Actually, the number is 12, that means I’m right. Shook From: Michael B.

And I think you are both right. The theoretical number available is 16. You can’t use 0 and you can’t use 15 (similar to the limitation in IP). That takes you down to 14. Then each controller uses one. With dual controllers, that takes you down to 12. Regards, Michael B.

Major +1 on Equallogic…contact me offlist is you have any specific questions. Also, watch out for the Dell arrays they both have a max number of connection limits (12, me thinks). So..if you have six servers with each with two connections for redundancy to the SAN, you’re done. No more SAN for you. Hope this helps… Shook From: Sean Martin [mailto:seanmarti...@gmail.com] Sent: Wednesday, July 28, 2010 5:48 PM To: MS-Exchange Admin Issues Subject: Re: Exchange 2010 DAG and backup options/recommendations. I would also look at the Dell/Equalogics. I keep hearing talk about them being one of the best performing iSCSI units out there, even compared to the big dogs like EMC and IBM. - Sean On Wed, Jul 28, 2010 at 12:30 PM, Pfefferkorn, Pete (pfeffepe) <pfeff...@ucmail.uc.edu<mailto:pfeff...@ucmail.uc.edu>> wrote: We were looking at going with Dells Powervault MD3200’s andMD1200’s.

Who is your storage provider? I just attended an EMC presentation at the Netherlands Hotel in downtown Cinci for 2010, DAGs, and storage. Your storage provider SHOULD have a solution.

Basically we will have 14,000 users and will allow users to go up to 4 gig mailboxes. We will have 4 backends distributed between 2 on-site buildings for redundancy (power/network). We will also be deploying a DAG configuration with 2 copies per database. We are talking a ton of storage and the question keeps arising about backups. I’ve heard with the DAG deployment, a backup system isn’t really required because of the database replication, but my mind keeps going back to the possibility of database corruption. Total data to be backed up could be 192 terabytes, so it’s a large amount of data. I was wondering what other large shops are using for that type of data. Comments on backup strategies for 2010?
