FSCT cleanup client /users 200/domain fsct.com

Cleanup required if

- All tests are done

- Changes in configuration (server, controller, clients, volumes or users)

- Test failed or aborted in the middle of a test run (leads to inconsistent file sets)

FSCT cleanup dc/clients CLI1,CLI2/users 200/domain fsct.com

Disclosure “best practice”

FSCT provides a summary of the results, but it does not include all the information about your specific configuration.If you choose to compile a report with your results, include enough information about your configuration to reproduce your testing. Always include the full configuration of the server, clients and controller:

System: Model, CPU architecture/type, clock, number of CPUs/cores, memory, bus speed, BIOS versionNetwork: Number of NICs, switches, NIC model/type, bus type, speed, firmware and driver versionDisk Subsystem: Type, model, fabric, spindles, drive speeds, HBA, firmware and driver versionOS: Version, edition, architecture, service packFSCT commandsEstimated cost of the system as configured

Common results should also include:Maximum throughput for HomeFolders workload (in scenarios per second)Maximum number of users for HomeFolders workloadCost/throughput for HomeFolders workload (in dollars per scenarios per second)Cost/maximum number of users for HomeFolders workload (in dollars per users without overload)

OS version is important! If a client is running Windows XP,

for instance, you get SMBv1, not SMBv2.
