Anyone know how to view existing NIC MTU setting?

Thanks!

Dear Members,

If you have a primary and secondary open-e setup and each SAN is raid6

Did you check the trigger failover on I/O errors?

Hi Everyone,

Have you guys experience the following

Open-E ISCSI failover and OnApp Windows 2008 would fail to reboot because during booting up, the Windows 2008 complains that it is a new disk...

write cache is enabled for both raid controller and HDD

Please take note that the HDD is 3G/s spec.

If i am getting 300MB/sec ... i think that sounds about right ... but does it matter if I...

DRDB is set as following
max-buffers 8000
max-epoch-size 8000
unplug-watermark 128
sndbuf-size 2048
al-extents 127
no-disk-barrier off
no-disk-flushes off

the following was changed

MTU changed to 9000

Tested tasked speed 300M 400M and 600M

Speed is still the same

both units have 16 2TB drives on raid 6 using Adaptec 5805 MAXIQ

6 volumes each with 4000GB

replicating over a CX4 - 10G direct connect

Each of those 6 replication only runs at 41668 kB/s (72340 kB/s)

This is shocking. Any tips?

MTU for the interface...

This morning I woke up ... it seems like the speed has dropped dramatically!

changed the jumbo frames to 9220 and increase the SynSource bandwidth to the max 600MB

this is what I get :)

enealDC,

Thank you for the tips.

How about CentOS live CD and then use iometer?

It might not have the tool i need on CentOS for benchmarking.

So we test the I/O?

Here is the updated spec :)

The 10G port is going to be directly connected to the other SAN unit for replication purpose.

please comment :)

Thank you for the info guys.
