HP P6000 Continuous Access Implementation Guide (T3680-96431, August 2012)

C-series switch settings for the HP-FC protocol

NOTE: The following configuration must be used in an HP P6000 Continuous Access environment

for all Fibre Channel switches in the path from the source array to the destination array. This

includes FCIP routers that are connected to the fabric.

Execute the following commands to establish the required switch settings:

1. config terminal

2. (config)# in-order-guarantee (enable in-order delivery)

3. (config)# vsan database

4. (config-vsan-db)# vsan x loadbalancing src-dst-id (load balancing policy

set to Src-ID/D-ID)

5. (config-vsan-db)# end

6. copy running-config startup-config

7. config terminal

8. (config)# interface fcip (fcip #)

9. (config-if)# no write-accelerator (set write accelerator to off)

10. (config-if)# end

11. copy running-config startup-config

12. show fcip summary (review your settings)

• When using FCIP, the TCP send buffers must be set to 4,096 K on all FCIP profiles on both

the source and destination sites. One exception is a solution using a link less than OC3 (155

Mb/s), in which case buffers must be set to 8,192 K (tcp send-buffer-size 8192).

• In-order delivery guarantees that frames are delivered to the destination in the same order in

which they were sent by the source.

C-series switch settings for the HP SCSI-FCP protocol

NOTE: The HP SCSI-FCP protocol supports load balancing options src-dst-id or

src-dst-ox-id, and iod enabled or disabled. The best performance in a configuration with

multiple paths between source and destination is achieved using the load balancing option

src-dst-ox-id and iod disabled (no in-order-guarantee). Please review the Cisco switch

documentation for a detailed discussion of these settings.

Example

Example: The following commands set the switch settings for best performance.

1. config terminal

2. (config)# no in-order-guarantee (disable in-order delivery)
