Features

Self-built NAS V.S. Conventional NAS

Alibaba Cloud NAS has many advantages over a self-built NAS on the cloud and conventional NAS products.

Overview Overview Alibaba Cloud Network Attached Storage (NAS) On-cloud Self-built NAS Conventional NAS
Reliability 99.999999999% data reliability Poor reliability. Data may be lost during data synchronization between master and slave nodes. 99.9%-99.99% data reliability
Availability No Single-Point-Of-Failure. 99.9% availability. SLA-guaranteed. Poor stability. Storage services become unavailable during server downtime. Single-Point-Of-Failure
Elastic Storage capacity is elastically scalable and may reach a maximum of several petabytes. Elastic resizing is not supported. Limited storage hardware capacity and long hardware upgrades
Throughput The throughput capacity is horizontally scalable and has a linear relationship with the storage volume. Low throughput which cannot be horizontally scaled. High-end NAS storage devices and a large volume of hardware are required.
Security Supports end-to-end permission management Only supports protocol-level permission management. Supports end-to-end permission management.
Simple Alibaba Cloud NAS is available for use immediately after simple creation, mount and other operations, and can be seamlessly integrated with other Alibaba Cloud products. Self-built NAS on the cloud requires investments in establishing and maintaining file servers, which can be a complicated process. Conventional NAS requires manual management of numerous resources including hardware, storage pools, file systems and protocols. It requires complicated and error-prone operations for a service to use the NAS.
Low costs Alibaba Cloud NAS supports both Pay-As-You-Go and Subscription storage packages and charges fees fully based on the storage volume, without other costs. Disks of self-built NAS on the cloud do not support Pay-As-You-Go payment options (you need to plan and pay for the maximum usage in advance). Additional server and maintenance costs are also required. Hardware is offered in whole sets regardless of the actual usage, and a large amount of hardware O&M costs are required.

Common Scenarios

Local and Cloud File Sharing

Challenge

Business system A is deployed in a local data center while business system B is deployed on the cloud. The business data generated by business system A needs to be uploaded to the cloud and used as the input for business system B. Every day 8 TB of data needs to be uploaded.

Solution

Standard NAS

The standard NAS provides elastic storage capacity based on the actual business need. The same NAS file system is mounted on both business system A and B to allow file sharing.

1 GB Leased Lines

The local data center is connected to Alibaba Cloud through 1 GB leased lines. The data generated by business system A can be uploaded to the cloud smoothly.

Benifits

The local data center no longer needs to upgrade storage capacity. Local data is elastically uploaded to and stored on the cloud.

Cloud Data Processing

Challenge

Because of the rapid business growth, the logs that are generated every day can fill up the 2 TB disk. Therefore, it is necessary to migrate disk data and expand disk capacity. Data migration causes service interruptions and makes it difficult to perform data analysis.

Solution

Performance NAS

Using the performance NAS, hundreds of Web servers can write the business logs into the shared file system without capacity limits. The same file system is mounted on multiple data analysis clusters to perform dynamic analysis.

Benifits

Log migration is no longer needed.

Dynamic data analysis is supported. The client can obtain the results of data analysis in 10 minutes, instead of waiting 24 hours.

Cloud-based NLE System

Challenge

The news station needs to publish current news and simplify the processes of video recording, editing, and uploading to improve efficiency.

Solution

NAS Plus Smart Cache

The NAS Plus Smart Cache provides a maximum throughput of 160 Gbit/s and allows 16 graphic workstations (GWSs) to work simultaneously. Each GWS can support editing 20 tracks of 4K videos at a time.

Graphic Workstation

Graphic Workstation provides professional video editing and processing capability. Each GWS can combine with professional NLE software to edit 20 tracks of 4K videos at a time and reaches a throughput of 10 Gbit/s.

Benifits

The cloud-based NLE system simplifies the video production process and enables news videos to be published within an hour. The cloud resources are billed per usage. This reduces the TCO by 60%.

High Performance Website

Challenge

As the business keeps growing, tens of millions of small files such as ../../images, audio files, and logs need to be transmitted through the mobile app. The number of daily active users has exceeded one million and is estimated to reach ten million in the next six months. The business requires disaster recovery across multiple zones and regions.

Solution

NAS Plus Extreme IO

NAS Plus Extreme IO is based on RDMA and NVMe SSD, and provides stable read and write ability that maintains 1M IOPS and a latency of 500 µs.

NAS disaster recovery

Provides a disaster recovery service across multiple zones and regions.

Benifits

Tens of millions of small files can be smoothly uploaded or downloaded every day. Achieves high availability and disaster recovery through asynchronous data replication.

DNA Sequencing

Challenge

DNA sequencing involves the explosive growth of demands for cloud resources. The system needs to reduce the time of each individual sequencing run from 5 hours to 2 hours or less and process more than 1 PB of data in each individual project.

Solution

Cloud Parallel File System

Cloud Parallel File System provides a maximum throughput of 1 Tbit/s and a capacity of 100 PB.This meets the storage needs of a large DNA sequencing program.

FPGA

FPGA provides computing power that is optimized for DNA sequencing.

Benifits

The business process now takes only 1.5 hours instead of 5 hours to finish. The cloud resources are only billed per usage, and the TCO is reduced by 70%.
