I've been planning to run ReFS within our infrastructure for some time now, but just seem to get the chance to now. So before I begin digging into configuring the test environment, so while I go grab DiskMon, ProcMon and Iometer,

I was wondering if there already is some reports that would provide some insight, my main concerns would be:

  1. Would it be possible to use it as a CSV?
  2. How would it perform in an Read majority environment?
  3. Are there any known best configurations for its replication between sites?
  4. Are there any drawbacks/benefits of activating FileIntegrity?

Any help would be greatly appreciated!

  1. Yes.


To use CSV, your storage and disks must meet the following requirements: File system format. In Windows Server 2012 R2, a disk or storage space for a CSV volume must be a basic disk that is partitioned with NTFS or ReFS.

  1. Like NTFS or better.

  2. Windows doesn't replicate @ file system level. These are either files with DFS-R or blocks with Storage Replica.



  1. Yes, ReFS turns itself into log-structured file systems and whole I/O patterns changes dramatically.


People are having lots of issues with ReFS running in log-structured mode. Here's a good example of that.


I'd suggest to sandbox your brand new ReFS environment for quite some time before putting everything into production!
