Are archive mailboxes going to be on the same mailstore as the primary mailboxes?
Will you be using single item recovery? Have you planned/projected your IOPS requirements on a per-user basis? How will the SAN disks be presented to the MB servers? FC? iSCSI? If iSCSI, do your NICs/switches/routers all support jumbo frames? How many copies of each database in the DAG? This configuration cries out for 4! What, if any, is the backup requirement? I don't see any inherently bad design choices. As you can see, a number of questions immediately appeared in my mind. Regards, Michael B.

The company i work for is looking at setting-up an Exchange 2010 environment for roughly 2000 users and additionnaly around 3000 Functionnal mailboxes, the total of mailboxes should soon evolve to 10 000. Mailbox size limit will be 2GB per user, archive per mailbox 5GB, deleted item retention of 30 days. First deployment for 5000 users will require at least 5000x2x5=50 TB of Data + Deleted Items Each mailbox server wil be presented with 80 TB of available space. Hardware has already been purchased and will consist of HP Blade Bl460c servers with 2 x Hex 2.93 CPUs, mailbox servers will have 48GB of RAM, Public Folders 12 GB, CAS/HUB servers 24GB. There will be 2 MBX servers in each site (so 4 in total spread accross 2 sites connected with a 10GB redundant link). There will also be 2x2 CAS/HUB servers (4 servers will participate in a CAS array) and 2 Public Folders servers. Storage design has been made and it is decided to use JBOD (P2000 SCSI SAN disks shipped with 2TB SATA disks 7.2K rpm), each server will be presented 42x2TB SAN disks (no raid) and these disks will be mounted as folders to the Operating System. So 42 folders for 42 databases. Each server will hold 10 active databases and 30 passive databases. There will a replication VLAN for DAG, a production VLAN (2 teamed Network cards on each server), a Backup VLAN (1 NIC on each server) and an administration VLAN. We have not yet tested this setup but i was hoping in regards to this figures if you guys could eventually point out some evident bad design issues if any.
