Huawei OceanStor 100D – Product Brief

This document is no longer maintained as of 2024

Beginning with release 8.0 in 2019, Huawei OceanStor 100D is an object storage system with support for block and file access as well. Prior to 2020 the product was named FusionStorage. Before release 8.0, FusionStorage was a block storage system only. As an object storage system, OceanStor 100D has exabyte level scaling for capacity and a virtually unlimited numbers of objects. The system can scale from 3 to 4,096 nodes. The objects are distributed in a ring structure implementing the Chord protocol.

The Huawei OceanStor 100D system is offered as software or a complete system that uses ARM64 processors in Huawei servers. Earlier versions of OceanStor 100D came with x86 processors. Storage is a mixture of HDDs and SSDs where both SAS and NVMe SSDs are supported. Extensive features are supported both in object storage usage and in block storage use. Block storage features are similar if not identical to those used in OceanStor systems.

Data in the OceanStor 100D system is stored in OSD (object storage) format in blocks on attached storage devices. Load balancing and data distribution is performed by the system using a distributed hash table as part of the Chord protocol. The ring uses the distributed hash table with key-value pairs. The key format comes from a hash of the data and the object ID. The algorithm maps objects to a virtual key (node) spaces and routes access requests to the node owning the data. Each node will have a successor and predecessor to the next node. Data and node protection use Forward Error Correction information dispersal using Erasure Codes for N+2, N+3, or N+4 protection.

Block storage access is supported for iSCSI, SCSI, and InfiniBand access. Data is independent between objects and block storage. File access is supported through use of gateway devices such as Panzura, Veritas Access, and SoftNAS. In this case, files are stored as objects with access through gateways only.

Welcome

The vision behind everything in Futurum’s Custom Research practice is this: research should show you what is happening, what comes next, and what to do about it. It should be personal to each audience, easy for people to grasp, and structured so LLMs can reason over it accurately. And it should be fast and turnkey; you want answers now, not another project to carry for quarters.

Whether you are defining business, channel, or go-to-market strategy; evaluating vendors or justifying ROI; or commissioning research to fill an emerging market need, we have your back, with a program that answers your questions with the objectivity and credibility to drive real decisions.

To do it, we bring unmatched data to bear: Futurum research, surveys, and market projections; validated market feeds; ETR’s 15 years of insight from 10,000 technology decision-makers; G2’s buyer and user data; and what our analysts hear every day. Add leading primary collection, from AI-moderated voice interviews to surveys and analyst-led interviews, all turnkey, and every project comes out credible, nuanced, and actionable.

And we don’t just drop the results in your lap. For internal work, we provide analyst-led sessions, interactive dashboards, and a range of formats. For market-facing work, Futurum delivers turnkey activation and amplification that actually gets seen, by people and by LLMs, through our media and share of voice. This is research that moves decisions and markets.

We will meet you wherever you are, from a fast-turn brief to a multi-year program, and shape the work to your goals, timeline, and budget. The right program for your moment.

If any of this is useful, I would love to talk.
