Snapshots usage

Hi, I was hoping if someone can shed a light on some queries I have re snapshots. I am running low on space to the point where I currently have no autobuild resiliency. I do get a FAIL when it comes to snapshot_chain_length when checking with NCC.The value of that is 41 and ideally should be around 10. I have 3 protection domains with a total of 127 VM. I do a daily snapshot but only retain one copy. I have been getting too many snapshot alerts even when I only had snapped 50 VM in one protection domain. -Can someone explain what that snapshot_chain_length actually is and where the 41 comes from? -How much space is actually used by the snapshots? How can I get this info (NOS 4.0.1.2) -Each protection domain has 4 expired snapshots in addition to my one active snapshot. Do these actually take up space? What is their purpose? If I am not mistaken they can not be used for restores.

110, 220. Whatever it takes?

I was looking for confirmation about a statement that I recently heard that the best practice for the power supply voltage for a block was 220 volts. And that if 110 volts was used, it was less likely that one power supply could handle the load if one power supply failed. Thank you.

Backup performance on NX-1050

I currently have 2 x NX-1450, both are running NOS 4.0.1 and I'm using Hyper-V. Everything is linked up to 10Gb and I'm using a physical veeam server outside of Nutanix to back up both clusters, he is linked up to 4Gb. We are currently suffering from a bad backup performance, let's say something around 30-40Mb/s processing rate for one VM that is on a node that isn't doing anything at all. If I perform the same tests on an NX-3360, I can easily get up to 160-180MB/s processing rate, so that kinda rules out my network/configuration. Is there anyone out there running NX-1050 with vmware or hyper-v and Veeam and that can share their configuration/processing rates?

Esxi 5.5.0 Update 1 turn on iscsi?

Has anyone experienced this: When updating esxi 5.5.0 to 5.5.0 Update 1 using the update manager in vsphere, the host never reconnects. In fact, somewhere during the upgrade process, while the host is "down", iscsi gets turned ON whch causes the host to become unavailable to the vcenter server... helpdesk was able to run some commands in the ssh: # esxcfg-swiscsi -d# reboot to disable the iscsi and reboot the host which seems to fix the issue, (You have to manually reconnect the host once it is back up...) but I was curious as to the "WHY" of it all... Thanks all! Rick

Diagnostics VM Time to Deploy - 4.0.2.1

Good afternoon, Can someone please sanity check something for me, one of the BEarena team is running a diagnostics test which is taking 7-8 minutes to deploy each diagnostics VM. What is considered to be a normal amount of time? At this rate the 8 node cluster will take over 1 hour to run diagnostics. Thanks Darryl

Temporary ip and name for CVM

Dear All , For importing Vm's from the existing vmware envirronment to Nutanix cluster I extracted the below note from Nutanix admin doc. [i]Note: Due to a limitation with VMware vSphere, a temporary name and ip address of a controller VM must be used to mount the Target NFS datastore on both the source host and the target host for this procedure.[/i] 1.Could you please help in this what this temporary name and ip mean? the CVM ip addrress of the nutanix host is already configured ,shall i need to modify it ? or keep it as it is? 2. For target host (Nutanix Host) it is clear that it contains CVM but for the current (Not Nutanix Host) there are no CVM. 3.This should be done through adding storage on both hosts .Right? Mount the target NFS datastore on the source host and on the target host (you can mount NFS datastores in vSphere client by clicking Add Storage on the Configuration>Storage screen for a host) [b]so instead of using the CVM ip of the target host (Nutanix Host) in Se

NX-1050 - No Virtual CDROM

I have an NX-1450. I'm using the IMPI to mount a new Phoenix ISO. The IPMI CD-ROM Image status message shows "There is a disk mounted." However when I power cycle the node and hit F11 to bring up the boot device menu, I don't see an IPMI Virtual CDROM in the list at all. What could I be doing wrong? Here are the boot devices I see.

Do we need to backup anything like configs/settings to a USB drive in case of a serious outage?

I took the admin course two weeks ago and have been tasked with writing an operations manual. One of the sections relates to backup & recovery so my question is "Do we need to backup anything like configs/settings to a USB drive in case of a serious outage?". If not, how does one recover from the most serious of outages? Being new to Nutanix, I'm not even sure what a catastrophic outage would entail so if someone could articulate same and provide a high level recovery process, I would be most appreciative.

CVM Start

Hello folks, Recently I was running some Resilency testing, powering down a node using IPMI (Power off server -= Immediate) to ensure VMware High Availability worked as expected for a simulated power outage. When I finished I powered the node back on via IPMI. I was surprised the CVM did not automatically start. Is it expected that the CVM would not restart when a node was powered back on? Thank you for your help.
