Messaging solutions have emerged as mission-critical applications, consuming a large part of many organizations’ IT budgets. The rich features in these applications have significantly changed the messaging requirements and needs of today’s information workers, from basic desktop e-mail access to collaboration from anywhere with any device. This has resulted in ever increasing demand on server and storage systems in terms of capability, capacity and bandwidth.

Increasingly, the cost of power and cooling systems is impacting IT budgets. From public cloud to on-premise deployments, the energy expenditure for IT infrastructure impacts the bottom line. To reduce the data center footprint, many organizations are looking for denser and more energy-efficient platforms from both a server and a storage perspective.

The primary approach to maximize rack density is form-factor reduction and server and storage integration. Advances in server technologies, both in terms of performance and power efficiency, have enabled denser, more powerful server platforms while reducing power consumption. As larger capacity and more energy-efficient disks have become available, a trend to integrate these disks within rack server platforms has taken hold. This aggregation of computing and storage enables a building block approach to fulfill the requirement from demanding messaging application workloads. The Dell PowerEdge R720xd server is an excellent example of the balance of computing and storage. This server takes the building block approach to the next level by reducing rack space requirements, while lowering powering and cooling requirements. The rack-optimized R720xd also reduces the number of enclosures to be managed, cabled and maintained.

To showcase the advantages offered by the PowerEdge R720xd, engineers at the Dell Global Solutions Engineering Lab conducted comparative studies of the PowerEdge R720xd vs. the PowerEdge R710 with Microsoft® Exchange 2010 solutions. These studies suggest significant improvements in the data center footprint from reduction in rack space by up to 50 percent and in power consumption by up to 32 percent for the same number of Exchange 2010 mailboxes. Additionally, these studies suggest that the PowerEdge R720xd I/O subsystem is capable of supporting up to 20 percent more Exchange 2010 mailbox I/O operations than the PowerEdge R710 combined with the PowerVault™ MD1220 for the Exchange 2010 solution.
