SAP on Nutanix

Does anyone have some experience with running SAP on Nutanix, doesn't matter if it runs on HyperV or VMware. Oracle or MS SQL is ok. Just looking for some feedback and best practices. Kind regards Bart

PostgreSQL Performance

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: [url=http://longwhiteclouds.com/2014/11/27/performance-testing-mysql-and-postgresql-with-hammerdb-and-pgbench/]http://longwhiteclouds.com/2014/11/27/performance-testing-mysql-and-postgresql-with-hammerdb-and-pgbench/[/url] Unfortunately, the Performance does not meet our expactation compared to our old PostgreSQL server running on a NetApp Filer.

Hypervisor Upgrade (ESXi) using One Click (Host Maintainance Mode issue)

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

Exchange on Hyper-V

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

Hyper-V Cluster change to 10Gig

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.

Removing an Microsoft Failover Cluster

Hello, I have had no issues building Microsoft Failover clusters using volume groups, vDisks, and MPIO; the procedure is very straightforward.

How do I: [list] [*]List and remove attachments [*]List and remove vDisks [*]List and remove volume groups[/list]I'm sure it's all in the acli; I'm hoping someone has already written a procedure.

NOS 4.6 CIFS?

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?

jMeter On Nutanix

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

VMware ESXi Best Practices

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! :$ [i]Edit: Some of what I asked is in the [url=https://portal.nutanix.com/#/page/docs/details?targetId=vSphere_Admin-Acr_v4_5:vSphere_Admin-Acr_v4_5]vSphere Administration Guide for Acropolis[/url] which is very h

Network and storage segregation

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 : [list] [*]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).[/list]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. [b]My question is[/b], 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

KVM Hypervisor - Management

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.. [i]P.S..: *psssst*...rumours have it, that Nutanix themselves are developing some "management tool" for KVM..anyone knows more?[/i]

So here is a way you can rapidly provision as many SQL Server DB's as you like.

Turbo Charge Oracle Database 11g Performance

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.

Progress Database optimization for Nutanix cluster - Monster VM on Acropolis

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?

Does Nutanix Support SQL Cluster on ESXI5.5?

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,
