# Edge Filer Deployment

The NAS modernization and ROB0 use cases require one or more edge filers connected to a portal.

**To deploy an edge filer:**

1. Install the edge filer:  

AWS: [7.12.x](/v1/docs/aws-12-1-1-1), [7.13.x](/v1/docs/aws-12-1-1-1-1).  

Azure: [7.12.x](/v1/docs/azure-13-1-1-1), [7.13.x](/v1/docs/azure-13-1-1-1-1).  

ESXi: [7.12.x](/v1/docs/esxi-11-1-1-1), [7.13.x](/v1/docs/esxi-11-1-1-1-1).  

Hyper-V: [7.12.x](/v1/docs/hyper-v-12-1-1-1), [7.13.x](/v1/docs/hyper-v-12-1-1-1-1).  

KVM: [7.12.x](/v1/docs/openstack-6-1-1-1), [7.13.x](/v1/docs/openstack-6-1-1-1-).  

Nutanix AHV: [7.12.x](/v1/docs/nutanix-ahv-9-1-1-1), [7.13.x](/v1/docsnutanix-ahv-9-1-1-1-1).  

Proxmox: [7.12.x](/v1/docs/proxmox), [7.13.x](/v1/docs/proxmox-2).  

Red Hat OpenShift: [7.12.x](/v1/docs/red-hat-openshift-1), [7.13.x](/v1/docs/ed-hat-openshift-2).  

Scale Computing HyperCore: [7.12.x](/v1/docs/cale-computing-hypercore-1-1), [7.13.x](/v1/docs/iscale-computing-hypercore-1-1-1).
2. Setup the edge filer: [7.12.x](/v1/docs/initial-ctera-edge-filer-setup-5-1-1-1), [7.13.x](/v1/docs/initial-ctera-edge-filer-setup-5-1-1-1-1), which includes connecting to the portal and configuring the storage.
3. Add the edge filer to a zone in the portal: [7.12.x](/v1/docs/adding-the-edge-filer-to-a-zone-in-the-portal-1), [7.13.x](/v1/docs/adding-the-edge-filer-to-a-zone-in-the-portal).
4. Load a Certificate: [7.12.x](/v1/docs/loading-a-trusted-ca-certificate-to-a-ctera-edge-filer-5-1-1-1), [7.13.x](/v1/docs/loading-a-trusted-ca-certificate-to-a-ctera-edge-filer-5-1-1-1-1).
5. If you are migrating data from a legacy file server:
  1. Change the eviction policy to enable eviction immediately after upload to the Portal.
    1. Log in to the edge filer user interface as an administrator.
    2. Select any option in the navigation menu (for example, **System > Firmware**).
    3. In the address bar of your browser, delete the string that appears at the end of the URL, after `config/` (for example, `firmware` if you clicked **System > Firmware** in the previous step) and type `cli` in its place.  

For example, change `https://192.168.28.214/admingui/main.html#/config/firmware` to `https://192.168.28.214/admingui/main.html#/config/cli`
    4. Press **Enter**.  

The **CLI** page is displayed.
    5. Run the following commands:  

`set /config/cloudsync/evictorSettings/retentionPolicyInDays "0-dedup,0-disk"` to set retention policy to zero days so blocks are evicted right after upload.  

`set /config/cloudsync/cloudExtender/storageThresholdToEvictPercent 20` to increase eviction percentage so more space is freed during runs, for example from 10% to 20%.  

`set /config/cloudsync/cloudExtender/syncFoldersTrashRetentionDays 1` to reduce trash retention from the default 7 days down to 1 day. This ensures deleted data is cleared faster, but still gives you a recovery window.
  2. Migrate the data [7.12.x](/v1/docs/migrating-shares-3-1-1-1), [7.13.x](/v1/docs/migrating-shares-3-1-1-1-1).
  3. Reset the eviction policy.
    1. Select **Cloud Drive > Cloud Drive** in the navigation plane.
    2. Click **Suspend**.
    3. Access the **CLI** page.
    4. Run the following commands:  

`set /config/cloudsync/evictorSettings/retentionPolicyInDays "NULL"`  

`set /config/cloudsync/cloudExtender/storageThresholdToEvictPercent 10`  

`set /config/cloudsync/cloudExtender/syncFoldersTrashRetentionDays 7`
    5. Select **Cloud Drive > Cloud Drive** in the navigation plane.
    6. Click **Unsuspend**.
6. Configure the edge filer for the following:
  - Enable Deduplication.
  - Enable Ransomware Protect.
  - Enable antivirus protection.
  - Set SMB audit logging.

Repeat steps **1-4** and then step **6** for every edge filer that you deploy. The edge filer content will sync with the data on the portal that you migrated in step **5**.
