Instructions
VRTX does not do RAID level migration or Capacity Expansion, while the "Reconstruct rate" can be set.
Under the Storage Controller settings for the SPERC 8 on the PowerEdge VRTX platform, is a setting called Reconstruct.
Historically, this setting was used to allocate a certain percentage of the RAID controllers resources to the RAID Level Migration (RLM) and Capacity Expansion (CE) operations.
- RLM is the act of converting one RAID level to another.
- CE is the act of increasing a virtual disk's capacity by adding more hard drives to the virtual disk set.
Note: The Reconstruct rate is different than the Rebuild rate. The Rebuild rate sets the amount of controller resources allocated to restoring a virtual disk to the optimal state following a hard drive failure.
This is a function of RLM, and CE is not supported on the VRTX platform.
