Abstract: This research paper is directed at improving the Replication Overhead of Microsoft Exchange Mailbox Databases in a Database Availability Group for Mid-to-Large sized organizations while not compromising on the High Availability and resiliency of the email service. There are many aspects of a healthy Microsoft Exchange email landscape, yet the one factor which is often ignored is the number of Mailbox Database copies that are managed and maintained by an Organization. The larger an organization, the more complex the email environment, resulting in dependency on Hardware and constant stress due to increase in demand. Validating the Replication Threads for each Exchange Mailbox Server and reducing the number of Copies may be the solution until a new environment is commissioned that addresses the stress pain points. The primary goal of this research paper is to improve upon the reliability and stability of an enterprise email environment, which increases user productivity through improved system response and availability. Keywords: Replication Performance, Microsoft Exchange Database.
I. INTRODUCTION Microsoft Exchange Server is the most widely, if not the only, used email platform for mid-size to large organizations especially for the on-premises deployments. This paper provides an insight into the performance optimization for mid-tolarge scale deployments of Microsoft Exchange Server by utilizing the most optimal hardware configuration. Hardware in terms of CPU and Memory can either provide a consistent experience or negatively impact the email service if not appropriately planned and tested before production. This research paper aims to provide the most optimal hardware resources required for different on-premises deployments of Microsoft Exchange while not compromising on the High Availability aspect of Mailbox Databases in a Database Availability Group; it looks at one of the factors which is the number of Mailbox Database Copies on each Microsoft Exchange Server in a Database Availability Group. Client connectivity, such as RPC/HTTPS, MAPI and ActiveSync protocols, are not considered in this research. Microsoft provides Exchange Calculator and JetStress tool which is highly recommended to arrive at proper hardware (CPU, Memory, IOPS, and Disk Drives) prior to deploying a highly reliable and scalable Microsoft Exchange environment. These two critical components are not part of this research paper; yet the concept presented here looks at optimum performance based on the replication threads for each Mailbox Database.
