Absolutely. Thank you both for your initial responses. I will definitely work through the documents Reagan already sent. Our R3 4.7x200 environment runs on a 2 note Windows 2003 R2 cluster environment. We use MS SQL 2005 as the current database engine. During normal operation, the database server will run on one node and the SAP central instance runs on the second node. We use HP DL385 Proliant servers. The servers are connected via fiber to the HP SAN. The only other solution to our SAP system is the integration with BSI TF9.
The ECC environment will be hosted by all new HP DL380 Proliant servers connected to a new SAN. We are still debating somewhat whether we should go all the way to Windows 2012 R2 or just go with Windows 2008 R2 for now. At this time we probably will only go to Windows 2008 R2 as we have limited go-live time. We will use MS SQL 2008 R2 as the database. Again, due to the short go-live time.
Let me know if I missed anything.
