Through policy-driven management of email system mailboxes and archives, Netmail Archive can free up messaging server space and improve server performance. Netmail Archive also provides automated export of mail accounts and efficient release of licenses. It can also compress and store email in a place other than on a mail server.

In addition, Netmail Archive can be integrated with the following network storage systems:

Netmail Archive and Netmail Store

Netmail Archive integrates with Netmail Store software, allowing implementation of scalable, high-performance storage on any type of server hardware. Netmail Store is quickly and easily installed.

Netmail Store can be deployed in conjunction with Netmail Archive as a primary or secondary storage repository for static archived data, such as email messages and attachments. Netmail Archive communicates with Netmail Store via HTTP. The Netmail Archive server establishes an HTTP connection with the Netmail Store cluster and, after performing a handshake, sends a file to the Netmail Store cluster to be stored. In response to the file, Netmail Store sends a Content Address (CA) to Netmail Archive. The CA is an identifier that will allow Netmail Store to later retrieve the file. The Netmail Archive server stores the CA in the archive audit files, and the Index Server indexes this information.

Netmail Store uses a flat address space that can store billions of objects in one cluster. The cluster’s storage capacity can continue to be expanded by adding new server nodes with the Netmail Store software. Adding new capacity requires no provisioning or configuration, and can be done without taking the system out of service. Netmail Store ensures availability of content by creating multiple replicas of data, and it automatically replicates the content of a failed node to a healthy node.

With Netmail Store, you can choose the server hardware that meets your budget and performance needs because Netmail Store will run on any x86 platform. You can change your type of hardware server at any time.

Netmail Archive and NetApp

Netmail Archive’s flexibility lies in its ability to interface directly with the features and functionalities of the NetApp family of mass storage devices, which provide Netmail Archive with access from 1 to 96 TB of online accessible storage. Data is written to the device over standard GB Ethernet using a standard CIFS or NFS file access protocol to provide simplified secure access from one or multiple Netmail Archive servers.

The Netmail Archive server extracts and copies mail messages based on criteria, such as age, from the mail system, and places them in user-centric folders on the NetApp storage appliance in the form of XML files. Attachments are stored in native format within these user repositories. The Netmail Archive server can be configured to apply a retention date to each message it archives from the mail system. Netmail Archive then locks this file using a direct integration with the NetApp SNAPLOCK compliancy module, which turns the message file into a Read-Only, non-modifiable file format for the duration of the retention period, thus emulating a Write-Once-Read-Many (WORM) media type. Data is then indexed by the Netmail Archive server. Those indexes reside in the same data folders, but in a modifiable format so they can be continuously updated. Data is fully portable and may be copied off to other media for distribution, but the original data files cannot be modified or altered when using the SNAPLOCK compliancy option.

To further safeguard data, the NetApp storage appliance provides SNAPSHOT capabilities where the integrity of the data can be preserved through a virtual backup. To provide compliance for duplication of data criteria, mirroring options can be implemented for efficient replication of data between two NetApp storage units at different sites even over slower WAN links. Network Appliance storage units provide Netmail Archive with the functionality of NAS devices, but with the robustness and features of a full SAN, thus making available a single system for storage and access of archived data.

Netmail Archive and Hitachi Content Archive Platform

Netmail Archive offers direct integration with the Hitachi Content Archive Platform (HCAP) to fully leverage the powerful storage management of the HCAP system and offer tamper-proof WORM-based content storage.

Netmail Archive extracts and copies messages based on criteria, such as age, from the GroupWise or Exchange system, and then places the messages in user-centric folders on the HCAP device in the form of XML files. Through direct integration with the HCAP WORM capability, Netmail Archive locks the file into a Read-Only, non-modifiable file format for the duration of the retention period. Data is fully portable and may be copied to other media for distribution, but the original data files cannot be modified or altered when using the HCAP WORM and retention capabilities.
