RDMA Configuration Steps

1. Block-Level Configuration Example
   • Login to iSER:

     # iscsiadm -m discovery -t st -p <Target_IP>
     # iscsiadm -m node -p <Target_IP> -o update -n iface.transport_name -v iser
     # iscsiadm -m node -p <Target_IP> -l
     

   • Logout from iSER:

     # iscsiadm -m node -p <Target_IP> -u

   • Check iSER Mode:

     # iscsiadm -m session

   • Add iSER Path to Increase Performance (Ensure Linux MPIO is configured):

     # iscsiadm -m session -r 2 -o new

2. File-Level Configuration Example (RoCE)
   • The current firmware version supports NFS RDMA.
   • Check NFS Export:

     # showmount -e 172.22.110.58

     Export list for 172.22.110.58:

     # /Pool-1/volume1/nfs *

   • Mount NFS Export with RDMA:

     # sudo mount -o rdma,port=20049 172.22.110.58:/Pool-1/volume1/nfs /mnt/nfs

Note:

NFS RDMA is available on port 20049.
