| OS | Status | Community Notes | |----|--------|----------------| | | Works well | Based on Debian 12. Use nano /etc/modules to add hpsa . | | TrueNAS SCALE 24.x | Stable | Uses Debian-based Linux kernel; ZFS performance excellent with HBA mode on P440ar. | | XCP-ng 8.2 | Partial | Requires legacy BIOS boot; Citrix Hypervisor drivers work but no official XenTools. | | OpenBSD 7.4 | Unstable | Poor Smart Array support. Boot only from SATA AHCI mode. | | Rocky Linux 9 (RHEL 9 clone) | Untested by HPE, but runs | Kernel 5.14 works but you will see “hpsa: unsupported device” errors for some Gen9-specific RAID cards. | dl360 gen9 os support matrix
| Operating System | Status | Why Limited | |-----------------|--------|-------------| | | Uncertified | HPE has not validated this OS on Gen9. Use at your own risk. | | VMware ESXi 7.0.x | Legacy support only | VMware dropped Gen9 from HCL in ESXi 7.0 Update 3. | | Debian Linux | Community supported | No official HPE Smart Array drivers; use hpsa or mpt3sas in-kernel. | | Ubuntu LTS (20.04/22.04) | Limited | Ubuntu’s HWE kernel may drop C610 chipset support. Test thoroughly. | | FreeBSD 13.x | Not certified | Limited support for Smart Array controllers via ciss driver. | For virtualization, the Gen9 remains a popular choice
