  • 1.  Storage Direct attached Connectivity in SAP HANA Environment

    Posted 11 days ago

    Can any one advise on this:

     

    Does IBM support Direct Attached connectivity  with storage between 2x power servers with 4 vios each using dual port FCS i.e.

     

    1. Total no of VIOs 4 of POWER9
    2. Total no of IBM 16G FC adapter 4
    3. Total no of PORTS are 8
    4. VIOS v 3.1.3
    5. OS will be SUSE 15 SP5
    6. Storage is IBM V5010

     

    An early help will be appreciated.

    Hello Khurram,

    according to SSIC this combination basically seems to be supported, had checked this for FS5015 though.
    Note that with direct attachment the hosts cannot benefit from the storage-side NPIV for smooth node failover.

    Dear  Christian,

     

    Thanks for the reply, my another question is if we can use NPIV with this storage or revert back to old method of using VIOS VSCSI methodology?

    Hello Khurram,

     

    The NPIV remark is on storage side, not P-Series.

     

    No action required here, you can leave NPIV enabled, but there will be no added value of NPIV feature on storage :

    The advantage of having NPIV enabled on storage will only be visible when everything is connected via SAN switches.

     

    On P-Series (VIOS) you can do NPIV mapping as usual.

     

    Kind regards,

    V5010 has a limit of 8 fiber connections, each controller has 4 fiber ports.
    If the total number of ports on P9 is 8 or lower, you should be OK to use direct attached.
