Huawei Secure Erase on RAID Controller

 Huawei RH1288v3 server is one of the model RAID controller built-in this features


Huawei secure erase uses Multi-pass overwrite (3x), which is a recommended Purge method suggested by NIST SP 800-88 Rev. 1. The current NIST SP 800-88 Rev. 1 guidelines state that a single-pass overwrite is generally sufficient for purging data on modern hard disk drives (HDDs). For flash-memory-based media like SSDs, device-specific commands or cryptographic erase are the recommended purge methods.
