Nutanix Cloud Infrastructure

I saw a tweet today (shown below) that reminded me of 27th August, 2012. This was the day that VMware published this article, which demonstrates how VMware vSphere (5.1 at that point) could achieve 1 million IOPS in a single VM. Things have undoubtedly gotten better in vSphere 5.5, and even more so with vSphere 6.0, which was recently released. Even though the test setup at the time (3 years ago) required two dedicated all flash arrays for this one VM, it demonstrated clearly that the hypervisor is not a bottleneck to storage. It also clearly demonstrated that even using VMFS and going through multiple layers to the storage and back, isn’t a bottleneck to high performance. vSphere itself adds so little overhead that it’s a great platform for running any workload. This is important, because 3 years on from this test we have all sorts of things running on top of vSphere in the ever increasing capabilities of the platform. Even high performance storage controllers and not just the varie

If you're interested in running Oracle on the Nutanix platform then you should check out my latest blog article titled Oracle Licensing and Support on Nutanix Virtual Computing Platform - http://longwhiteclouds.com/2014/05/11/oracle-licensing-and-support-on-nutanix-virtual-computing-platform/. We are in the process of publishing a Tech Note on Oracle for Nutanix and also a Best Practice Guide. These should be available on our web site in the next few weeks.

Just wondering if anyone has tried the NOS upgrade interface and had good success or issues. I am looking to do it this weekend, but I don't see any documentation on it. Thanks!

Hello, Is there an official stance on upgrading to/using ESXi 5.5U2 as install media? I see that U1 is specified explicitly on the supported Hypervisor list, is there a target date for U2 certification?

In addition to the video I recorded regarding SQL Server Provisioning with VAAI I've written an article tonight including the scripts I used to clone the VM's, tune the network, and the RunOnce script that ties it all together. I hope this is helpful. http://longwhiteclouds.com/2015/01/27/nutanix-sql-server-db-vaai-clone-performance/

I'e just published a video demonstrating provisioning multiple SQL VM's in just minutes using VAAI Clones on the Nutanix platform. The SQL DB VM's are 435GB in size, but due to VAAI the new clones don't use any additional stroage capacity initially.Nutanix Provisioning SQL Server VM's with VAAI Clones  

We were one of the first guinea pigs to host Exchange 2010 on Nutanix. our cluster consists of a 3451 and a 6220. We have 1 exchange server tied to each of the 3451 nodes, 4 in total. Each server is configured with 4 2 TB databases. 2 active, 2 passive. We noticed recently as we migrated a majority of our users to the new environment that we are getting alarms that we are hitting a threshold of disk space per host. Not sure what we're missing here.

Hi, I have a curios doubt. I read about cloud connect and summarized that it is mainly for backing up the data! And when I connect to a public cloud AWS, a CVM will automatically be created on that platform right! So can I seamlessly offload some of the production workload onto the cloud as well or is it exclusively for backup and restore ? Best, Narayan

Hi , Does Nutanix has it's own backup software to take scheduled backup for production VM's created on ESXI hosts ? or I need to use third party backup solution like Veem or netbackup? if available , does it require base license or enterprise license please note the from prism in licensing part I saw the field Dataprotection and deduplication and others with status off,is this mean that these functions are not supported with the current license or just need to turn on? Regards

Hey there We have a Windows Azure Pack environment deployed on a Nutanix Hyper-V based infrastructure. The infrastructure is build with high availability in mind: Redundant Virtual Machine Manager configuration Redundant SQL Server configuration (using SQL Server AlwaysOn)But we are currently facing an issue setting up a redundant VMM Library Share. Microsoft does not allow using a redundant VMM installation as the Library Server. Instead they recommend to setup a Scale-Out File Server infrastructure as the Library Server and then add your Library Share to it. However, to my current understanding, it is not possible to setup a Cluster Shared Volume on Nutanix Hyper-V - which is a requirement for a Scale-Out File Server. What are the design recommendations from Nutanix in this matter?

