Raid-5 vs. Raid-10 on ESXi 4.0?

[GITS]

Hi guys,

I'm new to the VMWare communities. I'm building a host server with ESXi 4.0 version. I don't know if i should build the server with a Raid-5 or Raid-10. Do you guys have any suggestion? Which raid work best for ESXi 4.0 ? I have a PE 2950, 8GB RAM, 4x 300 GB HD. Can you please help me on this. Thanks!!

i personaly would use Raid 5 you will get more useable space (900gb Vs 600) but i think there is abit more overheard vs Raid10

It really depends on what you are going to store on the disks. ESXi itself is fine with RAID 1 since it does barely produce any load. What matters, are the VMs residing on the datastore. You should consider the same factors, as you would with physical system, for example seperating database files from logs etc. However, if your VMs are only low loaded (which I actually assume since you seem to run a non-clusted ESX environment) you should be fine with one big lun which might as well be RAID5. If you need more performance RAID 10 would be the better choice, of course. VMware recommends not storing more than 15 VMs on the same LUN btw.

Kind Regards,

it depends on the fact if you are looking for speed or size. size -> raid 5, speed -> raid 10.
