Hyper-V 2012 Datacenter - Multipath Failover Policy RRS feed

  • Domanda

  • Buonasera a tutti,

    Vi chiedo un consiglio per l' impostazione load balance policy MPIO su un Cluster Hyper-V 2012 Datacenter.

    Ho 4 volumi da 1.3TB configurati in SAN con il multipath del vendor NetApp -  DataOntap DSM 4.1.

    Posso assegnare le seguenti policy:

    Auto Assign Active/passive. An arbitrary path is used to access the virtual disk. A passive path takes over for the active path if the active path fails.
    Failover Only Active/passive. The path you specify is used to access the virtual disk. A passive path takes over for the active path if the active path fails.
    Round Robin Active/active. All paths are used to access the virtual disk, in round-robin order.
    Round Robin with Subset Active/active. The paths you specify are used to access the virtual disk, in round-robin order. A non-preferred path takes over for a preferred path if the preferred path fails.
    Least Weighted Paths Active/passive. The path with the lowest weight value is used to access the virtual disk.
    Least Queue Depth Active/active. All paths are used to access the virtual disk, in order of the available path with the smallest queue.

    La Policy di default è: "Least Queue Depth" ma vorrei modificare in "Round Robin with Subset" per modificare i path preferenziali scegliendo i due impostati nello zoning (hba0 e hba1, FabricA e FabricB).

    Leggevo su qualche blog che NetApp consiglia nelle best practice di impostare tale policy in VmWare ma non ho trovato nulla per Hyper-V.

    Che ne pensate?

    Grazie per il supporto.
