5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Maintaining a big infrastructure requires planning and knowing your architecture inside and out.Let's say, sometimes you need to check the upgrade history of different components in your cluster.Sometimes you want to know when you last upgraded AOS or Nutanix Files.The timestamp of the upgrade.Let's say you want to plan a future upgrade and creating a time-line and want to know when you upgraded the software last and at which version.We all need this information, either to maintain a proper record of our cluster infrastructure or to plan the future upgrade.So how can we achieve this?Give the following Knowledge base article a read to find out the upgrade history of different components in your cluster and plan your future upgrades accordingly.KB-1151 Want to know how upgrades work in Nutanix? Try going through the following Knowledge Base to understand how upgrades work in Nutanix architecture.KB-6945 Have a question regarding upgrade workflow? Drop a comment and let’s start a conversa
Ever been in a situation where you forgot the password to your laptop, email account or your smartphone. Imagine the same when you’re an administrator and managing large scale environments. What will happen if you forgot the password to Prism Web Login? You can’t even run the ncli commands! Do we have a mechanism through which we can recover the password of the prism web console? What can we do if we have forgotten the password and want to reset it to default? Do we have a guide for that? Of course. Just follow the steps mentioned in the document below to reset the prism web console password! Reset nCLI or Prism Web Console Password
SIOC or Storage I/O Control is a feature in ESXi which when enabled, it helps the ESXi to monitor datastore latency and throttles the I/O load if the datastore average latency exceeds a particular threshold. So what is esx_sioc_status_check ? The NCC health check esx_sioc_status_check verifies if the vSphere feature "Storage I/O Control" (SIOC) settings for both "SIOC" and "SIOC in Stats Mode" are disabled on Nutanix containers. Why do we want SIOC setting to be disabled in the cluster? SIOC is an excellent feature for traditional server infrastructure, but it is neither required nor compatible with the Nutanix converged storage architecture. Starting from ESXi 6.0, SIOC in Stats Mode is enabled by default. Nutanix requires that both features be disabled. It can cause a range of problems in a Nutanix environment and it's highly recommended that we disable it Want to know more about the issues caused by enabling SIOC and a step-by-step guide as to how to disable it.

Managing a large infrastructure is a tough and complex job. If you have 10+ clusters in your environment with thousands of virtual machines, managing the architecture becomes a whole lot easier with Prism Central. Let’s consider a scenario where you decide to go ahead with a Prism Central deployment but to achieve the best performance, Prism Central VM must be sized to fit the environment. Currently, confused regarding the optimal memory, CPU and storage configuration of PCVM? What should be the configuration in a single or scale-out deployment? The following document lists the details related to Prism central scalability. The configuration of PC VM depends upon the number of UVMs in your environment. Prism Central Scalability Document Have questions or doubts regarding Prism central? Drop a comment and let us start a conversation.
Nutanix guest tools (NGT) is a software bundle that you can install in a guest virtual machine (Microsoft Windows or Linux) to enable the advanced functionality provided by Nutanix. Nutanix Guest Tools enables the VM to CVM communication and sometimes we might encounter the NGT Services to be falling with the signature guiding towards SSL error. So how do I identify if I’m facing a similar issue and resolve it? You can refer to the KB-3868 for guidance regarding which log file to check and which error trace is matching the issue. After confirming that you’re encountering the same issue, you can proceed with the solution mentioned in the knowledge base article. Want to know more about NGT and it’s configuration?

Data is everything in this modern IT world and we want to have as much storage capacity as possible in our infrastructure. Let’s say you have a new Nutanix cluster and want to know the recommended maximum storage utilisation capacity of the cluster. NOTE :- We should not try to utilise the cluster to it’s peak storage as we need to have sufficient space available in case a node or a disk fails to rebuild the data. Whenever a disk fails in a Nutanix cluster, the extent groups of that disk needs to copied to another disk to ensure fault tolerance, same goes for a node failure.So how can we calculate the maximum storage utilisation of our cluster and if different scenarios, if we have RF-3 or if we have RF-2? Please go through the KB-1557 to understand the formula to calculate the maximum recommended usage for a cluster.
Let’s say you are managing an Infrastructure and have a range of networks defined in your environment and now you have to delete a few.You go to Prism, try deleting the network but get a generic error.So what’s going wrong here?Why can’t you delete a network?Well, one possibility is that if there are NIC connected to the network, it won’t let you delete the network, kind of like a guard-rail.So what can you do to mitigate it?Try giving the following KB a read KB-8234 Want to know more about AHV Networking?
