  • 1.  PowerVM SEA vs HNV configuration

    Posted 22 days ago

    What is the opinion about HNV (Hybrid Network Virtualization) with SR-IOV at Power11 S1122s? 

    Should we consider as standard Power Systems deployment?

    What are the limitations & benefits of HNV configuration over SEA (PowerVM)

    How do we monitor the HNV statistics over HMC

    Hello Muhammad,
    I also hesitated to use HNV for a long time.
    SEA was simple, easy to automate, and capable of LPM.
    With Power10/11, I almost exclusively use HNV.
    Automation is no longer an issue, and vNIC works excellently with LPM.
    The performance on networks above 10 Gbps is noticeable, and the CPU on the VIO servers is lower.
    It's important to plan for sizing and network architecture, as each network card only has a certain number of logical ports (e.g., 40, which is a lot, but sometimes not enough).

    Hi Faraz 

    Yes, you should consider HNV (Hybrid Network Virtualization) with SR-IOV for new Power11 S1122s deployments due to its performance benefits and improved LPM support over traditional SEA. However, it requires specific SR-IOV-capable hardware, which may limit its deployment scope compared to SEA, but vNIC is a key enabler for migration in HNV environments. 

    To monitor statistics, You cannot directly monitor HNV statistics on the HMC. Instead, you must use the HMC to configure the HNV adapter and then use the OS-level tools within the LPAR to monitor statistics.

    below are screen shot from LPAR HNV config
