Best Practices for Exchange 2010 on Hyper-V
This document is available on Sunday by Microsoft is useful not only in cases of Exchange but as in any other project of virtualization with Hyper-V.
The document focuses on best practices for implementing Exchange 2010 on Hyper-V but additionally explains the technologies involved and because of the recommendation.
For example, explains each type of disk that Hyper-V supports (DAS, iSCSI, eSATA, etc.) and consider how best to be used and recommendations as meaning more than one network card in case of iSCSI virtual disks, fixed performance versus dynamic, etc.
But as the document is focused on Exchange, I found some very interesting recommendations, mainly the summary that he presents with items:
- Snapshots, differencing disks/delta
- Virtual processor/physical processor core ratios greater than 2: 1
- Applications running on the root virtual machine (excluding antivirus, backup, management software, and so on).
The middle of the document to front it is describing an example scenario and show the calculations involved for the client load and how would the sizing, including DAG and recommendations about how to use.
In short, essential read !!!!!!
