Running Lancache on a Disk That's Not Assigned to Parity

[rjdipcord]

Hello all,

 

I am trying to setup a fast Lancache on my network. I would like to use a 500GB Nvme drive as the primary disk the lancache will use. I am using this type of disk because I want to remove bottlenecks as much as possible, since my network bandwidth to each client will be 10Gbe. I know the Nvme can keep up to the demand within reason. I am getting reads up to 3 Gbps off the disk using lancache. However for the initial download of a Steam game, I am only getting about 500 Mbps. I have deduced this is because the SSD is in my primary array, and the parity writes are slowing down the read performance to the maximum bandwidth of the parity drive.

 

I want to assign mount this disk without parity. Since it's a cache, there will be no files stored which are important. I realize I can assign this drive to a cache pool, and point the Lancache share to the cache, but I don't know that this is the best way to do it since Mover will eventually move the files to the main array at some point - which uses slower disks.

 

What are my options?

 

Thanks!

Only if you configure the share to have this behaviour.    You can configure a User share to never be put on the main array.

Wow I don't know how I missed that. All I would need to do is set the share up on the cache to "Only" instead of "Yes"

 

Thank you for the help!
