Performance Tuning Citrix Storefront 2.x – #Citrix, #StoreFront via @PeterSmali

February 3, 2014 1 comment

Another great blog post from my colleague Peter Smali!

Performance Tuning Citrix Storefront 2.x

First of all I would like to thank Sandbu who came up with an extra performance tuning trick that I have been testing for a while now.
In this post I’ll be demonstrating an updated version of Sandbu’s due some small changes since the introduction of Citrix Storefront 2.x

As we all are aware of, Citrix Storefront is fully dependent on IIS to work, but it is really suffering of some perfromance issues that surely most of us who have been testing or implementing it are aware of. So Let’s give Storefront a new perfromance birth by doing the following
Attention! Take a backup of all files you are going to modify before doing this! And Remember that Citrix Systems does not support this!!

1. Enable Socket Pooling (pooledSockets=”on”)

Open your C:\inetpub\wwwroot\Citrix\Storename\Webweb.config file as administrator and chenge pooledSockets=”off” to pooledSockets=”on”
By enabling socket pooling, Storefront maintaines a pool of sockets instead of creating a new socket each time a new user connects to Storefront, this will give a better performance for SSL based traffic.

2. Changing the application pool to always running (Windows Server 2008 R2)

If you are running Storefront on Windows Server 2012, there is already a new feature implemented in IIS called always running on the application pools but if you are still Windows Server 2008 R2 as I do then you need to do some manual changes…

But if you are still running Windows Server 2008, then you need to do the following:

2.1 Download and install Application Initialization Module for IIS 7.5. A reboot may be required to finish the installation process…

2.2 Open the C:\Windows\System32\inetsrv\config\applicationHost.config on the storefront server as administrator and locate the following setting <configuration><system.applicationHost><applicationPools> and add thealways running paramter startMode=”AlwaysRunning” on each of following application pools

•Citrix Delivery Services Authentication
•Citrix Delivery Services Resources
•Citrix Receiver for Web
•Citrix Delivery Services

The result may look like this:

add name=”Citrix Delivery Services Authentication” autoStart=”true” managedRuntimeVersion=”v2.0″ managedPipelineMode=”Integrated” startMode=”AlwaysRunning”>

2.3 Now locate <configuration>…

Finetuning a Citrix StoreFront deployment

And also ensure that you intelligently load balance your XML brokers, my suggestion is to use content switching in combination with load balancing to get a more optimal solution in place.

Ensure that you DON’T use FQDN’s when you add the XML broker name into the Delivery Controllers config of the StoreFront Store!! Use NetBIOS names, and NOT like farm1.company.com, rather specify “farm1″ and then ensure that the StoreFront server can resolve “farm1″ to your CS VIP, that will speed enumeration up a lot due to that StoreFront first checks via NetBIOS/WINS which isn’t that optimal!

Content Switching instead of Load balancing of XenApp XML brokers? – #XenApp #NetScaler #CS #LB

Happy StoreFront’ing!

Google + Microsoft = Process Explorer 16.0 – #Google, #VirusTotal – via @lseltzer

February 3, 2014 Leave a comment

This is kind of cool!

The latest version of Process Explorer, one of the top tools in Microsoft’s popular Windows Sysinternals suite, has incorporated support for the popular VirusTotal service run by Google.

The Sysinternals tools were written by Mark Russinovich and Bryce Cogswell before Microsoft bought their company many years ago. Russinovich continues to develop the tools in his spare time at Microsoft while working on their Azure cloud service.

To quote the “What’s New” section on microsoft.com:

    Thanks to collaboration with the team at VirusTotal, this Process Explorer update introduces integration with VirusTotal.com, an online antivirus analysis service. When enabled, Process Explorer sends the hashes of images and files shown in the process and DLL views to VirusTotal and if they have been previously scanned, reports how many antivirus engines identified them as possibly malicious. Hyperlinked results take you to VirusTotal.com report pages and you can even submit files for scanning.
Check.VirusTotal.Menu

VirusTotal was created and built up by Hispasec Systems, a Spanish security consulting firm. Over the years it became wildly popular to the point where it needed a cloud infrastructure on the scale that a company like Google could provide. Google took the service over in 2012 [Corrected from 2007].

If you haven’t seen this then have a look at what 2.2 now has to offer!

  • StorageZones for ShareFile Data — You can store ShareFile data in either Windows Azure cloud storage or a private single-tenant storage system that you maintain. You specify a storage option when you configure StorageZones for ShareFile Data. 
    Diagram of on-premises data storage

What’s new

StorageZones Controller 2.2 provides the following enhancements:

Support for Windows Azure storage containers — If you have a Windows Azure account, you can use an Azure storage container for your private data storage instead of a locally-maintained share.

To get started create a new zone and choose the Azure option when you configure StorageZones for ShareFile Data.

Click here to learn more

Connectors to SharePoint root-level sites — You can now create a StorageZones Connector for a SharePoint root-level site or site collection, enabling users to navigate all of the subsites and document libraries in the site. To provide more limited access, you can continue to create connectors to individual SharePoint document libraries.

Click here to learn more

Connectors to user home drives based on Active Directory — You can now create a Connector for network file shares that reliably points to user home drives. To create a connector for user home drives, set the UNC path to the variable %homedrive%. StorageZones Controller will then create connectors based on the user home folder path property in Active Directory.

Installation on non-English operating systems — You can install the English version of StorageZones Controller on the following operating system versions: French, German, Japanese, Simplified Chinese, and Spanish.

