Storage Container Recommendation
Hi,New to Nutanix. Setting up our new Nutanix cluster that will run VMware as the hypervisor. Is it recommended to create 1 storage container that utilizes all storage capacity for all VMs (150) to reside? I am use to creating multiple datastores in a traditional 3 tier architecture, but i know a lot of those practices go away with hyperconverged.The main reason I ask is that although we have no plans at this point to use other Nutanix services such as Files or Database, I don’t want to be in a position if I create a storage container for VMware VM’s and assign it all of the capacity and then find out later that I cannot use Nutanix Files because all space was initially given to VMware.Any recommendations or best practices you can share to ensure I don’t shoot myself in the foot?Thanks

Don't Control the Network? No Problem. Nutanix Native DR Encryption to The Rescue
Stop the Man in the Middle Attacks.Whether you're replicating to the cloud or to a remote branch site you may not control the networking stack and to end. When you don't control the networking stack end to end or you're in an environment that simply doesn't have a firewall you can use Nutanix Native DR encryption between your Nutanix clusters. The feature is fully supported for both PD and Nutanix DR(PC) based replication.Changes will persistent after reboots of the CVMs and upon upgrades.AOS needs to be on 6.1 or higher.DR with Encryption will use 14119,14108 as additional ports that need to open bi-directional when all of the CVMS. *** Note you need to run the below steps on each cluster.To enable this featureSSH to the CVM Change the folder to bin - all the python commands need to ran from the bin directory cd bin Run the script. For PD based Replication python onwire_encryption_tool.py --enable <remote_cluster_vip> For PC/Nutanix DR Replication Enure your Prism Centrals
How to Size a new Nutanix cluster from VMWare to Nutanix
Hello All, I'm working with a customer on a new solution designthe customer has a VMware workload and we plan to put AHV,I want you to advise me on how I calculate the storage requirement, Let’s say the customer workload is about 170 TB how do i size the cluster storage Also, I have some questions related to storage sizesif I have 3 nodes clustereach node with 10 disks each disk 4 TB (numbers for examples only)that means total raw storage is 120 TBwe will go with RF2 which means 1 node is out of our usable capacity calculation So what is the usable capacity here after the 1 node for failure and the Raid used in the cluster creation, also what else should be conducted from the storage in storage planning?
Flow Gateway VM in Azure - Everything you need to know.
The Flow Gateway VM (FGW) for Nutanix Cloud Clusters In Azure(NC2) is the Lynch pin to having a your own Supercloud. The FGW is responsible for all VM traffic going north and south from the Nutanix cluster in Azure. This virtual machine allows outside communication from both cloud and on-premises services to the workloads running on the Azure NC2 Cluster. The Flow Gateway VM connecting Azure and on-prem services to the Nutanix Cluster deployed in Azure.Once Prism Central is automatically deployed from the cluster creation process, the FGW deploys into the same VNET that Prism Central is using. The FGW is a native Azure VM. The VM has two network interface cards(NICs) attached to it, one for internal traffic and one for external traffic. The external NIC where the floating IP's are configured for workloads that may need away outside clients connecting into running workloads on the cluster. The default installation will configure 50 floating IP's on the external NIC. These floating I
Azure Networking – Picking the right path.
