FastPath-related Options
NOTE: MSM or OEM applications must be running to flush file system buffers and take
snapshot when snapshot schedule expires. The system does not support snapshot
creation through BMC (sideband) and snapshot on volumes, which are used for VM
creation under virtualized environment. To flush the file system buffers, you should
interface with hypervisor.
Use the command in the following table to display the read and write configuration file.

Description
The command in this section is used to display information about the FastPath option.
MegaRAID FastPath is a high-performance IO accelerator for CacheCade - SSD Caching
software drive groups connected to a MegaRAID controller card. CacheCade - SSD
Caching 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 6-Gb/s MegaRAID SATA+SAS
controller.
The FastPath feature supports full optimization of CacheCade - SSD Caching software
and hard disk drive (HDD) virtual drive groups to deliver a three-fold improvement in
read and write IOPS compared to MegaRAID controllers not utilizing FastPath
technology. Also, FastPath software is faster and more cost-effective than current
flash-based adapter card solutions.
