Hi,
we have a m1000e blade center with m630 blades.
Each of them is equipped with Integrated NIC: Intel Ethernet 10G 2P X520-k bNDC
the blade center chassis has two MXL switches in a stack. The iSCSI uplink ports are connected to ToR switch stack over LAG. The ToR stack consist of two Dell N4032F switches.
PS6210 storage array is connected to these ToR switches.
The MXL switches will have both LAN and iSCSI traffic, therefore I was looking into option to allow DCB.
Are there any steps to allow iSCSI over DCB?
Does this NIC support iSCSI priority TLVs at all?
PS:
I didn't find Intel cards in Dell Storage compatibility Matrix for iSCSI over DCB.
what is shown on MXL-stack port towards blade server:
