nodes are restarting anywhere in the cluster, use MaxDiskWriteSpeed . The minimum speed for disk writes by all LCPs and backup operations can be adjusted by setting MinDiskWriteSpeed . 

• MaxDiskWriteSpeedOwnRestart 

<img src='content_image/854306.jpg'>

Set the maximum rate for writing to disk, in bytes per second, by local checkpoints and backup operations while this data node is restarting. 

For setting the maximum rate of disk writes allowed while other data nodes are restarting, use MaxDiskWriteSpeedOtherNodeRestart . For setting the maximum rate of disk writes allowed when no data nodes are restarting anywhere in the cluster, use MaxDiskWriteSpeed . The minimum speed for disk writes by all LCPs and backup operations can be adjusted by setting MinDiskWriteSpeed . 

• MinDiskWriteSpeed 

<img src='content_image/854307.jpg'>

Set the minimum rate for writing to disk, in bytes per second, by local checkpoints and backup operations. 

The maximum rates of disk writes allowed for LCPs and backups under various conditions are adjustable using the parameters MaxDiskWriteSpeed , MaxDiskWriteSpeedOwnRestart , and MaxDiskWriteSpeedOtherNodeRestart . See the descriptions of these parameters for more information. 

• ArbitrationTimeout 

<img src='content_image/854315.jpg'>

This parameter specifies how long data nodes wait for a response from the arbitrator to an arbitration message. If this is exceeded, the network is assumed to have split. 

The default value is 7500 milliseconds (7.5 seconds).
