MegaRAID FastPath is a high-performance IO accelerator for CacheCade software drive
groups connected to a MegaRAID controller card. CacheCade software has a read
performance advantage over HDDs and use less power. This feature dramatically
boosts storage subsystem bandwidth and overall transactional application
performance when used with a 6Gb/s MegaRAID SATA+SAS controller.
The FastPath feature supports full optimization of CacheCade software and hard disk
drive (HDD) virtual disk groups to deliver an improvement in read and write IOPS that is
three times greater than MegaRAID controllers not utilizing FastPath technology. Also,
the FastPath advanced software is faster and more cost-effective than current
flash-based adapter card solutions.
Perform the following steps to use the FastPath advanced software.
1. Select the Logical tab on the main menu screen for the Logical view.
2. Click a virtual drive icon in the left frame.
3. Click Virtual Drive>Set Virtual Drive Properties on the menu bar, as shown in
Figure 237.
