My mistake. I was sure that something should had been invented in order to reduce fragmentation during parallel writes. My apologies.Can you explain how fragmentation would not be reduced by having only one VM processed at a time? With 4 VMs all writing to the target at the same time their data blocks will be interleaved with each other as the target allocates free space to write to. Simultaneous writes is a classic cause of file fragmentation.
Your logic is correct, that's why there is no parallel processing for compact operations.If I enable compact full, and all 4 vms start compacting their fulls at the same time, I'll have the same problem ... simultaneous writes to the same data store = fragmented files.
Good to hear that. Feel free to contact us if any isuues arise.after reconfiguring veeam to use the good interface, I'm now seeing processing rate around 35MB/sec. yeah!
