DDB Blocksize

Hey All,

I have a question to the following scenario:

Actually the flashcard is formatted with 4K blocksize and we are planning to format the disk for 32KB blocksize as written in BOL ( https://documentation.commvault.com/11.24/expert/12411_deduplication_building_block_guide.html )

On the Flashcard we are hosting 3 DDBs.

DDB is for backups to an cloudian Backup Device over S3 Protocoll in local Datacenter
DDB is for Backups to SAN Attached STorage
DDB is for backups into S3 Storage out of the Datacenter

I have the following question. Can we use one Windows Partition with 32K Blocksize or should we make 3 partitions with different windows block size ?

The second question is which blocksize we need for the DDBs ? ( Block level Deduplication factor ) for all 3 DBs

If you have a question or comment, please create a topic

@SSchmidt , you likely don’t want to put 3 DDBs on the same disk as a start as that’s generally recommended against.

I’ll defer to some other member’s thoughts on the block sizes, though this Article here is somewhat related”
