PVS Write Cache Sizing & Considerations
Every now and then I’m asked where the Provisioning Services Write Cache should be located and how big it might become. So I thought it might be worth to share some thoughts.LocationProvisioning Services supports several options for storing the PVS Write Cache, which contains all disk writes of a target device when using a write-protected vDisk (Standard Image). Options for the write cache location are:Cache ...
Serving several gigabytes of data per second now made easier with NetScaler!
In scenarios where the ISP’s need to cater to several gigabytes of data per second for managing a large chunk of cached data in dedicated SwiftCache Appliances, the NetScaler N-tier cache redirection deployment in conjunction with the SwiftCache Appliance, we help perform Cache Redirection and load balance the SwiftCache Appliances most efficiently.Figure 8a: The Problem (Scenario 1) - The Need of ...
Optimizing PVS
While everyone using Provisioning Services (PVS) in a productive environment should be aware of the basic networking best practices outlined within CTX117374 or the design considerations at CTX125126, there are a couple of advanced configuration options that are not widely known. Today I would like to discuss some of these.Subnet AffinityThe Subnet Affinity feature which has been introduced with PVS5.6, is an advanced load balancing ...

Thank you all for "attending" the web based TechTalk on June 17th, 2010.The topic - "Guaranteeing Availability and Scale for XenApp and XenDesktop Deployments" - covered a lot of ground across a few products. Some questions were raised during the talk.By the way, actual replay of the TechTalk is available here.Let me address some of these:Can GSLB be IP based, without pointing to a ...
NetScaler feature of the day – Deploy as a forward proxy
NetScaler is a full featured Application Delivery Controller providing functions well beyond traditional load balancers. Over the course of ten+ years, we have also accumulated a rich feature set. In this post (series hopefully), I hope to highlight some of the these features.Forward proxy use casesForward proxies are traditionally deployed at the end of the corporate network to provide caching functionality. The most popular proxy ...
Provisioning Services High Availability Considerations – Part 1
I have been working with Provisioning Services (PVS) for a while and one of the questions that keep coming up is around Provisioning Services High Availability (HA).What is HA? Maintaining access to a service or resource is probably the best explanation for this type of functionality.What does HA provide? Within the context of the Provisioning Services resource, we are referring to the target devices ability to ...
Bind Points NetScaler 9 Policies
Policies have a fundamental influence on the behavior of most NetScaler features, (for example, Load Balancing, Content Switching, Rewrite, Responder, Integrated Caching, and the Application Firewall).For a policy to take effect, and to have the desired effect, you must ensure that the policy is invoked at the right point during processing. The binding determines when the policy is evaluated (for example, is the policy applied ...
