Test scenario To characterize its scalability, HP tested the HP ProLiant BL465c G7 server blade in 64- and 32-bit HP SBC environments when running a workload based on the User profile described above. Note: As recommended by HP for most applications, the FBWC was configured with 100% write for all testing. Use the BIOS to adjust the read/write ratio. Testing was initiated by running the particular workload with a group of 15 simulated users; start times were staggered to eliminate authe

Figure 4 shows normalized Perfmon values. Figure 4. There were no stopped sessions when 487 Heavy Users were logged on With 487 users active, there were no stopped sessions. The processor became saturated with approximately 500 users logged on, which coincided with the marked increase in processor queue length shown in Figure 3. The maximum number of users able to log on was 739, though approximately 2% of sessions had stopped. 12
