OceanDisk 1500/1600
Huawei OceanDisk 1500/1600 connects to diskless servers through NoF+ high-speed networks, enabling independent and elastic expansion of computing and storage resources. Designed for cloud and Internet data centers, OceanDisk devices can be combined into a fast and reliable shared storage pool to help customers improve resource utilization, while reducing cabinet space and device power consumption respectively by 40%. By utilizing the NoF+ high-speed network, simplified I/O paths, and the FlashLink® disk-controller collaboration algorithms, OceanDisk fully interoperates with third-party ecosystems and provide customers with composable storage capabilities. It delivers a maximum of 3.5 million IOPS and 70 GB/s bandwidth. Thanks to Huawei's continual investment in storage R&D innovation, OceanDisk provides high-performance shared storage capabilities, and cutting-edge technologies such as disk subhealth management and intelligent slow-disk optimization, ensuring stable performance of > 100 thousand disks in large-scale data centers and greatly simplifying O&M.
Green & Intensive management
Designed for the Diskless architecture, OceanDisk enables independent refresh and upgrade of compute and storage systems. Additionally, the utilization of new coding technologies enables scenario-specific lossless data reduction, while the 23+2 high-ratio EC algorithm engine improves resource usage. This results in a remarkable 40% reduction in both cabinet space and power consumption.
High performance
Hardware-software synergy technologies such as simplified I/O paths and FlashLink algorithms significantly increase the efficiency of data processing, reduce data read/write latency, and improve IOPS by 30%,thus enhancing upper-layer application performance.
Solid reliability
Multiple reliability features, such as the dual-controller A-A architecture, disk subhealth management and intelligent slow-disk optimization, ensure system-level reliability. These technologies make it easy to predict, oversee, and manage data disk faults, greatly simplifying O&M.
