#Hyper-V 2012 R2 Network Architectures Series (Part 1 of 7) – Introduction

This is a great blog post series! Good job Cristian Edwards!

Hi Virtualization gurus,

Since 6 months now, I’ve been working on the internal readiness about Hyper-V Networking in 2012 R2 and all the options and functionalities that exists and how to make them work together and I realize that a common question in our team or from our customers is what are the best practices or the best approaches when defining the Hyper-V Network Architectures of your Private Cloud or your Virtualization farm. Hence I decided to write this series of posts that I think they might be helpful at least to do the brainstorm to find the best approach for every particular scenario. The reality is that each environment is different and use different hardware, but at least I can help you identify 5 common scenarios on how to squeeze the performance of your hardware.

I want to make clear that there is no just one right answer or configuration  and your hardware can help you determine the best configuration for a robust, reliable and performer Hyper-V Network Architecture.  Please note that I will do some personal recommendation based on my experience. These recommendations might or might not be the official – generic recommendations from Microsoft, so please call you support contact in case of any doubt.

The series will contain these post:

#Citrix #StoreFront 2.5.2 is released – #DaaS, #XenDesktop, #XenApp

Citrix has released Citrix StoreFront 2.5.2 with some good fixes…

Issues fixed in StoreFront 2.5.x

Updated: 2014-06-18

Issues fixed in StoreFront 2.5.2

Fail to launch a XenApp session from the second delivery site.

The StoreFront server had problems with load balancing between two XenApp farms. When the first farm was completely loaded, StoreFront did not use the second farm and the application launch failed. [#432279]

Enhanced enumeration fails with socket pooling enabled.

Enumeration failed for two or more farms when socket pooling was enabled in the store configuration file. [#470666 and #458139]

Issues with finding the domain controller for a domain.

Slow logon times occurred when geographically distant domain controllers were chosen. [#479210]

Submitting the logon form after the authentication service session timed out results in an HTTP 400 Bad Request.

When the logon form was submitted after the authentication service session timed out, an HTTP 400 Bad Request response was generated preventing the user’s credentials from being resubmitted. [#479200]

Directory queries are not thread-safe.

Citrix default Domain Services crashed because the Directory services account look-up was not thread-safe. [#479188]

Issues fixed from StoreFront 2.1 to 2.5

Changing an expired password on next logon fails.

When prompted to change a password, client domain users using Windows would not be able to successfully change their passwords because of Windows Server 2003 domain controllers failing to handle the operation correctly. Microsoft has issued an update that resolves this problem. The update is available via Windows Update or may be downloaded from Microsoft support directly at http://support.microsoft.com/kb/2927811. [#438725]

A user with a large number of subscriptions loses the ability to manage subscriptions.

When logging on, users with 353 or more automatic app subscriptions would receive the following error: “Citrix Receiver cannot currently add, remove, or reposition apps.” [#432086]

The wrong user name is sometimes shown.

Clients would erroneously display a different username. [#430823]

PNA resource IDs do not match requirements of local launch logic.

PNA resources from XenApp were in a format different than StoreFront’s usage. This inconsistency led to slower performance due to excessive ICA connections.[#429055]

Partial wildcard certificates cause issues in the admin console.

The admin console would improperly display configured host names from the IIS bound certificates. [#424708]

Change password option is not available for some users.

Some users were not given the option to reset their password even though they were enabled to do so. [#416373]

Subscription export/import loses subscription properties.

StoreFront was not properly maintaining multiple subscription properties. [#408668]

DAC smart card authentication updated to use domain account services rather than IIS certificate mapping.

Desktop Appliance Connector certificate authentication with smart cards required manual configuration with IIS certificate mappings rather than using the default domain account services. [#406945]

A SAN web server certificate with no CN causes issues for the admin console.

StoreFront admin console was improperly handling common name entries in certificates which would cause console crashes.[#401815]

StoreFront home farms support gives a user access to all farms when they should have access to none.

When a user was configured without access to any farms, all farms were enumerated for that user.[#400869]

The admin console being closed would overwrite some manually applied changes made to the configuration file.

