Configure the Microsoft Exchange 2013 Server Role Requirements Calculator
Overview
Download the Microsoft Exchange Workload modeling spreadsheet from Microsoft Exchange 2013 Server Role Requirements Calculator. Read the Microsoft Exchange Calculator Readme file for comprehensive guidance on using the calculator.
Cisco HyperFlex Sizer provides the BOM for the primary datacenter only. This section provides the parameters that should be configured on the Input Tab of the Microsoft Exchange Calculator. Customers who plan to deploy in multiple datacenters and stretch the Database Availability Group (DAG) must complete the input for the secondary datacenter under Site Resilience Configuration. Completing this input ensures that the primary datacenter Compute and Storage requirements are properly sized to handle all users in the event that the secondary datacenter is down.

High Availability Deployment |
Yes If a DAG is planned, ensure that High Availability Deployment is set to Yesand that the proper number of database copy instances are selected for each site. |
Tier-1 [2,3,4] User Mailbox Configuration
Ensure that the user mailbox tiers are set to the appropriate initial and maximum mailbox sizes. With HyperFlex, adding additional persistent tier disks or adding converged nodes to the cluster expands the usable storage on the cluster automatically. Adding additional databases, expanding the HyperFlex datastore, or expanding the Windows LUN where an online database is located, is instant and can occur without any downtime.

Backup Methodology field |
Backup Methodology can have a sizing impact. The recommended methodology is to utilize the Cisco HyperFlex native snapshot, along with a third-party backup application that will keep a copy of the backup off the cluster, typically in a backup repository. The following backup methodology options are available:
|
Backup Frequency field |
Weekly Full or Daily Incremental |
Backup/Truncation Failure Tolerance field |
3 |
Network Failure Tolerance (Days) field |
0 days |

Automatically Calculate Number of Exchange Database Volumes Required |
Yes If set to No, carefully size and ensure that enough Exchange Data Volumes are selected so that the databases fit on the server. If they do not fit, you will be unable to upload the spreadsheet into the Cisco HyperFlex Sizer, and a warning will appear on cell G216 on the Role Requirements tab. |
Number of AutoReseed Volumes per Server |
1 AutoReseed Volumes |
Server Configuration
The Microsoft Exchange Calculator is based on a particular baseline CPU. To properly calculate the megacycle to actual CPU consumption, enter both the number of vCPUs for the Microsoft Exchange Server VM in Processor Cores / Server, and the SPECint2006 Rate Value for the Cisco HyperFlex Server. For example values, refer to SPEC CINT2006 Result.
