02351SGS

Which OceanStor systems is this 4TB disk unit compatible with?

This disk unit (BOM 02351SGS) is designed for the following OceanStor V5 storage systems:

• OceanStor 5600 V5
• OceanStor 5800 V5
• OceanStor 6800 V5

What are the key technical specifications of this disk unit?

The STLZD8NS4000 disk unit offers the following specifications:

• 4TB raw capacity
• 7.2K RPM rotational speed
• NL-SAS interface
• 3.5-inch form factor
• 520-byte sector size

What does the 520-byte sector size mean for this drive?

The 520-byte sector size indicates this is an enterprise-class disk formatted for storage arrays rather than standard 512-byte server drives. The additional bytes per sector are typically used for data integrity metadata, which helps the OceanStor controller detect and correct errors. This means the drive is intended for use inside the storage system and may not be directly readable in a standard PC or server slot.

Is this a SAS or NL-SAS drive, and what workloads suit it?

This is an NL-SAS (nearline SAS) drive, which combines a SAS interface with lower-cost, high-capacity rotating media. It is best suited for:

• Capacity-tier and archival storage
• Backup and restore targets
• Large-scale unstructured data and file sharing
• Cost-sensitive workloads that do not require high IOPS
