IBM Power Ideas Portal

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Start by posting ideas and requests to this portal to enhance a Power product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas and add comments to ideas that matter most to you

  3. 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 Power teams 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.

Enabling "TRUE LOAD BALANCING" for SEAs in dual VIOS setup

Currently in a dual virtual I/O server setup with SEA load sharing configured, each SEA is configured with more than one underlying virtual trunk Ethernet adapter. During the handshaking phase b/w the virtual I/O servers for establishing load sharing, each of the SEA (priority=1 & priority=2) would own half of the number of trunk adapters and would start bridging the traffic for VLANs mentioned within. The distribution of trunk adapters b/w SEAs is all dynamic (understand that may even change during next managed system power recycle) with no manual control. On one hand this offers a touch less operation and on the other takes away the control an administrator would want to have over distribution of VLANs based on his understanding of bandwidth requirements / usage.

In a typical DC environment there would be couple of VLANs (production, backup, management, admin.....) Each of the VLAN would have different bandwidth requirements and overlapped bridging via same VIOS may result into limited network capability / resources, while the other VIOS might still carry enough unused bandwidth (as might be bridging only low bandwidth VLANs). While the name is load sharing, this may actually not result into true load sharing.

The enhancement requested is to allow an administrator to have control to create affinity for specific TRUNK adapter association with a VIOS, i.e non default control over VLAN distribution. The default behavior for load sharing may continue as is, for those who may not wish to leverage this new enhancement.

    Hi Team,
    It is been more than two month since this request was submitted but have received no response so far !

    Am engaged with another financial client at UK these days and facing the same query.

    Please treat a little promptly and respond / action.

    NOTE : This request defaulting into private category and am not able to request impacted client to vote for this and share their comment at it on the portal. Am sure this can not attract any external vote this way and request to please consider this accordingly

    Hi Team,
    As a part of my job role with IBM SYSTEMS Labs Services, I often get chance to interact with clients having significant POWER install base and often get to hear their feedback on our products and technologies.

    The current RFE, I have raised is based on the feedback received from Senior Administrator of an MNC bank. The raised request for enhancement is towards ensuring throughput truly balanced across network infrastructure and to make better usage of networking resources invested in.

    Not sure, if this is a little too early to check for on the status of the same.

    Please suggest / revert for any further required information on this.
