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. Efficient one-click operations and self-healing security models easily enable automation to maintain security in an always-on hyperconverged solution.Since traditional manual configuration and checks cannot keep up with the ever-growing list of security requirements, Nutanix conforms to RHEL 7 Security Technical Implementation Guides (STIGs) that use machine-readable code to automate compliance against rigorous common standards. With Nutanix Security Configuration Management Automation (SCMA), you can quickly and continu

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.

I am moving virtual machines with Move 3.6.2 from Hyper-V to an AHV CE cluster. Everything goes well, but after the cutover the AHV VM is stuck at the ‘Press F2 for EFI boot manager’ screen and cpu usage around 52%. Pressing FN+F2, F2, CTRL+F2, ALT+F2 or other combinations have no effect. Please advise. Hyper-V host is Win2019, VM is 2019 with boot from bootmgfw.efi and secure boot disabled. Also tried with Edge, Chrome and IE, same result, stuck at ‘Press F2 for EFI boot manager’ screen.
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

LCM (Life Cycle Manager) is a tool provided by Nutanix to upgrade firmware and software across a Nutanix environment. Depending upon the type of firmware that needs to be upgraded, a reboot of a node may be required.While reviewing the inventory of software/firmware that needs to be upgraded, you may not know which upgrades require a reboot of a node (or not). This information might be crucial in determining the impact and precautions that need to be taken in planning for the upgrade event (change windows, time allocated, etc.).KB 6107 details which upgrades require a node or CVM reboot and which ones do not.

Many users are unaware that there are additional (beyond what is presented via the Prism user-interface) security parameters that can be employed on AHV hosts to increase the overall security of them. These security parameters are configured via Nutanix Command-Line Interface (NCLI) and include the following: Advanced Intrusion Detection Environment (AIDE) - a file and directory integrity checker High Strength Password Enforcement - configure the maximum and minimum number of characters the password must contain along with number of passwords retained in history to prevent repeated use Core Dumps - the recorded state of the working memory for a process is dumped to a file if the process ever crashes Login Banner - display a customized messages when user login to a node More information regarding these parameters, including the procedures to enable/disable them, can be found within the Hardening AHV section of the Nutanix Security Guide. Also to note, there are similar parameters
SAP helps customers migrate from traditional relational databases to their in-memory SAP HANA database to gain more agility in their business processes. Many SAP customers are searching for ways to deploy SAP HANA in an efficient, simple way that minimizes risk while preserving the benefits of an agile platform. Nutanix provides such an option. The native Nutanix hypervisor, AHV, and Nutanix enterprise cloud OS software are certified for production SAP HANA deployments. HCI for SAP HANA CertificationThe certification has two primary segments. 1. As the first step, a platform vendor (Nutanix, in this case) must validate their platform, which consists of a hypervisor and an HCI component.2. In a second step, the hardware OEM must certify a suggested configuration through some additional HCI-related tests. When both parts of the validation are complete, the solution is certified and listed in the HCI for SAP HANA category on the SAP website. The hardware OEM is then responsible for selli
Any modern environments consist of multiple layers each of which contains multiple components. There are switches and routers, firewalls, physical server, application servers, applications themselves and, of course, users. Each of the components has logs of more than one kind, location and severity. All the components interact with each other directly or indirectly. I am certain you have found yourself in a situation where to establish a root cause you had to inspect logs of more than one entity. Establishing a timeline of events is always easier when the sources of the events’ clocks are synchronised and are located in one central location. While the clocks are handled by the NTP the centralised logs location is a syslog server or in this case a remote syslog server implying that it is separate to the origination of the logs. In addition to the benefits already mentioned, remote syslog server allows to access logs for the systems that are already dead, decommissioned or replaced. Nuta
These days I’m managing, for one of customer, the migration of its virtual infrastructure to a Nutanix AHV farm from an old ESXi. It has some old VMs, with Windows XP as guest OS, that have to be migrated in Nutanix. Those VMs have installed custom software that cannot be installed in newer versions of Windows because they have been written in old VB6, so my question are:Can they be migrated over AHV? If yes, can I manage the migration with Nutanix Move or there is another way?
Use the Data Services IP method for external host connectivity to VGs. For backward compatibility, you can upgrade existing environments non disruptively and continue to use MPIO for load balancing and path resiliency. For security, use at least one-way CHAP. Leave ADS enabled. (Enabled is the default setting.) Use multiple disks rather than a single large disk for an application. Consider using a minimum of one disk per Nutanix node to distribute the workload across all nodes in a cluster. Multiple disks per Nutanix node may also improve an application’s performance. For performance-intensive environments, we recommend using between four and eight disks per CVM for a given workload. Use dedicated network interfaces for iSCSI traffic in your hosts. Place hosts that use Nutanix Volumes on the same subnet as the iSCSI data services IP. Use a single subnet (broadcast domain) for iSCSI traffic. Avoid routing between the client initiators and CVM targets. Receive-side sca

