I have a customer who’s using the tool, but once she connects the tool the values of CPU and memory displays 0% of utilization. Can you help me to address this issue? 

Hi all!I’m looking for a HCL that details the exact firmware versions of specific components of a server to make sure that we are in the clear before we install or upgrade Nutanix.As far as I can tell there isn’t anyone to be found, at least not for someone who doesn’t have an account for the support portal (and I find it pretty odd to “hide” the HCL).I know there are HCL’s to be found outside of the support portal but those are extremely generic.Is there an HCL that is this detailed or is it only through trial and error we can figure out if we have the correct firmware?Thanks.

We have plan is to add e.g 10 new HPE Proliant DX380 12LFF server with the latest AOS, eg 5.17.1 into the existing cluster. Then remove 10 existing nodes and reimage and add it back. Can 5.10.5 coexisting with 5.17.1 in the same cluster? Thanks 

I'd like to just confirm, is there any Nutanix web page that lists the supported browsers?The support page below that I bookmark is already deleted.https://portal.nutanix.com/#/page/docs/details?targetId=Portal-Help:sup-browsers-requirements-sp-r.htmlSo I searched similar page in Support portal, but I couldn't find.I know the browser requirements is not necessary information for many people nowadays. However that page is useful for us, so I want to refer substitute one if exist.

Are you still wondering about the following questions?To Which Version of AOS should I upgrade to from my current version? Will it be 1-Click Upgrade or not? What are the EOL versions for AOS, Nutanix Files or Prism Central? What is my software compatibility?Answer to above queries and many other queries is one single Link i.e. Upgrade PathsHere are some snapshots from Tools:Image 1 Image 2Image 3 

Nutanix appliances support monitoring via SNMP. Only SNMP v2c and v3 versions are supported. SNMP v2c is supported starting with AOS 5.5. In addition, SNMP v2c with Nutanix does not support SNMP GET operations.The MD5 authentication is no longer supported in AOS 4.1 and later. SNMP can be set up using the Prism Web Console or from the nCLI. Setting up SNMP through nCLI Run the following command on any CVM (Controller VM) to add an SNMP user (encapsulate the keys in single and not double quotes). nutanix@cvm$ ncli snmp add-user username=SNMPUser auth-type=sha auth-key='SHAAuthKeyExample' priv-type=AES priv-key='AESPrivKeyExample'    User Name                 : SNMPUser    Auth Key                  : SHAAuthKeyExample    Auth Type                 : sha    Priv Key                  : AESPrivKeyExample    Priv Type                 : AES Privacy protocol settings are optional. You can create the user only with the authentication protocol: nutanix@cvm$ nc

There are times when working with your environment that one of the Linux guest servers will go unresponsive. Nutanix Support may ask for crash dump files from the Linux VM to further analyze the cause.One such method is to use “sysrq”. This utility found on the Linux Guest OS allows access to several essential kernel commands and allow Nutanix Support to take a more holistic approach in trying to find a root cause.NOTE: If the VM is hung/inaccessible and "sysrq" has not already been activated, you may not be able to generate a core dump with the following method. You can configure the "sysrq" when VM is up and running and wait for the future occurrence.For more information on how to activate this feature, take a look at the KB 9066 on the Support Portal

This article provides quick links required for troubleshooting the alert – “Invalid Network Mapping Specified” for your Nutanix cluster.

Hello, Regarding to this question https://next.nutanix.com/how-it-works-22/disk-fault-tollerance-8822, What will happen to VMs in a cluster with RF2 when 1 drive failed on 2 different hosts? Will be any data loss or no? Will VMs reboot?Thanks!

Hello all, i have a 3 node nutanix cluster and i was trying to deploy ACI for lab usage on nutanix AHV as a vm but while i launch the vm it wouldn’t accept my keyboard. please any idea how to solve.

If I update update firmwares or softwares via LCM, is LCM update out-of-band? Or in-band? I can’t find any information in TN-2122 (Life Cycle Manager).

Hello Guys, We´re currently trying to install a Big IP LTM image on Nutanix using acropolis however it´s not working... it seems we´re missing something. We´ve found a link in regards of this topic but we are receiving a message infoming we have no access to it. Does anyone know how we should proceed in order to install a F5 VE on Nutanix using acropolis? https://next.nutanix.com/archive-44/how-to-install-f5-big-ip-on-nutanix-ahv-8062# (not authorized to access) Thanks in advance!

I posted this earlier in the wrong forum. (Sorry about that. I’m a newb.) I am reposing here. I cannot seem to find the the performance stats in the v3 API that are available by default in the v2 get APIs for vms, clusters, hosts, etc.? Are the performance stats available in v3? If so does anyone know the endpoints. I’ve searched but cannot find them. I suspect v2 is going to be supported for quite a while so I can just use v2 but didn’t what to rule out v3 until I had a good reason to.

 Hello. I have a question about the RF2 function.Currently, it is composed of 4 nodes and RF2 as a cluster.As far as I know, RF2 has 1 node fail.If so, shouldn't the Data Resiliency Status drop to Fail?However, although one node has failed, the Data Resiliency Status is still OK.In fact, the CPU, Memory, and Storage usage in the current cluster is low.Currently only 3 nodes are active CPU is 20% Memory is 40% Storage is 18.5%.Why is the Data Resiliency Status Ok?Is there any problem with the service even if one more node is currently turned off?Or will the cluster die if 1 more Node dies?If you don't die, I want to know why.

Hi.  Prism -> Data Protection -> EventGroups of Async DR run backups only once every Dawn.However, if check the event, I will see several messages per group.If there is a ‘Search’ group, several messages are generated for the 'Search' snapshot in the event.Each has a different time.(AM and PM). How can you explain this process? Thank you.

I have a 3 node AHV cluster that uses 2x200GB SSD + 2x6GB HDD disks for each node. Would it be possible to add nodes to this cluster that uses 2x480GB SSD + 2x6GB HDD disks?Option is to first upgrade the 200GB SSD disks to 480GB to align all nodes to the same hardware. Maybe there is some gain in that?

Storage ContainersA storage container is a subset of available storage within a storage pool (see Creating a Storage Container). Storage containers are created within a storage pool to hold virtual disks (vDisks) used by virtual machines.CompressionYou can enable compression on a storage container. Compression can save physical storage space and improve I/O bandwidth and memory usage—which may have a positive impact on overall system performance.Inline compression will compress sequential streams of data or large I/O sizes (>64K) when written to the Extent Store (SSD + HDD).Offline compression will initially write the data as normal (in an un-compressed state) and then leverage the Curator framework to compress the data cluster wide. Below diagram explains how inline compression interacts with the DSF write I/O path:DeduplicationDeduplication reduces space usage by consolidating duplicate data blocks on Nutanix storage. You can enable either cache deduplication only or both cache an

Executive SummaryThis document makes recommendations for designing, optimizing, and scaling Microsoft SQL Server deployments on the Nutanix enterprise cloud. Historically, it has been a challenge to virtualize SQL Server because of the high cost of traditional virtualization stacks and the impact that a SAN-based architecture can have on performance. Businesses and their IT departments have constantly fought to balance cost, operational simplicity, and consistent predictable performance.Nutanix removes many of these challenges and makes virtualizing a business-critical application such as SQL Server much easier. The Nutanix distributed storage fabric is a software-defined solution that provides all the features one typically expects in an enterprise SAN, without a SAN’s physical limitations and bottlenecks. SQL Server particularly benefits from the following storage features: Localized I/O and the use of flash for index and key database files to lower operation latency. A highly dist
