The Huawei OceanStor 9000 is a Big Data storage product. Applicable industries include broadcasting media, satellite mapping, genetic research, energy exploration, scientific research and education. With a distributed architecture, the OceanStor 9000 supports seamless scale-out from 3 to a maximum of 288 nodes. All nodes are symmetrically arranged in the OceanStor 9000. The OceanStor 9000 supports on-demand hitless scale-out, which increases capacity and performance linearly. The OceanStor 9000 offers up to 40 PB in a single file system. Such massive scalability helps maximally reduce your CAPEX and TCO while enabling the OceanStor 9000 to optimally adapt to your changing storage requirements.

The system contains 20 P Nodes. Each has 6 200GB SSDs and 19 900GB SAS disks. The WiseTier software dynamically recognizes hot files and migrates them between the SSDs and the SAS disks; hotspots are stored on the SSDs and colder files on the SAS disks. File data for a given file is striped across 9 P Nodes. Reed-Solomon erasure coding (8 + 1) is the default protection level for an OceanStor 9000 20-node system. +2 and +3 protection levels are also available.

Item No	Network Type	Number of Ports Used	Notes
1	10 Gigabit Ethernet	40	There are 2 10GE network ports used per OceanStor 9000 P Node for internal connection, with MTU size 9000.
2	10 Gigabit Ethernet	20	There is 1 10GE network port used per OceanStor 9000 P Node for external connection, with MTU size 1500.

Network Configuration Notes

All network interfaces were connected to the 10GE network switch(Huawei CE12800).

For each client, 4 10GE interfaces are bonded to one port, with MTU size 1500.

Processing Element Notes

Each of the OceanStor 9000 P Nodes has 2 physical processors, and each processor has 6 physical cores. Hyperthreading is enabled, yielding 24 hardware threads per node.

Memory Notes

Each OceanStor 9000 P Node has main memory for the operating system and filesystem data. A separate, NVDIMM module is used to provide stable storage for writes not yet committed to disk.

The NVDIMM in each OceanStor 9000 P Node stores and journals writes until they can be flushed to the disks. Each NVDIMM has a capacitor and 2GB flash. Data in the NVDIMM is flushed to flash using capacitor power (up to 25 seconds) when node power fails. Writes are ACKed to the client once they have been written and journaled in the NVDIMM. When the system comes back up after an outage, the journal in the NVDIMM flash is replayed. In the event of capacitor failure, data is no longer journaled in the NVDIMM, but is written to disks on a write-through basis.

The system under test consists of 20 2U OceanStor 9000 P Nodes. Each P Node has 3 10GE ports connected to a 10GE switch. One port is used for external connections; the other two are used internally.

Load Generator Configuration Notes

All clients are connected to the single filesystem /fs through all OceanStor 9000 P Nodes.

Each load-generating client hosts 1000 processes. The assignment of processes to network interfaces is done such that they are evenly divided across all network paths to the OceanStor 9000 P Nodes.