#Amazon WorkSpaces – “#VDI” cloud service – #VDI, #BYOD

November 15, 2013 Leave a comment

This is an interesting offering from Amazon! I however don’t like that everyone talks about the “VDI” concept all the time.. this is based on Windows server with Desktop Experience and not a client OS.

Amazon WorkSpaces is a fully managed desktop computing service in the cloud. Amazon WorkSpaces allows customers to easily provision cloud-based desktops that allow end-users to access the documents, applications and resources they need with the device of their choice, including laptops, iPad, Kindle Fire, or Android tablets. With a few clicks in the AWS Management Console, customers can provision a high-quality desktop experience for any number of users at a cost that is highly competitive with traditional desktops and half the cost of most virtual desktop infrastructure (VDI) solutions.

WorkSpace Bundles

Amazon WorkSpaces offers a choice of service bundles providing different hardware and software options to meet your needs. You can choose from the Standard or Performance family of bundles that offer different CPU, memory, and storage resources, based on the requirements of your users. If you would like to launch WorkSpaces with more software already pre-installed (e.g., Microsoft Office, Trend Micro Anti-Virus, etc.), you should choose the Standard Plus or Performance Plus options. If you don’t need the applications offered in those bundles or you would like to use software licenses for some of the applications in the Standard Plus or Performance Plus options that you’ve already paid for, we recommend the Standard or Performance bundles. Whichever option you choose, you can always add your own software whenever you like.

WorkSpaces Bundle Hardware Resources Applications Monthly Price
Standard 1 vCPU, 3.75 GiB Memory, 50 GB User Storage Utilities (Adobe Reader, Internet Explorer 9, Firefox, 7-Zip, Adobe Flash, JRE) $35
Standard Plus 1 vCPU, 3.75 GiB Memory, 50 GB User Storage Microsoft Office Professional 2010, Trend Micro Anti-Virus, Utilities (Adobe Reader, Internet Explorer 9, Firefox, 7-Zip, Adobe Flash, JRE) $50
Performance 2 vCPU, 7.5 GiB Memory, 100 GB User Storage Utilities (Adobe Reader, Internet Explorer 9, Firefox, 7-Zip, Adobe Flash, JRE) $60
Performance Plus 2 vCPU, 7.5 GiB Memory, 100 GB User Storage Microsoft Office Professional 2010, Trend Micro Anti-Virus, Utilities (Adobe Reader, Internet Explorer 9, Firefox, 7-Zip, Adobe Flash, JRE) $75

All WorkSpaces Bundles provide the Windows 7 Experience to users (provided by Windows Server 2008 R2). Microsoft Office 2010 Professional includes Microsoft Excel 2010, Microsoft OneNote 2010, Microsoft PowerPoint 2010, Microsoft Word 2010, Microsoft Outlook 2010, Microsoft Publisher 2010 and Microsoft Access 2010.

#Windows server 2012 Storage Spaces – using PowerShell – via LazyWinAdmin

November 12, 2013 Leave a comment

Very good work on this blog post about Windows Storage Spaces!

WS2012 Storage – Creating a Storage Pool and a Storage Space (aka Virtual Disk) using PowerShell

 

In my previous posts I talked about how to use NFS and iSCSI technologies hosted on Windows Server 2012 and how to deploy those to my Home Lab ESXi servers.

One point I did not covered was: How to do the Initial setup with the physical disk, Storage pooling and the creating the Virtual Disk(s) ?

The cost to acquire and manage highly available and reliable storage can represent a significant part of the IT budget. Windows Server 2012 addresses this issue by delivering a sophisticated virtualized storage feature called Storage Spaces as part of the WS2012 Storage platform. This provides an alternative option for companies that require advanced storage capabilities at lower price point.

Overview

  • Terminology
  • Storage Virtualization Concept
  • Deployment Model of a Storage Space
  • Quick look at Storage Management under Windows Server 2012Identifying the physical disk(s)
    • Server Manager – Volumes
    • PowerShell – Module Storage
  • Creating the Storage Pool
  • Creating the Virtual Disk
  • Initializing the Virtual Disk
  • Partitioning and Formating

Terminology

Storage Pool: Abstraction of multiple physical disks into a logical construct with specified capacity
Group of physical disks into a container, the so-called storage pool, such that the total capacity collectively presented by those associated physical disks can appear and become manageable as a single and seemingly continuous space.

There are two primary types of pools which are used in conjunction with Storage Spaces, as well as the management API in Windows Server 2012: Primordial Pool and Concrete Pool.

Primordial Pool: The Primordial pool represents all of the disks that Storage Spaces is able to enumerate, regardless of whether they are currently being used for a concrete pool. Physical Disks in the Primordial pool have a property named CanPool equal to “True” when they meet the requirements to create a concrete pool.

 

Concrete Pool: A Concrete pool is a specific collection of Physical Disks that was formed by the user to allow creating Storage Spaces (aka Virtual Disks).

This is great! Have a look at this guide!

Hello everyone, this is Clark Nicholson from the Remote Desktop Virtualization Team. I’m writing today to let you know that we have just published the Windows Azure Desktop Hosting Deployment Guide. This document provides guidance for deploying a basic desktop hosting solution based on the Windows Azure Desktop Hosting Reference Architecture Guide. This document is intended to provide a starting point for implementing a Desktop Hosting service on Windows Azure virtual machines. A production environment will need additional deployment steps to provide advanced features such as high availability, customized desktop experience, RemoteApp collections, etc.

For more information, please see Remote Desktop Services and Windows Azure Infrastructure Services.
