Hello everyone,
I can't figure out the issue why my snapmirror over 10Gbps network not exceeding 370Mbps.
I've created a snapmirror between two clusters FAS2750 and FAS2552
Both have SAS disks, they're conncted to the same Juniper 10GbE switch.
FAS2750 have LACP configured for two ports, FAS2552 have one dedicated port for replication.
1. disabled Flow-Control on Juniper and Netapp
Juniper = set interfaces xe-0/1/6 ether-options no-flow-control
ONTAP = network port modify -node <node> -port e0d -flowcontrol-admin none
2. increased TCP windows size (both clusters)
options snapmirror.window_size (8,388,608 bytes for 10GbE network)
3. Throttle disabled (both clusters)
replication.throttle.enable off -
replication.throttle.incoming.max_kbs unlimited -
replication.throttle.outgoing.max_kbs unlimited -
Juniper interface transfer rate 387315168 bps rate
monitor interface xe-0/1/6
ONTAP interface transfer rate 38.9 MB
statistics show -object nic_common -instance e0d -counter rx_bytes -node <node>
node run -node <node> sysstat -c 10 -x shows
Source 30% CPU and 80% Disk Utilization
Target 90% CPU and 90% Disk Utilization
i'm lost and made too many changes to find the root cause, any advices ?
