MSSQL and Exchange DB in the same aggregate ?

itebu

Hi,

Small question, is there any problem having 1 volume for MSSQL and another volume to host Exchange PF in the SAME aggregate ? We are using FC disks.

Sure you can, and we have many customers that do.

The bottom line is your SLA.  If you are not 100% Outlook cached mode, blips in latency (above 20ms) for the Exchange DB or (above 5-10ms) transaction logs will cause end users to have to wait (OWA/mobile), or cause an Outlook popup (online mode).

To prevent this, you want to understand your SQL IO, and size appropriately. (Don't run huge SQL batch jobs in the middle of the work day, etc).

FlexShare can be used to prioritize the Exchange volumes over the SQL ones.

Thanks,

Robert
