Setting The Reconstruct Rate
Does my controller support this feature? See Supported Features.
The Set Reconstruct Rate task changes the amount of system resources dedicated for the reconstruct task.
The reconstruct task recreates the virtual disk after you have changed the RAID level or recongured the virtual disk. The
reconstruct rate, congurable between 0% and 100%, represents the percentage of the system resources dedicated for running the
reconstruct task. At 0%, the reconstruct has the lowest priority for the controller, takes maximum time to complete, and has least
impact to system performance. A reconstruct rate of 0% does not mean that the reconstruct is stopped or paused.
At 100%, the reconstruct is the highest priority for the controller, the reconstruct time is minimized, and has most impact to system
performance.

Setting The Redundant Path Conguration
Does my Controller Support This Feature? See Supported Features.
Redundant path is supported only on external PERC cards that use rmware version 6.1 and later. A redundant path internal to the
system is not supported. MD1xxx enclosures are supported.
For redundant paths, the enclosure must be in the Unied mode however specic port connections are not required. A connection
from either controller ports to either EMM In ports creates the redundant path as long as two cables are used. But, Redundant Path
continues to appear in the eld even as the redundant path is removed. The redundant path ceases to appear only when it is cleared
in the storage management.
In a daisy-chain scenario, more than one enclosure can be connected to a controller in a redundant path mode. You can connect up
to three MD1000 and MD1120 to a PERC 6/E controller in a daisy-chain enclosure. You can connect up to four MD1200 and MD1220
to a PERC H800 and PERC H810 controller in a daisy-chain enclosure. You can connect up to four MD1400 and MD1420 to a PERC
H830 controller and SAS 12 Gbps adapter in a daisy-chain enclosure. For an example of a daisy-chain conguration (for PERC 6/E
controller), see the following image:
