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:
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…

It’s really great to see the capabilities of the Nutanix platform! Just read this great blog post by @andreleibovici around Content Based Read Cache (CBRC) and how this isn’t necessary at all on a platform like Nutanix!
Conclusion
Overtime I will discuss more about the technology behind Content and Extent Caches. For now what is important to know is that Nutanix provides a better in-memory microsecond latency benefits provided by CBRC for any VDI solution on any of the aforementioned hypervizors, for both Linked and Full-Clones. In fact, Nutanix engineers even recommend Horizon View administrators to disable CBRC because the Nutanix approach is less costly to the overall infrastructure.
It is amazing when your world turns upside down and a technology that used to be awesome becomes mostly irrelevant. It amazes me how fast technology evolves and help organizations to achieve better performance and lower OPEX.
For a long time I have discussed the benefits of CBRC (Content Based Read Cache) available with Horizon View 5.1 onwards, allowing Administrators to drastically cut-down on read IO operations, offloading the storage infrastructure and providing greater end-user experience.
Here are few of the blog posts I wrote on CBRC technology: Understanding CBRC (Content Based Read Cache), Understanding CBRC – RecomputeDigest Method, Sizing for VMware View Storage Accelerator (CBRC), View Storage Accelerator Performance Benchmark, CBRC and Local Mode in VMware View 5.1, View Storage Accelerator (CBRC) Hashing Function.
CBRC helps to address some of the performance bottlenecks and the increase of storage cost for VDI. CBRC is a 100% host-based RAM-Based caching solution that helps to reduce read IOs issued to the storage subsystem and thus improves scalability of the storage subsystem while being completely transparent to the guest OS. However, CBRC comes at a cost.
When the View Storage Accelerator feature (CBRC) is enabled, a per-VMDK digest file is created to store hash information about the VMDK blocks. The estimated size of each digest file is roughly:
The digest file creation for a large replica disk can take a large amount of time and a bulky quantity of IOPS, therefore it’s is recommendable not to run the operation, create new desktop pools, or recompose existing pools during production hours.
CBRC also uses a RAM to manage the cached disk blocks. The per-VMDK digest file is also loaded into memory. That is the reason why CBRC should not be enabled under memory-overcommit environments. If a host is memory over-committed and CBRC is enabled – the memory pressure is increased as CBRC also uses memory for the cache. In such cases, the host could experience increased swapping and the overall host performance could be impacted.
Whilst I wrote about CBRC benefits, I also received numerous negative comments about the technology, including lack of support for full-clone desktops, being unsupported for layering tools like Unidesk, and taking too long to generate new hashes for every replica.
CBRC is a platform feature (vSphere), however it is only enabled and available via Horizon View. Other VDI products such as XenDesktop or vWorkspace cannot utilize the feature.
Nutanix suppress the need for CBCR, providing similar functionality to any VDI solution running on top of vSphere, Hyper-V or KVM. Nutanix has a de-duplication engine built into the solution that works real-time for data stored in DRAM and Flash.

This is awesome! Great work by @andreleibovici!
I am happy to announce the General Availability of the new VDI Calculator v5. This new version is the single biggest release since I started delivering the calculator. I have completely re-architected the way the calculator works, allowing multiple types of desktops to be configured in a single calculation for a single solution.
All existing features have been retained and will work in the exact same way you are used to, but you now have the ability to select different options for different types of desktops or desktop pools.
As an example, you may choose Desktop Type 1 to be a ‘student’ desktop using Linked Clones with 10 different pools; conversely you may choose Desktop Type 2 to be a ‘professor’ desktop using Full Clones with 5 individual pools. This new calculator gives you much more granular control over your calculations eliminating repetitive tasks when sizing larger environments.
To enable multi-desktop pool calculations just select ‘-’ and ‘+’ in the top bar menu.

Another additional feature is what I call ‘Ask for Help‘. During the application session when you select the Update option a new screen will show up asking if you would like to be contacted by VDI solutions vendors that can help reduce costs, improve performance or improve manageability of your VDI solution. If you are interested…

Wow, this is great!
Nutanix Sr. Systems Engineer, Tim Federwitz (@VirtuallyGeeky), created a nice interactive mock-up of the Nutanix Prism Administrative Interface.
In Tim’s own words, “I have created a VERY simple, but somewhat functional, slightly interactive look at the Nutanix Prism GUI (the Nutanix Web Console). You can use it from pretty much any device, including mobile phones and tablets. Click or tap on the various items in the GUI to navigate around the different screen captures. The screenshots are all static, of course, but at least you get to see the different screens and features.
It is still in its infant stage as I threw it together in a few hours last Sunday night. I plan on finishing up the screens I didn’t have time for, but feel free to use it as it comes together. I am “releasing” it early as there seems to be a LOT of interest in something like this.
I really created it to easily show potential customers what the Web Console looks like and highlight some of the features and ease of use that it brings. Along with showing how VM centric and granular…

