vHBA limits on M3 blade with VIC 1240

[subhishp]

Hello,

I have an UCS environment with FI 8324 and B200-M3 blades and VIC1240 cards. 

The VIC1240 data sheet says support for up to 255 virtual interfaces.

But the service profile association fails when there are more than 32 vHBA's created. 

Is there another limit that is restricting this or is there any licensing?

Thanks!

The UCS Configuration Limits guide that you pasted has these limits --

VIC Environment Configuration Limits

Static Virtual NICs per Host for Cisco UCS 6200 Series, Cisco UCS 6332 Series, and Cisco 6324 Fabric Interconnect

OS	vNICs	vHBAs	Max Combination of vNICs and vHBAs
Win 2008 SP2 and R2 SP1	20	16	12 Enics and 8 Fnics
Win 2012 and Win 2012 R2	20	16	12 Enics and 8 Fnics
Win 2016	20	16	12 Enics and 8 Fnics

Fibre Channel Environment Configuration Limits

Feature	Cisco UCS 6200 Series	Cisco UCS 6332 Series	Cisco UCS 6324
Virtual Fibre Channel interfaces per blade	16	16	16

Do these limits supersede the VIC capabilities (256 virtual interfaces)?

Currently, service profile association to a blade fails if we have more than 32 vHBA’s.

Thanks

Correct, this limit of 256 is a hardware / firmware limit; the installed OS however restricts this limit to a much lower number !
