“In just two weeks we had a Nutanix cluster up and ready for new business in the AWS public cloud. As well as meeting our immediate deadline, this allowed us to still meet geographic constraints and other regulatory requirements. Plus it can run all our workloads unchanged and be managed remotely along side other on-premises private cloud deployments”. Don’t let supply chain headache’s get you down when you need control and choice for your business systems and projects. Nutanix Hybrid Multi-Cloud Platform, with One Click operations and built-in automation, allows any workload at any scale to run in any cloud (including your private cloud) with your choice of financial model, be it capex or opex, giving you maximum choice and maximum control. Workload mobility with consistent management has never been this easy. Build a solid foundation for digital transformation with the industry’s best technical support to back it all up.

Your infrastructure on your terms.

The COVID pandemic years have presented many curve balls to organisations of all shapes and sizes. Now more than ever it’s important to have infrastructure that supports ever changing business objectives and provides agility and flexibility at short notice. With Nutanix Hybrid Multi-Cloud Platform workloads can be moved between clouds, including private clouds, with a few simple operations, without the need to refactor the applications. Traditional applications are supported along side K8’s and modern cloud native applications and big data. Organisations can take advantage of new revenue opportunities by scaling infrastructure rapidly and aligning costs to allow profitable growth, all while maintaining consistent and simple management across all platforms.

No need to compromise.

Benefit from decreasing costs with predictable performance and easy management and troubleshooting, while reducing risk of downtime across all of your cloud platforms. Linear scalability with predictable performance removes some of the question marks about how applications will behave regardless of the cloud they are running in. While cloud hardware might be transient in some cases, smart infrastructure software can protect your data and applications even in the situation of maintenance and failure. Spend less time troubleshooting and more time innovating and differentiating against the competition.

Enhanced Productivity and Innovation for All!

Business initiative being more successful than planned? Needing additional capacity earlier than planned? Wanting to allow for a seasonable peak in demand? No problem. Scale out infrastructure in a few minutes or on demand automatically with supported cloud providers. Fractional consumption of IT resources regardless if they are local, hosted or cloud based. Use existing cloud accounts and access existing cloud credits and all native services directly (on same VPC) from the local cloud provider. No need to set up brand new cloud accounts with the Nutanix Hybrid Multi-Cloud Platform!

Enterprise Strategy Group – ESG, recently completed a evaluation of Nutanix Cloud Platform for Enterprise Workloads and Databases, covering MS SQL Server, Oracle, SAS Analytics, Splunk, and VDI. The results compare performance from 2017 to 2021, and as you expect show some impressive improvements. One thing that shines through is the linear scalability and stability of the Nutanix platform. The performance you get with one node, you get each time you add a node, making performance and capacity scale easily without complications. You can access the full report here, this post will cover some of the brief highlights.

The report (download here) highlights that Nutanix Cloud Platform can simplify infrastructure supporting any enterprise workload or database, and provide consistent, repeatable, and linearly scalable performance with high availability. The elastic scalability and fractional consumption of the Nutanix Cloud Platform can benefit any type of workload, and create a cloud experience wherever a customer chooses to deploy it.

The following image displays the availability graph across Nutanix systems globally and demonstrates high levels of availability can be expected (not included in the report).

Nutanix Cloud Platform Global Availability

Two areas I would like to highlight from the report is the MS SQL Server and VDI Performance, both demonstrate the consistent performance and scalability of the Nutanix Cloud Platform, and low latency that can be expected.

SQL Server Performance and Scalability

VDI Login VSI Response Times Performance and Scalability

As workloads are added, and nodes are scaled, overall performance increases and response times stay consistent. The report covers many more workloads and has special features to note applicable to big data workloads, such as SAS Analytics, Splunk or Elastic Search. I would recommend you download the full report (download here) and read through it, as it’s only 20 pages.

Final Word

Enterprise workloads and databases need a solid underlying infrastructure to ensure optimal business results. The Nutanix Cloud Platform allows a customer to deploy the same consistent infrastructure in public cloud, co-lo, or on-prem and experience the same reliability and linear scalability. Choose your location, build your cloud, all on your terms.

