2tier or 3tier landscape for AS/400 ?

[Former Member]

Dear all,

My company is considering upgrade options for current AS/400 server. There are 2 options we are considering.

1.) Upgrade the existing box to a bigger capacity to have higher SAPS. Landscape remains 2tier.

2.) Change 2 tier to 3 tier and split the Application Server from the central instance. No upgrade for the current AS/400 server, but just add few more Application server to run in Wintel server.

Have been advised that AS/400 server has self-managed capability and it is not advisable to split to 3tier.

My questions

a.) Anyone out there who has successful story to share in implementing 3tier landscape with AS/400 server ?

b.) Any write-up about the difference in terms of performance between 2tier and 3tier landscape. Or even to share your experience.

Your advise and comment will be appreciated.

Thanks.
