iSCSI & Server LAN Traffic in Same Trunk Port

[michaelgitonga]

Hi,

I plan to use a Cisco UCS Rack mountable C200 server with a dual port PCIe card with TOE iSCSI. Is it acceptable to:

• To use just one dual port PCIe card for both iSCSI storage traffic and server LAN traffic - separated by VLANs? - With the ports connected two upstream swtches (for redundancy) and the switch ports configured as Trunks for both iSCSI & data VLANs??
  
• To use 1GE TOE iSCSI ports instead of 10GE TOE iSCSI ports
  
• To use a TOE iSCSI port for server data VLAN traffic??

I forgot to add that I'm using VMware Esxi 5 hypervisor.

Yes doable. Also you can mark iSCSI with cos 2 and 9000 MTU with certain badwidth gaurantee for your iSCSI traffic and rest stays in default queue.

class-map type qos iSCSI-qos-class

     match cos 2

policy-map type qos iSCSI-qos-policy

     class iSCSI-qos-class

          set qos-group 2

     class class-default

          set qos-group 0

class-map type queuing iSCSI-queuing-class

     match qos-group 2

policy-map type queueing iSCSI-queuing-policy

     class type queuing iSCSI-queuing-class

          bandwidth percent 30

     class type queuing class-default

          bandwidth percent 70

class-map type network-qos iSCSI-network-class

     match qos-group 2

policy-map type network-qos iSCSI-network-policy

     class type network-qos iSCSI-network-class

          mtu 9216

     class type network-qos iSCSI-network-class

          mtu 1500

system qos

     service-policy type qos input iSCSI-qos-policy

     service-policy type queueing output iSCSI-queuing-policy

     service-policy type network-qos iSCSI-network-policy
