Step by Step creating DAG, Exchange 2010 PART#1

Filed under: General — telnet25 @ 6:01 pm

One of the most exciting future in Exchange 2010 no questions is the DAG (Database Availability Group).

Although the arguments of using JBOD and whatever RAID level is good for you, possible in Exchange 2010, I recommend consulting your vendor and see what will be their recommendations for implementing DAG for Enterprise network scenario, The Storage area vendors most likely will give you certain IOPS numbers with DAS or any similar storage device selection. I personally worked many times with NetAPP and I do know from experience they are ROCK solid appliances and if I would be implementing Exchange 2010 with DAG scenario I would  get their opinion by given numbers of users and usage of the mail servers to get their recommendation for the choice of DAS, SAN end RAID level needs to be used etc.

This example I am going to set  DAG for small company who has 200 users. Choosing RAID level also on the single server is totally up to you. In nutshell make sure you are redundant and you have configured the “Fastest” write and read RAID level as general rule. Server specs hasto be fallowed MS best practices guidelines.
