5 Core Advantages of 138 Enterprise Email

Advantage 1

Unlimited Capacity, Elastic Storage, Automatic Expansion

The 138 Enterprise Email system adopts a two-level storage structure, where email indexes record the location of emails, and email data has no direct association with storage devices. To add new storage space, you only need to mount the storage directory, adjust the directory storage weight, and then restart the storage MS service to complete the expansion, which has almost no impact on users.

Starting with 10G, it automatically expands as users' storage capacity increases, without affecting customers' normal use.

Advantage 2

Online Hot Backup and Online Repair of User Data

The 138 Enterprise Email system stores data by saving multiple emails in a single file, which greatly reduces the number of files and increases the speed of email backup and recovery. It also supports online hot backup of the user database. If the running database fails, the system automatically retrieves user information from the backup database to ensure that users can log in and send and receive emails.

138 Enterprise Email is also equipped with the AutoRepair function. When a user logs in, the system automatically checks user information; in certain special cases, such as the loss of a user's email index, the system can regenerate the email index to restore the mailbox to normal.

Advantage 3

Data Stream Processing Technology

The 138 Enterprise Email system adopts data stream processing technology, processing each block of data immediately upon transmission without waiting for the entire file to be transferred. This utilizes system memory more efficiently and supports ultra-large-scale user applications.

Advantage 4

Server Security Strategy

For multi-server deployment, 138 Enterprise Email adopts a ring backup method. This ring backup strategy provides data backup in an optimal form, ensuring system storage security and avoiding single points of failure. 138 Enterprise Email can also automatically determine the load among servers of the same type and intelligently route user requests, thereby reducing the burden on the servers.

Advantage 5

Automatic Recovery from Service Failures

The service modules of the 138 Enterprise Email system feature service monitoring. If a service program exits due to a failure, the system will automatically restart the service, save the service operation logs, and record the time for administrators to review.

In addition, each service module of 138 Enterprise Email includes a Heart-Beat synchronization information port. If a service processing module fails, the modules communicating with it will automatically stop data transmission to prevent performance degradation of the service caused by repeated connection attempts, ensuring the normal operation of other parts of the system and avoiding chain reactions caused by the failure. Data communication will automatically resume once the Heart-Beat information synchronization returns to norma
