Hi Philip, Part of it will be down to VFMS supporting features for ISCSI and then that is chained to specific ESXi and VM levels. Andrew Ferris Network & System Management UBC Centre for Heart & Lung Innovation St. Paul's Hospital, Vancouver http://www.hli.ubc.ca >>> Philip Brown <pbrown@xxxxxxxxxx> 6/24/2021 12:56 PM >>> I notice on https://docs.ceph.com/en/latest/rbd/iscsi-initiator-esx/ that it lists a requirement of "VMware ESX 6.5 or later using Virtual Machine compatibility 6.5 with VMFS 6." Could anyone enlighten me as to why this specific limit is in place? Officlaly knowing something like, "you have to use v6.5 or later, because X happens", would be very helpful to me when doing a writeup for potential deployment plans. -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown@xxxxxxxxxx| www.medata.com _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