Some manual configuration changes were being lost when the admin console was closed. [#440946, #424460, #439887, #395155]

#Nutanix is the Visionary leader in #Gartner magic quadrant! – #IaaS, #PaaS, #DaaS, #Storage, #Converged

I’m not surprised at all and think that this is a good report by Gartner!

Nutanix is absolutely the visionary leader and once more and more units are shipped they will also climb higher into the leaders section and totally rule! I must say that this is a really impressive product that truly is web-scale ready for SMB to large enterprise workloads!! Contact us at EnvokeIT if you need more details! We know the product and how it can deliver value to you!

magic_quadrant_for_integrated_systems_nutanix

The integrated system market is growing at 50% or more per year, creating an unusual mix of major vendors and startups to consider. This new Magic Quadrant will aid vendor selection in this dynamic sector.

Nutanix has close working relationships with multiple top software vendors, and workloads like VDI, Hadoop and DBMS servers are well-represented among the installed base. Maximum neutrality is a major focus for Nutanix, as it works to build trust across a wide variety of vendors. The vendor frequently targets specific workload needs to penetrate new accounts, and then expands the workload reach to compete with incumbent vendors as client confidence is built. Nutanix claims that 50% of first-time clients expand their configurations within six months (and 70% do so within 12 months).

Market Definition/Description

Integrated systems are combinations of server, storage and network infrastructure, sold with management software that facilitates the provisioning and management of the combined unit. The market for integrated systems can be subdivided into broad categories, some of which overlap. Gartner categorizes these classes of integrated systems (among others):

  • Integrated stack systems (ISS) — Server, storage and network hardware integrated with application software to provide appliance or appliancelike functionality. Examples include Oracle Exadata Database Machine, IBM PureApplication System and Teradata.
  • Integrated infrastructure systems (IIS) — Server, storage and network hardware integrated to provide shared compute infrastructure. Examples include VCE Vblock, HP ConvergedSystem and IBM PureFlex System.
  • Integrated reference architectures — Products in which a predefined, presized set of components are designated as options for an integrated system whereby the user and/or channel can make configuration choices between the predefined options. These may be based on an IIS or ISS (with additional software, or services to facilitate easier deployment). Other forms of reference architecture, such as EMC VSPEX, allow vendors to group separate server, storage and network elements from a menu of eligible options to create an integrated system experience. Most reference architectures are, therefore, based on a partnership between hardware and software vendors, or between multiple hardware vendors. However, reference architectures that support a variety of hardware ingredients are more difficult to assess versus packaged integrated systems, which is why they are not evaluated by this research.
  • Fabric-based computing (FBC) — A form of integrated system in which the overall platform is aggregated from separate (or disaggregated) building-block modules connected over a fabric or switched backplane. Unlike the majority of IIS and ISS solutions, which group and package existing technology elements in a fabric-enabled environment, the technology ingredients of an FBC solution will be designed solely around the fabric implementation model. So all FBCs are an example of either an IIS or an ISS; but most IIS and ISS solutions available today would not yet be eligible to be counted as an FBC. Examples include SimpliVity, Nutanix and HP Moonshot System.

GotoMeeting Free – yes, free collaboration!! – #Citrix, #GotoMeeting

Well, I can’t count the number of times that I’ve heard people saying that they wished they had GotoMeeting licenses or a similar capability that is free… and what just happened!?! Citrix released a free version! :-)

It of course has some limitations and lack of capabilities compared to the full service you get when being it, but if you can survive with using a Chrome browser to collaborate with you colleagues, friends and loved ones then this is a great service!

Citrix GoToMeeting Free

Mathieu Hofman, researcher and developer of GoToMeeting Free, and Eric Bensley, GoToMeeting Senior Product Manager, explain what motivated them to create the newest member of the GoToMeeting product line, GoToMeeting Free.

Hi, Mathieu and Eric here. We are really excited about the launch of GoToMeeting Free! This started simply as technology innovation and now has evolved into the latest addition to our award-winning communications solutions. GoToMeeting Free is an entirely free, browser-based (Chrome), unlimited-use video conferencing product for up to three people. And we made it simple: no need to log in, download additional software, or enable plug-ins.

