Dell PowerEdge RAID Controller 11 User’s Guide PERC H755, H750, H355, and H350 Controller Series
FastPath
FastPath is a feature that improves application performance by delivering high I/O per second (IOPs) for solid-state drives (SSDs). The PERC 11 series of cards support FastPath.
To enable FastPath on a virtual disk, the cache policies of the RAID controller must be set to write-through and no read ahead. This enables FastPath to use the proper data path through the controller based on command (read/write), I/O size, and RAID type. For optimal solid-state drive performance, create virtual disks with strip size of 64 KB.
