February 19, 2014 1 comment

This is a great PoC guide, some thing I would have done differently in detail but overall great work!

You’ve heard of XenDesktop 7.1, experienced a demo and worked through the Reviewer’s Guide. Now where do you turn when you’re ready for a PoC, pilot and preparations for a full-scale rollout?

Here on the Citrix Readiness and Enablement Team, we’re always looking for ways to empower our customers to be successful on their projects. To this end, we’ve taken one of our most popular hands-on lab guides used to train hundreds of internal and external students and reworked it for consumption by the masses. The XenDesktop 7.1 on Hyper-V Pilot Guide can be download fromhttps://citrix.sharefile.com/d/scaa256260df4ab3b. In this guide we cover the following topics with step-by-step instructions and screenshots:

#Citrix #ShareFile StorageZone Controller logs – #BYOD

January 23, 2014 Leave a comment

This is great blog post by Dan about where to find that little extra info when you’re having issues with StorageZone controllers!

Citrix ShareFile StorageZone Controller logs

When troubleshooting issues with the Citrix ShareFile StorageZone Controller the first place to look will be on the Monitoring page of the StorageZone Controller configuration page. If there are items in red on that page I’d next recommend looking in the logs for more details information.

StorageZone Controller Monitoring page

The logs for the StorageZone Controller are located by default at c:\inetpub\wwwroot\Citrix\StorageCenter\SC\logs.

Within this directory multiple logfiles exist. The main ones you should check are:

  • cfgsrv_%date%.txt – StorageZone configuration logs
  • sc_%date%.txt – ShareFile StorageZone “ShareFile Data” logs
  • CIFS_%date%.txt – ShareFile StorageZone Connectors for Network File Shares logs
  • sharepoint_%date%.txt – ShareFile StorageZone Connectors for SharePoint logs

You can enable extended logging for…

November 21, 2013 Leave a comment

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.

Under the Covers of a Distributed Virtual Computing Platform – Built For Scale and Agility – via @dlink7, #Nutanix

November 21, 2013 Leave a comment

I must say that Dwayne did a great job with this blog post series!! It goes into expelling the Nutanix Distributed File System (NDFS) that I must say is the most amazing enterprise product out there if you need a truly scalable and agile Compute and Storage platform! I advise you to read this series!!

Under the Covers of a Distributed Virtual Computing Platform – Part 1: Built For Scale and Agility

Lots of talk in the industry about how had software defined storage first and who was using what components. I don’t want to go down that rat hole since it’s all marketing and it won’t help you at the end of the day to enable your business. I want to really get into the nitty gritty of the Nutanix Distributed Files System(NDFS). NDFS has been in production for over a year and half with good success, take read of the article on the Wall Street Journal.

Below are core services and components that make NDFS tick. There are actually over 13 services, for example our replication is distributed across all the nodes to provide speed and low impact on the system. The replication service is called Cerebro which we will get to in this series.
Nuntaix Distrubuted File System

 

This isn’t some home grown science experiment, the engineers that wrote the code come from Google, Facebook, Yahoo where this components where invented. It’s important to realize that all components are replaceable or future proofed if you will. The services\libraries provide the API’s so as newest innovations happen in the community, Nutanix is positioned to take advantage.

All the services mentioned above run on multiple nodes in cluster a master-less fashion to provide availability. The nodes talk over 10 GbE and are able to scale in a linear fashion. There is no performance degradation as you add nodes. Other vendors have to use InfiniBand because they don’t share the metadata cross all of the nodes. Those vendors end up putting a full copy of the metadata on each node, this eventually will cause them to hit a performance cliff and the scaling stops. Each Nutanix node acts a storage controller allowing you to do things like have a datastore of 10,000 VM’s without any performance impact… continue reading part 1 here

No it’s not Billy Gibbons, Dusty Hill, or drummer Frank Beard. It’s Zeus and Zookeeper providing the strong blues that allow the Nutanix Distributed File System to maintain it’s configuration across the entire cluster. Read more…

True Scale Out Shared Nothing Architecture – #Compute, #Storage, #Nutanix via @josh_odgers

October 26, 2013 Leave a comment

This is yet another great blog post by Josh! Great work and keep it up! 😉

I love this statement:

I think this really highlights what VMware and players like Google, Facebook & Twitter have been saying for a long time, scaling out not up, and shared nothing architecture is the way of the future.

At VMware vForum Sydney this week I presented “Taking vSphere to the next level with converged infrastructure”.

