SE Upgrades

The Controller allows you to pick up the number of SE-groups per Controller node.

seupgrade_fabric_pool_size:

This property allows the Controller to pickup number of SE groups per Controller to upgrade.

For instance, if seupgrade_fabric_pool_size is set to 3, three SE-groups are picked up per Controller, that means 9 SE groups across the cluster.

The default value of seupgrade_fabric_pool_size is 20. However, you can update this based on the requirement or the load.

seupgrade_copy_pool_size:

This parameter defines the number of simultaneous SE image downloads in a SEGroup. It is used to pace the SE downloads so that Controller network/ CPU bandwidth is a bounded operation. A value of zero will disable the pacing scheme and all the SE(s) in the SEGroup will attempt to download the image.

seupgrade_copy_pool_size = n, where ‘n’ is the number of SE within SE group will be picked for copy.

For instance, if seupgrade_copy_pool_size = 3, the three SE in a picked up SE group will be picked for copy.

The default value of seupgrade_copy_pool_size is 5. However, you can update this based on the requirement or the load.

The following are the steps to configure this:

  1. Configure the Controller properties.

  2. Set seupgrade_fabric_pool_size <number>.

  3. Set seupgrade_copy_pool_size <number>.

  4. Save.

[admin:ctrl]: > configure controller properties 
[admin:ctrl]: controllerproperties> seupgrade_fabric_pool_size 2
Overwriting the previously entered value for seupgrade_fabric_pool_size
[admin:ctrl]: controllerproperties> seupgrade_copy_pool_size 2
Overwriting the previously entered value for seupgrade_copy_pool_size
[admin:ctrl]: controllerproperties> save

[admin:ctrl]: > show controller properties |grep pool
