FastPathFastPath
The FastPath feature is an intelligent I/O passthrough mechanism for Solid State Drive (SSD) arrays. This advanced software is an
optimized version of controller technology that can dramatically boost storage subsystem and overall application performance,
especially for applications that demonstrate high random read/write operation workloads.
FastPath is enabled for a logical drive when the logical drive is created with properties Direct IO, Write Through, and No Read Ahead.
The logical drive must be in an optimal state for FastPath to be enabled.
FastPath allows the following IO scenarios:
Read IOs to all RAID levels when IO size is less than or equal to the strip size.
Write IOs to RAID 0 when IO size is less than or equal to the strip size.
All IOs targeted to a single drive RAID 0.
Write IOs to RAID 1, 5, and 6 do not use FastPath.