A while ago I wrote about how Nutanix was Shrinking the Datacenter with a box that packed a big punch, at least for demo, home lab (Community Edition), and similar non-production use cases. Now I’m pleased to report that Nutanix has created a new NX node suitable for enterprise use as small remote office / branch office (ROBO), and small datacenter and space constrained use cases. The NX1120S-G7 is a hot new platform, available for sale now, for all of the small use cases that were hard to cost justify previously. Below are some of the highlights of the new platform.

Here is a full datasheet for the NX1120S-G7.

Because the NX1120S is 1U and short depth it’s suitable for many different applications, including in small, tight spaces, such as aboard ships, subs, and in closets, or even drawers. This platform would work for the gas / petrol station shop front beside or under the cash register, in hotel properties, or any retail or ROBO use cases, and it only draws 180W of power. These nodes could be good for mining, even inside some of the big mining equipment to run their local IT needs where availability is critical and downtime is costly.

From the time the nodes arrive on site they could be set up and in use within a couple of hours. Nutanix award winning Prism user interface allows control of all major functions, and Prism Central can be used from a main location to control all ROBO sites across an enterprise. Combines with Nutanix award winning support for both hardware and software you have a single vendor solution for all your ROBO and small datacenter needs.

Even though the size of the node is small, with only a 10″ depth, it is incredibly powerful. These nodes really do pack a punch. We have successfully tested them under a full ERP workload with PeopleSoft with 5000 concurrent users. Although mission critical datacenter apps aren’t the primary use case, they do demonstrate how much power these nodes have.

Final Word

Up until now the complexity and cost of supporting thousands of remote sites and small datacenters has been high. Nutanix NX1120S-G7 solves this problem and delivers a platform suitable for space and power constrained use cases across many different industries, allowing high availability and efficiency where it may not have been economical to provide in the past. Over time the capability of these nodes will increase and we’ll be able to pack even more power in an ever smaller space. How can you utilize something like this for your business?

Managing large databases is hard. Having changes go through a dynamic environment to production with thorough testing is also hard. When you have a 100TB+ production system, keeping non-production copies up to date is even harder still. Most companies can’t afford to keep exact copies of production due to the size and scale, so compromise the non-production environments. This is no longer necessary. Nutanix Era solves this acute database management problem, and many others!

Nutanix Era is a Database-as-a-Service Solution that solves many of the acute problems facing businesses and DBA’s today when managing large number of databases, or large databases, which impact productivity, reliability, availability and performance.

One of the biggest benefits for customers that have large databases is the ability to take a complete clone of the production system and make multiple copies for non-production uses. Any number of clones can be created without impacting storage capacity requirements, this is due to using native Nutanix API’s in the cloning process. The following 9 minute video shows an example of a 100TB Production Oracle RAC DB being refreshed to 10 clones, for use in testing and development. The clones don’t take up any additional space until the moment data is changed. I hope you like the Jazz music :).

If you like what you see and you’d like to get some hands on experience with Nutanix Era, please take a look at the Nutanix Era Test Drive – Available Online from the comfort of wherever you are.

Recently version 2.0 of Era was released, including the following enhancements.

Hybrid Cloud Flexibility and Multi-cluster Management

With Era 2.0 we have extended our database platform capabilities across clusters and hybrid cloud. This provides our customers the flexibility to build and manage databases on their own terms, giving them the freedom to develop and deploy databases of their choice in the environment they want.

Expanding Database Engine Portfolio with SAP HANA

SAP/HANA has joined Oracle, MS SQL Server, PostgreSQL, MySQL, & MariaDB in the portfolio of database engines supported by Nutanix Era. SAP/HANA customers can now leverage Era’s 1-click capabilities to create an end-to-end sandbox environment on the Nutanix HCI platform.

Extended Choice and Support with PostgreSQL

With Era 2.0, PostgreSQL admins can now take full advantage of all Era capabilities, including patching and in-place restore. In addition, Nutanix will now provide 24×7 support for PostgreSQL databases provisioned by Era, allowing customers to call our support number with any issues.  

