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.
