Copying speed - SMB on 10Gb with large compressed files
Posted: Sun Jun 12, 2022 7:31 am
Hi
we're running a simple job to copy 25Tb of large compressed files (backups of VMs) from one Windows 2022 server to another one. Via SMB but have also tried sftp.
they are connected by 10Gb network cards and a 10Gb switch. we actually have 3x10Gb on each running in a bonded state, just to see if we can increase throughput.
the disks on both servers are RAID 5 with 12x 20Tb drives. servers are identical spec - 128Gb ram, 96 cores. lots of headroom. this is their only job.
we're seeing 25Tb copied in 12 hours. varies between 2Gbps and 7Gpbs when we run 4 file copies at once on the single job. seems faster than 1 and 8 file copies.
are there settings we can tweak to increase this? buffer settings? windows copy settings?
just need to blast these files over in the shortest window we can. (size varies from 1Gb to 800Gb)
cheers!