Enhancing Service Model Delivery with HCL Partnership

For customers seeking fully-managed database services, Nutanix has partnered with global technology company HCL, to offer a joint solution called SKALE DB powered by HCL and Nutanix. The partnership provides a secure, scalable, cloud-ready managed DBaaS offering integrated with Nutanix Era and Prism for automation and management for database & hyperconverged infrastructure.

There is much more to come in future releases!!

Final Word

Good DBA’s are far too valuable to allocate to mundane tasks that can be automated. The DBA’s can create and control the policies, and delegate to competent team members the rights to perform tasks for themselves. DBA’s can then focus on solving real business problems, improving data efficiencies and delivering far greater insights. Utilising Nutanix Era can greatly reduce the storage required to manage database environments and maintaining large numbers of non-production systems. The capital saved from not needing excess storage infrastructure can be redeployed to more business focused investments. There is no need to migrate defects to production because you couldn’t test changes on a full scale copy in your non-production systems! Don’t forget to get some hands on experience with Nutanix Era, please take a look at the Nutanix Era Test Drive – Available Online from the comfort of wherever you are.

All around the world thousands of customers trust Nutanix with their critical infrastructure, be that for core banking, financial markets, insurance, healthcare, manufacturing, retail, telecommunications, and Government. Nutanix has built cloud technology that is capable of providing robust high availability and predictable performance both on-prem, and in public cloud environments. Nutanix has proven suitable for not just mission critical and business critical environments, but also life critical environments. This is one of the reasons why it was an obvious choice for SAP to work with Nutanix. SAP systems process (in some form) approximately 76% of the worlds GDP, and they are the leading ERP software maker. In Nutanix’s latest certification for SAP HANA Scale Out we produced a very impressive performance benchmark, to add to the simplicity, scalability and availability we have bought to SAP HANA solutions for a while now.

The first SAP Certification for Netweaver was in 2016 (a first for an HCI vendor) and two years later Nutanix became the first vendor to pass the new SAP HANA HCI Certification, which Nutanix helped develop jointly with SAP. Therefore it seems only fitting that now in 2020, Nutanix is the first vendor of Hybrid Cloud Infrastructure to have passed the SAP HANA Scale-Out Certification, and published an impressive BWH benchmark jointly with our development partner Lenovo to go with it.

Everyone that works with SAP knows how seriously they take their certification processes and how strict the criteria and SLA’s are that need to be met. All of the results for the certification had to be directly compared to bare metal solutions. Nutanix with AHV proved extremely capable for both Scale Up HANA, and now for Scale Out HANA, due to our unique data locality.

With Nutanix Data Locality we can provide consistent and predictable performance as nodes are scaled out in a SAP HANA environment. This prevents the traditional bottlenecks that exist with three tier storage systems. Every node has dedicated local storage resources that are pooled across the cluster and grow performance and capacity linearly as the environment grows. The Nutanix SAP HANA Scale Out Solutions is certified for up to 6 nodes x 4.5TB (6TB physical RAM per node) for 27TB of RAM total. If any customers have larger needs for scale out BWH solutions we’d be happy to talk to you about your requirements.

Final Word

With Nutanix world leading support and direct integration into SAP, customers can have confidence in deploying SAP solutions on top of Nutanix infrastructure. There are a lot more exciting developments on our roadmap that will be announced in the future. If you have any projects that require SAP and you need a highly available, scalable, predictable, and consistent platform, you should talk to Nutanix.

In the rapidly changing work from home world you need agile applications and infrastructures. RedHat has built a great containerized platform for agile applications in OpenShift. To get the most out of the OpenShift platform you need a great scalable and highly available infrastructure. This is where Nutanix comes in and the combination of the two is a cloud you control with the application flexibility you need, no matter where it’s hosted.

