Just upgraded my home lab to 10GbE, picked up a cheap 10GbE NIC... and I'm looking to reduce the hard drive speeds as a bottleneck.
Currently I don't have raid, and my SAMBA shares act as a landing zone for Greyhole to run in the background and distribute files on other drives for redundancy.
Since this home NAS is a bit of DIY fun, I'm looking at cheap and creative ways to take advantage of 10GbE,
- Could I add a RAID / SSD array as a cache to frequently accessed files?
- Or is my best bet to put the SAMBA shares on a more classic RAID, which doubles as the Greyhole landing zone. I'm not sure how this will affect read speeds, but I guess if I make the RAID LZ big enough, and also a destination drive, most reads will come off that drive?
- Or is it time for a rebuild? I love Greyhole and its ability to pool storage across random sized drives. But if it's not going to be performant I may look to change things.
- Finally, are there any resources on how I can optimise Linux with my build in mind for multi GB LANs?
