  • 1.  DS8900F maximum distance between frames

    Posted 20 days ago

    Good morning everyone

    I have been told that current DS8900Fs don't need to have their expansion frame/s placed contiguously to the main one anymore, I am trying to find info about this, but no luck so far... can anyone confirm a future expansion frame can be placed separated from the principal frame, and what is the maximum supported distance between them?

    Thanks.

    Hi
    Max distance is 20m . See feature code 1341:
    https://www.ibm.com/docs/en/ds8900/9.4.0?topic=planning-hardware-features
    or in Installation Planning Guide:

    Introduction and Planning Guide below says "Feature code 1341 is the 20m cable to connect expansion frame."

    If Rack-2 is bolted to Rack-1, either left or right is fine.

     

    If Rack-2 is a distance away from Rack-1 (feature 1341), the Rack-2 cables connects to the

    Rack-1 20-meter extension cable couplers that are routed to, and inside, Rack-2..

     

    If DS8000 feature 1341 (20 meter E96 expansion frame PCIe3 cable set) is included with Rack-2.
