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.
