I wrote wrong number, can just 8 vcpu to tenant
I checked datasheet, it is indicate r4600 can alloc 12 vcpu to tenant
but, when I checked that on gui, can alloc 8 vcpu to tenant
this device can alloc 12vcpu to all of tenant, but can't alloc 12vcpu to one tenant
so, I thought datasheet wrong
"If you purchased F5 rSeries r5000/r10000 systems and your rSeries appliances are connected to Cisco Nexus switches over 10-Gb or 25-Gb links, F5 recommends that you delay taking down the interfaces until you are able to download and install F5OS 1.3.2. F5OS 1.3.2 is not yet available, but you can contact F5 Support to get early access to the software if your scenario fits this description.
The 10-Gb and 25-Gb interfaces on F5 rSeries 5000 and 10000 systems may fail to establish links with Cisco Nexus 9000, 7000, or 5000 series switches. When this issue occurs, the network links either cannot be established or are suspended, resulting in no network connectivity between the rSeries system and the Cisco Nexus switch. In some cases, the link does not come up after a system shutdown or restart or after an interface shutdown.
This issue occurs when all of the following conditions are met:
The network link fails to establish, resulting in no network connectivity between the rSeries system and the Cisco Nexus switch.
As a result of this issue, you may encounter the following symptoms:
Note: This symptom is more likely to occur after upgrading to F5OS-A 1.3.1.
