NPIV and fcsX queue_depth on VIOS (physical) and LPAR (virtual) HBAs.

[w5000]

is it enough to set queue_depth for virtual HBAs on client LPAR only or also queue_depth for physical adapters which are used in background on VIOS should also have some higher queue_depth set before they are configured in "NPIV"?

are there any others physical HBA attributes to be adjusted on VIO Servers to avoind i/o bottlenecks on client LPARs?

the memory on VIO servers is enough (I calculated 300MB per single virtual HBA - recommendations I found were 140MB for each)


thanks in advance for any tips

of course I meant fcsX and fscsiX attributes - is it enough to tune only virtual fcs/fscsi on client LPAR or the same setting must also be set for physical HBA's devices on VIOS site (the ones which virtual ones are mapped to)
