DB size of the benchmark is about 800GB NEC Express core to host SQL Server. App servers are scale-out could be consolidated on few high end machines like DL980 or spread out on lower cost servers. Transactions/sec 5203 tps –business transactions. SQL Server transactions are much lower as they bundle multiple biz trans in single database tran. Clustering used for high availability. Log Shipping for Disaster Recovery. Repl is used in some deployments as way of reporting
