In enterprises' Exchange email systems, IT organizations are doing utmost to resolve challenges resulted from increasing users and data. However, the inflexible infrastructure and isolated environment increase the complexity of email system management and email data protection. We need to consider the following problems in constructing and upgrading email systems of enterprises:
Huawei storage solution for Exchange mail systems combines the VMware platform and HUAWEI T series storage system. The solution is cost-effective and reliable, and is easy to manage.
To clarify the requirements of enterprises' Exchange email systems, we construct a typical network topology to explain how to quickly deploy Exchange applications by using HUAWEI T series storage systems. The solution adopts HUAWEI Tecal RH5485, a high-performance PC server delivering four data streams, as the vSphere virtual server, and uses HUAWEI OceanStor S5500T as the SAN storage system. Furthermore, the solution uses a double-site deployment plan and employs the Exchange 2010 DAG function. These qualities ensure the high performance of Exchange environment, the 24/7 continuity of Exchange applications, the database-level disaster recovery, and the failover among different sites.
The following figure shows the detailed networking diagram of the solution.
High Performance
The comprehensive solution is based on Huawei's mature and stable OceanStor T series storage system. The storage system's leading performance, high reliability, and intelligent resource management capability provide an efficient and reliable storage platform to Exchange email systems. S5500T is a typical example. Its outstanding performance and capacity expansion capability satisfy 20,000 mailbox users to receive and send 100 emails each every day.
High Expansion
OceanStor S5500T storage system has good scalability. Its performance and capacity increase linearly with the number of hard disks and it can support up to 288 disks. The expansion of storage system is convenient and can be achieved online.
High Reliability
The key parts and the data access paths of the storage system are fully redundant. Meanwhile, the solution supports many data protection methods, such as data coffer, disk precopy, RAID 5, and RAID 6. This high-reliability design ensures the 24/7 running of Exchange applications.
Close Integration with vSphere
OceanStor T series storage system has been authenticated by VMware vSphere 5. VAAI, SRM, and VASA. The storage system integrates with vSphere and has reduced bandwidth usage, server resource usage, and response time. Furthermore, the storage system effectively improves the availability and business continuity of virtualization platforms and provides an outstanding infrastructure platform to Exchange email systems for their fast deployment and stable service continuity.
Low TCO
High performance of HUAWEI OceanStor T series storage system and its integration with vSphere greatly enhance the capacity of virtualization platforms and reduce the investment on devices. Its intelligent resource management increases the usage of storage resources such as space and performance. Meanwhile, multiple energy-saving technologies can reduce the system power consumption by 30%.
HUAWEI Exchange email system storage solution has been widely used in various fields including governments, finance, power, and enterprises. It provides stable, reliable, and continuous storage and data protection service to users' IT business systems and improves the access efficiency and availability of Exchange email systems. The solution and VMware together achieve application-level disaster recovery for Exchange email systems. When a serious disaster happens, the solution provides a fast reconstruction and ensures the 7/24 running of the Exchange environment.
