02352DHF

What is the BOM 02352DHF and which systems does it support?

This is a 7.68TB SAS Encryption Disk Unit (2.5-inch) specifically designed for Huawei OceanStor 5300 V5 and 5500 V5 storage systems. It carries the BOM number 02352DHF.

What are the key technical specifications of this drive?

Key specifications include:

• Capacity: 7.68 TB (raw)
• Interface: 12Gbps SAS
• Form Factor: 2.5-inch
• Encryption: Built-in SAS encryption (SED)
• Sector Size: 520 bytes (fixed)
• Model Suffix: STLZC6SSD7680

What does the "sectorsize-520" mean and why is it important?

This drive uses a fixed 520-byte sector size, which is commonly required in enterprise SAN and block-level storage environments. It enables additional metadata protection and is essential for applications that rely on T10 PI (Data Integrity Field) to ensure end-to-end data consistency.

Is this drive hot-swappable and does it support encryption in RAID configurations?

Yes, it is a hot-swappable 2.5-inch SAS unit. The built-in SED encryption works at the drive level, so it remains fully functional in RAID 0, 1, 5, 6, or 10 configurations managed by the OceanStor controller. Telecomate confirms that the encryption keys are managed via the storage system's security interface.
