... unless you do reversed incremental like Veeam does and it triggers tons of random. ... Should I expect it to allow me to set the block and stripe sizes?
31.12.2017 · Then there is the "stripe" size which is equal to the strip size x the number of drives in the stripe. In your case, a 4 disk RAID 10, it would be strip size x 2 because of the mirroring. A RAID 0 would be strip size x 4, RAID 5 would be strip size x 3...
21.11.2020 · Block Sizes As can be seen from the field, optimal value for the stripe size is often between 128 KB and 256 KB. However, it is highly recommended to test this prior to deployment whenever possible.During the backup process data blocks are processed in chunks and stored inside backup files in the ba...
17.02.2015 · This means the same backup job will last 6,86 hours. Compare it with the previous result of 20,6 hours, and you can immediately understand the importance of configuring the right stripe size on your Veeam repository. Also, the RAID level is important. We often suggest customers, if budget allows, to use non-parity based RAID like Raid10.
31.08.2016 · RAID 6. This has the most severe performance overhead (6x write penalty) There are also a few points on stripe sizing if you can configure this on your RAID volume. Typical I/O for Veeam is 256KB to 512KB, Windows Server 2012 defaults to 64KB, some arrays to 32KB. That’s a lot of wasted I/Os!
09.06.2021 · My question is regarding the stripe size during the RAID build. Dell Perc H740P does allow me to define the stripe size. I have read in Veeam KBs to use 128k or 256k stripe size for backup repositories. My question is which should I pick (128k or 256K)? Dell doesn't allow me to pick the block size during the RAID build, so it will be 512 bytes.
26.05.2016 · Re: Reverse incremental performance on Raid 5 vs Raid 10. That means that the source disk reader component is the "weakest" point in the data processing conveyor and the following stages are waiting for it to provide data, while the source disk reader spends all of the time reading the data.
