EVA 4400 and CISCO MDS 9024

[JRoell]

Hi,

we have two EVA 4400 and two Cisco MDS 9024 per EVA. The Cisco SAN Switches Port 5 & 6 are configured as PortChannel (on all Switches). All LUNS on the first EVA are replicated with CA to the second EVA. In the controller -logs of both EVAs appears now (every 2 - 4 Minutes) a message that there are problems with the connection between the EVA Controllers (Quality of service ?) and that the Replication is impacted.

If I disable one of the ports in the portchannel on the Cisco SAN Switches the error message does not appear...

Any Ideas ?

Did you configure the switches according to the Implementation Guide?
""
- Vsan load balancing policy set to Src-ID/D-ID (vsan x loadbalancing src-dst-id)
- Enable in-order delivery (IOD) (in-order-guarantee)
- Write accelerator is set to off (no write-accelerator)

When using FCIP, the tcp send buffers must be set to 4096K on all FCIP Profiles at both source and destination sites. An exception is that low bandwidth applications must be set to 8192K (tcp send-buffer-size 8192)""

Hi Uwe,

can you post the link to the Implementation guide ?

Many Thanks.

It is on the CA manuals pages:
