[IQUG] IQ_MPXNODE license requirements and DR strategy on IQ Multiplex primary and DR

IQ has a DR license which is cheaper than a primary license. However, you
can use a primary license if you prefer.

The Multiplex license is included in both, and is not something you need
separate.

Subject: [IQUG] IQ_MPXNODE license requirements and DR strategy on IQ
Multiplex primary and DR

 

Hi all,

 

Subjects:

1.       One DR strategy from an IQ Multiplex primary to a DR IQ Multiplex.
Each Multiplex has two nodes only.

2.       Does the second node of the DR Multiplex require one license of
"IQ_MPXNODE"?

 

Given an IQ Multiplex with two nodes at the primary, we will need one
license of "IQ_MPXNODE" on the second node; but both nodes need to have
"IQ_CORE" license. It's clear on the primary IQ Multiplex.  Do we have the
same requirement on the second node for the DR IQ Multiplex with  two nodes?

 

We, including Unix SAs and IQ DBAs" are thinking about taking database full
backups and transaction backups and restore them to the IQ Multiplex DR with
two nodes periodically throughout the days instead of depending on SAN Snap
Mirror replications.  It's not finalized yet.

 

I am raising two questions below:

1.       Is the DR strategy of using full backups and transaction backups
working from the primary IQ Multiplex to the DR IQ Multiplex?

2.       Will I need one more license of "IQ_MPXNODE" on the second node of
the DR IQ Multiplex even though the DR Multiplex should be offline most of
the time?

 

If I also need one license of "IQ_MPXNODE" on the second node of the DR IQ
Multiplex, it meant that I would need 2 licenses of "IQ_MPXNODE" in order to
set up a pair of IQ Multiplex primary and the DR.

 

Please advise on my two questions.  Thank you.

 

Regards,

Steve Shen
