Nutanix storage containers (selfservics vs default-...) - which is for what?

HiNutanix 6.6.2.5What is the difference for the following storage containers, except the replication factor, compression, etc..) ?  I mean what is meant to be placed for the certain containers.For example, when I deployd Prism Central, then there was an option between “default-..” and “SelfServiceContainer”, so my question is, which is for what (images, VM’s, etc..)..?Thanks.RegardsRaul

HA Testing

We have our Nutanix 5 node cluster installed with VMware vSphere 7.0U3. RF=2 so I should be bale to withstand a 1 node failure. I would like to test the HA capability of VMware/Nutanix by taking a node offline abruptly and ensure everything works as expected before placing production workloads on it.I was thinking of placing a test VM on a node and then pulling the power cables and ensuring that VM is powered up on a remaining host.Does anyone have any better or preferred way to test HA?

Getting stats for a VM seems to be different depending on the stat

While getting some stats for a vm the behavior seems to be different depending on the stat.Is there any documentation for specific stats? Sample Call:metrics: controller_avg_read_io_size_kbytes,controller_avg_io_latency_usecsstartTimeInUsecs: 1631290740000000intervalInSecs: 3600Output (see below):stat controller_avg_io_latency_usecs - give the expected output of a value for each interval since the input start timebut for stat controller_avg_read_io_size_kbytes - A single value is returned. What is the meaning of single value? Is it just the read at that point in time? Or is any calculation done behind the scenes? { "statsSpecificResponses": [ { "successful": true, "message": null, "startTimeInUsecs": 1632404100000000, "intervalInSecs": 3600, "metric": "controller_avg_read_io_size_kbytes", "values": [ 127 ] }, { "successful": true, "message": null, "startTimeInUsecs": 1631290740000000, "intervalInSecs": 3600, "

Availability of VM

we are using a two node cluster connected with a witness VM, issue is we are facing a downtime of 5 minutes because of transfer of windows vm from failure node to healthy node. we don't want any downtime because we are running Product Of Sell (POS) services in windows. we need seamless solution (e.g without breaking continuous ping).we don't want migration the issue is when the Vm is running on node A and node A fails, it took 5 minutes to start Vm on node B in failover condition ,so it create downtime we don't want this downtime.
