Install Exchange 2010 on Hyper-V on HP 380G7

I'm planing to install Exchange 2010 on Hyper-V on HP DL380G7. Can anyone suggest the best practice to partition the disk ?

1. Create RAID-1 on two SCSI 300 Gb for root OS installation
2. Create RAID-1 on two SCCI 300 Gb for guest OS install (Window + Exchange)
3. Create RAID-5 on remaining SCSI 300 Gb for database  + OS.

Any  recommendation for this configuration ? Any other suggestion is welcome.

Thanks

1. Create RAID-1 on two drives for root OS
2. Create RAID-1/RAID-5 on all remaining drives for all VM's to reside.

As its virtualised there is little point it splitting into more that 1 raid for your VM's
There will always be debate as to using RAID1 or RAID5, personally I would go for RAID5.

How many total disks do you have? You dont say.

It is a HP DL380G7 with 600Gb x 8 SAS. It come with HP Smart Array P410i/256MB Controller.

I have seen some articles mentioning that it should split I/O for root, guest and database. That's why I split the RAID for different partition. Any comment ?
Can you give an idea of the numbers in terms of AD/Exchange users?

Currently we have 150 users / mailboxes.
I agree with Neilsr. Create RAID5 for VMs

So, just create RAID-1 x2 for the Root OS (Hyper-V Manager).

Then create all remainig disk into RAID-5 and put VM on it (ie. Exchange 2010 + database + log).


No need to consider I/O ?
Install the OS as RAID 1 and RAID 5 for the rest.
for 150 users and the specification you are talking about a single RAID5 array will be more than adiquate with no I/O issues.
That is, a single RAID5 array for everything else, the RAID1 for the OS/Hyper-V + Your RAID5.

How can I calculate the RAID-5 I/O to meet the requirement ? Under which level should I start to split my I/O ? In that case, how should I partition my disk / IO ?


Thanks again.