When our teams first began working on this product it was not about adding to GoToMeeting but rather seeing what would happen if we took great technology – Chrome and WebRTC – and created something that would let people connect instantly in a face-to-face experience. In our efforts there were a few things we aimed to address:

  • Eliminate the need for downloads by running from a browser
  • Make getting into sessions fast and efficient – no sign up, no access codes, just click and go
  • Deliver a high quality video and audio experience
  • Available in Chrome Web store

The result: GoToMeeting Free is like the “casual coffee” of meetings by removing the barriers to quickly connecting with anyone in a meaningful way…

And here you have some other details from the GotoMeeting blog:

What You Need to Know about GoToMeeting Free

The cost of doing business these days can be daunting. And with the growth of small-business startups comes the need for low-cost and highly collaborative software solutions. Enter GoToMeeting Free.

What is GoToMeeting Free? It’s an entirely free addition to the Citrix collaboration suite that offers unlimited-use video conferencing for up to three people. And did we mention it’s completely browser-based in Google Chrome? Meaning no need to download any additional software.

Who can use GoToMeeting Free? Everyone. GoToMeeting Free was designed with lean startups and entrepreneurs in mind, but this software is open to anyone with Chrome, a webcam and a reliable Internet connection.

Why use GoToMeeting Free? If you are hosting small informal meetings for dispersed teams or your office doesn’t have the budget for a company-sponsored video conferencing account, then this is the solution. There’s no limit to the amount of meetings you can host, and it allows you to connect instantly with a face-to-face experience.

We wanted to build tool that was something that we would use ourselves, so here are a few of the areas we looked to address:

  • No pesky software downloads. Because GoToMeeting Free runs from a browser (Chrome), there’s no need to download additional software. Just send your attendees the link and join the meeting – it’s that easy.
  • Faster join times. Because there is no software to download, no sign-up required and no access codes needed, all you need to do is simply click to connect instantly.
  • High-quality video and audio experience. Using WebRTC technology we were able to create a product that would allow small audiences to connect seamlessly with no dial-in required.

We’ve gotten rave reviews so far on the simple and straight-forward experience of GoToMeeting Free. And we are in development for additional features that will allow teams an even higher lever of collaboration in the near future. We hope you’ll try it out.

#XenMobile and the #Citrix Mobile Workspaces Architecture – #BYOD

This is a great blog post by Christopher Campbell and good picture to show the overall capabilities and architecture of the Citrix offering!

You’ve heard us talk about Mobile Workspaces and if you’re a techie you’re probably wondering if Citrix really has the architectural components (a complete, comprehensive and fully integrated architecture) that can deliver any app and data to any user on any device over any network?

Well let’s first identify a few of the market leading technologies that make up the Citrix Mobile Workspaces solution:

  • XenApp mobilizes and secures Windows apps on any device
  • XenDesktop securely delivers virtual Windows desktops and apps on any device
  • XenMobile manages and secures mobile, web and SaaS apps on mobile devices
  • GoToMeeting empowers people to meet and collaborate with anyone, anywhere
  • ShareFile shares and syncs corporate data securely from any location
  • NetScaler optimizes and secures app delivery and on any network
  • CloudPlatform orchestrates and provisions apps, desktops and IT services from any cloud

OK, OK. We know you have the products but do they really integrate?

Yes. Don’t believe me? Well as they say a picture is worth a thousand words. This is what the Mobile Workspace Architecture looks like.

OK. I get it.  You have the architecture but that doesn’t necessarily translate to a seamless user experience.

Still don’t believe huh? Well this is what the user experience looks like.

XenMobile is a key ingredient in delivering a mobile workspace.  Along with XenApp and XenDesktop it allows organizations to deliver on giving users access to any app from any device. In fact, if you’re an existing XenApp or XenDesktop customer, XenMobile seamlessly plugs into your existing architecture.

If you’re a XenDesktop or XenApp customer this is what your environment probably looks like.

Now this is what you need to enable EMM for BYO and COPE (Corporate Owned, Personally Enabled) devices and add that MDM, MAM, Secure Email, Secure Data…
