After a lot of hard work, and a lot of late nights my new book Implementing Netscaler VPX is released!
The book covers
* Initial setup and deployment scenarioes
* Netscaler Gateway (SSL VPN, ICA proxy, Clientless access)
* Load balancing Exchange, SQL, TFTP, SharePoint, Citrix stuff
* Caching and Compression of web services
* High-availability, application firewall and traffic analysis with builtin tools and WireShark
* Appflow and integration with Netscaler Insigt.
The book can be found here http://bit.ly/QfCsqG at PacktPub website (Will soon appear on Amazon as well)
This is my second book for Packt Publishing and again has been a unique experience working with them. Would also like to give some credit to my techncial reviewers during the process Daniel Wedel, Kees Baggerman, Anton Van Pelt for giving good feedback.
Hopefully some will find it useful when working with Netscaler!
Today as promised, Citrix released XenApp & XenDesktop 7.5!
Which can be downloaded from mycitrix here – – –> http://bit.ly/1gXdots
This new release contains alot of new interesting features such as integration with SCCM for WoL and integration with Amazon for cloud provisioning (Azure will come later)
It also contains a new release of Storefront 2.5 which allows for SSO to web (Finally!)
You can take a closer look at the admin guide to read more about the new changes here –> http://citrix.edocspdf.com/media/output/en.xenapp-xendesktop.cds-xenapp-xendesktop-75-landing.pdf
I just received a email from Dell that I was awarded with their community title Dell Rockstar for 2014! For those who are not aware of what Dell Rockstar is, you can read more about it here –> http://en.community.dell.com/p/dcf-rockstars.aspx
This is indeed a huge honor and I personally hope that I can contribute to enhance the community even further!
A long time since I’ve written about certifications. A lot has happend since last time I wrote one of these blog post and this one will be more an internal note for my part but it’s always nice to plan ahead and get things written down, or it will never get done
For my part I’m working alot with virtualization and data center solutions (and of course cloud solutions) therefore I’ve decided to pursue a couple of certifications to validate my skills there. Now this year I’ve decided to start with these exams for cloud and virtulization.
CCNA Data Center (This exam covers alot of different network topics such as LACP, TRILL, implementing Nexus V1000 and such and gives a solid understanding of networking in a datacenter layer, this is recommended for people that already has a CCNA)
Amazon Web Services Certified (The cloud isn’t going away, neither is Amazon. They have already created a certification which covers how to use their own services like cloudformation, EC2 and such and gives you a good understanding of the services that amazon has in their public cloud)
Comptia Storage+ (Comptia is a neutral vendor certification company, Storage+ is an certifiaction that is made in cooperation with SNIA which covers all the basics regarding Storage)
Comptia Server+ (Server+ is much like Storage+ but goes into server hardware aspect)
Comptia Cloud+ (Covers all the different scenarois around cloud computing, like the different ways to deliver cloud solutions, what you need to think about before moving services to the cloud and such. Not a very technical exam but more about strategy and general knowledge
Now these exams aren’t very hard, but it is always good to have the validation that you poccess the knowledge needed
This is something I’ve been meaning to write for some time, since I see new tools and extensions added to System Center every day. Many of these extensions are powerful and free which many use in their day to day job. So therefore I decided to write down a list of those tools I know free or otherwise(cost money) for the System Center portofolia. This list shows the whole ecosystems around System Center and the possibilities it has! Im guessing that many here might be new to someone. Hopefully some of these tools are of use to you
And if someone knows of an extension or tool that is not on the list please leave a comment and ill add it to the list ASAP.
Virtual Machine Manager
Having been involved in a case for a long time now where a partner wanted to use SCVMM with XenApp 6.5 and PVS 7.1 for a customer and it has not been quite as successfull.
Now I wanted to share some notes with PVS and Hyper-V and what the limitations are there at the moment.
- First of it is important to note that PVS 7.1 is the only version of provisioning that supports SCVMM 2012 R2, as the support matrix lists.
- Using PVS with Hyper-V is now functional with PVS 7.1 this requires Legacy adapters in Hyper-V since Legacy adapters are the only NICs in Hyper-V that support PXE boot
- Citrix has implemented a failover mechanism between Legacy and Synthetic which means that the streaming traffic can start from the Legacy adapter and then switch to the synthetic.
- Hyper-V 2012 R2 does support PXE with Sythentic devices with Generation 2 Virtual Machines, but THIS IS NOT SUPPORTED BY CITRIX YET.
- If we for instance are using a VM with two Legacy adapters, Hyper-V will always boot from the last legacy NIC added to the virtual machine, if we are using “Stream VM wizard” in PXE it will add the first NIC in the virtual machine meaning that we get the wrong MAC address in the PVS database
- Hyper-V creates a new NIC GUID when creating a machine from a tempalte unlike Vmware or XenServer which does not.
- Stream VM wizard in PVS creates virtual machines from templates which means that NIC’s on the PVS virtual machines get reinitialized when booting and therefore service stop responding since it delays the network start.
- The only solution to this is to clone machines and then add them manually to PVS like in this CTX article –> http://support.citrix.com/article/CTX128750
- XenDestkop setup wizard in PVS DOES NOT create virtual machines from template, but clones the virtual machine using a set of PowerShell cmdlets.
Hopefully 7.5 has support for Generation 2 Virtual Machines!
While working on a Hyper-V project I was noticing that the virtual machines had very sluggish network performance. This was a brand new enviroment with a good bandwidth so therefore I was a bit stumped on why the Network was acting so sluggish.
After doing some testing we saw that the hyper-v host had about 100mbit access to the internet and low latency on the link. The virtual machine that was running on it with a shared network card has about 1/3 of the speed and was getting quite high latency when accessing the internet.
After playing around with the Network driver I tried disabling VMQ on the card and voila! everything worked perfectly. When I saw it was a Broadcom driver and did a quick google search I found that there is a known issue with Broadcom network adapter drivers and VMQ
You can read more about it here –> http://support.microsoft.com/kb/2902166
So if you are having trouble with virtual machines and sluggish network performance with Broadcom drivers, try disabling VMQ
NOTE: I had added the latest Broadcom drivers to the hyper-v host but they did not fix the issue, I contacted Broadcom which gave me a hotfix which I used in this instance.
So I see more and more questions regarding Office365, and therefore I suggest looking on this exam , Administering Office 365 for Small Businesses 74-325 https://www.microsoft.com/learning/en-us/exam-74-325.aspx
I have taken the exam so therefore I wanted to create a study guide to make it easier to study for this exam. First of I suggest looking at the jumpstart on Microsoft Virtual Academy which covers most of the topics. (This requires a MVA account) http://www.microsoftvirtualacademy.com/training-courses/administering-office-365-for-small-business-jump-start
Important to note that this exam is purely multiple choice and remember to read the questions carefully.
Also remember to take note of the different PLANs and the amount of users and what it includes in data storage.
I have also added technet articles under each topic. So this is what the exam covers:
Provision and manage users, groups, and domains
Prepare the client computer and configure remote connectivity
Manage mailboxes, contacts, and groups
Manage messaging security and compliance
Manage Lync in an Office 365 environment
