Object Storage

VMRack Object Storageis a massive unstructured data Object Storage service. Based on an advanced distributed storage architecture, it provides users with secure, stable, and low-cost scalable data storage solutions.

Unlike traditional file storage or server-attached block storage, VMRack Object Storage breaks the directory hierarchy limit of traditional file systems. It uses a flat "Object" structure for data management. Users do not need to worry about underlying storage media, data partitioning, or hardware expansion; they only need to manage files through a simple and intuitive Web management console. It enables data storage and sharing anytime, anywhere on the Internet, eliminating the need to master complex code or API configurations.

VMRack Object Storage aims to be the gateway to cloud computing.

Basic Concepts

Before using VMRack Object Storage, understanding the following basic concepts will help you better understand and use the service:

Bucket: A Bucket is a container for storing objects and is the "root folder" in a traditional file system. Every object must be stored in a specific Bucket. Buckets have globally unique names and exist in specific regions.
Object: The basic unit of data storage in Object Storage. An object contains the content of the file data and metadata. Unlike traditional file systems, objects do not have a hierarchical directory structure but are identified by a unique "Key".
Region: The physical location of the data center where the Bucket resides. Users need to select a region when creating a Bucket. It is usually recommended to choose a region closest to you or your main user group to reduce network latency and improve access speed. (Note: The billing standards for different regions may vary).
Access Control: VMRack provides bucket-level access control lists. You can set the storage bucket to "Private" to protect data security, or set it to "Public" to enable sharing on the Internet.

Storage Classes

VMRack offers three storage types to meet the business needs of different data access frequencies and help you optimize storage costs.

	High Performance	Standard	Low Frequency
Positioning	I/O intensive business design	Balance of high speed and cost	Designed for long-term infrequent access data
Underlying Media	NVMe SSD All-Flash	Enterprise HDD Cluster	Enterprise HDD (High Density)
Scenarios	High-concurrency databases Big data computing middleware AI model training data Real-time high-frequency logs	Website/App resource sources (Images/Video/JS) Dynamic website file hosting Content Distribution (CDN) Origin Enterprise Network Disk/File Sharing	Long-term archived logs Cold backups not accessed for over 30 days Medical/Surveillance video history
R/W Performance	Extreme Speed Microsecond latency, High IOPS	High Millisecond latency, High throughput stability	Standard No freeze required, millisecond response
Min Storage Duration	None	None	30 Days
Storage Fee	Higher rate (Performance priority)	Standard rate (Cost-performance choice)	Lower rate (Cost saving)

Features Summary

VMRack Object Storage provides simple and extensive data management and processing functions:

Module	Description
Bucket Management	Supports creating and deleting storage buckets via the Web console, and viewing the bucket's basic properties and usage statistics.
Object Management	Supports uploading, downloading, and deleting object files. Provides a file browser based on the Web, supporting operations like creating new folders and file retrieval.
Permission Management	Provides bucket-level permission control, supporting setting "Private", "Public", and other access permission levels to ensure data security.
Network Security	Supports HTTPS encrypted transmission; supports Referer hotlink protection settings to prevent data from being illegally quoted resulting in traffic loss.

Product Advantages

Extremely Simple

Zero Technical Threshold: Designed specifically for users who value efficiency. Provides a fully functional Web management console. Operations like upload, download, creating folders, and setting permissions can be completed by clicking and dragging, just like operating a local network disk.
Instant Availability: Files automatically generate access links after uploading, which can be directly used for web page display or link sharing.

Stable & Reliable

Multi-Redundancy Architecture: Adopts a distributed multi-replica redundancy strategy. Data is dispersed and stored on different physical nodes. Even if a single hardware device fails, the system can automatically switch to a data copy to ensure no data loss and uninterrupted service.
Top-tier Data Centers: Servers are deployed in Tier-3 standard high-grade data centers, with complete power guarantees and network redundancy capabilities, providing enterprise-level physical environment security for your data.
Arrears Protection Mechanism: Even if the account is in arrears, the system still provides you with a 30-day data retention period, giving you ample buffer time for renewal, avoiding data loss caused by momentary negligence.

Transparent & Ultimate Value

Refuse Hidden Costs: VMRack adheres to the "What You See Is What You Get" pricing principle. No data retrieval fees.
Granular Billing: Uses a Pay-As-You-Go model. Storage is calculated by "Day peak value", and traffic is settled by "Hour". Truly pay for what you use, rejecting resource waste.
Free Quota Support: To lower the user's startup cost, We provide each user with a free quota of 5GB standard storage and 10GB downstream traffic per month.

Elastic Expansion

Unlimited Capacity: Completely removes the storage capacity limit of hard disks. Storage space automatically expands elastically with the data written, without the need for advance procurement or pre-configuration of storage resources, easily coping with data growth from GB to PB levels.

Application Scenarios

Website Static Resource Hosting: Store static resources such as website images, CSS style sheets, and JavaScript scripts in a "Public" storage bucket, utilizing the high concurrency capability of Object Storage to share the pressure on the origin server and improve website loading speed and reduce bandwidth costs.
Personal & Enterprise Data Backup: Use VMRack Object Storage as an off-site backup warehouse. Whether it is photos and videos in personal computers, or database backup files and log files generated by enterprise servers, they can be safely stored in the cloud to prevent data disasters caused by local hardware failures.
Content Distribution & Sharing: When sending large files to customers or team members, you only need to upload the file to Object Storage and send the generated link to the other party to achieve fast downloading, replacing traditional email attachments or FTP transmission.

Usage Limits

To ensure the stability and service quality of the platform, the current version has the following limits:

Operation Method: Currently only supports management via the Web Console. Does not tentatively support API, SDK, or third-party S3 client connections.
File Size: The maximum size of a single file uploaded by the system is 20GB.
Cross-Region Mounting: Does not support directly mounting storage buckets as local disks for cloud servers, nor does it support cross-region mounting.