One of the biggest changes with Nutanix Cloud Clusters (NC2) on Azure compared to it's AWS counterpart is the requirement for Flow virtual networking. Flow virtual networking provides an overlay in Azure to provide secure communication between multiple tenants you may be hosting on the Nutanix cluster and also provides north and southbound connectivity. North and southbound connectivity is provided through the Flow gateway virtual machine (FVGW). Workloads running on the cluster can either go through a network address translation (NAT) path or a routed path not using a NAT. Which path your virtual machines take in and out of the NC2 Cluster will depend on how other services need to talk to the running virtual machines on NC2.The FVGW Is a native Azure VM that gets deployed when the first cluster is created. The FVGM has both and internal and external network interface cards(NIC). Traffic from your Azure Nutanix cluster is directed towards the FVGM’s Internal NIC And then eventually rou
Managed Network across clusters
Hello All, I have added a managed network in our cluster. We have since purchased another cluster and in the process of configuring VXLan and the ability to live migrate VM’s between clusters. From what I have been seeing we cannot have a managed network across clusters is this correct? If not does anyone know how to configure a managed network to work between clusters.Thanks,Scott
NC2: Self healing is great but you still need to check the Cloud Portal
I would like to take full blame for people thinking self healing solves all problems with Nutanix Cloud Clusters (NC2). The self-healing is pretty awesome for bad nics, hard drives and nodes but there are some instances where the portal can’t take action.Status checks on AWS are performed every minute, returning a pass or a fail status in the Cloud Portal. If all checks pass, the overall status of the instance is OK. If one or more checks fail, the overall status is impaired.There are two types of status checks, system status checks, and instance status checks. System status checks monitor the AWS systems on which instance runs. Instance status checks monitor the software and network configuration of individual instances. Notification Center in the Clusters PortalThe Clusters portal has an notification service that keeps track of all informational, warnings and critical alerts. Like most Cloud based services there is no support for SNMP in the portal but does have the ability to send
Options for Autoscaling Your Nutanix Cluster in the Cloud
I had made a short video on auto scaling Nutanix cluster in AWS using new Nutanix Playbooks. Playbooks offer a visual way to start automating actions in your hybrid cloud. Due to making the video short, I didn't spend a lot of time talking about options that you could set. Prism central has a lot of alerts that you can use to trigger the action that you want to take. If you don't see the right “Alert” you can customize one of the existing ones to meet your needs and will be a user defined alert. In my example I was using a critical memory capacity over 80% capacity on adding nodes. If your clusters are typically higher than 10 nodes you might try using a higher percentage based on one node is going to be a lower percentage of memory overall. Likewise you could be more aggressive with picking a lower memory percentage. One thing that you'll want to set as well is the “trigger alert if condition persists for". I didn't have it set so I could easily record the demo but I think it would be
Nutanix Networking in Azure - hybridcloud
Nutanix’s support for bare-metal is getting close. Please take a look at some of the foundational components for networking in Azure.NCM (Nutanix Clusters on Azure) utilizes Flow Networking to create an overlay network in Azure to ease administration for Nutanix administrators and reduce networking constraints across Cloud vendors. Flow Networking is used to abstract the Azure native network by creating overlay virtual networks. On the one hand this abstracts the underlying network in Azure, while at the same time, it allows the network substrate (and its associated features and functionalities) to be consistent with the customer’s on-premise Nutanix deployments.You will be able to create new virtual networks (called Virtual Private Clouds or VPCs) within Nutanix, subnets in any address range, including those from the RFC1918 (private) address space and define DHCP, NAT, routing, and security policy right from the familiar Prism Central interface.Flow networking can mask or reduce Cl
Cascade Lake vs Ice Lake
So i’ve been going through Google searches to find an answer whether Cascade Lake vs Ice Lake can coexist within the same cluster. Unfortunately no luck. So i hope this forum can help me answer this question.My concern is that i was made to understand that Cascade Lake and Ice Lake CPU architecture is different, thus that may pose a performance problems to VM even if the nodes can coexist within the cluster.So the question is, can NX-G7 and NX-G8, which will run on different CPU archtiecture coexist within the same cluster and will it cause any performance issues if this is possible?It would help if you can point me to a KB article or any article for that matter to explain this.Thank you in advance for the help……..
Nutanix Data Protection to the Power of Public Cloud
Since its inception; the Nutanix platform has offered customers a robust set of data protection technologies. Many of our customers leverage these capabilities as a part of their DR strategy.Now, with the advent of Nutanix Clusters (on AWS bare metal today) extending the capabilities enabled by the data protection suite to the public cloud is now a reality. Nutanix Clusters on AWS deploys the Nutanix HCI stack onto AWS bare metal instances. Provisioned via a customer portal customers can have a public cloud resident Nutanix Cluster operational in very short order.At which point they’re ready to leverage the public cloud as a part of their DR strategy; while maintaining a familiar operator experience:
Elastic DR with AWS (X-play and Clusters Portal API)
I make no bones about it, bare-metal nodes in AWS is pricey. The questions becomes if we want to save money and have DR with AWS, how do keep the number of nodes small until we failover?In AWS all the Nutanix rules still apply. We need a minimum of a three-node cluster to get started. If we have enough storage capacity, we can keep accepting replications from an on-prem cluster and not worry about CPU and memory constraints. You could also use your on-prem AHV supported backup software to backup directly to S3. Then when you have an outage, you could quickly build a Nutanix Cluster in AWS and start restoring the data to that cluster.DR on the skinnyI was a asked to automate the process of adding nodes to a small Nutanix Cluster in AWS and then start a failover using Leap (DR runbooks) and X-play(automates actions based of events and alerts) in Prism Central (PC). The below video is what I came up with. The code to add a node via API from the Cluster portal is listed here:https://gith
