Promise SanLink2

[John Davidson]

Hey Steve,

Are there different settings when using the Sanlink2 on a TB1 iMac?

Thanks!

Actually, never mind – I’m getting this with regular old Thunderbolt1.

Not to shabby!

Whats the server your pulling from consist of ? Basestar ? NAS ?

We have a 16 Drive ProAvio array, controlled by an Areca 1882x and mounted to a 2010 Mac Pro. It’s being fed out via ethernet from a Netgear 10Gbe switch.
It is a NAS and BASESTAR is the name we gave the RAID because I loved the Battlestar Galactica reboot.

Hi John, Do you have the SANLink2 10GBase-T version? I can’t get the jumbo frames/full duplex/flow control up and running. My current speed is max 220mb/s.

[Chris Duffy]

In the System Preferences-> Network Preferences
click on the SanLink port,
click on Advanced
click on Hardware
change Configure to Manual
change Speed to Autoselect
now you can change the mtu to 9000 or whatever
apply and so on.

Thanks Chris, But my SANLink2 10G Base-T doesn’t allow me to turn on both Flow Control AND Jumbo frames (MTU 9000)…

[Chris Duffy]

When you select “autoselect” the speed greys out which means
it will auto-negotiate speed/duplex/flow-control for you
at the same time you select the MTU. So you will use
flow-control, 10Gbe and full-duplex doing this….

I think this issue with 9000 byte MTUs on 10GbaseT is fixed in 10.9.4.

Thanks Steve/Chris, I’m running 10.9.4 and put MTU to 9000 (auto speed select), but still max speed 200MB/s. Do you have good results with 10G Base-T version of SANLink2? Then maybe something else is causing this poor performance.

I also contacted Promise, but they are saying the SANLink2 is only for use with their storage. I have a Netsor storage with an Areca controller, Myricom NIC en a Netgear 10Gbe switch.
