Thank you all 
My goal is to have an SSD based Ceph ( NVME + SSD) cluster so I need to consider performance as well as reliability
 ( although I do realize that a performant cluster that breaks my VMware is not ideal ;-))

It appears that NFS is the safe way to do it but will it be the bottleneck from performance perspective 

Anyone did a comparison between iSCSI and NFS  ?

Would network be a bottleneck ?

Many thanks

Steven

    Hi,
    we use PetaSAN for our VMWare-Cluster. It provides an
      webinterface for management and does clustered active-active
      ISCSI. For us the easy management was the point to choose this, so
      we need not to think about how to configure ISCSI...

      Hi,

        I need to design and build a storage platform that will be
          "consumed" mainly by VMWare 

        CEPH is my first choice 

        As far as I can see, there are 3 ways CEPH storage can be
          made available to VMWare 

        1. iSCSI
        2. NFS-Ganesha
        3. mounted rbd to a lInux NFS server

        Any suggestions / advice as to which one is better ( and
          why) as well as links to doumentation/best practices will be
          truly appreciated 

        Thanks
        Steven
