4.2.2   

Drive IOPS Requirement by Workload 

The next step is to determine how approximately many drives can satisfy both the 
storage and the average IOPS requirement for each workload.

129 Desktops x10 Average IOPS = 1290 IOPS

1290 IOPS ÷ 150 IOPS per Disk = ~9

1200 IOPS ÷ 150 IOPS per Disk = ~8 

10k RPM SAS Drive Size

Average IOPS per Server 

70 Desktops x15 Average IOPS = 1050 IOPS 

# of 10k RPM SAS Drives 

1050 IOPS ÷ 150 IOPS per Disk = ~7 

10k RPM SAS Drive Size 

895 GB ÷ 7 = ~128GB 

 
The Standard Configuration was built using 16, 300GB 10K SAS to not only satisfy these 
calculations but to allow for more space for persistent and PVD desktop users as well as 
to support an increase in IOPS without a dramatic increase in the price of the system. 
These additional drives will also allow the array to be configured as RAID-10; thereby 
adding fault tolerance to the storage array, while minimizing performance degradation.

The Entry Level Configuration was built using eight 300GB 10K SAS to not only satisfy 

these calculations but to allow for more space for persistent and PVD desktop users as
