Get feedback from the IBM team to refine your idea
Help IBM prioritize your ideas and requests
The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.
Receive notification on the decision
Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.
Feasibility of multihome Management hosts to support different MTU on network.
We would like IBM to certify below solution for supporting differnet MTU with multiple network cards on Management hosts and different sets of compute hosts where one set of comput hosts has 1500MTU setup and another set of compute hosts has 9000MTU setup.
1> Master and Master candidate will have two different network interface on two different subnets. One network interface with have MTU set to 1500 and second interface will have MTU set to 9000. 2> One set of compute hosts will have MTU set to 1500 and will communicate with master hosts over network interface with 1500 MTU on master host. 3> Second set of compute hosts will have MTU set to 9000 and will communicate with master hosts over network interface with 9000 MTU on master. 4> Master host will have static route set to compute hosts with 9000 MTU on network interface with 9000 MTU. 5> For rest of servers over network, master host will use default route on network interface with 1500 MTU.