In many ways, identifying the problem is harder than solving it. At least in IT.In order to better understand the performance of Nodes in a cluster and User VMs, ESXTOP for ESXi hypervisors and TOP for Linux OS based machines provide us an immediate birds eye view of the performance of the host. It is important to understand the output as a tool towards problem-solving. Here I aim to discuss scenarios you might need to isolate and troubleshoot High CPU observed at the Hypervisor or User VMs.ESXTOP : This command when run lists live CPU statistics specific to the Node the command is run on.esxtop outputIf you press “M” it shows you memory metric and “N” for network etc. As Always ‘H’ is for help. We will focus on a few CPU statistics:The output will show you all the VMs and the following metrics corresponding to them.Some Important ones discussed below:%USED, %RDY, %CSTP , %MLMTD and %SWPWT Note:To convert CPU ready % value to ms(milliseconds)CPU ready % = ((CPU summation ready value i
PCI device enumeration is one of a large number of concepts that transitioned from the physical world. Originally, being a bus and a slot number now, of course, is a virtualised concept.When OS boots during the POST process the local devices are enumerated (checked for presence and size). If an expected device is found at the PCI slot that is a failure of the test. In AHV deployments, the Controller VM (CVM) runs as a VM and disks are presented using PCI passthrough. That means that if AHV PCI devices enumeration has changed CVM may not be aware of the fact and attempt to direct I/O to the devices that are no longer accessible via known PCI bus and slot. This can happen after hardware replacement on an AHV host and the CVM will not boot or will boot with only part of the expected devices accessible. Compare PCI slot numbers of SCSI controllers on AHV host and the CVM and update the enumeration of the devices on the CVM. For more details look at KB-7154 AHV | CVM might not boot after ha

Nutanix Objects OverviewNutanix Objects™ (Objects) is a software-defined Object Store Service. This service is designed with an Amazon Web Services Simple Storage Service (AWS S3) compatible REST API interface capable of handling petabytes of unstructured and machine-generated data. Objects addresses storage-related use cases for backup, and long-term retention and data storage for your cloud-native applications by using standard S3 APIs. You no longer have to introduce an external, separately managed storage solution. Objects is deployed and managed as part of the Nutanix Enterprise Cloud OS.You can manage objects by using Prism Central or the S3-compatible REST APIs after an administrator has authorized the applications and users to access buckets accordingly.For more information on Objects architecture, refer to Nutanix Bible.Usage of ObjectsFollowing are examples of solutions you can implement by using Objects: Backup – You can integrate Objects with the backup applications such as
The cloud connect feature enables you to back up and restore copies of virtual machines and files to and from an on-premise cluster and a Nutanix Controller VM located on the Amazon Web Service (AWS) or Microsoft Azure cloud. When a new cloud remote site is created, Nutanix will automatically spin up a single node Nutanix cluster in EC2 (currently m1.xlarge) or Azure Virtual Machines (currently D3) to be used as the endpoint.The Cloud Connect feature enables you to back up and restore copies of virtual machines and files to and from an on-prem cluster and a Nutanix Controller VM on the Amazon Web Service (AWS) or Microsoft Azure cloud. The Nutanix Controller VM is created on an AWS or Azure cloud in a geographical region of your choice. It is a single-node cluster with a 30 terabyte (TB) disk attached to the node, with a usable disk capacity of 20 TB.The following figure shows a logical representation of a “remote site” used for Cloud Connect: Since a cloud based remote site is similar

Protection Domain–Based Data Protection is configured using Prism Element. Nutanix supports several types of protection strategies including one-to-one or one-to-many replication. These strategies are as follows:Per-VM Backup. The ability to designate certain VMs for backup to a different site is particularly useful in branch office environments. Typically, only a subset of VMs running in a branch location require regular back up to a central site. Such per-VM level of granularity, however, is not possible when replication is built on traditional storage arrays. In these legacy environments replication is performed at a coarse grain level, entire LUNs or volumes, making it difficult to manage replication across multiple sites. Selective Bi-directional Replication. In addition to replicating selected VMs, a flexible replication solution must also accommodate a variety of enterprise topologies. It is no longer sufficient to simply replicate VMs from one active site to a designated passiv
