This technical white paper discusses Dell EMC’s solution for 10,000 Exchange mailboxes with 35GB mailbox size supporting up to 150 messages per day in a four-copy DAG. In this solution, the PowerEdge R740xd server with Dell EMC Storage MD1400 direct-attached storage (DAS) and 3.5-inch drives is configured for the Mailbox Server role.

Dell EMC PowerEdge R740xd is a 2-socket, 2U, rack server with a highly expandable memory, dense storage capacity and impressive I/O capabilities. The PowerEdge R740xd server can readily handle data-intensive applications that require large storage capacity and I/O performance such as email. It delivers the performance and availability required for mission-critical email services and is a great hardware building block for midsize to large organizations.

The internal RAID controller provides a range of RAID levels for improved storage reliability, while the optional CacheCade feature caches the most frequently accessed data, thus boosting database performance. The major features of the server or storage system are as follows.

  • Up to two Intel® Xeon® Scalable processors with up to 28 cores per processor.
  • 24 DDR4 DIMM slots that support RDIMM /LRDIMM, speeds up to 2666MHz, 3TB max.  Up to 12 NVDIMM, 192GB Max.
  • Up to 160TB Maximum Raw Internal Storage within front and mid bay
  • Choice of chassis configuration with sixteen 3.5-inch LFF disk drives, twenty-four 2.5-inch SFF disk drives, or eighteen 1.8-inch disk drives along with eight 3.5-inch LFF disk drives
  • Front loading drive bays plus four 2.5-inch SFF back-accessible drives
  • Integrated RAID support through PERC H730p, H740p, HBA330, Software RAID (SWRAID) S140 and External RAID support through PERC H840
  • Riser options with up to eight PCIe 3.0 expansion slots
  • Choice of NIC technologies
  • Dell EMC OpenManage portfolio of systems management solutions, including:

-   OpenManage Essentials console

-   iDRAC9 with Lifecycle Controller

 The Dell EMC Storage MD1400 direct-attached storage (DAS) enclosure with 12Gb SAS throughput is specifically engineered to work with the 14th generation of PowerEdge servers that use the newest line of PowerEdge RAID Controller 10 (PERC10) 12Gb SAS HBA cards. Scaling capacity built in the 14th generation of PowerEdge servers enables end-to-end 12Gb solutions with exceptional storage flexibility and IO performance for applications such as:

  • High-performance databases
  • Streaming digital media
  • Storage-intensive applications
