To test whether the Amdahl LVS 4600 Storage System’s performance would degrade when I added workloads to other LUNs in the system, I used both single and multiple workloads. I set up a network to service a Microsoft SQL Server 7.0 application, a network to service a Microsoft Internet Information Services (IIS) 4.0 Web workload, and a network to service a file server. Table A details the performance test results.
