What is RBS, what is difference between RBS and Shredded storage in sharePoint 2013
Shredded Storage and RBS complement each other. Shredded Storage reduces network and storage I/O when saving document edits. And RBS reduces Content Database size, improves upload and download speed, and accelerates backup/restore operations. Following the guidelines above will help you get the most out of RBS and Shredded Storage.
There is a lot of misinformation currently floating around about Shredded Storage and RBS in SharePoint 2013. The reality is that neither replaces the other.
In SharePoint Server 2013, Shredded Storage and RBS coexist without issue. Shredded Storage is a single file broken down into smaller “chunks” and stored within the SharePoint Content Database. With RBS in place, the smaller “chunks” will be externalized rather than a single file. Regardless of shredding, the end result is the same: BLOBs are stored outside of SharePoint Content Databases.
While Shredded Storage cannot be “turned off” in SharePoint Server 2013, it can be optimized or disabled altogether by changing the chunk size of the file shreds. The default chunk size is set to 64KB, but you could set the chunk size to 2GB (the maximum allowable file size in SharePoint), which effectively disables Shredded Storage. When performance testing Metalogix StoragePoint with Shredded Storage, we found that setting the chunk size to 20MB will yield the best upload and download performance. Changing the chunk size is quite simple and requires a bit of PowerShell script.
$service = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$service.FileWriteChunkSize = chunk size in bytes
wW need perform an IISRESET and restart the SP Timer Service on all machines in the farm. Happy Coding 🙂
