I need urgent info regarding what units need to be purchased in order to implement a storage environment using the Storwize V3700 units.
We are getting conflicting information with regards to the amount of expansion units we will need to setup our SAN system. What we want to have is as follows;
2x Host servers – running VMWare
Fibre connectivity between the hosts and the controller,would we require a switch between the hosts and the controller?
1x Storwize V3700 Controller unit – populate this unit with 24 x 600Gb 15K 2.5” HDD’s (used for SQL DB’s)
1x Storwize V3700 Expansion unit – populate this unit with 12 x 2Tb/3Tb 7.2K 3.5” or 2.5” HDD’s (used for Image storage)
This will be configured to use RAID 10 . Is it advisable to configure the entire 24x 600Gb HDD’s into 1 single RAID 10 array or should we split it up into smaller array’s. We want the best performance possible from this unit. Is there a limit on the amount of HDD’s that can be configured in a RAID 10 using this system?
We have been getting conflicting information that we will need to have 3x expansion bays as the RAID is setup better by having to read in a top down arrangement across multiple expansion bays. This doesn’t seem right to me. If we go this route then I will end up having the following setup which seems a waste.

1x Storwize V3700 Expansion unit – populated with 12x 2Tb/3Tb HDD’s
Not to mention we will most probably need an additional cabinet.
Please advise urgently with concrete supporting info.
Thanking you,
