Slow Transfer speeds

New Nutanix install - vSphere 5.5.0 While transfering a 200GB file on a Virtual Host from the C: Drive to the E: drive I'm not getting anything faster than 50mb/s and sometimes down to 25mb/s. Anyone else seeing this type of behavior? Or have a solution to resolve slow speeds?

Incompatibility with Server 2016/Win10 and 2012r2 Hyper-V Cluster (AOS: v4.7.1)

AOS: v4.7.1 Server Platform: Multiple Hyper-V (2012 r2) clusters It appears that if you whitelist an IP that belongs to either a Server 2016 or a Windows 10 machine, that machine still can not access the SMB share being published by our Nutanix (v4.7.1) clusters. We found this out after upgrading our SCVMM server to Server 2016. At this point, the VMM server can 'see' the shares but can not calculate share size (reports 0GB) and therefore can't manage the share(s). Since then we've tested with multiple other 2016 and Windows 10 machines - all with the same result: added to the whitelist but can't browse the share, even from Windows Explorer. We are looking for confirmation that this is a known issue. If so, can you confirm if it's resolved by an upgrade to v5.0.2?

fdm and pynfs

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

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

Veeam One VM heartbeat alerts nightly in a chain by host

This is really weird, every night we are getting veeam one "Heartbeat is missing for VM" alerts from every guest in our protection domain, in a chain, by host. For instance, one host starts at 6:30pm and is all resolved by 8:50pn, then the next at 12am and resolved by 5am, then the last at 8am and resolved by 820am. We don't have backups going at 6pm (they start at 8) and the snapshots go all day, hourly, so it can't be those causing it. Seems like some sort of nightly maintenance on the hosts that would be causing the issue. Any idea where I could look to see those logs?

what about memory management on ahv

Hi everyone, I'm struggling to find some documents about how ahv manages the virtual machine's ram. As far as I know, it doesn't share ram among vms....but, for example, what about overhead? Is it necessary to consider some overhead in addition to guest ram?Thank you all

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

AHV VM CPU Usage consumes higher % than ESXi?

My customer reported that in their test, the CPU Usage of AHV VM always consumes 10% higher than ESXi so I am going to find out what is the most suitable reason behind this problem I have searched around and find out this blog below that having a paragraph pointing about hypervisor bottleneck: "The Nutanix Controller VM (CVM) runs on top of multiple hypervisors and delivers excellent performance, but there is always room for improvement. With our extensive experience with in-kernel and virtual machine based storage solutions, we quickly learned that the [b]biggest bottleneck is the hypervisor itself[/b]."

On the other hand, I have tested by myself on the scenario in which I have built up 2 VMs with the same configuration on 2 clusters having same Nutanix model and run the CPU tes
