Balancer Multi Write /8 Copy from SSD

[Strezi]

Hi there,

 

probably more like a suggestion which would speed up balancing a great deal.

I'm using SSD caching with 256GB SSD mapped to 2x2TB + 2x3TB archive drives. When the balancer kicks in, there is only one file moved at a time. However, my archive drives could take 2 or 4 simultaneous copies not even saturating the SSD's read speed. Having the option to copy to all the drives at the same time would decimate the balancing time.

I was looking long and hard for windows file copiers having this option in vain.

 

Having this built in to DrivePool would make great sense, sinc it has first hand understanding of the drives and the balancing rules.

 

I hope its possible ;)

Basically, multithreaded balancing.   That is possible, and and a lot of our code is actually heavily multithreaded, actually.

The biggest issue is tracking what's happening, and make sure we don't attempt to move the same file twice... and to make sure that files are moved to the "correct" disks.  

Also, setting "FileBalance_BackgroundIO" to "true" may help here, as the balancing may happen faster (but may effect performance on the pool).
