High-density distributed scale-out storage
Huawei OceanStor Pacific 9546 Scale-Out Storage
Balanced scale-out storage for mass unstructured data, HPC and backup
The Huawei OceanStor Pacific 9546 is a high-density, balanced scale-out storage appliance. Its 4U chassis holds up to 60 3.5-inch drives and provides up to 1,440 TB of raw capacity, with Kunpeng 920 nodes, NVMe cache, multi-protocol access and erasure coding for HPC, big-data analytics and large-scale backup and archiving.
Key features
Fully symmetric scale-out
A distributed architecture adds nodes in a fully symmetric cluster, balancing performance and capacity automatically.
High-density 4U chassis
The 4U chassis holds up to 60 3.5-inch drives and provides up to 1,440 TB of raw capacity per chassis.
Multi-protocol access
NFS, SMB, POSIX, MPI-IO, HDFS and Amazon S3 are served from the same data set for HPC, analytics and backup workloads.
Kunpeng-powered nodes
Each node runs two Huawei Kunpeng 920 processors, up to 512 GB memory and palm-sized NVMe SSDs for caching.
Erasure coding
N+M erasure coding (M = 2, 3 or 4) protects data with automatic parallel reconstruction at up to 2 TB per hour.
Fast networking
10/25/100GE TCP/IP and RoCE, plus 100 Gbit/s EDR InfiniBand, support high-bandwidth and high-OPS clusters.
Typical use cases
High-performance computing
Dense, multi-protocol storage for HPC clusters using POSIX, MPI-IO and high-speed RoCE or InfiniBand.
Big-data analytics
HDFS and S3 access to large data repositories with NVMe cache for fast analytics.
Backup & archive
High-capacity 3.5-inch HDD storage with erasure coding, WORM and encryption for long-term data protection.
Dense scale-out storage for unstructured data
Unstructured data now drives most storage growth, and it demands a different design than traditional dual-controller arrays. The Pacific 9546 answers with a fully symmetric distributed architecture: nodes are added to a balanced cluster, capacity and performance grow together, and data is served through NFS, SMB, POSIX, MPI-IO, HDFS and S3 from the same data set.
Density is central to the design. A single 4U chassis holds up to 60 high-capacity 3.5-inch drives and provides as much as 1,440 TB of raw capacity, powered by two Kunpeng 920 processors, up to 512 GB memory and NVMe SSD cache per node. 10/25/100GE TCP/IP and RoCE, or 100 Gbit/s InfiniBand, provide the bandwidth these workloads need.
Resilience is built in rather than bolted on. N+M erasure coding protects data with less overhead than replication, and automatic parallel reconstruction reaches up to 2 TB per hour. Together with WORM, encryption, snapshots and the ability to tier with faster Pacific products, the 9546 gives HPC, analytics and backup teams a dense, economical scale-out platform.
