Introduction

Introduction

This section describes the background, definition, and benefits of the NFS protocol enhancement feature.

Background

Customers from media asset and high performance computing (HPC) 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.
NOTE:
  • 4K videos: ultra high resolution (UHD) videos (generally, 3840×2160 or 4096×2160)
  • Layers: the number of materials that can be read concurrently during video editing Videos played on TVs are synthesis of multiple layers of pictures. More layers lead to more diversified video content and require much higher read/write bandwidth.

To address the challenges, OceanStor 9000 introduces the NFS protocol enhancement feature to reconstruct the NFS protocol implementation of the clients. With the new feature, the clients can work with OceanStor 9000 better and maximize the storage system performance.

Definition

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 the client and the storage system, thereby increasing the access bandwidth. Cache optimization is enabled on Mac OS X clients for improved access performance to adapt to 4K video editing in media scenarios.

Benefits

Table 12-1 describes the benefits provided by the NFS protocol enhancement feature.

Table 12-1  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.
