Just a note that we use SUSE for our Ceph/Vmware system this is the general ceph docs for vmware/iscsi https://docs.ceph.com/docs/master/rbd/iscsi-initiator-esx/ this is the SUSE docs https://documentation.suse.com/ses/6/html/ses-all/cha-ceph-iscsi.html they differ I'll tell you what we've done and have been running for 3 years We had a bunch of pools - but condensed them down to just one This allows for more PGs - within the pool we have 4 RBDs (can have more or less) mapped to 4 vmware datastores We have two iscsi gateways - will add a third but for now we have 3 vmware hosts two 40 GB switches, 2 iscsi gateways, 4 luns = 16 paths (each lun has 4 paths) We can take a switch offline or a gateway - everything is multi-pathed and so stays up We have about 200 VMs from 12 GB to 20 TB each

You said "check the docs", but as far as I can tell, that info isnt in there. Or at least not in the logical place, such as the iscsi gateway setup pages, under https://docs.ceph.com/docs/master/rbd/iscsi-targets/ ----- Original Message ----- From: "Paul Emmerich" <paul.emmer...@croit.io> To: "Philip Brown" <pbr...@medata.com> Cc: "ceph-users" <ceph-users@lists.ceph.com> Sent: Thursday, December 5, 2019 11:08:23 AM Subject: Re: [ceph-users] best pool usage for vmware backing No, you obviously don't need multiple pools for load balancing. -- Paul Emmerich Looking for help with your Ceph cluster?
