Hi, 

I have a customer that would like us to detail the hardware & architecture required to use Activate (Sensitive Data Governance) on the existing backup job data within their Commvault solution. 

The solution needs to be able to index and analyse 4PB of file system application data stored within the archive and backup deduplicated storage pool. The solution would also need to scale to support a live crawl of the file system data on the servers in the future. 

The current architecture has a limit of 160TB per node. Using this architecture guideline would result in a large index server hardware footprint (25 servers for indexing alone). 

Is there potentially a different architecture guideline to follow for big data sizes?

Hi Hemant, 

I will discuss this internal and find out for you. 


Thanks Blaine


Hi Hemant, 

Can we get answers (approx) for below:

1 – Do they need to do sensitive data analysis on complete 4PB?
2 – What kind of files do they have?
3 – What is approx. average file size?
 


Hi Blaine,

 

There is archive and backup data in a Commvault deduplicated storage pool. 

It is made up of File System data.

The application size of all the jobs totals over 4PB.

The files are office based extensions, with an average of over 1MB per file. 

Please let me know if you need anything, appreciate the assistance. 


Hi Hemant, 

You didn't answering the following so I have elaborated further, can you please advise. 

1 – Do you need to do sensitive data analysis on the complete 4PB of data?
2 – What kind of files do they have in there. Eg, all doc, email etc...?


 


Hi Blaine, 

 

1 – Do you need to do sensitive data analysis on the complete 4PB of data? Yes

 

2 – What kind of files do they have in there. Eg, all doc, email etc...? Office based extensions e.g. .doc, .pdf, docx, etc. 

 


@Hemant 

Roughly there are 400 million objects as per average size 1MB.

We will require at most 5 large access nodes (Index serve, CA and gateway/webserver). We have lots of optimization which helps in picking correct document for SDG so we can except this count to be less.

Also we recommend large environment configuration to be done incrementally so that we can scale accordingly.

I hope this helps your planning. 


Thanks @Blaine Williams , much appreciated. 

Is the optimisations available on BoL to review? 


@Hemant , I believe @Blaine Williams is referring to internal code that is optimized at its tasks.

I’ll defer to him if I misunderstood.


Thanks Mike.
