Equipment:
TS-253D, 2x Seagate Ironwolf Pro 8TB drives (7200rpm) in RAID 0
Mac Mini (2018 model, i7, 10gb NIC)
Ubiquiti network gear (Dream Machine Pro, Unifi Aggregation Switch, Unifi gen1 24-port switch)
Setup: I have both my Mac Mini and the TS-253D connected to the aggregation switch via rj45 SFP+ adapters. The NAS connects at 2.5gbps, and my Mac connects at 10gbps. Other devices are connected to the various switches. I'm starting with a factory reset NAS. All I've done is setup the drives, turn off a few unneeded services, and setup some shares.
From my Mac, using Blackmagicdesign disk speed test, I get about 270MB/s read across a network share using SMB 3. I figure the read is basically maxing out the drives. Write is anywhere between 10MB/s and 80MB/s, but usually on the low end. Using AFP, I get about 60-70MB/s write, and 270MB/s read. A windows machine on gigabit gets about 110MB/s read and write, pretty well saturating its connection. If I put the NAS and the Mac both on the gigabit switch, it also gets about 110MB/s read and write.
Complicating the troubleshooting, the aggregation switch (8x SFP+ ports) is new as well, and the Mac and NAS are my only faster-than-gigabit devices.
So I feel like I've narrowed it down to
- Something about the interaction between my Mac and the NAS doesn't like to happen at line speeds greater than 1gbps
- Something's wrong with the switch
- Something's wrong with the SFP+ modules I used (Wiitek from the ServeTheHome guide
- Something else I'm missing completely
Apologies for the long post, but like I said, I'm hoping someone sees something obvious here. It's been a long day of troubleshooting. Thanks!
