QSAN makes no guarantees for results generated with this tool. Synology RAID Calculator recommends models based on the total number and capacity of the selected drives. My current understanding makes me think that with - for example - a dRAIDZ2 you always have total data loss if more than two drives fail, because vdevs are using all drives. IBM distributed RAID (DRAID) technology provide up to 20% better I/O performance and up to 10 times faster array rebuild rate compared to traditional non-distributed RAID arrays. Power calculators. May 14, 2018 · IBM Distributed RAID (DRAID) improves RAID performance and availability compared to Traditional RAID (TRAID). Notes: 1 FBA DASD space allocated by CP for use as directory, paging, and spooling must reside within the first 16,777,215 pages (64 GB minus 1 page) of the volume. ha_reserve_percent: Percentage of capacity reserved for high availability. DDP improves the time and performance of traditional RAID arrays. a disk sector size of 4k and a data portion of 7 (see example 2 above) would result in a stripe width of 7 * 4k = 28k. Supported RAIDZ levels are mirror, stripe, RAIDZ1, RAIDZ2, RAIDZ3. Anything lesser than 30 drives (my opinion but iXsystems™ has best practices to be known soon) are not good candidates for dRAID. It offers the Group width in dRAID is defined as the number of data disks in the configuration plus the number of parity disks. Figure 1 shows an example of a distributed RAID array that is configured with RAID 6; all of the drives in the array are active.
