Push Gigabit NIC teaming to the limit for NAS backup in SOHO
I have both Pro4 and Pro6 NAS unit which both support NIC teaming. However I'm not happy about the NAS to NAS backup speed, For full backup, around 30-40MB/s is what I can get, teaming or not. How to...
Not sure whether anybody get similar result with my configurations. For myself, I copied over 10TB data between two NAS(a few hard drive RAID set) in last week. Generally I'm able to achieve at least 130MB/s, the highest result is 180MB/s from 4-disk RAID0 set to 6 disk RAID5 set for 2.5TB data. Considering the cost of SG200-08(less than $100 from local reseller), I'm very happy about the result.
Something I need to mention
1. bbcp is not for novice NAS user, need basic linux knowledge. After bbcp copying, some file ownership/permission fix is required.
2. bbcp could bs installed on both OS4 and OS6, however, if the destination NAS box runs OS6, bbcp performance is very poor(30-40MB/s at most). If same box run OS4, everything OK. I had tried PC run Debian 7 x86_64 as destination, everything OK as well. OS6 box as source is OK as well. Not sure what changes ReadyNAS developers commited to kernel or network settings.
3. bbcp could be slow for huge amounts of small files, the workaround is to use tar as pipe on both side. An interesting article to read: http://moo.nac.uci.edu/~hjm/HOWTO_move_data.html also covered other file copy tools available.
StephenB, regarding your question, if I disconnect one cable on destination during the benchmark testing, the throughput numbers will drop slowly, but after I connected it back , the throughput numbers will get back slowly. Tested under dynamic LAG mode. If the benchmark test is start with one cable on destination only, the throughput is around 90MB/s, less than expectation of single ethernet connection.
