  • HIL/BMI users need to have access to ceph-public network (HIL admin operation), add it to their project/nodes/nics and configure an ip, ip is calculated as described below (user operations)
  • For client IPs use 192.168.32+Cnum.Unum mask, where Cnum is cage number and Unum is U number. Cage and U numbers are used in node mame - neu-1-21 means Cage 1, U 21 and the ip would be
  • Ssh access is by using FreeIpa accounts, nodes are accessible from BMI provision subnet (500) by name. Ssh to monitor nodes to get ceph.conf and admin keyring.
  • Please use ecrbd pool for rbd images to save disk space. To create an image using erasure coded pool for data storage use rbd create mynewrbdimage --data-pool ecrbd --size xxxG
  • Be careful with the number of placement groups if creating new pools

VPN range

Network connections

For 1 GB U number goes to the same port number.

For 10GB U1 goes to ports 1 and 2 on lower Brocade switch, U2 - ports 3,4 up to U20. U21 goes to ports 1,2 on upper switch and so on.
