02351SHL

Which storage systems support this 7.68TB SSD drive?

This drive is exclusively designed for Huawei OceanStor enterprise storage arrays. It is fully compatible with the following high-end rack-mounted models:

• OceanStor 18500 V5
• OceanStor 18800 V5

What are the detailed technical specifications of the 02351SHL disk?

The 02351SHL is a high-performance SAS SSD with enterprise-grade features. Its core technical parameters include:

• Raw capacity: 7.68 TB (usable capacity varies with RAID configuration)
• Interface: 12 Gb/s SAS (dual-port, full duplex)
• Form factor: 2.5-inch small form factor (SFF)
• Sector format: 520 bytes per sector (fixed, not user-configurable)
• Encryption: Built-in hardware-based data-at-rest encryption (SED)
• SSD type: High-endurance SAS SSD (HSSD) for mixed read/write workloads

What is the 520-byte sector size, and why does it matter for my system?

The 520-byte sector size is a non-standard format primarily used in enterprise SAN and hyper-converged environments. Unlike common 512-byte or 4K-native drives, this 520-byte layout reserves 8 extra bytes per sector for metadata and integrity tags (such as T10 PI/DIF). This enables end-to-end data protection and early error detection. However, you cannot reformat this drive to 512 or 4Kn sectors; it must remain 520-byte to work properly with OceanStor V5 controllers. Always verify that your storage pool and host OS drivers support 520-byte devices before deployment.

Is this drive hot-swappable, and what encryption standard does it use?

Yes, this 2.5-inch SAS SSD is fully hot-swappable and supports online insertion/removal without powering down the storage enclosure. The built-in encryption is a hardware-based Self-Encrypting Drive (SED) compliant with the TCG Enterprise standard. When used with the OceanStor V5 system, the encryption keys are managed by the array's built-in key management module, ensuring that all user data is automatically encrypted at rest with zero performance overhead. No external encryption software or host-side processing is required.
