Hi
I am Running Exchange 2010 on Vm Machine,
Machine Profile:
16Gb Ram,4 Cpu,200 Gb Database,200 users.
Every Several months I Need To Migrate The Mailboxes To New Database,
The Old Database(After the mailboxes migration Process) always Get Error event 203,
Its Cyclic error That Occured every Serval Months To New Database.
I Am Backup Successfully The Database With Full Vss Every Day until the database get corrupted!,
The Biggest mailbox Is 10 Gb.
I Noticed That The Error Occured When The Store process Was On 17,000,000 kb/sec Persistent.
My Exchange Storage Is On Virtual San Hp Vsa.

The Strange Thing is I Have physical exchange 2010 servers in different company who serves 200 users as well,
has 200 gb database ,Less Ram Memory from my vm,
but The Big Difference is i didnt have any issues with the physical server like i have with the vm.

how can i be sure if my storage(virtual san,hp vsa) have poor issue when the exchange need to
work on high I/O ?
I Got The Event 203 When The Store Process Was On 17,000,000? is it normal?

Is My Storage Cause To My New Database Get Corrupted Because It Has Poor Performance?

thx

1. So it definitely sounds like the storage is causing issues so I would check event logs on the server to review critical application and system events
2. I would also check with HP to ensure you have the latest drivers, firmware updates etc

Thank You

How Can I Monitor/Test My Virtual San Environment To Ensure Its Function When Hosting Exchange 2010?
Can Jetstress 2010 Can Supply Me Answers To My Cyclic Problem?
Is there A Tool Or Configuration To Achieve Store Process On 17,000,000 b/Sec?

I would do three things

1. Look at the system event logs on your Exchange server

2. Look at the VMHost for disk errors

3. Look at the SAN via the mfg tools

4. Make sure all your drivers are up to date across the board
