  • 1.  Hyperswap FlashSystem 5300 direct attach inter room

    Posted Wed May 29, 2024 09:17 AM

    Hello,

    I would like to implement a hyperswap configuration with 2  flashsystem 5300 i/o group  with direct attach inter-room between canisters.

    Does I need 4 FC port per canister for the inter-room connexions like this picture below or 2 FC ports per canister are sufficient?

    Thanks,

    Thierry

    In this way you have double-doble redundancy and double bandwidth. Basing on your data rate even 2 could be adequate.

    Yes, that is correct. There are such installations with other Flashsystems. And remember you need also a Quorum on a 3rd place connected to both sites.

    If your boxes is 5300, do you consider to use pbha instead of hyperswap?

    I never implemented Policy Based HA but as PBHA is the replacement technology for Hyperswap, I will try a PoC.

    Thank you Nezih

    Hi Thierry

     

    It is recommended to have four per canister. You can get away with two but it is not recommended.
