AHV Virtualization

Hi Does anyone having experience or recommendation for tuning Postgresql Server Workload on Nutanix? We followed the Nutanix SQL Server Best Practices and Micheal Webster's Recommandations for vDisk and LVM layout at: http://longwhiteclouds.com/2014/11/27/performance-testing-mysql-and-postgresql-with-hammerdb-and-pgbench/ Unfortunately, the Performance does not meet our expactation compared to our old PostgreSQL server running on a NetApp Filer. Out Setup: 3 Nodes Nutanix Cluster NX-6035-G4 with 1200 GB SSD, NOS 4.6.11 vSphere 6

Running DELL XC630 5 node cluster with ESXi 6.0 / NSX Trying to use One Click Upgrade to move from NOS 4.5.2 to 4.6.2 PreUpgrade Check fails with "Failed to connect to Hypervisor managment IP X.X.X.1 Failed to connect to Hypervisor managment IP X.X.X.2 Failed to connect to Hypervisor managment IP X.X.X.3 Failed to connect to Hypervisor managment IP X.X.X.5" x.x.x.1~5 being ESXi IP External addresses - SSH to all ESXi from all CVM on both Internal and External IP works. (also the reverse connection is working) - ESXi reboot / Genesis restart done - fix_host_ssh done - even updated all ESXi root password on CVM (even though unchanged just to be sure) - No Alert/Warning under PRISM - ncc health_checks run_all came out with flying colors. - Identical setup at DR site having same issue/symptoms tail -f genesis.out shows: esx_utils.py:135 Connection to host x.x.x.1 failed x.x.x.1:443 is not a VIM server host_upgrade_helper.py:655 Error in connecting to local hypervisor Stumped and he

Apart from listed pre-requisites before starting Hypervisor Upgrade (ESXi) listed below, had to Disable Affinity Rules under DRS to enable ESXi host go into Maintainance mode and continue update. Got stuck since i did found this part the hard way... 1) Genesis.out log pointed the target CVM owning Shutdown token and not letting it go. 2) Then from vCenter: Manual Shutdown of CVM -> Manually put related ESXi host in Maintainance mode -> Exit Maintainance mode -> Start CVM 3) Go to PRIMS and upgrade continues... and so does 2048... - Koji

There appears to me a Management Pack for SCOM 2012 available now http://myvirtualcloud.net/?p=6687 but I cannot find it. Can anyone pls help? Thx, John Bradshaw

Good day, Quick question regarding Exchange on Hyper-V, I havn't been able to iron out all the questions regarding the support for Exchange on Hyper-V where the .VHDX files resides on the backed SMB3 part. From a Microsoft stand-point they support .VHDX files on SMB3 as long as it's backed by block storage, but I havn't been able to verify that Nutanix actually goes under the "Block-Storage" part, on my own mind it should. There are a few documents where Exchange on Hyper-V is mentioned, and in those SMB3 and iSCSI are both mentioned but no on what part (SMB3 for OS, iSCSI for Databases or in fact VHDX on SMB3 for databases also). VMWare is rather straight forward, Volume Groups to be fully supported by Microsoft, period. But what is the stand-point regarding Exchange on Hyper-V where databases are .VHDX on SMB3 from a Microsoft and Nutanix perspective? Kind Regards

Hi, Is there any way that we can monitor a particular VM activity - log file from Nutanix perspective. we keep on getting VM to be rebooted. VM OS: Windows Server 2008 Hypervisor: AHV

I found a problem that can not type a full stop symbol into User VMs under acropolis hypervisor but if I uesd a remote desktop connect to those User VMs It's available a full stop symbol I want to know that in this case it is a problem with IE or AHV.

