<blockquote type="cite" class="">Hi all,<br class="">
We have a a few servers conected via 10g nic LACP, some of them have 4nic and some have 6nic in a link aggregation mode. We been moving a lot of data around and we are trying to get the maximum performance. I have seen zpool can deliver 2-3GB accumulated
throughput. Iperf does about 600-800MB/sec between those two servers.<br class="">
Given the hardware that we have and the zpool performance, we expected to see some serious data transfer rates however we only see around 200-300MB/sec average using rsync or copy paste over NFS. Standard MTU 1500 and nfs block size. I want to ask
the community what to do get some higher throughout and the application level. I hear ZFS send/receive or ZFS shadow does work faster but it does snapshots. Out data (Terabytes) is constantly evolving and we prefer something in the nature of rsync but
to utilize the network hardware.<br class="">
<br class="">
If Anyone has a hardware setup that can see 1GB/sec throughput and does not mind sharing?<br class="">
Any software that use multithreads sessions to move data around zfs friendly? We do not mind getting going with a commercial solution like camvault or veeam if they work.<br class="">
<br class="">
Thank you for your time<br class="">
