Netapp + ESXi = Questions

Soon we will be setting up ESXi clusters on Netapp SANs.  What I'm having trouble wrapping my head around is exactly how to configure the Netapp side of things correctly.  I want all three ESXi hosts to access the same iSCSI lun, but where I'm falling short is how to configure that lun.

I setup a default LUN last year for two Hyper-V servers and while both servers could access and write to the LUN they could not see each others VM's.  Now that might be a Hyper-V limitation.. IDK exactly.  But having multiple hosts for failover won;t matter if I don;t setup the LUN correctly.

Can anyone lend a hand?

So.. I thought NFS was a choice between it and CIFS.. Are you recommending the creation of an NFS export with the hypervisors as root or read/write allowances?

NetApp recommends the use of NFS, as performance could be better.

Depending upon your licenses, you can run iSCSI, CIFS and NFS at the same time.

Ahh gotcha.  Ok so what'd be a best practice move here?  I have two shelves for virtualization.. so 28x144gb.  Create an Aggregate with 28 drives, then create FlexVol, then an NFS export with the hypervisors as read/write allowances correct?

Awesome.. now would creating an AGG with all disks negatively affect the spares?

You should really include a spare! (unless you have a disk on standby on the shelf!)

Ok cool deal.. I have 28 disks dedicate for VM storage so I created the agg with 24 disks, then a flexible volume and an NFS export.

Thanks Andrew, next time you are in rural Michigan let know and Ill buy you a beer!
