FreeNAS, a popular open-source network-attached storage (NAS) operating system, supports the use of solid-state drives (SSDs) as a write cache (ZIL) and read cache (L2ARC) to improve performance. Here’s how to add ZIL and L2ARC SSD devices in FreeNAS:<\/p>\n

    \n
  1. Connect the SSD devices to your FreeNAS system and ensure that they are recognized in the Storage > Disks menu.<\/li>\n
  2. Go to the Storage > Volumes menu and select the volume for which you want to add the SSD cache.<\/li>\n
  3. Click the Edit button and go to the Volume Settings tab.<\/li>\n
  4. Under the Cache section, select the checkbox for “Use cache disk” and choose the ZIL SSD from the drop-down menu. This will configure the SSD as a write cache.<\/li>\n
  5. If you also want to add a read cache, select the checkbox for “Use L2ARC” and choose the L2ARC SSD from the drop-down menu.<\/li>\n
  6. Click the Save button to apply the changes.<\/li>\n
  7. To verify that the cache drives are in use, you can go to the System > Tunables menu and look for the vfs.zfs.cache.size<\/code> and vfs.zfs.l2arc.headroom<\/code> tunables. The values should reflect the amount of cache that is being used by the system.<\/li>\n<\/ol>\n

    Note: Before adding cache drives, it’s recommended to backup important data as adding cache drives can cause data loss in the event of hardware failure. Additionally, it’s a good idea to verify that the SSDs are compatible with your FreeNAS system and have adequate capacity for your needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
