During the planning stage for the CTERA Edge Filer, contact support regardless of whether the installation is a new installation or an upgrade from an existing installation.
End users who are familiar with a given folder structure and shares, as well as a given permission scheme, continue to see the same folder structure, shares, and permission scheme after migration to the CTERA Edge Filer. This enables the migration from a current file system to a CTERA Edge Filer without the need to apply any structural changes such as flattening the folder structure or simplifying the permissions scheme.
File and folder access continue to be available following the migration in the same way they were in the original file system. Access, after the migration, is through SMB, provided by the CTERA Edge Filer. Users continue to access the files and folders through standard client computers; for example, using Windows File Explorer or macOS Finder.
The following file server features are fully supported by CTERA Edge Filer and are copied to CTERA Edge Filer as part of the migration:
- ACL files/folder share permissions.
- Nested sharing.
- ACL emulation to allow files and folders management via standard SMB protocol.
- Shares can be mounted to users via standard administrator tools:
- DFS Management
- Group Policy (GPO)
- Other tools based on Net use
Use CTERA Migrate, which is accessed from the CTERA Edge Filer user interface, to create the corresponding shares in the CTERA Portal and sync them down to the CTERA Edge Filer.
CPU and RAM Recommendations
The normal edge filer usage is memory and network intensive and not CPU intensive. The edge filer is installed with 4 vCPUs. Increasing the number of vCPUs allocated for the edge filer should take the usage in to account.
CTERA recommends the following vCPU and RAM minimum requirements:
- The number vCPUs is the license number/4. For example, an edge filer with an EV32 license should start with 8 vCPUs.
- The amount of RAM is the license number/2. For example, an edge filer with an EV32 license should start with 16GB RAM.
The above are minimum recommendations which should be increased dependent on the specific usage.
