I have 2 Windows 10 in esxi 6 on ssd datastor but hard speed in task manager is 3 mb/s I install esxi in dl380 g9 server . Is it normall speed ? How i can solve this problem?

    So little detail here... a) is the SSD local to the DL380, if so what's the EXACT part number of HPE SSD/s, what's the model of disk controller it/they are connected to and if they're in an array what RAID level, b) is your ESXi host up to date with patches, c) Did you use the HPE-specific installation ISO to build this host or the 'vanilla' one from VMware, d) Are vmtools installed on the W10 VMs and what's the exact disk configuration for those VMs, also what machine model are you using for these VMs.

You're facing this, very common, issue: https://www.reddit.com/r/vmware/comments/3r4zp8/esxi_6_unsuably_slow_disk_performance/

In few words, esxi is not for cheap raid controllers hardware. You need an hard raid with bbu and cache with write back mode to get rid of these. Or switch back to a non raid configuration with this hardware, and you'll have your IO performances back.

For the future please try to use better and deeper descriptions to ask your questions.

  • Perhaps try using supported SSDs, HPE don't support anybody else's disks, let alone consumer ones.

  • @farshad indeed, the issue I linked in my answer it's a matter only through the VMware virtualization layer. Once again: you should read my link to understand what's going on.
