ArcMail Archiving Appliances

ArcMail’s hardware platforms are state-of-the-art, designed to combine high performance and unmatched reliability in a smaller and more energy-efficient form factor. High performance processors, increased memory, and 2.5” enterprise-class hard drives in RAID configurations provide the speed and storage necessary to handle the increasing volume and variety of email, corporate social media postings, system files, and other data sources that today’s eDiscovery and regulatory compliance requirements demand.  

ArcMail Archiving Appliances are available in 1 TB, 2 TB, 3 TB, 4 TB, 6 TB, 8 TB, 12 TB, 16 TB, 24 TB, and 32 TB configurations.  Multiple appliances can be linked to form one logical unit with federated searches across all ArcMail appliances.


All outbound, inbound, and internal messages and attachments are directed to the ArcMail Defender. Our customer’s mail server makes a copy of every message – sending one to the archiver and one to the appropriate recipient(s). When data reaches the ArcMail archiving appliance, it is de-duplicated, indexed, compressed, and archived. Metadata and text data are extracted from all parts of each message, including header, body, and attachments.

When our customer needs to recover emails or attachments, the ArcMail platform’s industry-leading search and recovery functionality makes it quick and easy.  An authorized individual can locate emails and attachments using intuitive keywords with our basic or advanced search functionality, and restore or download them locally.