Hello folks, I installed a 3node cluster with hyper-v on 1Gig interfaces. Now I want to "migrate" this setting to 10gig interfaces. If i disconnect the 1gig interfaces and plugin the 10gig interfaces the host disconnects and no services are functional. I have to disconnect the 10gig interfaces and reconnect the 1gig interface to reach the host/cluster. Is there a document which describes the procedure to change 1gig to 10gig interfaces? Or could anybody give me some advice? If i check the nic teaming on the hyper-v hosts there are 4 interfaces (2x1gig, 2x10gig) added to the NetAdapterTeam. Best regards, Freddie

Planning a customer migration of 15 physical servers and looking for supported options of P2V.I see links to the Sureline 3rd party tool. Is that the only direction or anything native from Nutanix yet.

Hello, I have had no issues building Microsoft Failover clusters using volume groups, vDisks, and MPIO; the procedure is very straightforward. Now I want to clean up a few test configurations and remove unwanted clusters, but I'm not sure of the best approach. How do I: List and remove attachments List and remove vDisks List and remove volume groupsI'm sure it's all in the acli; I'm hoping someone has already written a procedure. Thanks, Scott

I've been going through the nutanix SQLServer best practices guide and was wondering how relavent it is for AHV? mainly where it refers to different drives on different SCSI controllers? Regards, Stephen.

CIFS is supported via Hyper-V currently. Rumor has it that native CIFS for the NTNX File servers is scheduled for the NOS 4.6 release. Is there any pre-GA information on this?

Hello friends, I am new here nice to meet you and I hope you can help me.I am working with two Scenarios in my client. One we have Nutanix on its Linux KVM-based hypervisor and the other we have common x86 servers running VMware.The objetive is compare both solutions and decide what's best. (we want Nutanix to the best of course!)The application running on both of them is a jBOSS system, on 3 virtual machines. (application, DB and one apache front end.)I created a recording test using jmeter, where the user makes a lot of steps in the web interface (for instance, search for a specific person, click on the menu, etc). The test runs fine on the x86 server and VMware, but on the Nutanix, after 150 users, I always get: Started: 0 Finished: 0. And also the CPU Usage is higher than the other scenario. Almost the double.I added more CPU and RAM to the virtual machine, but it didn't work. I am also running on non-GUI mode, removed the listeners, added more memory to the "MaxNewSize", but nothi

Greetings community members! I am brand new to the Nutanix platform and have completed my basic initial configuration of my nodes on ESXi 5.5U2, however I am having trouble finding (not through lack of Google-fu) a complete guide on what Nutanix recommends as BPs for configuring hosts for ESXi. This raises some questions... e.g: Should I add anything to my node's Advanced Settings? Should I chanage the power settings Active Policy to High Performance? What is the definitive guide to HA settings with respect to the nodes, VM monitoring, policies therein, etcetera ? Not that this is an exhaustive list of questions, but I forgot to ask our Nutanix Pro Services rep before he left...and I could not immediately find what I need unless I am looking in the wrong place! :$ Edit: Some of what I asked is in the vSphere Administration Guide for Acropolis which is very helpful, but was curious if there is any additional documentation for Best Practices with Nutanix in vSphere. Apologi

Hi all, My present client is making me working on a design implying to deploy a XAAS plateform with a lot of security inside (NSX is on the cook list). In our team, i was declared as the nutanix man. My mission is to determine the best way to isolate storage from diffrent workload : we'll have an integration zone, a developpement and a production zone as PAAS. Some node will executed heavy VDI (K2 graphic cards will achieve this), Then we'll have a IAAS with vcloud SP for the sandbox zone).So we can imagine some sort of multicluster with 3 cluster dedicated to 3 zones : 3D VDI zone / SANDBOX IAAS zone / and PAAS zone. It implies at least 9 nodes which is a bit too much for starting plateform. My question is, can I make a 6 node cluster for nutanix / storage point, with 3 volumes pools on all 6 node ? and more than that what will it implies in terms of storage performance, data protection, data seggregation (security team will challenge me heavily on this part) ? Last but not

Hello all, I'm wondering if there is anyone out there using Nutanix with KVM as a hypervisor, and if so, what kind of management do you use for daily VM related admin jobs? - virsh/virt-manager ? - RHEV/virto ? - OpenStack on top? - other "cloud solution"? - custom tools/scripts ? Please share :) I'm quite curious about official / eventual cross-vendor support and/or "show-stoppers" you might have experienced or enlightenments you might have had.. P.S..: *psssst*...rumours have it, that Nutanix themselves are developing some "management tool" for KVM..anyone knows more?

