PVS Logon Process slow

[Björn Schläfli]

Hi all,

 

2 PVS servers W2K16, 64 GB RAM, 4 vCPU

130 target devices (2008R2 & 2016)

boot with DHCP options 66 & 67

 

Steps ip acquisition and bootstrap download are fast. After that the Windows logo is displayed for a long time and after that it jumps back to a black screen where it displays the pvs version, server and client ip and then OS boots.

Windows logo is displayed for around 1:26 min.

black screen with information for around 4 sec.

Virtual Disk Status boot time: 29 sec.

 

configured:

Threads per port: 4

Streaming ports: 6910 - 6947

Everything else set to default

 

Write Cache RAM with overflow

PVS vDisk Store on PVS local SSD Netapp disk

 

Interrupt safe mode is disabled.

PVS and targets are VMs on esx 6.5.

 

What could be the culprit here? How can I analyze this?

 

Thanks for your help.

Does it matter if a single target is booted, or multiple targets booted at once?

Assuming there are multiple ESX hosts, if the target device is on the same host as the PVS servers, is there any change?

Is it possible to reproduce on a vanilla windows 2016 image with only vmware tools and pvs target device software installed?

What is above in minutes, and what is the total boot time for the targets?

It was our fault. Shame on me. Our pvs servers have been moved and configuration hasn't been made correctly. Thank you

It was our fault. Shame on me. Our pvs servers have been moved and configuration hasn't been made correctly. Thank you. Boot time now 40 seconds.

What configuration on the PVS servers was causing this slow down for you? We seem to have something similar with a delay on the Windows Logo screen before showing various IP addresses and booting.

Hi Vavila15

 

Do you have news about the your issue? I have the same issue like you. I have a huge delay on boot until I see the IP address.

Hey, i'll try at my turn,

 

Same problem here. Can we know what is really done to correct the problem ?

[Markus Johne]

Same behaviour here. The Windows logo is displayed for a long time before the device information is displayed (IP, vDisk Name, etc. ), everything else seems to work fine

Hi,

sorry I've unfollowed this post. 

I can't remember exactly what it was. While Windows logo is displayed the image is streamed to the target as far as I know. Maybe I've forgot to configure Jumbo MTU or it was an esx configuration. Sorry I can't remember.
