5 Essential Tips for Maximizing Your Experience at Nutanix .NEXT for Bloggers
Hello @LinKan You need to unpack the archives to the /var/www/html/release directory. Hi @Moustafa Hindawi : Absolutely I have unpacked the archives to the release directory. You can see directory modules and the related tgz and sign. But could not work.
Hello @Moustafa Hindawi :You can check below: I followed the LCM dark site guide to setup the local web server.
If I used dark site, is that means I need config dark site config?
Hello @LinKan From Read prospective, There is no performance impact From Write prospective, you are using NVMe SSD, you will have 1 tier in the extend store, 1st copy will be written locally, then another 2 copies will be sent to 2 another nodes. The main factor here in the performance is the Network configuration, I recommend 25GB ports. The most important question is, what is your cluster I/O latency now at RF2? @Moustafa Hindawi : We use 40GB ports for network traffic within Nutanix clusters.From overall cluster level response time, we can see less 1 ms except some high response time which is caused by SQL backup and restore period. I have another question for “How Nutanix deifne the write complete”: will Nutanix treat host write operation complete until two copies are written or just local copy is written. I think it is key for performance impact.
Hello ! What do you mean by “CG” ? CG means consistent group.
Alright, so to answer to your original post, as nearsync is built on async mecanism, i’d say CG are fully supported. https://www.nutanix.com/blog/nutanix-dr-multi-site-recovery About configuration of CG in a nearsync environment : https://portal.nutanix.com/page/documents/details/?targetId=Prism-Element-Data-Protection-Guide-v5_16:wc-dr-near-sync-c.html on step 3 within Configuring NearSync Disaster Recovery I know PD with PE could support CG in a nearsync environment. But how about Leap with PC? I checked the guide, it only support Async replications for CG.
Let me clarify more clearly:You can see below that CG in Nutanix Disaster Recovery supports only Async replication schedule. No Nearsync.
How Nutanix protection domain replication can be encrypted, is there any default encryption available or we need to enable the encryption. Yes. Nutanix supports this feature. You can check below for details.PD-Based DR 6.7 - Replication Traffic Encryption (nutanix.com)
I don’t think you could do that because microservices are enabled default. Prism self services also need microservices.
https://portal.nutanix.com/page/documents/details?targetId=Prism-Element-Data-Protection-Guide-v6_7:wc-cluster-leap-dr-encryption-wc-pc-c.html Yes, want to know how it works and my cluster is running 6.5 version No idea. But I find a very interesting thing is in the new and updated feature for AOS 6.6, the feature is updated. But I don’t know what’s is changing.
Any disadvantages configuring encryption for replication traffic I think it will have some kind of CPU overhead. But the percentage will depond.
I found some hints from Nutanix portal. In release notes from Foundation 5.5x which is announced on Oct 26th, it mentions: ENG-580063: Foundation 5.5 is now qualified for ESXi 8.X with AOS 6.7.1. So I think AOS would support vSphere 8 soon.
you would need to go to 5.2.5.1 (note this is EOL) that supports esx 7.0 U3 and from 5.2.5.1 to 6.5.4 that’ll then support anything 7.x but as of yet not esx 8.x the upgrade paths can be found here https://portal.nutanix.com/page/documents/upgrade-paths?product=nos&currVersion=5.15.4&tarVersion=6.5.4 thanks ,we will try this forgive me, i dont have nutanuix insight account. your answer is very clear, but i want confirm this again： aos 5.2.5.1 can support esxi7.0u3，and we have aos 5.15.4 lts > 5.2.5.1? can i say that we can update esxi to 7.0U3o? I think Khoskin missed one number. It should be 5.20.5.1.(The last AOS version for 5.20 family) AOS 5.20 is EOL now. So if you prefer to continue get support from Nutanix, it is better to upgrade the ASO to 6.5.
Futhermore, what’s the HW platform you use? I checked the Compatibility and Interoperability Matrix in Nutanix Portal, the Nutanix HW supports ESXi 7.0 U3 in AOS 5.15.4.Anyway, you prefer to upgrade the AOS to 6.5 or higher.

Anyway, you prefer to upgrade the AOS to 6.5 or higher. Thank your answer. we have 4 Dell xc740 server. so you mean I can update esxi 7.0U3o with 5.15.4? I prefer to update aos to newest,But I am fear to do this without nutanix support. Is it easy process to update aos with lcm? I checked the site, it only mentioned supported 7.0 u3. But checked the version 5.20, it mentions it supports 7.0U3f or specific version.You can create a case to DELL to check if your model support 7.0 u3o. At the same time, I think the best solution is you first upgrade AOS to 5.20 and then go to 6.5.Thanks!

Even if this time you could upgrade ESXi version to 7.0 u3o under AOS 5.15.4. So I think maybe you can purchase support services from Nutanix or vendor.

I have checked vmware hardware compatibility, it can work with esxi7.0o3. i just worry about if i can upgrade aos without nutanix support , is there a
I checked the Nutanix KB and extract some in this reply:NOTE: This workflow mainly applies to AHV and NTNX snapshots created via AOS. Typically 3rd party backup integration on ESXi or Hyper-V does not utilize Nutanix API calls and snapshot creation is handled via the hypervisor (VMware snapshots/Hyper-V checkpoints). However, depending on the backup vendor, this workflow can also be utilized on other hypervisors - some backup vendors can allow the utilization of NTNX snapshots instead of VMware snapshots or Hyper-V checkpoints.If integrated via the Prism VIP: An internal system PD is leveraged Temporary volume groups are created during the backup process and deleted once the backup process completes NTNX snapshots are leveraged API calls are used Anyone know which 3rd party backup software will leverage NTNX snapshots?
Here is my proposal:Run NCC health check every day. Set SMTP to send warning messages when there are some warning
It seems I find the solution. Using configure_lcm --enable_darksite -u xxxxx could change the mode to dark site. And I could do inventory sacn now.
DarkSite option is available under LCM → setting . You have loged in using different user, can you please login using admin user. and try again. The problem is that I could not see the setting. All blank. Checked the log, it seems always checking from Internet, but our env could not visit the internet.2023-11-21 06:21:52,288Z ERROR 78076080 download_utils.py:753 Failed to get file size of file at 'https://download.nutanix.com/lcm/2.0/master_manifest.tgz.v2.sign' with cmd '['curl', '-s', '-S', '-f', '-L', '-I', u'https://download.nutanix.com/lcm/2.0/master_manifest.tgz.v2.sign']'.RV: 7 Stdout:Stderr: curl: (7) Failed connect to download.nutanix.com:443; Operation now in progress So I guess system is keep trying and no feedback.
Hi, Lin, No, NSX-T is not required to deploy Nutanix Objects in VMware vSphere, what is meant is if y want to deploy Nutanix Object on VMware vSphere cluster managed by having NSX-T then it should be min version 2.4. Nutanix object is supported on VMware and AHV clusters only. F>P OK. Thanks. So IPAM is implemented by Nutanix Objects if I want to plan on VMware, right?
I think you can do what your proposal: disconnect the power cords one by one of a PDU and then reconnect they one by one to the new PDU, check the status after each disconnect and reconnect to make sure the status is normal.
@kondasani ashok You can check below docs link for your query:Prism 6.6 - Removing a Node from a Cluster (nutanix.com). Hope this link could help you.Thanks!
You can check the upgrade path from here:Nutanix Support & Insights