Hi, I am new to hyperv.i added nutanix node to hyperv.but not able to see the container in hyperv.can anyone please advise how to view the smb share in hyperv.is there any need to add smb share to whitelist? please advise rgds ritchie

Hi, i'm doing a testing on Nutanix with AHV. there is a warning of "10G Compliance"-CVM is running in lower speed. any additional configuration that i need to to on nutanix? any guide? below is the snapshot

Hi Community, I would like to deploy Prism central to manage 2 clusters. Until now, nothing complex. The issue is : Prism Central is provided as an OVA to be deployed with ESX but I'm using KVM/Acropolis. Is there a way to import it ? Can you please provide me with some guidance ? Thanks a lot.

In case you hadn't seen the release notes for the Nutanix Acropolis Base Software 4.5 (previously NOS), Windows Failover Cluster is now GA and can be configured for SQL Server Failover Cluster Instances and other use cases with In-Guest iSCSI and MPIO support. Please check out the release notes and upgrade to 4.5 if you wish to use this feature. https://portal.nutanix.com/#/page/docs/details?targetId=Release_Notes-Acr_v4_5:rel_Release_Notes-Acr_v4_5.html

Hi All, I thought this might be of interest to people that want to use SQL Server with Acropolis Hypervisor. Which is fully supported by Microsoft under the SVVP program. So here is a way you can rapidly provision as many SQL Server DB's as you like. http://longwhiteclouds.com/2015/08/07/rapid-provisioning-of-sql-server-test-environments-with-nutanix/

My team and I was helping a customer troubleshoot a performance problem with their Oracle 11g R2 (11.2.0.4) database today and we noticed that it was taking between 90 seconds and 120 seconds to complete a checkpoint. Anyone who knows anything about Oracle knows that this is an eternity for a database to wait while switching online redo log files and continuing to process transactions. This was causing a lot of performance dissatisfaction for the customer, which is understandable. But it didn’t take long to figure out what the problem was and fix it. Literally changing a single parameter in the database and restarting the instance turbo charged performance by over 10X. First lets cover off some of the symptoms of this problem and give you some background before I give you the parameter we used to address the performance issue. Also note that this had nothing to do with the underlying infrastructure, it was purely a database level setting. This problem wouldn’t happen in Oracle 12c.

I have 3 x 3000 series node each with 256GBs of RAM, and 1 cluster. - 7.2TB Total SSD Flash (2.4TBx3 nodes)- 12TB Usable HDD (before de-duplication/compression)-  2.6GHz/20 Cores, 6 Physical CPUs: 60 Total cores-  768GB Total memory We are running pure Acropolis. The monster VM workload is a Progress database that is 7TB in size and has 200GB RAM allocated to it. We are setting this up as a PoC to migrate off a standalone ESXi host with a Violin all flash array. Previously, the VM on VMware was only pushing 12,000 IOPs. What should we be doing to optimize the performance for this VM? Multiple virtual scsi adapters? Also, is there a way to see if the working set is exceeding the node cache capability?

Hi All , As you know that to build a SQL cluster on vmware vsphere 5.5 I need to create RDM disk for both cluster's nodes with physical compitilty , and this will eliminate the vsphere from running vmotion (need to shutdown the host to migrate )since it is not supported. My question is : does nutanix support create a SQL cluster ? and how they will replace the RDM (the physical LUN)? And for licensing :Does nutanix base license support building critical application clusters for free? Regards,

Hello - Is MSCS (clustering VMs across physical hosts) supported on Nutanix? What ESXi/NOS versions support MSCS? How would I then present the shared disks (quorum, etc...) to the VMs? Thanks.
