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
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

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
Hi All I'm a Nutanix partner in Thailand, when I present Nutanix product in DR feature one question alway arise from the customers who seriously interest in this feature. "How to caculate WAN bandwidth ?", that mean to how effective compression and deduplication of DR feature. I can not find this information on the Google and Nutanix site. Please advise me. TIA.
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.
Anyone aware of a problem when using (unable to authenticate) domain local AD groups in PC 4.6? Worked before we upgraded to 4.6, but seems that a domain local AD group fails.
Is there any change Nutanix will expose API for Third Party to use Nuatnix Time Stream, and snapshot for Backup Solutions like Netbackup. vF.P
Hi, I'm still digging into Async DR functionality. As I understand, Async DR will replicate changed blocks from Site A to Site B at given interval from an active protection domain to an inactive protection domain. Let's say now, I do a Site A shutdown to test the DR processes. I therefore activate site B protection domain, register the virtual machines, and boot them. So far, so good. Now, I restart site A, and I want to fail back. I shutdown all virtual machines on site B and Site A (if any running), deactivate PD on site A, and setup replication from Site B PD to site A PD, and run a manual Sync. Does this make sense ? And will this copy only data changed since fail over occured ? or will it do a full sync ?
Good morning... evening... night all over the world ^^ I'm wondering what are the technical differences between Async DR and Backup. What I've red in documentation is that Backup does not allow running the virtual machines on the remote site. This comes with many questions as I couldn't find any detailed description of the backup mechanism. As far as I understand, both works exactly the same. Only difference is that on the remote site, the backup target PD cannot be promoted to allow running of the VMs. Is this correct ? is this the only difference ? Otherwise, what are all the differences between both modes ? Any impact on the size of used on the target space ? ...
Hi, I couldn't find this in the documentation. As I understand, the choice of Async DR vs Backup is to be made at remote site configuration. I would like to replicate some VMs for DR, and some for backup only. Is it possible to create two remote sites in a cluster pointing to the same remote site, thou allowing to have one remote site set as " Async DR" and the second one as "Backup" ?
Thoughts I'd post this rather than bugging our SE over and over ;) Trying to get a disaster recovery plan in place to protect against a major disaster such as server room fire... We have a couple of clusters geographically separated which I have set up as remote-sites. Site A and B lets call them. I've set up a PD w/ consistency group with the VMs to protect and periodically snapshot from site A to B. Now in the case of a fire/destroyed cluster at site A... obviously step one is rebuilding a cluster at that site with the appropriate configs, but then... With a brand new cluster in place, what is the standard process to retreive the snapshots from site B back to the new site A ? So far, I've activated the backup on site B (as if it was an unplanned outage and left it off). and recreated the remote-site link on the newly built out site A. I am thinking I now create a new PD to shuffle the VMs/consistency group back to Site A and then activate there and I am done ? I know this
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
Hello, Has anyone had success making Hyper-V VM level backups up in to the cloud? We were going to use DPM to send backups up there but it requires an agent to be installed on the SMB server so it wouldn't work on Nutanix. We also looked at Azure Cloud Connect to replicate our containers to Azure but that is backing up at the container level and restoring an individual VM can be difficult. What have you been using to achieve offline VM level backups? My organization's goal is to go back to any point within 35 days and the backups must be in the cloud(Amazon or Azure, prefer Azure).
From this tech note - http://go.nutanix.com/rs/nutanix/images/TechNote-Nutanix_Storage_Configuration_for_vSphere.pdf, my impression is that Nutanix thin provisions a VM if the disk are set to "Thick Provisioned Lazy Zeroed". All Nutanix containers are thin provisioned by default; this is a feature of NDFS. Thin provisioning is a widely accepted technology that has been proven over time by multiple storage vendors, including VMware. As containers are presented by default as NFS datastores to VMware vSphere hosts, all VMs will also be thin provisioned by default. This results in dramatically improved storage capacity utilization without the traditional performance impact. Thick provisioning on a VMDK level is available if required for the limited use cases such as fault tolerance (FT) or highly demanding database and I/O workloads. Thick provisioning can be accomplished by creating Eager Zero Thick VMDKs. Eager Zero Thick VMDKs will automatically guarantee space reservations within N
Hello, Is there a way (other than REST or scripting/crontab) to put any new VM created inside a container to a "default" protection domain? The rationale is to create a "standard" policy for all VMs of a cluster like "this cluster is replicated every 2h, by default", then if exceptions need to be handled, they can be treated on a case by case basis. I have a customer that is PoCing Nutanix, with the goal to move from a NetApp/NFS/IBM Blades solution to Nutanix if everything goes well. Problem is, they use SnapMirror to replicate their datastore (1 by cluster) every 1h. They do want to be able to replicate just a VM, but they don't want to have to add each new VM individually to a protection domain. Sylvain.
trying to connect the maxCapacity and totalImplicitReservedCapacity fields with data from Prism gui. As of yet, unable to connect the dots. I'm assuming the amounts being presented from the cmdlet is in bytes. If so, I've got 28TB per the cmdlet in way of maxCapacity, but the Prism gui for that container returns 24.48TB as the max capacity. --- example out put from cmdlet PS C:usersmeDesktop ools> Get-NTNXContainer -Id 00052bfc-1527-12fd-46e3-246e96026620::13840122 id : 00052bfc-1527-12fd-46e3-246e96026620::13840122containerUuid : f72335e2-bf87-4c9c-a7db-64cf3ce5e88aname : D-RTP-A1-NTX-XC630-1-P-01clusterUuid : 00052bfc-1527-12fd-46e3-246e96026620storagePoolId : 00052bfc-1527-12fd-46e3-246e96026620::13storagePoolUuid : f0efd6cb-8839-43a0-b30f-c2aad97ce5demarkedForRemoval : FalsemaxCapacity : 30999844125064totalExplicitReservedCapacity : 0totalImplicitReservedCapacity : 14227079168000advertisedCapacity :replicationFactor : 2oplogReplicationFactor : 2nfsWhitelist : {}nfsWhitelistI
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.
Hi, Does anyone have any experience backing up VMs (specifically Hyper-V VHDX files) running on a Nutanix cluster using EMC Networker? Was the backup done using the Hyper-V agents, or was direct Nutanix SMB share backup taken advantage of? If there are links to help or steps to follow, it would be of great help. So far, all I find is help for Veeam. Thanks, Schubert
We've got a 11mb pipe between sites that bursts to about 20. We have some PD's that we've set up with about 30 machines in them and turned on replication. Its not surprising that initial replication is going very slow and we have an estimated completion time measured in months. Both sites are in production. I can't take on cluster down and bring it locally to the other site to get the intial replication done at high speed. Is there a white paper or procedure or even someone in here who's got some tricks to help us get replication moving? I was thinking of Starting a new PD, setting up replication, then adding one or two machines at a time until it's full and replicated. That seems pretty tedious and very time consuming. Any help would be appreciated.
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'm fairly certain this is possible, but going is rough for finding it documented. Let's say I have a remote container setup in a NTX cluster in LA. Can I created protection domains in a NTX cluster in Miami and NewYork and point them both to the remote container in LA? Sort of a many to one type approach in using protection domains and any limits on how many you can point at one? Any documentation anyone's found covering this and docs on where the snaps are stored (I don't see them in the ESXi datastores) and how much data is used from remote snaps. Thanks!
