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.

#Nutanix – the ultimate Virtual Computing Platform for VDI – CBRC-like Functionality For Any #VDI Solution with #Nutanix – #IaaS – via @andreleibovici

February 3, 2014 Leave a comment

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 MethodSizing for VMware View Storage Accelerator (CBRC)View Storage Accelerator Performance BenchmarkCBRC and Local Mode in VMware View 5.1View 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:

  • 5 MB per GB of the VMDK size [hash-collision detection turned-off (Default)]
  • 12 MB per GB of the VMDK size [hash-collision detection turned-on]

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.

#VDI Calculator v5 is Now Available with Major New Features – #IaaS, #Storage, #BYOD via @andreleibovici

February 3, 2014 Leave a comment

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…
