Novell NetWare 6 performance tuning guidelines for ProLiant servers There have been significant improvements in drive technology over the past decade. For instance, disk drive media speeds continue to increase. HP offers a wide range of drive spindle speeds in revolutions per minute (rpm). For instance, there are 10,000 and 15,000 rpm disk drives. The 15,000 rpm models are available in 18.2 GB and 36.4 GB with an average seek time of 3.8 ms, while the 10,000 rpm models are available in 18.2 GB, 36.4 GB, and 72.8 GB with an average seek time of 5.5 ms. It is therefore, advisable to choose the appropriate disk type with the highest speed your SCSI interface and controller can support. Similarly, as shown in table 2, HP has both Smart Array and Non Array controllers; all with different performance and capacity. The non-arrays such as the Integrated Drive Electronics (IDE) controllers and the low-end array controllers are typically embedded on the system board. table 2.
