This technical white paper discusses Dell EMC’s solution for 10,000 Exchange mailboxes with 20GB mailbox size supporting up to 150 messages per day in a four-copy DAG. The solution uses the Dell EMC PowerEdge R740xd server for the Exchange mailbox server role and uses the internal storage of PowerEdge R740xd for storing the Exchange mailbox databases and transaction logs.
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, 192 GB Max.
