DapuStor Haishen5 SSD Family

DapuStor Haishen5 Leverages Marvell’s Bravera SC5 Controllers

The new DapuStor drives are powered by Marvell’s Bravera SC5 family, some of the industry’s first SSD controllers that support the PCIe Gen5 interface. Designed for high performance, architecture flexibility, and efficiency (coupled with extensive security features), the new PCIe Gen5 controller line is optimized for organizations with critical requirements for scalable, containerized cloud storage infrastructure.

The controller also features throughput control in multi-tenant environments, edge expansion attestation and security, and helps to improve IO latency for real-time user responses.

DapuStor Haishen5 Performance

For performance, the Haishen5 offers double throughput compared to Gen4 enterprise SSDs, quoting sequential read and write speeds up to a blistering14GB/s (which is in line with KIOXIA’s CM7 PCIe Gen5 SSD) and 8GB/s, respectively.

4K random performance is expected to reach upwards of 2.8 million IOPS read and 600,000 write. DapuStor’s new Gen5 SSD also offers higher IOPS per watt for lower TCO and latency.
