Installing F5 Big IP VE using Acropolis

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!

where are the performance "stats" in the v3 api

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.

How many node fail can you withstand?(4Node Cluster - RF2)

 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.

Expand Hybrid cluster with nodes that has different disk sizes

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 Components

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

Designing, Optimizing and Scaling Microsoft SQL Server

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

Nutanix Move v3.6.0 CentOS 8.2 support

Looking on OS supported to migrate with Nutanix Move v3.6.0 I see CentOS 8.2 as supported but when I add a CentOS 8.2.2004 VM to be migrated from ESXi 6.7u2 to AHV 20170830.434 I get this warning:This VM is not on the AHV supported OS list. To proceed with migrating this VM, please be sure to bypass guest operations and take care of installing AHV device drivers separately. This VM has a guest OS which is not supported on ESXi. Please remove the vm from the migration plan if migrating to ESXi.Is this expected?

Segmenting Network Traffic

Many users are unaware that network traffic can be segmented (or separated) within a Nutanix cluster for various functions or purposes. For example, backplane traffic can be separated from Management-Plane Traffic so as to allow for even greater available bandwidth for the backplane traffic. Further, as another example, DMZ related traffic could be isolated to specific host uplinks. The four primary means of network segmentation are the following:Isolating Backplane Traffic by using VLANs (Logical Segmentation) Isolating Backplane Traffic Physically (Physical Segmentation) Isolating Service-Specific Traffic Isolating Stargate-to-Stargate traffic over RDMATo note, certain means of segmentation are limited to certain hypervisor versions. For example, the segmentation of management and backplane traffic is supported across the AHV, ESX and Hyper-V (Hyper-V offering logical segmentation only) hypervisors, while service-specific segmentation is supported only by the AHV and ESX hypervisors.

VirtIO Driver Versions for Windows

Nutanix VirtIO includes device drivers specifically used by Windows VMs hosted in the Nutanix environment to enhance their stability and performance. This concept is very similar to VMware Tools for ESXi environments.The VirtIO bundles various drivers including:Balloon Driver Ethernet Adapter RNG Device SCSI pass-through controller Serial Driver SCSI ControllerThe VirtIO package is found on the Support Portal under AHV (please select “VirtIO” from the corresponding drop-down menu).To note, the device driver versions contained within the various available Nutanix VirtIO packages may be the same if there have been no updates for the drivers between the package releases. To correlate the driver versions associated with each VirtIO package release, please reference KB 5491 in the Support Portal.Further to note, beginning with VirtIO package release version 1.1.6 all driver versions match the VirtIO package version.

Consistent bridge configuration required on AHV hosts

AHV hosts in cluster running AOS 5.18 or newer may become non-schedulable if bridge configuration across cluster nodes is not consistent. What is a non-schedulable node?A non-schedulable node is used to increase data storage on your Nutanix cluster and does not run any guest VMs on that node.To check if this situation exists on your cluster and to fix the issue, check KB-10217.

Bridges With Single Uplink

Nutanix AHV uses Open vSwitch(OVS) to connect to the CVM, the hypervisor and the user VMs to each other and to the physical network on each node. The CVM manages the OVS inside the AHV host. Since the OVS is an open source software switch that behaves like a layer-2 learning switch, it maintains a MAC address table. Each AHV server maintains an OVS instance, managed as a single logical switch through Prism. Bonds:When multiple uplinks are used they are added to a bond acting as a single logical interface, to which the bridge is connected. Open vSwitch (OVS) does not support bonds with single uplink and as workaround we directly connect bridge to single uplink.WARNING:Avoid the use of a single uplink configuration and do not attempt to modify a single uplink configuration using manage_ovs if the version of AOS is 5.10.x prior to 5.10.4. Warning:Updating uplinks can cause short network disconnect. It is strongly recommended performing network changes on a single node at the time after ma

Upgrading VMWare

Hi there.  I’m trying to plan an upgrade on our nutanix clusters from VMWare 6.5 to either 6.7 or 7.0 and I’m having a bit of a struggle figuring out the compatibility of the different VMWare versions along with our Nutanix clusters. We have two Nutanix clusters, our main site is a 7-node cluster with 5 Gen5 nodes and 2 Gen7 nodes.  Our remote data center is a 6 node cluster with all Gen 6 hardware.Our main site is running AOS 5.10.5 LTS and our remote datacenter was just recently upgraded to 5.15.2 LTS in preparation for the vmware upgrade.  I plan on upgrading our main site to the same AOS version of 5.15.2 LTS.Where I have an issue is that when running the VMWare Assessment Tool (VSAT) I keep seeing notifications on each cluster that certain nodes may not be compatible with VMWare 6.7 or 7.0 because of various devices that “May not be supported” yet say things like “is certified but current driver (ixgbe) is not supported”.  In some cases the same exact nodes in the same cluster wit

Prism Central RBAC assignments

Hello All,I have recently deployed Prism Central and I am trying to give team members access via their AD accounts. I have went through the roles and discovered I cannot add new members to the predefined roles; however, if I duplicate the roles I can add AD users and groups to the new roles. This works for me however when I duplicate a role such as the “Super Admin” role I am warned that not all permissions are going to apply to the new role and I would need to create the new role via CLI to get these permissions. Ok fine that makes some sense. But where is the documentation on how to do that? Can someone point me to the documentation to perform these role creation tasks via CLI?Thanks, Scott
