Set L3 cache as the default for node pools

You can set L3 cache as the default, so that when new node pools are created, L3 cache is enabled automatically.

Before you begin

L3 cache is only effective on nodes that include SSDs. If none of your clusters have SSD storage, there is no need to enable L3 cache as the default.

Procedure

  1. Click File System > Storage Pools > SmartPools Settings.
    The Edit SmartPools Settings page appears.
  2. Under Local Storage Settings, click Use SSDs as L3 Cache by default for new node pools.
  3. Click Save Changes.

Results

As you add new nodes with SSDs to your cluster, and OneFS designates new node pools, these node pools automatically have L3 cache enabled. New node pools without SSDs do not have L3 cache enabled by default.
