Hi Experts,

I am using Symantec Backup  Exec 2010R3 and I want to use Deduplication.
But when I setup my storage MD1200 I will be asked what kind of block size or STRIPE ELEMENT SIZE I want to use.

I can choose from 64KB up to 1MB.
What is the best setup when I want to use this array for backup to disk with dedup ?

A stripe is the smallest chunk of data within a storage array that can be addressed. This is  also called as granularity or block size. Typical options are 16, 32, 64 and 128 kB, but many professional RAID controllers also offer smaller stripe sizes, and some even support sizes as large as 256 KB

Since this is used for data back up, you need to optimize this for capacity.

The stripe size also defines the amount of storage capacity that will at least be occupied on a RAID partition when you write a file. For example, if you selected a 64 kB stripe size and you store a 2 kB text file, this file will occupy 64 kB. Obviously, the stripe size defines the minimum amount of data that a storage will distribute files across its hard drives, in this example, 64 kB.


Hope this clarifies!
