Hi,

Out of list you provided,

Following can impact SG managed LANs

â ¢ tcp_keepalive_interval=3600000
â ¢ tcp_keepalive_detached_interval=30000

I am not very sure of following
â ¢ tcp_text_in_resets=0

I advise you to confirm from HP support before you proceed these changes specially in PRD ENV.

Thanks Deepak for your Quick Response.

I really appreciated if you share with me any Technical document. I search a lot but didnâ t found any document related this topic on Google and HP also.

Thanks In advance
Khalid

Shalom,

The tuning on the two nodes should be similar or the same if possible. Why? Because the floating IP address in a cluster inherits the ndd characteristics of the parent NIC card.

You want to be sure whatever you do will let packages operate on all nodes.

Beyond that, I see little impact from any normal set of changes.
