Hello Isilon experts,

I have an ISILON customer with two site configuration. As they have limited range of IP addresses, we can’t afford many IP pools, thus we have to use few SmartConnect zones.

The issue here is that the customer wants to make many SyncIQ policies in order partial failovers when needed. So I thought maybe I can use a unique SmartConnect Zone with many aliases and declare only the aliases on the DNS.

Below the suggested config:

SITE1		SITE2
SmartConnect Zone	site1.customer.com	SmartConnect Zone	site2.customer.com
SSIP	10.10.10.10	SSIP	10.20.10.10
Pool1	10.10.10.100 - 10.10.10.110	Pool1	10.20.10.100 - 10.20.10.110
AccessZone	NAS_Prod	AccessZone	NAS_Prod
Alias1	smbprod1.customer.com	Alias1	smbprod1.customer.com
Alias2	smbprod2.customer.com	Alias2	smbprod2.customer.com
Alias3	smbprod3.customer.com	Alias3	smbprod3.customer.com
Alias4	nfsprod1.customer.com	Alias4	nfsprod1.customer.com
Alias5	nfsprod2.customer.com	Alias5	nfsprod2.customer.com

So if I failover only the application running on nfsprod1.customer.com, I would only change the delegation for one Alias and keep the rest intact :

DNS Delegations
Before Failover		After Failover
Subzone	NS	Subzone	NS
smbprod1.customer.com	10.10.10.10	smbprod1.customer.com	10.10.10.10
smbprod2.customer.com	10.10.10.10	smbprod2.customer.com	10.10.10.10
smbprod3.customer.com	10.10.10.10	smbprod3.customer.com	10.10.10.10
nfsprod1.customer.com	10.10.10.10	nfsprod1.customer.com	10.20.10.10
nfsprod2.customer.com	10.10.10.10	nfsprod2.customer.com	10.10.10.10

What do you think about this config and do you see any limitations.

In addition to that, the customer is thinking about purchasing Superna Eyeglass license in the future; do you think of any drawbacks of this setup with Eyeglass way of managing failovers?

Thanks in advance

Regards
