Sizing Guide for VMware Horizon Servers and Access Points

[fa icon="pencil'] Posted by Johnny Ma [fa icon="calendar'] June 21, 2017 [fa icon="tags'] VMware, How To Guide, PowerShell, VMware vSphere, VMware Horizon

Often times I’m called in to perform a health check of a VMware Horizon environment due to a performance or operational issue. These issues make the environment unstable and effect user productivity. There are various things we can do in the environment to optimize the persistent or non-persistent virtual desktops, but first we need to make sure the virtual desktop infrastructure is configured properly.

Proper configuration entails proper server sizing. More often than not, these servers are not sized properly. Under-sizing causes performance issues and over-sizing wastes resources.

How to Deploy VMware Horizon Access Point via PowerShell

[fa icon="pencil'] Posted by Johnny Ma [fa icon="calendar'] May 24, 2017 [fa icon="tags'] VMware, How To Guide, PowerShell, VMware vSphere

The VMware Horizon Access Point greatly reduces the amount of resources needed for the redundant or non-redundant Horizon Environment.

Previously when deploying Security Server, a single Security Server needed to be sized as a Connection Server which is 4vCPU and 12GB of RAM. If you combine that with the Connection Server that the Security Server is paired with, the Connection Server is once again 4vCPU and 12GB of RAM. If this was a redundant environment your Connection Server and Security Server infrastructure tallies up to 24vCPU and 72Gb of RAM (2 Internal Connection Servers, 2 External Connection Servers and 2 Security Servers all sized at 4vCPU and 12GB of RAM).

How to Score an A Grade on Your Citrix NetScaler SSL Virtual Servers

[fa icon="pencil'] Posted by Johnny Ma [fa icon="calendar'] February 14, 2017 [fa icon="tags'] Virtualization, Citrix, Citrix XenApp, Citrix XenDesktop, NetScaler

Have you had your external SSL based Virtual Servers on a Citrix NetScaler scanned? Scanning with free utilities such as ssllabs.com can ensure that you have the proper certificate chain on the NetScaler to avoid any certificate errors on browsers. In addition, this can flag any security issues with your SSL based virtual servers.

But what if you don’t get an “A”? Let’s look at what causes a lower letter grade, and what you can do to improve your score.

How to Fix Applications Not Working with Citrix MCS or PVS

[fa icon="pencil'] Posted by Johnny Ma [fa icon="calendar'] December 6, 2016 [fa icon="tags'] Virtualization, Citrix, Microsoft, Managed Infrastructure & Helpdesk

I always encourage clients to use the single image management solutions provided by Citrix. When done correctly, Machine Creation Services (MCS) and Provisioning Services (PVS) deployments can significantly decrease administrative overhead of managing images.

Updating the gold/master image and deploying read-only copies ensures not only consistency and ease of use in the environment, but makes the environment user-proof. Unfortunately, sometimes when clients implement MCS or PVS, it doesn’t play well with their current applications. These hurdles can make a client want to abandon single image management, but we can utilize tools that are already built into the Active Directory environment to resolve these issues. Here's how.

NetScaler Website Redirection - The Nice & Elegant Way

[fa icon="pencil'] Posted by Johnny Ma [fa icon="calendar'] August 10, 2016 [fa icon="tags'] Citrix, Citrix XenApp, Citrix XenDesktop, How To Guide, NetScaler

Did you know that you can configure NetScaler so users don’t have to type in the https:// when going to StoreFront or the NetScaler Gateway URLs?

More often than not, this is accomplished using a crude method in which port 80 http Virtual Server is configured on the same IP as the https site and the Redirect URL field in the protection section of the Virtual Server is set. While this works just fine, it unfortunately also renders a permanently Down Virtual Server in the Load Balancing screen.

Good news though, there is a better way to configure the redirection that renders all of the Virtual Servers as Up by using Responder Policies.
