File Level Retention (FLR), also known as Write-Once, Read-Many (WORM), is available starting with PowerStoreOS 3.0. FLR prevents modification or deletion of locked files until a specific retention date. PowerStore supports both FLR Enterprise (FLR-E) and FLR Compliance (FLR-C) modes, which enable different degrees of file locking controls. FLR-C is designed for companies that need to comply with federal regulations and meets the requirements of SEC Rule 17a-4(f). For more information, see the Dell PowerStore: File Capabilities white paper.
