Networker with FLR with network segmentation

Hello community

 

I am trying to understand in detail how Networker works with Vmware integration in a environment that is heavily segmented with firewalls and only ’must have’ traffic is allowed.

 

Everything else I have figured out but about FLR I do not find enough documentation.. or missed it. So things I have not found:

- who/what provides the FLR agent installation source

- can it be downloaded and distributed and kept at latest version with guests native and centralized software tools

Also I have missed the information what component are active and with what protocols when FLR is in action, how all the necessary hand shaking and data flow from ddboost device/vproxy/storage node/hypervisor actually to target happens

 

Any pointers to information would be nice

 

Br,

Hello,

Here are some insights on the information that you were looking from

- who/what provides the FLR agent installation source

The FLR agent is being copied over to the respective VM by the proxy which is selected for the restore process.

- can it be downloaded and distributed and kept at latest version with guests native and centralized software tools

You can copy it from the vProxy host and pre-install it over to the VM's. The installation files somewhere inside the /opt/emc/vproxy folder. If you are doing this then you will have to maintain the versions in case you upgrade the proxy.

These are the high level steps :

The restore when triggered is all handled by the vProxy,

  • First FLR agent is installed on the target VM, if the agent is installed it makes sure that the service is started.
  • Next the image for selected VM is imported as NFS from the Data Domain and attached to the ESX hosting the VM at that moment. So this needs a NFS port open to the DD.
  • A temporary datastore is created from the mounted NFS
  • Then vmdk from the NFS Datastore is then mounted to the respective VM, the mounting of the FS is done by the FLR agent that is the reason why Administrator/root credentials are requested during on the restore wizard.
  • Once the FS is mounted, you can browse the files/folder and restore the files that you need.