Nutanix provides an on premises or cloud based linearly scalable infrastructure platform that is suitable for running any application. Nutanix AOS software and AHV Hypervisor can group together industry leading server technology to create a scale out cluster of resources. Performance scales as you scale node numbers. Availability is assured by the underlying infrastructure software, which ensures no single points of failure. The actual deployment can be in your datacenter, a public cloud, or the hosted environment of your choice. Deployment of the infrastructure takes minutes, then you can quickly get RedHat OpenShift up and running.

Nutanix Cluster Annual Availability Rolling 12 Months

Unlike many public cloud environments that only provide 99.5% availability in their SLA’s, Nutanix AOS software can provide 99.999% or above availability, as measured across the global fleet of customer clusters, which is depicted above. If you wish to deploy containerized applications on top of such an scalable and available infrastructure, you could get above 6 nine’s of availability, which is great for many types of critical applications. Smart applications, combined with smart infrastructure, you get significantly higher availability, to go along with your scalable performance.

If you’d like to see how to get RedHat OpenShift up and running in your environment, one of my colleagues, Marcel, has written up the steps here – https://ntnx.nl/marcel-kleinenutanix-com/red-hat-openshift-on-nutanix/. I recommend you check out this article and give it a try.

Final Word

You can architect and deploy a responsive, cost effective, and worry free enterprise environment, suitable for even the most critical apps, and deploy in minutes. You can deploy this environment wherever you choose, public cloud, in your datacenter, in a hosted environment. All while achieving consistent and predictable SLA’s. No need to compromise when you want agility, availability, and scale. RedHat OpenShift, Nutanix AOS and Nutanix AHV are a powerful combination for the next generation of apps to power your business.

If you have an application that needs very high service levels for availability (99.999%), 24/7/365, including maintenance and patching, then OS Clustering with shared storage is a proven solution. However it can be very complex to set up and maintain Fibre-channel, iSCSI or direct attached shared SCSI solutions. In some cases complex configurations are required not just in the hardware, but also the Operating System of the Guests. If you add in virtualization to the mix, the complexity level can increase more, with the need for physical mode raw device maps. Ironically, increased complexity can decrease overall availability, especially with an increase in the probability of human error. So how do we increase availability, decrease complexity, and provide a simple solution for OS Clustering with shared storage?

Nutanix AOS 5.17 with AHV has the answer. Nutanix AHV allows shared storage for Guest OS Clustering without any complex back end storage support or configuration, unlike other hypervisors from leading vendors, which still require Fibre-channel storage if you wish to use virtual disks. From Nutanix AOS 5.17 onwards you are able to configure a shared volume group and directly attach it to 2 or more VM’s and set up Guest Clustering without any complex in guest OS storage configuration at all. There is no complex storage back end, as that is all provided automatically by Nutanix AOS, and no in guest storage configuration, that might ordinarily be required if using iSCSI. This makes the use of Guest Clustering incredibly simple, as well as being very easy to automate, and significantly less difficult to support and troubleshoot.

The process for creating a Guest OS Cluster has 3 main steps:

  1. Create 2 or more VM’s with the OS of your choice
  2. Create a Volume Group with the number and size of virtual disks that you want for your clustered applications and attach it to the VM’s
  3. Configure the clustering software inside of your chosen OS and deploy the applications

Here is an example of how the Volume Group might look in the storage section of Prism for AHV:

While it’s possible to have up to 256 vDisks or Volumes within a Volume Group it is recommended to have 32 or less. If you need more Volumes you can create more Volume Groups.

When you attach a Volume Group to VM’s they will be listed in the Volume Group page within the Storage section of Nutanix Prism Element as follows:

If you wish to have a mixed virtual + physical cluster you can choose to enable external client access to the Volume Group. Any physical / external clients can then use iSCSI Initiator to connect to the clusters Target Data Services IP (DSIP) and mount the volumes.