Yes, why do people and organisations still think that they can build IaaS/PaaS/DaaS services within their enterprise’s and believe that they will be able to do so with the “same old architecture” and components used before? It’s not going to be comparable to the bigger players that are using newer and more scalable architectures with cheaper components.
Enterprises just don’t have that innovation power that companies like Google, Facebook and Amazon has! And if they do then most of the time they are stuck in their old way of doing things from a service delivery point of view, stopping them from thinking outside of the box though the service delivery organisation isn’t ready for it..
This is a great blog post on this from Brian, great work!!
Last month I wrote that it’s not possible for you to build VDI cheaper than a huge DaaS provider like Amazon can sell it to you. Amazon can literally sell you DaaS and make a profit all for less than it costs you to actually build and operate an equivalent VDI system on your own. (“Equivalent” is the key word there. Some have claimed they can do it cheaper, but they’re achieving that by building in-house systems with lower capabilities than what the DaaS providers offer.)
One of the reasons huge providers can build VDI cheaper than you is because they’re doing it at scale. While we all understand the economics of buying servers by the container instead of by the rack, there’s more to it than that when it comes to huge cloud provider. Their datacenters are not crammed full of HP or Dell’s latest rack mount, blade, or Moonshot servers; rather, they’re stacked floor-to-ceiling with heaps of circuit boards you’d hardly recognize as “servers” at all.
Building Amazon’s, Google’s, and Facebook’s “servers”
For most corporate datacenters, rack-mounted servers from vendors like Dell and HP make sense. They’re efficient in that they’re modular, manageable, and interchangeable. If you take the top cover off a 1U server, it looks like everything is packed in there. On the scale of a few dozen racks managed by IT pros who have a million other things on their mind, these servers work wonderfully!
This is great! A great product takes another award!!! 😉
V3 Readers Award Nutanix with Prestigious Industry Recognition in Highly Competitive Category

Good article and I must agree that OpenStack has quite a long way to go before the “average” enterprise embraces it…
OpenStack still has maturing to do before it’s really ready for the enterprise, analyst says
Network World – Gartner analyst Allessandro Perilli recently attended his first summit for the open source cloud platform OpenStack and he says the project has a long way to go before it’s truly an enterprise-grade platform.
In a blog post reviewing his experience, the analyst – who focuses on studying cloud management tools – says that OpenStack is struggling to increase its enterprise adoption. Despite marketing efforts by vendors and favorable press, enterprise adoption remains in the very earliest stages, he says.
Don’t believe the hype generated by press and vendor marketing: OpenStack penetration in the large enterprise market is minimal.— Gartner analyst Alessandro Perilli
Sure there are examples like PayPal, eBay and Yahoo using OpenStack. But these are not the meat and potatoes types of enterprise customers that vendors are looking to serve. Why? He outlines four reasons, most of which are related to the process and community nature of the project, and less around the technical maturity of it. By the way, this is not the first time a Gartner analyst has thrown cold water on the project.
[EARLIER CRITICISMS FROM GARTNER: Gartner report throws cold water on OpenStack hype]
Lack of clarity about what OpenStack does
There is market confusion about exactly what OpenStack is, he says. It is an open source platform that can be assembled together to build a cloud. It, by itself, is not a cloud though just by downloading and installing it. OpenStack requires some heavy lifting to turn the code into an executable cloud platform, which is why dozens of companies have come out with distributions or productized versions of OpenStack code. But, the code itself is not a competitor to cloud platforms offered by vendors like VMware, BMC, CA or others. Read more…
This is really cool!!! Great job as usual Nutanix!!
Enterprises continue to embrace converged scale-out architectures to make their datacenters simpler and easier to manage. Nutanix—the leader in converged infrastructure—brings these benefits to all parts of enterprise IT, providing the flexibility and power to run any virtual workload within a single infrastructure. Nutanix has added several new products to its family of Virtual Computing Platforms:
NX-7000 series platform for
powering graphics intensive users
Virtual desktop computing has become mainstream in all size organizations, and throughout all industries. Despite its successful and pervasive enterprise deployment, virtual desktop infrastructure (VDI) has been unable to deliver many graphics-intensive applications and services with the same level of performance as when running on physical workstations.
To address this need, Nutanix has partnered with NVIDIA and Teradici to broaden its VDI portfolio, and integrate cutting edge acceleration for graphics rich desktops. The NX-7110 supports configurations with both NVIDIA GRID K1
and K2 GPU technology, as well as Teradici PCoIP APEX cards. The Nutanix Virtual Computing Platform is the industry’s first converged infrastructure to support every type of VDI user, from task and knowledge workers to power and data scientists. Leveraging VMware’s SVGA driver technology along with NVIDIA GRID, the NX-7000 supports multiple rendering models, including Soft 3D, vSGA and vDGA.
Existing Nutanix environments can dynamically deploy NX-7110 appliances into a unified cluster that is centrally managed, while maintaining graphics intensive users in a separate desktop pool. Additional benefits include the delivery of maximum compatibility and portability to any user. For the first time, organizations have the confidence to move away from more expensive and rigid physical workstations, and virtualize their entire portfolio of desktops. The NX-7110 is now generally available.
NX-6020 delivers more economical
data storage
The NX-6020 supports VMs with very large datasets, such as SQL databases, big data
analytics projects and VDI deployments with full clones. It provides a 25% increase in available capacity. With both in-line and post-pr
ocess compression, it delivers between 42TB and 68TB of effective capacity in a space-efficient 2U platform. In addition, Nutanix has focused on cost-reducing other components within the appliance delivering a more economical data storage solution.
NX-3000/6000 series gets more powerful CPUs for 30% faster performance
Nutanix has updated the existing NX-3000 and NX-6000 product families with four new platforms featuring Intel’s Ivy Bridge server CPUs. As a 100% software-defined solution, Nutanix Virtual Computing Platform can rapidly adopt new technologies.
These new appliances benefit from 25% more CPU cores, faster clock speeds and a reduced power profile. This translates to a 30% increase in performance for VMs running on Nutanix, as well as support for higher VM densities. Each of these new platforms can be seamlessly added to any existing Nutanix cluster to immediately take advantage of the most advanced CPU technologies.

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.

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.
