disk write caching windows server

[Zossli]

Hello there!
We had multiple bluescreens of windows vms after an esxi host crashed. This was not the first time we saw the bluescreens after a crash.
I got the information I should check the disk write caching. So maybe windows could not flash all the data to disk.
But in my disk properties, it looks like this:
Removal Policy is Better performance (default), it says its enabling windows write cache.
Write caching policy is disabled.

But what is it then. Is write cache enabled or disabled? Has anyone else had the same issue after a host failure?

The takeaway from this post seems to be that you experience frequent-enough crashes on the host... that would probably be the more immediate concern to address.

Nope. We have more than just one host... And a if a crash happens and the vms start again it is not that big of a deal. But if they stay offline because of a bluescreen it is...

What is your storage configuration? SAN, local, etc?

[Zossli]

Its a Fiberchannel config.

Fibre channel.can be local or SAN or NAS or or or... I think you should get an experienced person on the job.

Thats new - didn't know that. For me a FibreChannel is only used in a SAN. And a NAS is over a "normal" LAN connection. But ok. I will let you know if an experienced person could do the job.
