Oracle + Dual hypervisors in 1 Cluster

Hey Guys, I have a question: Let's say a customer needs to deploy some Oracle databases. As wel all know, licensing is expensive.. In this scenario they have a 11 node cluster. Would it be possible to have 2 nodes run on AHV with oracle whilst the remaining 9 nodes run on ESXI?(They only need 2 nodes hence they don't want to use a third node & create another cluster + They would like to benefit from erase coding.) This would cut the Oracle costs by a huge amount. Or are there any other solutions for this? Thanks in advance! Sebastiaan

Storage Containers - business purposes for many - or is that a bad thing?

Hi All I have read that a single storage container is all that should be used as Nutanix takes care of all the functionality like de-dupe and ssd allocation. I started my Nutanix journey with a number of containers for dividing into business parts eg: Production SQL, Production Web, Dev, and Test. Is this division a sensible way to go or do the latest versions of Nutanix negate that? I intend to limit dev and test to slower drives in the pool, is that possible outside a container approach? Many thanks E.

should i use a witness

I am looking for other customers who have used the witness feature. We have three buildings each about 1 mile from each other. 10g fiber between them. We have two Nutanix clusters, one in each of two of the buildings. We have the ultimate licensing and are already using Metro clustering. I have the fail over set to manual. Today I setup a witness server in the third building. As far as I can tell everything is working. The real question is should I use it? Is anyone using the witness. Does it cause more problems than it solves. At least with manual I have full control when a fail over happens. So far it has been easier to fix my issues than to fail over and almost all issues are network related not nutanix.

Prism and DVS Iissue

I have encountered an issue while migrating to a dvs, I am running esxi 6.5 on a 3 node cluster. The setup is new so there are no VMs apart from the CVMs and a test VM on the host. The dvs already exists and I am doing one node at a time and as such I added one of the NICs from node A to the dvs. I then did a quick test with the test VM on each port group I have configured to confirm connectivity. I then attempted to migrate the VM Network port group created on vSwitch0 that the CVM on node A was connected to, the migration "worked" but connectivity to the CVM was lost. In addition to losing connectivity to the CVM on node A, I am now unable to access prism from any of the CVMs or cluster IP. The page loads but once I attempt to login nothing happens. I even powered off node A in hopes that I can get to prism but still no luck. All CVMs and the cluster IP are reachable via IP, the esxi hosts for node B and C are also fine and reachable. Not sure where to go from here other than tear do

Where can I find NX Physical Specs?

I’m in the sales process and the customer is asking me about the physical requirements of an NX appliance (particularly, the NX-1365-G6). Where can I find this information? Like power consumption, thermal dissipation, dimensions, etc... I know there are some [url=https://www.nutanix.com/products/hardware-platforms]here[/url], but they don’t list all the products there.

LCM updates without DRS license ?

ESXi - Storage Containers/Datastores and vMotion Operation Limits

We are planning a major migration from existing 3-tier ESXi over to Nutanix/ESXi (AHV to come later). Due to time constraints in our move, we are trying to optimize how many VM's can migrate at one time. VMware has a few well-known limits on their operations: vMotion operations per host (10Gb/s network) - 8 vMotion operations per datastore - 128 Storage vMotion operations per host - 2 Storage vMotion operations per datastore - 8 If I take a "one storage container to rule them all" approach, I will be limited to 8 migrations at once, as long as I spread out my migrations to 4 hosts. My target will be a 14 node cluster, so I would like to push up to 28 operations, if at all possible. Would it be considered a best-practice to carve out 4 storage containers, knowing I'm still in the same pool, and fan out the migrations to get around these limits? My goal is to saturate my 10Gbit inter-datacenter link. Yes, I like to push the limits (break things?). Would the multi-data

Communication trouble of CVM when building CE on Nested ESXi

Dear All, I am trying to build Nutanix CE into the environment of Nested ESXi. I downloaded and prepared the latest version of ce - 2018.05.01 - stable.img.gz. The ESXi to build the AHV is 6.0. First of all, we started to work as a single node cluster, we plan to develop into a 3 node cluster if it works. 192.168.0.27/24 to AHV, GW: 192.168.0.254. I set up CVM 192.168.0.28/24, GW: 192.168.0.254 and started the installation. After waiting for a while, a message stating that the installation was successful is displayed and the message "Nutanix CVM IP: 192.168.0.28" is displayed. However, only AHV can communicate with this CVM, and it can not communicate with other devices on the same subnet. If you check the Arp Table of another Linux machine on the same subnet, the correct MAC address of CVM is registered but the MAC address of this Linux machine is not registered in the Arp Table of CVM side. Only the MAC Address of AHV is registered in the Arp Table of CVM. CVM can not communic

Nutanix operating in a 'private' cluster (feature workarounds)

Hello, In setting up Nutanix we do not allow it on the Internet. How much does this constrain what we can do with it? ie Life Cycle Management (LCM) Although LCM allows us to point to a different source we will still need to get the Modules somehow? Although LCM lets us start an Inventory it still seems to want to go out and get a Manifest file and then it fails? Can these be downloaded somehow? Where else are we going to find difficulty with? Thank you...

Hi Team, We have multiple Nutanix clusters with Dell XC servers installed with ESXI servers. We found an user account "PTAdmin" present in Dell iDRAC servers. Is there anyway to disable the account from CVM or Hypervisor since we have 100+ nodes in the infra. Thanks.

Storage Node - disk utilization

We added a couple of storage nodes to a modest 3-node cluster that was running out of disk space. The alerts about running out of storage, and not having enough for redundancy, are gone. A few months in, and every time I look in Prism, under Hardware, I see that the storage nodes' "Total Disk Usage" has not gone up very much. The compute nodes' disk usage is about 5-6 times as much as the storage nodes (and the compute nodes actually have more storage onboard than the storage nodes). I understand that Nutanix tries to keep a VM's storage on the same host that provides its compute resources (and the copy is sharded and spread out among other nodes). Is that why I am seeing so little utilisation of the new storage nodes in Prism?
