consolidating a bit.

First of all, if someone asks NetScaler what is the thing, my explanation it is an OS, of course asked most or netscaler is to do what? I think the first role of F5 as well as A10 as a traditional application delivery controller The basic role of the basic load balancing then there are some security, acceleration, reliability, improved user and mobile user experience.

Netscaler There are three different products, namely MPX (Hardware version), VPX (directly in the supported platform import), SDX (can be easily understood as a xenserver installed a lot of VPX) First review the NetScaler IP address

1) : NSIP This is NetScaler's management address in the MPX version with a direct connection to the Netscaaler management address port, MPX default management address is 192.168.100.1/16, of course you in their local configuration 192.168.100.*/16/ 24 This is all, the two are subsets of the relationship. Then you can use Nsroot and password Nsroot login to the configuration interface, configuration NetScaler, of course nsip in addition to the management configuration, there are two netscaler to do ha when the use of NSIP monitoring, there is to do LDAP authentication and NTP are using NSIP.

2) SNIP is the netscaler above the various services, monitors, load Balancer virtual server and back-end actual application or Web server communication use, each creation of a snip will create a corresponding route, The settings in the actual production environment should be configured for each NetScaler above the service or monitor need to configure their corresponding snip, this can create multiple snip addresses in the network, the previously used MIP is now basically replaced by snip.

3) VIP is the IP address associated with the virtual server. It is the address of the public IP that the client connects to the back-end server. is the direct exposure to the client to access the IP address, that is, often in the firewall or egress routers need to do NAT, such as XenDesktop and NetScaler integration, you need to map the VIP port 443 to the IP of the public network, Public network users can then access virtual desktops and applications using HTTPS encryption. Of course in the build environment when doing lb often create multiple VIP use, the same netscaler also support itself to do NAT functions, Inat and Rnat.

4) Gslbip : This is a global load-balanced site IP address that creates a gslbserver

5) CLIP is the IP address of the cluster, when creating the cluster there will be a clip, after the creation of clip need to use this clip login to netscaler this device made into cluster.