Dear, Does any one know when deploying oracle rac in Nutanix Box whether it is following vmware best practice or any special deployment? Regards, Kelvin

Storage DRS is a feature of vSphere 5.0 onwards which aims to reduce the complexity of managing storage capacity and performance for virtual machines running on traditional shared storage. SDRS helps simplify management of Datastores (LUNs / NFS Mounts) by analyzing the available datastores capacity and placing new virtual machines in datastores with the required available capacity. This is called "Initial Placement". SDRS also allows administrators to create rules ("Affinity" & "Anti-Affinity") to ensure specific what VMs should be kept together or apart for performance / capacity reasons and finally, monitor I/O metrics and relocate VMs to different datastores where contention or capacity constraints exist. As it is recommended to have one Large NFS Datastore in a Nutanix environment, the issue of initial placement (which SDRS helps resolve) is natively eliminated as all Virtual machines, regardless of performance or capacity requirements can and should be placed into one NFS Dat

Network I/O control is a feature available since vSphere 4.1 with the Virtual Distributed Switch (VDS) which uses Network resource pools determine the bandwidth that different network traffic types are given. When network I/O control is enabled, distributed switch traffic is divided into Customer Network Resource pools and/or the following predefined network resource pools: Fault Tolerance traffic, iSCSI traffic, vMotion traffic, management traffic, vSphere Replication (VR) traffic, NFS traffic, and virtual machine traffic. From vSphere 5.0 onwards, you can also create custom network resource pools for virtual machine traffic. You can control the bandwidth each network resource pool is given by setting the physical adapter shares and host limit for each network resource pool. The physical adapter shares assigned to a network resource pool determine what share of the total available bandwidth will be guaranteed to the traffic associated with that network resource pool in the event o

Is anyone running Microsoft Exchange on their Nutanix cluster? If so, approximately how many mailbox databases (EDBs) are you running and what is the approximate size of each? Also, overall feedback/thoughts of the performance of your Exchange environment on the Nutanix cluster?

Hello mates, We have 2x NX3350 and Arista switch which handle roughly 100 VM. Workloads are: 20x VM with heavy disk workload which are used mainly for reporting and analysis. R/W ratio is roughly 50/50. They created 20K IOPS workload when they lived on SAN storage with RAID10 and tiny flash tier and average latency was always below 5 ms. 10x VM which are used for application virtualization 70x VM which are use for desktop virtualization. Now, when we migrated to Nutanix, we have only 4K cluster IOPS and 20 ms latency which does not seems to be very good for us. Trying to resolve the issue, we enabled inline compression and increased CVM memory up to 20GB. We also tried to change tier sequential write priority. Unfortunately, this does not help. ncc, cluster status and prism health claim that everything is ok. Before we migrated our environment, we've run diagnostic VM and the results was roughly 100K IOPS for read. Here is the current configuration of cluster:NOS Version: 4

When we want to reconfigure for HA, installation of the fdm always fails with the following error: syslog.log:2014-09-10T07:34:33Z fdm-installer: VIB Nutanix_bootbank_pynfs_5.0.0-0.0.1 violates extensibility rule checks: [u'(line 22: col 0) Element vib failed to validate content'] We need to remove pynfs, reconfigure for HA and then we can re-install pynfs again. Is there a workaround in stead of keep on removing and reinstalling pynfs? Regards John Grinwis

Is anyone using Veeam to backup their virtual environment on a Nutanix cluster? If so, how have you configured your backup proxy (how many, virtual or physical, 1 arm or 2 arm configuration, etc)? What are you using for a backup target? What kind of throughputs or processing rates are you seeing? I am running some test jobs, and a few of the jobs I have run identify the soure (Nutanix) as the bottleneck in the job. My backup proxy is a VM with a 2 arm configuration (1 vNIC in the production storage VLAN and 1 vNIC in the backup storage VLAN) running in Network Mode. I'm wondering if there are other modifications I can make to alleviate the source (Nutanix) from being the bottleneck in the jobs.

Hello everyone, Does anyone have an official date for the support of vSphere 5.5? And with 5.5 update 1 right around the corner (next month or so), do you now if the U1 version will be supported on the release date or will we need to wait some more? For what it's worth, our block is running fine in 5.5 since ~1month (although unsupported by Nutanix, we updated it with VUM without problem). Thanks in advance for you answers, Sylvain.

Can someone enlighten me, why KVM uses iSCSI-LUNs and not the NFS exported container like it is done with vSphere/ESX? Currently, I only see disadvantages, like cumbersome handling of VMs, and no benefits.
