How It works

In this Google-ready culture, many users will immediately turn to an internet search engine when seeking for information regarding a specific question or issue involving Prism. However, many users are unaware that Prism maintains an online help system which responds-to and changes depending upon which dashboard is currently being viewed within Prism.For example, a user may be interested in deploying a File Server and may have questions regarding this while reviewing the File Server dashboard within Prism. From that dashboard, simply clicking the global question mark icon from the top menu and selecting the “Help with this page” option will automatically open a new browser tab to the File Server Management section of the Prism Web Console Guide. What’s more, the specific version of the Prism Web Console Guide that is displayed corresponds to the current version of Prism from which it was launched.Further, some of the dialogue boxes within Prism also contain a question mark icon which wi

Hi,First time attempting to install Nutanix. I’m experienced with VMWare, but I wanted to try out Nutanix, mainly as I read it will allow me to create a single-node cluster, using locally attached NVMe disks without the overhead (headache) of vSAN (that doesn’t work as a single-node).Running through the installer, I see I have to specify an AHV (equivalent of ESX?) boot disk and CVM boot disk that requires a disk of at least 200GB. If I understand correctly, CVM is the equivalent of vCentre Server (VCSA).Firstly, can I install this CVM somewhere else?Secondly, I don’t have a separate disk of >=200GB that I want to waste on CVM. I have a 128GB SSD that I would have used for data, but the installer won’t let me and I can’t use it for CVM either because it’s too small. If I can’t farm off the CVM to another device, is there a way to override this limitation? Even fat old VCSA only uses 72GB across its 13 disks. What is in CVM! These are my disks. As you can see, to install CVM on its o

Does anyone knows size of VM’s snapshot file? I am concern about disk space, but I also need to back up. Is there formula for calculate snapshot file size approximately?   

Hi! I've got several questions about the usage of v2 API which I have not been able to solve by myself after looking a little while.on some endpoints, for example, GET /alerts, GET /vms and a few more things are functioning for me as expected, but on other endpoints, such as POST /vms/{uuid}/set_power_state I am receiving the following response:{ "message": "Access is denied", "detailed_message": null, "error_code": { "code": 1100, "help_url": "http://my.nutanix.com" }}any idea what's causing it? I've been searching for detailed information on your error code (such as 1100 listed above) and couldn’t find. Is there any documentation to the error codes that  you can send me a link to?Also, in a few of the API endpoints I couldn’t understand exactly what is the expected query parameter to be sent.2 examples of endpoints I felt I am lacking knowledge what exactly meant to be sentGET /vms filter: Filter criteria - semicolon for AND, comma for OR. where can I find what counts as fi

Switch engineer changed vlan (vlan id). Is it possibly auto update in nutanix arp table? if not, what kind of command require to do? 

Network visualization Is one of those underrated but extremely useful features. Network visualization is a consolidated graphical representation of the network formed by the VMs and hosts in a Nutanix cluster and first-hop switches. Nutanix network visualization allows you to group VMs by power state or by parent hosts, group hosts by parent clusters or select a particular node from the cluster. Choose your layout based on the current needs.   In Nutanix network visualization, every entity is interactive. For example, when you click on a VM you can see detailed information about its vNICs such as MAC address, IP address, VLAN ID, live statistics.   Similarly, switch port will show information about MAC address, MTU size, live statistics.     To enable Network visualization a set of requirements must be met: Configure SNMP v3 or SNMP v2c on TOR switches Enable LLDP or CDP on the first-hop switches. Network connectivity over SNMP port between CVMs and switch management IP addres

In some cases, you might have to permanently remove a physical node / host from a Nutanix cluster. There are two scenarios in node removal. Permanently Removing an online node Removing an offline / not-responsive node in a 4-node cluster, at least 30% free space must be available to avoid filling any disk beyond 95%. You cannot remove nodes from a 3-node cluster because a minimum of three Zeus nodes are required. Some Points to consider before initiating node removal: Sufficient Disk space available on other nodes in the cluster User Virtual Machine relocation (if required) Any software upgrade should not be running Checklist on verifying cluster health status Data resiliency is “OK” (green) in Prism Run a complete “ncc report” either from prism or CVM cli:                                 ncc health_checks run_all Depending on the size of data, node removal can be lengthy process, which involves relocating data from the node to other healthy nodes in the cluster.

