Each of these three test points is critical in validating a storage subsystem for
a high performing, stable Exchange environment.
Together, these three tests help validate a storage subsystem for overall
high performance, stability, and an optimal Exchange environment.
Targeted customer profile
This solution is intended for small- and medium-sized businesses hosting 600
Exchange mailboxes. The configuration used for testing is as below:
• A single Exchange server.
• 600 users per server.
• 0.45 IOPs per user
• 1 storage group
• 200MB User Mailbox size
• Disk-to-Disk backup strategy.
The ESRP-Storage program focuses on storage solution testing to address
performance and reliability issues with storage design. However, storage is
not the only factor to take into consideration when designing a scale up
Exchange solution. Other factors which affect the server scalability are:
server processor utilization, server physical and virtual memory limitations,
resource requirements for other applications, directory and network service
latencies, network infrastructure limitations, replication and recovery
requirements, and client usage profiles. All these factors are beyond the
scope for ESRP-Storage. Therefore, the number of mailboxes hosted per
server as part of the tested configuration may not necessarily be viable for
some customer deployment.
