FastPath
FastPath
is a feature that improves application performance by delivering high I/O per second (IOPs) for Solid State Drives (SSD). The Dell
PowerEdge RAID Controller (PERC) 10 series supports FastPath.
To enable
FastPath
on a virtual disk the Dell PowerEdge RAID Controller (PERC) 10 series cache policies need to 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), IO size,
and RAID type.
Disk roaming
Disk roaming is moving the physical disks from one cable connection or backplane slot to another on the same controller. The controller
automatically recognizes the relocated physical disks and logically places them in the virtual disks that are part of the disk group. You can
perform disk roaming only when the system is turned off.
CAUTION:
Do not attempt disk roaming during RAID level migration (RLM) or online capacity expansion (OCE). This causes loss
of the virtual disk.
Using disk roaming
Perform the following steps to use disk roaming:
1
Turn off the power to the system, physical disks, enclosures, and system components.
2
Disconnect power cables from the system.
3
Move the physical disks to desired positions on the backplane or the enclosure.
4
Perform a safety check. Make sure the physical disks are inserted properly.
5
Turn on the system.
The controller detects the RAID configuration from the configuration data on the physical disks.
