Losing Network connectivity when take or delete vSpehere Snapshot on a VM

gca78 — Thu, 21 Jan 2021 18:11:47 GMT

Hello I have a problem with a Cluster Simplivity DL380 Gen10 version 4.0.1.184.
The problem is that when taking a snapshot of a VM in Vsphere or when making a backup with Veeam I have network cuts, I have observed that the machine several pings.

ESXi version is 6.7.0.15160138

Any ideas ?

@gca78 , this issue is a result of the way snapshot disks are consolidated and is somewhat expected behavior. The following VMware KB explains what is occuring during this process and why you may notice the brief and intermittent connectivity loss.

Hello, I can assume a brief interruption, but the problem is that when performing or eliminating Snapshot there is a network cut of at least 10 seconds (being optimistic),

This causes cuts in certain services that affect production.

@gca78 As snapshots are a function of VMware, a support case should be opened with them to further investigate. You may also open a case with SimpliVity support to be engaged on a call with VMware. The reason for the network loss would have to be investigated, but is typically due to I/O contention on the VMDK(s) needed to complete the snapshot operation.
