Does anyone know if its possible to use the e0m interfaces on each controller of a FAS2240-2 for active/active configuration? I am basically just setting up this filer and is not in production yet. I want to setup the interfaces in the following way for resiliency/redundancy:
Controller A & B
e0a & e0d = vif0 (CIFS and in-band management of the filer)
e0b & e0d = vif1 (iSCSI access for VMware)
e0m = HA traffic
Please let me know if I'm totally off track or if I'm going in the right direction. The vifs are going to be terminating on LACP interface pairs on a Juniper switch.

In HA configuration, HA traffic is done internally if "one box" HA
e0M can be used for hardware assist mechanism and management
it's a combo port you also have SP (for out of band management)
Your LAN config is an option yes
Depending your Juniper configuration and possibilities, an alternative configuration would be: one VIF including 4 LAN port and create on that VIF 2 VLAN for CIFS and iSCSI

Thanks RICCO thats helpful. So e0m doesnt come into it when configuring the HA pair. If I setup the vif for iSCSI should I definately use an MTU size of 9000? Aparently jumbo frames aids in better IOPS from VMware to LUNs on the filer.

E0M is management port - out of band network.
FAS2240-2 has a build cluster and no need to explicitly configure it.
When configuring the ifgrp use the partner name not the IP's. Specify every interface with partner but not to aliases.

Well,it's a good broad topic. jumbo frame or not
many colleagues who tested this, do not found a significant increase in performance
You can configure the options ,if you want, you have to set MTU9000 on physical switch + vmkernel + FAS

Yea I've read alot of documentation on it. Just trying to do the best possible set-up for this FAS. We are using Juniper EX3300 switches for the ESX and storage. Storage is seperated by vlans and I have setup link aggregated groups of 2 interfaces i.e vif1 (e0b, e0c)(LACP) connects to a LAG (link aggregated group) on the juniper. The LAG on the juniper is set as LACP in active mode. Was a bit shaky on this part as normally with a LAG in Juniper one side is active and one side is passive. I'll see if it works tomorrow.
