Hi Experts,

when I have 3 servers , Dell720xd, and I want to use VSA, which raid is the best ?
Because on the hosts I have to setup the raid, and I can choose between 5,50,6,60 and so on.

You will need to select based on performance and storage size?

Do you want MAXIMUM PERFORMANCE?

Or Best for Storage available?

ok but here I loose 50% of the capacity.
Where do I set this on the host or on the VSA ?

on the hosts I can set more different virtual drives.
can I choose here just one drive with all capacity and later I can set more LUN´s with the VSA ?

I have 8 disks in each server with 1.2TB each.
Total in one server 8x 1.2TB

Okay, so configured as RAID 10

4.8TB (approx 4.5 usable for VSA, clustered between both Nodes)

Ok, for VSA I have to count both servers.
The capacity for VSA is 9.2*2/2 = 9.2.
With Raid10 I will have 4.8TB netto for data.
Right ?

if you have  8x 1.2TB disks on each server, configured as RAID 10, that's 4.5TB of usable storage, this is clustered between servers, so you still only have 4.5TB of storage to use in your cluster for VMs.

So you need to establish if 4.5TB SAN is large enough.

otherwise look at

RAID 5 7.8TB (approx)

RAID 6 7.2 TB (approx)

ok, that means in VSA I cannot setup LUN´s ?
That has to be done before?

1. Provision your hardware and storage and create RAID arrays.

1A. Install ESXi 5.5 and create datastores (4.5TB)

2. Install VSA using the 4.5TB datastore.

3. Then provision LUNs from VSA. (out of the chunk of 4.5TB)
