Key Sections:

  • Audience: Guidance for configuring MPIO for QSAN storage on Windows Server 2022.
  • Environment: Host OS Windows Server 2022; example storage XS3324D / XF2026D / XF3126D; firmware v2.2.0; 16 GB RAM; iSCSI data ports configured per controller.
  • Topology: Dual-controller iSCSI paths between host and storage.
  • Configuration:
    • Login to XEVO UI → Data Ports > iSCSI Ports → set IPs (e.g., CTRL1 192.168.175.70/24; CTRL2 192.168.175.71/24) and verify ping.
    • In Windows Server Manager: Add Roles and Features → enable Multipath I/O.
    • Create pool, volume and host group; map LUN to host.
    • Use iSCSI Initiator to log in to the target from the host.
    • Open MPIO (Tools) → Discover Multi-Paths → check Add support for iSCSI devices, select the QSAN device (e.g., “QSAN XF2026”), and click Add.
    • Confirm the disk becomes a multi-path device (no reboot required).
    • Set the MPIO load-balancing policy in Disk Management → disk Properties → MPIO tab.
  • Conclusion: Windows Server 2022 MPIO is built-in and takes effect without a reboot.
  • Apply To: XS3324D / XF2026D / XF3126D.
  • References: XEVO Software Manual.

Critical Notes:

  • RECOMMENDATION: Use Windows Server 2022 Multipath I/O rather than the QSAN MPIO driver.
