Global Mailbox technical overview

The main components of Global Mailbox and the architecture for the components to work together

High availability in Global Mailbox
High availability in Global Mailbox is based on specific availability principles. There are some limitations to the high availability properties of Global Mailbox.
Mailboxes
Global Mailbox is a facility for creating a directory of mailboxes with submailboxes and hosting them across multiple data centers. Messages are created by Global Mailbox for applications (on behalf of trading partners, as application users) and stored in mailboxes.
Global Mailbox management tool
Global Mailbox administrators can manage mailboxes, messages, permissions, virtual roots, and event rules in the Global Mailbox management tool.
Administrative users
Administrative users in Sterling B2B Integrator (admins) are granted all permissions in Global Mailbox.
Event management
Global Mailbox administrators can create event rules to automatically initiate specific actions when a message is added to a Global Mailbox.
Functionality achieved by replication
Availability, performance, consistency, and durability of Global Mailbox are achieved by the replication feature.
Storage
In the Global Mailbox system, storage (file system) implementation is based on the concept of storage buckets. The buckets are containers (logical groups) in the file system, which are configured according to business requirements based on security and retention.
Scheduler
A scheduled job is a regularly performed task on the Global Mailbox system to automate routine operations and to maintain optimal system performance. You can modify the configuration of scheduled jobs with the schedulerConfigUtility script to meet your system requirements.
Migration
You can convert Sterling File Gateway partners and mailboxes to use Global Mailbox. You can create new accounts in Global Mailbox for Sterling B2B Integrator users and mailboxes and use adapters that are enabled for Global Mailbox. You cannot migrate users and mailboxes from one Global Mailbox system to another.
File transfer resumption
With file transfer resumptions, active file transfers that are interrupted, disrupted, or stopped can be resumed because the Global Mailbox saves data prior to the occurrence of errors.
Global Mailbox REST Services
The Global Mailbox implementation supports REST services to view and consume some resources in the Sterling B2B Integrator and Sterling File Gateway.
Performance considerations
The performance of your IBM® Global High Availability Mailbox system depends upon the interaction of the components, the communication paths between components, and the configuration settings. By monitoring your performance and tuning your system, you can balance file transfer speed with availability and protection from data loss. Your business requirements must be a consideration in designing and tuning performance.
Security considerations
Security for your Global Mailbox system must be planned and implemented as an integrated aspect of your deployment, and carefully monitored and administered to continue evolving to meet new risks as they form. By taking appropriate steps, your organization can minimize and mitigate threats.