In the example above I created a 4 node Windows 2016 Cluster, which will host SQL Server 2016 as the primary application. The VM’s are listed below, along with an AD Domain Controller:

After the Failover Cluster Manager components and tools are installed you can configure the Failover Cluster. Note: as part of the cluster creation a verification wizard is executed to ensure compliance with the strict rules needed to form a cluster, including shared storage tests for SCSI fencing and persistent reservations. The nodes in this case were displayed as follows within Failover Cluster Manager:

The next step is to install SQL Server on the cluster nodes and assign all the necessary dependent resources, which would look like the following:

I installed a second SQL Server instance in the same Failover Cluster so I could do comparisons between different configurations. You can see that in the image below:

After I created the cluster I did a series of tests including using tools such as HammerDB and Benchmark Factory for Databases. During the tests I performed live migrations to ensure the cluster didn’t blink in spite of the load, and it worked flawlessly.

Final Word

Nutanix AOS 5.17 and AHV makes creating guest clusters simple and quick and supports both Linux and Windows Guest OS types. You can now configure your fav clustering solutions without the traditional complexity and that means it’s way easier to automate. A Nutanix AHV cluster can now support any number of cluster nodes supported by the OS vendors. The next step in the evolution of this will be when AHV supports Metro Cluster across sites, along with volumes, which will allow for geo distributed guest clusters with greatly reduced complexity compared to the traditional implementations. The cluster example in this article with Windows 2016 and SQL Server 2016 was created just by following the standard Microsoft Documentation and directly attaching a Nutanix Volume Group on AHV directly to the 4 Windows VM’s that would form the cluster. That’s it, no special tuning or complexity needed.

HammerDB is a very popular benchmark tool for testing multiple different database engines, including Oracle, SQL Server and PostgreSQL. This is a brief article to bring your attention to some ways you may improve your results and get more valid benchmark data.

We do a lot of testing with HammerDB at Nutanix. We run multiple database engines through HammerDB for each release of software we release. One of the great things about running databases on Nutanix is that once you find out how much performance you get from a given configuration of a node or database, you can scale it linearly and get the same experience. This fact was demonstrated by a test that Gary Little (Performance Engineering at Nutanix) did some time ago and published in his article SuperScalin’: How I learned to stop worrying and love SQL Server on Nutanix – Recommended Reading. Over the years we’ve found some things when using HammerDB that can improve consistency and reliability of test results.

Sometimes SQL Server might only use a single NUMA node due to the way connections and transactions are assigned in the engine. Gary describes the problem and solution in his article SQL Server uses only one NUMA Node with HammerDB. The solution is a slight modification to how the HammerDB scripts execute.

Another issue we’ve frequently run into when testing large SQL Server databases that needs lots of cores and memory is that not all the cores get used. Often you might find only 20 CPU’s are being used by the SQL Engine, even though you are using Enterprise edition. This is due to the ISO and installer being used not being the Core Edition of SQL Server Enterprise. You need Core Edition to allow more than 20 CPU’s to be used by the database engine.

Another common issue that we have discovered and Gary has documented in his article HammerDB: Avoiding Bottlenecks In Client, is settings in the actual HammerDB client. Specifically around how the client logs data. Check out Gary’s article for the settings you should uncheck before running a test.

Other basic issues we’ve found is the system under test not being sized properly for SQL Server, or the VM’s running SQL Server not being properly aligned to the NUMA nodes and configurations of the hardware being tested. an 8 vCPU VM isn’t optimal if running on a 12 CPU socket, whereas a 6 vCPU VM would be better. We have found that right sizing the VM’s produces far better results. In this case, 8 vCPU’s might produce less transactions per minute and less new orders per minute and higher response times than if 6 vCPU’s was used. On an 18 core socket, 9 vCPU’s or 6 vCPU’s are also good options. Some people find it difficult to use an odd number of vCPU’s, but the scheduler works fine.

Final Word

Benchmarking SQL Server with HammerDB can help determine what performance you might reasonably expect from a platform running different types of databases and show how a platform scales, but it isn’t exactly the same as your real world workloads. The best way of determining how your workloads will perform is by testing them on a the platform with test cases you have valid comparisons for and under similar conditions. Always account for maintenance tasks, such as backups, stats update, reindex etc and allow headroom for growth. I hope the above help you and wish you all the best benchmarking with HammerDB.
