Pass-Thru FC and GbE2c Ethernet Blade Switch

Hi,

We have a HP BladeSystem c7000 Enclosure with five ProLiant BL480c G1, two GbE2c Layer 2/3 Ethernet Blade Switch and one HP 4Gb Fibre Channel Pass-thru Module for c-Class BladeSystem.
Each BL480c has one QLogic QMH2462 4Gb FC HBA with 2 ports and four NIC cards.

The enclosure maps two NIC ports to one GbE2x switch and the other two ports to the other switch. One port of HBA is mapped to the Pass-thru Module (interconnect bay5) but the other port is mapped to interconnect bay6 where there is no Pass-thru.

My doubt is if is possible to manually map ports to the GbE2x switch or Pass-thru Module.

I need to map the two ports of the HBA to the same Pass-thru module.

Thanks.

Sorry ...You can't change mappings, those are hardwired on the signal midplane.

Re: Pass-Thru FC and GbE2c Ethernet Blade Switch

You need another pass-through module.

By design, half of all signals are routed "west" on the midplane and the other half are routed "east." This is for redundancy. The midplane has no active components and therefore no electronics to fail, but in the event of a mechanical failure of the backplane, properly teamed devices will still be able to get out of the enclosure.

Thanks all.

The problem is that we don't have budget to buy another pass-thru module. However, we have two SAN switch and we wanted to connect one port of every HBA to every SAN switch to provide high availability at least in SAN switch.


Thanks again.
