vmware and VSA -> Raid
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.

ASKER
each server has 9 TB.

with bother servers I want to use VSA.
I want good performance but I will not loose so much space...

ASKER
which you would recommend for using VSA ?
RAID 10
ASKER
ok but here I loose 50% of the capacity.
Where do I set this on the host or on the VSA ?

ASKER
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 ?

when I have 9.2TB on each server. I have two hosts.
How much I have with VSA and Raid10 ?

What size of disks do you have in the server?
ASKER
I have 8 disks in each server with 1.2TB each.
Total in one server 8x 1.2TB
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)
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 ?

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)

ok thanks a lot
No problems, thanks.
Do you want MAXIMUM PERFORMANCE?
Or Best for Storage available?
