Good news for Commvault customers – you can now purchase new licences much more cost-effectively

Up until late last year Commvault Simpana was licensed based on front-end data capacity, with the choice of three editions:

  • Data Protection Foundation (DBF) – includes file and virtualisation agents
  • Data Protection Advanced (DPA) – added Microsoft application agents and array snapshot management
  • Data Protection Enterprise (DPE) – added all other applications agents (i.e. Oracle and SAP)

These editions could not be mixed, therefore if you needed further capacity and you are currently using DPE, you would have to add more DPE (which could be quite expensive).

So what has changed?

  • DPA now includes all the features of DPE, excluding Ops Reporting – this makes the more costly DPE redundant in most cases
  • Virtual Machine agents can now be licensed per socket or per pack of 10 VMs – making VM backup typically much more cost-effective than using a capacity licence (please note that the entire cluster must be licensed)
  • Licence types can be mixed (i.e. DPF, DPA, DPE and VM agents) – this allows for a solution to be built as cost-effectively as possible (Simpana 9 SP9 or above required)

So what choices are available if more licences are required?

  • Assuming that Ops Manager is not required purchase a capacity licence of DPA (if application agents are required) and/or DPF (if just VMs and file system agents are required)
  • Convert all VM agents to use either per socket or per 10 VM pack licences, and utilise the existing DPE/DPA/DPF licences for non-VM backups and application agents

Let’s look at an example

A customer has a 100 TB licence of DPE and moving forward will need to protect 120 TB of data, with a mix as follows:

  • 20 TB of data requires application agents (increasing to 25 TB)
  • 20 TB of data requires file system/NDMP agents (increasing to 25 TB)
  • 60 TB of data requires VM agents for 500 VMs and 40 sockets (increasing to 70 TB)

The current DPE licence (100 TB) can be used for the 25 TB of application agents and therefore we need to work out which of the following will be the most cost-effective:

  • Add a further 20 TB of DPF
  • Add VM agents – either by:
    • Adding 40 sockets
    • Adding 50 x 10 VM packs

One interesting point of note is that, in some scenarios, it may actually workout more cost-effective to scrap some or even all of the current licences and start again.
