Good day, I would like to talk to you about Rain Zicks, and so Rain Zicks, the minimum
is 4Disk, and just like Rain V, this does block level striping, so that means it
stripes across all disk in the array or in the lawn, and picture a diagram with 4 set
onters in it, and each disk is labeled this one, just 2, just 3, just 4.
And so each block has an alpha numeric thing, and so you have 5 blocks, so it's A, B,
C, D, E, E, F, and these blocks are spread out over these 4 disks.
And then the parity disk is, then there's 2 parodies, there's 2 parodies for each one,
so it's a dual parity solution, so it's like the parity blocks are P1 and P1,
P2 and P3, and these are spread out over the disk, and so then you would have the
second parity would of course be 4, P4, P5 and P6, and this, when you do this again,
it's two parodies blocks for each beta block written, and the reason this is so great
is that it can handle two disk failures, and this rate configuration is complex to implement
in a rate controller, so because it has to calculate two parity data for each block,
and so for instance, when a drive does fail, and you pull it out, well then you put it
in a new one, and then the controller has to process the parity, and this takes quite
a while, and so this is why in inter-proserase, you always look at how many cores each controller
has in order to make that work, okay, so this is about it for a rate 6 block striped
to distributed parity solution, all right, you'll have a fantastic time, and take
her, bye.
