1. Introduction The Astek A41606-ENC, D60-6A utilizes two Gen2 Serial Attached SCSI (SAS) expanders operating at 6Gbps with a sanitization algorithm that will sanitize up to 16 Self-Encrypting Drives (SED) that support the Cryptographic Erase Functions “Key Erase” (SBC-3, Sections 5.24/2/4) and “Block Erase” (SBC-3, Section 5.24.2.3). The A41606-ENC, D60-6A provide a dual ported storage enclosure based on Astek’s innovative SAS expander module, combined with a precision machined chassis, and a unique 'sled-less' disk mounting mechanism, these enclosures can hold up to sixteen 2.5” hard disks. The A41606-ENC provides two external SAS x4 wide-port input/output connections per expander, with each wide port supporting up to 24Gbps of I/O. Each port can be connected either to a host or another A41606-ENC, allowing system designers to cascade multiple enclosures to further increase the total available storage.

3. Cryptographic Erase The Astek A41606-ENC, D60-6A has a sanitization algorithm that will sanitize up to 16 SelfEncrypting Drives (SED) that support the Cryptographic Erase Functions “Key Erase”. Key Erase” (SBC-3, Sections 5.24/2/4 Block Erase” (SBC-3, Section 5.24.2.3 To erase data from drives connect to the CLI using the serial port with connection speed of 38400 and parameters 8-N-1. A password is needed; the default is “expander” The “santest” CLI command starts the erase process. It changes the encryption key stored in the crypto drive, thus effectively performing an instant erase then does a block erase of the drive.
