VMAX zoning best practices
I do want to know the zoning best practices for VMAX, like is it minimum 2 FAs should be contained in a zone or even 1FA with 1 initiator is also okay ?
like imagine like i have fabA and fabB with hbaA ,FA1, FA2 connected to FabA and hbaB ,FA3, FA4 connected to FabB. here have to create zoneA and ZoneB like here the basic zoning would be a zoneA with hbaA and FA1 and zoneB with hbaB and FA3 as its members, what is the best practice do we need to have like 2 FAs atleast for VMAX to brocade or any switch zoning?

here is a list of FAs on my 1 engine VMAX (you don't see H ports on my Vmax because they are in use by SRDF):
what i have done is this. Each switch fabric has even FAs and odd FAs. For example one fabric A i have FAs 7E0 and 8E0, on fabric B i have 7G0 and 8G1. Then on VMAX i create a port group that consists of 4 FAs. When you zone your host, hba1 will be zoned to FA 7E0/8E0 and hba2 will be zoned to FA 7G0/8G1. Take a look at this thread as well

As long as the two FAs are on different CPUs, you gain performance capability by adding more FA CPUs.

I want know here, what is the advantage of connecting two FAs to the same HBA ?

i addition it creates more paths in the OS ..thus more queue to drive i/o through.

still all the I/O should go through the same HBA right ?

Yes, typically the HBAs can do many more IOPs than the FA.

what ? Is that true ? Then why is an FA so much more expensive and you can get an HBA for let's say 1000 dollar or so. Or less.

Hi
In symmetrix all the paths are active - active so they will share the load and balance in all the paths.
in CLARiiON all the paths are active-passive .

In addition to the potential performance benefit the path to storage through the second FA provides high-availability in the event of an FA failure.

with ALUA on clariion the active/passive is not a limitation any more AFAIK. So if each port on SPA was running with 80MBs before the change , then now both controllers are running and 4 ports read 40MBs . So you can see the load is better balanced as far as pathe are considered. ALUA starts from flare 28(?)

are you cosidering around 4500 IOPS as the limit on the FA(such 3a[0-1],...3d[0-1] ) side? How much that differs dmx3/4 versus vmax?
