JFYI: Today we get totaly stable setup Ceph + ESXi "without hacks" and this pass stress tests. 1. Don't try pass RBD directly to LIO, this setup are unstable 2. Instead of that, use Qemu + KVM (i use proxmox for that create VM) 3. Attach RBD to VM as VIRTIO-SCSI disk (must be exported by target_core_iblock) 4. Make a LIO Target in VM 4.1 Sync Iniciator (ESXi) and target (LIO) options (best change Target options) 4.2 You can enable almost all VAAI (also emulate_tpu=1, emulate_tpws=1) 4.3 For performance reason use noop on RBD disk in VM and set is_nonrot=1 (disable ESXi sheduller) 5. ESXi are "stupid" and have a problem with CAS on LIO (and some other storage vendors (google for info)), so for stable working without disconects of LUN set VMFS3.UseATSForHBOnVMFS5 to ZERO on All ESXi that use this lun. 6. Don't try make Target HA (not tested but i think you will catch problems with VMFS), you must do something like VM HA for that. This setup tested with latest ESXi and VMFS6.