Firstly, I wanted to thank everyone who attended the session, it was a great turnout and during the Q&A there were a ton of great questions.

I got a lot of feedback at the session and when meeting people at vForum about how the Nutanix scale out shared nothing architecture tolerates failures.

I thought I would summarize this capability as I believe its quite impressive and should put everyone’s mind at ease when moving to this kind of architecture.

So lets take a look at a 5 node Nutanix cluster, and for this example, we have one running VM. The VM has all its data locally, represented by the “A” , “B” and “C” and this data is also distributed across the Nutanix cluster to provide data protection / resiliency etc.

Nutanix5NodeCluster

So, what happens when an ESXi host failure, which results in the Nutanix Controller VM (CVM) going offline and the storage which is locally connected to the Nutanix CVM being unavailable?

Firstly, VMware HA restarts the VM onto another ESXi host in the vSphere Cluster and it runs as normal, accessing data both locally where it is available (in this case, the “A” data is local) and remotely (if required) to get data “B” and “C”.

Nutanix5nodecluster1failed

Secondly, when data which is not local (in this example “B” and “C”) is accessed via other Nutanix CVMs in the cluster, it will be “localized” onto the host where the VM resides for faster future access.

It is importaint to note, if data which is not local is not accessed by the VM, it will remain remote, as there is no benefit in relocating it and this reduces the workload on the network and cluster.

The end result is the VM restarts the same as it would using traditional storage, then the Nutanix cluster “curator” detects if any data only has one copy, and replicates the required data throughout the cluster to ensure full resiliency.

The cluster will then look like a fully functioning 4 node cluster as show below.

5NodeCluster1FailedRebuild

The process of repairing the cluster from a failure is commonly incorrectly compared to a RAID pack rebuild. With a raid rebuild, a small number of disks, say 8, are under heavy load re striping data across a hot spare or a replacement drive. During this time the performance of everything on the RAID pack is significantly impacted.

With Nutanix, the data is distributed across the entire cluster, which even with a 5 node cluster will be at least 20 SATA drives, but with all data being written to SSD then sequentially offloaded to SATA.

The impact of this process is much less than a RAID…

How to: #Citrix #XenMobile 8.5 MAM upgrade! Part 2 – #StoreFront, #AppController, #NetScaler

September 9, 2013 1 comment

Hi again!

If you haven’t read Part 1 then I highly recommend doing so prior to going directly to the upgrade that we’re covering in this post!

Prepare for a journey in this post about Citrix StoreFront upgrade, uninstallation, console and how messy it could be! NOT all the time, sometimes it “just works”! 😉

My little NetScaler is already upgraded to 10.1 so unfortunately I couldn’t take you on that journey as well, so we’ll start with the StoreFront upgrade from 1.2 to 2.0 in this post. These are the steps that we need to cover as highlighted in the migration guide that seems very short and straight forward:

Upgrade StoreFront 1.2 to 2.0.

  1. Logon to the StoreFront server console.
  2. Upgrade StoreFront by running the StoreFront 2.0 installer as an administrator.
  3. When the upgrade is completed, open StoreFront administration snap-in, remove CloudGateway controller from each store as this will be moved in the migration solution.
  4. Open NetScaler Gateway Properties and for each gateway defined and change the version field in settings from 9.x to 10.0.x or later.
  5. Test the configuration by logging on through web browser or Citrix Receiver.
  6. Verify if the users are able to login and authenticate to StoreFront defined stores configured.

Is it this easy?

Ok, I’ve downloaded the 2.0 installer, and I’m logged on to the server.

Before we even start the upgrade there are things that could go wrong in removal or upgrades of StoreFront. And one that I’ve seen cause a lot of headache for a lot of people out there is that they have the Windows Firewall service disabled. Though the installation and removal wants to delete or add these rules the installation will fail unless this service is running. As you can see in this picture below you see the FW rule added in StoreFront 1.2:

Windows_FW_Rules_SF1

So let’s verify that the Windows FW service is started, and it is!

Windows_FW_SVC_started

I’ll now start the installation by double-clicking the StoreFront 2.0 installer!

StoreFront_2_0_Installer

What is this popup that came directly after starting the installer?

Receiver_HTML5_popup_installation

Wait, ok so you guys at Citrix couldn’t ask me whether you could do this for me? My plan is to upgrade, so please just add a little step in your upgrade program that does this for me… change request #1 for the next SF release and it’s upgrade process! Verify pre-requisites or deal with them!
