The minimum drive dount in one array (DRAID6) is 6 (3+2P and 1HS), but ideally you'd have around 48-60 to really benefit from it. Otherwise (with the minimum) there isn't much difference to TRAID. Answer by ScaleoutSean 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'). No more contributions to this project until 'alternative facts' (AKA ignorance/stupidity) are gone 2015-03-29 · First, Thank you everyone for the prompt responses. I greatly appreciate the support and direction.

A datastore, preferably a remote NFS or iSCSI one, where backups can be stored. Installation. Download the ghettoVCB VIB and then using your tool of choice (e.g. the vSphere Client or FileZilla over SFTP), transfer the VIB to your ESXi host. The minimum drive dount in one array (DRAID6) is 6 (3+2P and 1HS), but ideally you'd have around 48-60 to really benefit from it. Otherwise (with the minimum) there isn't much difference to TRAID.

Finally, what about a DRAID6 array? I've read plenty about "DRAID expansion" for adding drives to a pool, but nothing about what happens when you replace a failed drive with a larger one. As I said, I searched for a while on this and came up empty.

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. Before we dive in, there are some DRAID basic terms that you need to understand.

Draid6

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.

It makes a lot of sense to go for a 3 disk raid 6.
