Hi Vaulters,

 

Hope everyone is doing well.

We have a new commvault platform that will be installed, and we’ve been asked by our storage team what are the LUNs size that are needed for backed up data. In order for them to create and map them to our MediaAgents.

 

So, it’s a sizing question. Are there any recommendations per Commvault or utility that can be used to help us decide what’s the best storage configuration will fit our needs ?

 

Knowing that our platform will back up multiple workloads : VMs, FileSystems, DBs (SAP HANA), Mailboxes (Exchange), Active Directory ...etc.

 

Any recommendation from you guys would be much appreciated.

RegardS.

Hi @Sebastien Merluzzi,

 

Thanks a lot for your feedback.

Is there anything more precise ? In which we can specify the type of workload to be used (DB, VMs, Mailbox…etc.).

 

Kind regards.

We came across a Design Tool which seems to be a good start.

Following the below screenshot:

 

Can anyone give us examples on how to set up the “Retention” part, for example, having a weekly full and daily incremental with a retention of 15 days and 1 cycle. How can this be setup on the tool ?

 

Regards.

@Commvault Engineer Hi what is the sizing tool in the screen capture?

You can get to it via cloud.commvault.com

When I’m using the tool, I use it as a guide and don’t generally account for additional cycles in the primary copy, I’m not sure what the logic in the tool is but when you configure a plan these days it uses 1 cycle as the default retention setting so I assume it’s using that in its logic.  If you did want to take additional cycles into account, you would likely have to estimate the additional days. eg:
15 days, 2 cycles is a maximum of 21 days (with a 7-day full frequency), but if your cycle is shorter than 7 days your maximum retention is shorter as well.

I have an old spreadsheet that I got on a training course back in the Simpana 7 or 8 days that calculates the maximum days for a given retention in days/cycles which I still pull out every now and then.
