DRAID6 is advised for FS9100, 9200, 7200 and 5100 systems, and is the only allowed option from the GUI. DRAID5 is configurable using the CLI. DRAID6 creates spare space across all NVMe SSDs or FCMs on the array and, during failure, the array rebuilds data using the spare space faster than traditional RAID rebuilds. That is the issue, I don't have a system to test D-RAID6. I am basically building the spec of the new server and IBM threw this DRAID6 into my head as the next best thing for SSD array, if it wasn't for the "distributed" part of it I wouldn't even be posting here and would go with RAID10 but the benefits of the distributed RAID got me thinking. IBM Flashsystem, 5015, 5035, 5200 and 7200 upgrades, parts, maintenance and implementation services. View our IBM FlashSystem 5200 price table. Up to 24 of these modules can be accommodated in a 2U controller housing. Each of these modules provides a capacity of 4.8 or 9.6 TB, up to a maximum of 19.2 TB (uncompressed).

I greatly appreciate the support and direction. From what I can gather in everyone’s answers doing a RAID 6 for my needs will be sufficient, as long as I’m using enterprise level drives (i.e. Western Digital RE, SE level drives) and cn108845771a cn201810660972.1a cn201810660972a cn108845771a cn 108845771 a cn108845771 a cn 108845771a cn 201810660972 a cn201810660972 a cn 201810660972a cn 108845771 a cn108845771 a cn 108845771a DRAID6 .
With today’s larger storage drives, minimizing rebuild time is critical, to avoid a double-drive failure and possible data loss. These arrays, which can contain 4 - 128 drives, also contain rebuild areas that are used to maintain redundancy after a drive fails.

So why is this important? With today’s larger storage drives, minimizing rebuild time is critical, to avoid a double-drive failure and possible data loss. These arrays, which can contain 4 - 128 drives, also contain rebuild areas that are used to maintain redundancy after a drive fails. As a result, the distributed configuration dramatically reduces rebuild times and decreases the exposure volumes have to the extra load of recovering redundancy. Using mismatched drives in RAIDZ2 or DRAID6 Hey guys, I'm new-ish to this arena of non-traditional RAID and trying to understand how capacities vary. I've spent quite a while on the Googles and Youtubes trying to figure this out and am stumped. When I introduced the updates in Spectrum Virtualize 8.3.1 I promised a dedicated post discussing the details around the new DRAID dynamic expansion feature.

Things used to be quite simple and I covered this for many years in my Configuring for Optimal Performance series of technical university presentations (also here on the blog – parts 1, 2, 3) – and the basics are still the same when configuring RAID arrays
IBM Distributed RAID (DRAID) improves RAID performance and availability compared to Traditional RAID (TRAID).

If I would want to use some sort of parity RAID I would opt for double redundancy and a more intelligent approach (that's RAIDz2 or btrfs raid56 created with '-draid6 -mraid1').
