Customers from media asset, high performance computing (HPC), and video surveillance scenarios have the following requirements for storage performance:
- Media asset scenario: With the development of 4K videos, customers require high-bandwidth and low-latency storage systems to support more layers of 4K video editing. Currently, non-linear editing is mainly performed on Mac OS X clients. A Mac OS X client can establish only one link with the storage cluster when it shares files using the NFS protocol. In addition, the prefetch conditions and I/O granularity of the Mac OS X client affects storage system performance.
- HPC scenario: The computing workload increases rapidly, requiring storage systems to provide sufficient bandwidth and stable performance to support rapid and massive data access. However, a Red Hat Enterprise Linux (RHEL) client can establish only one link with the storage cluster then it shares files using the NFS protocol. This restricts the data read/write amount of the storage system.
- Video surveillance scenario: In some scenarios, a large cluster may only serve a few clients. If the customer uses the native NFS protocol, the customer needs to create multiple sharing folders, and mount each sharing separately. It will take more action. And some applications cannot support such topology structure. Therefore, the usage of OceanStor 9000 has been restricted in this scenario.
The NFS protocol enhancement feature is a performance acceleration feature provided by OceanStor 9000. By configuring multiple network ports and installing NFS protocol optimization plug-in DFSClient on a client, concurrent connections can be established between a client and the storage system, thereby increasing the access bandwidth. Cache optimization is enabled on the Mac OS X client for improved access performance to adapt to 4K video editing in the media assets scenario.
describes the benefits provided by the NFS protocol enhancement feature.
| Benefit | Description |
|---|---|
In the media asset scenario, a single Mac OS X client can edit more layers of HD and UHD videos. | The NFS protocol enhancement feature enables the establishment of multiple links between a Mac OS X client and the storage system and optimizes client cache, significantly increasing read/write bandwidth of the client and shortening system latency. |
In the HPC scenario, a single RHEL client can have high read/write bandwidth. | The NFS protocol enhancement feature allows multiple links to be established between an RHEL client and the storage system and balances link loads, obviously improving the read/write bandwidth of the client and data transmission speed. |
In the video surveillance scenario, a Centos client can connect to more OceanStor 9000 nodes than to other scenarios. | The NFS protocol enhancement feature helps to create multiple links between the Centos client and the storage system, making most of the cluster capability. |