What is happening to my 2 node cluster during a failover or an upgrade?What does a recovery process look like after a node failure?If you are wondering the above, we have the answer for you! You can monitor the progress of your 2 node cluster in these situations through Prism Element.To monitor node recovery progress after failover: Registering a witness is highly recommended to help the cluster handle the failover situation automatically and gracefully.  Stand-Alone mode: A failed node would trigger cluster to transition into stand-alone mode during which the following occurs: Failed node is detached from metadata ring. Auto rebuild is in progress. Surviving node continues to serve the data. Heartbeat: Surviving node continuously pings its peer. As soon as it gets a successful reply from its peer, clock starts to ensure that the pings are continuous for the next 15 minutes. If a ping fails after a successful ping, the timer will be reset.  Prism Element Home page shows Critical

Prism Central includes machine-learning capabilities that analyze resource usage over time and provide tools to monitor resource consumption, identify abnormal behavior, and guide resource planning. These tools include VM "right sizing" where VMs are analyzed and those that exhibit inefficient profiles are identified. Anomaly detection to record when performance or resource usage is outside an expected range based on learned VM baseline behavior. "Smart" alerts that trigger when specified anomalies are recorded. Reports that summarize cluster efficiency. VM Right SizingIt is useful to look at the profile of your VMs when analyzing problems in a cluster or assessing future resource needs. This can help you identify VMs that are not optimally configured such as ones that consume too many resources, are constrained, are over provisioned, or are inactive.Anomaly Detection:The right sizing feature identifies inefficient VMs that fit one of the profiles described as below: Bully VM : A

Nutanix takes a holistic approach to security with a secure platform, extensive automation, and a robust partner ecosystem. The Nutanix security development life cycle (SecDL) integrates security into every step of product development, rather than applying it as an afterthought. The SecDL is a foundational part of product design. The strong pervasive culture and processes built around security harden the Enterprise Cloud Platform and eliminate zero-day vulnerabilities.

Here I discuss the effects of Enabling or Disabling Deduplication on a container even if the Container has data already written to it. The benefit of Compression and Fingerprinting+Deduplication is to hold more data in the container, by reducing the stored size and avoiding duplicate data, respectively.Nutanix’s intelligent selection of dedupable candidates prevents deduplication being performed where the benefit would be low. Deduplication Best Practices: Enable deduplication Do not enable deduplication Full clones Physical-to-virtual (P2V) migration Persistent desktops Linked clones or Nutanix VAAI clones: Duplicate data is managed efficiently by DSF so deduplication has no additional benefit Server workloads: Redundant data is minimal so may not see significant benefit from deduplication  Enabling Dedupe:Fingerprinting is method of creating signatures of the data in Metadata.

Have you guys been utilizing the Analysis charts feature effectively? It gives you the ability to create charts that can monitor a variety of performance metrics over a week, month, or a custom time range.  Here are a few ideas on how we resolved some issues seen in the field.  Memory Usage (%) - Create a chart to track memory consumption or one or multiple VM’s over a time interval   Hypervisor CPU Usage (%) - Measure the CPU usage of one or more hosts over time and gain a better understanding of resource constraints if any   Storage Controller Latency - This is particularly useful if you suspect performance issues. Creating charts ranging to a few weeks back gives you a comparative analysis and a benchmark for the current latency observed   Storage Container Usage - A classic use case for this is when multiple VM’s have been migrated out of the cluster over many days but you suspect the storage space has not been reclaimed   Replication Bandwidth - Transmitted - If there are
