RecoverPoint Array Based Licensing and Multi-Site Replication

June 24, 2011

I’ve written in the past about the new licensing model for EMC RecoverPoint.  Overall the change is a welcome one in my book – simplifying licensing, any kind of licensing, is a good thing – I’m sure  Microsoft would disagree but oh well.  Something I recently ran into was with a client that needed to do cross replication between 3 sites using RecoverPoint/SE.  The situation created some questions around which RecoverPoint licenses I needed and more importantly how many of them. 

The environment was pretty straight forward, 3 EMC Celerra NS-480 arrays distributed across 3 cities with OC3 connections between them all.  All three of the sites were replicating using RecoverPoint CRR to another site basically doing cross replication.  Here’s a rough sketch of what we’re looking at:

 

 

 

 

 

 

 

 

 

 

 

 

 

After a few phone calls and e-mails the licensing solution basically looked like this:

Raleigh:

          2 x RPSE CRR Array Based Licenses

          4 RecoverPoint Appliances

Charlotte:

          2 x RPSE CRR Array Based Licenses

          4 RecoverPoint Appliances

Greensboro:

          2 x RPSE CRR Array Based Licenses

          4 RecoverPoint Appliances

There is still a 300TB limit per array for replication which for most shops in the commercial space is never going to be a problem.  That limit can be exceeded with special approval from EMC.  Without going into too much detail, the pricing of this configuration came out significantly less with the per array licensing model than if we were to try to do it on a per TB basis, not to mention it’s just simple – set it up and forget it.
