Hi, Thanks for you response.

We are 80% mac. Our 3D team run PC.

I am 100% sure the 2 server ports were aggregated with the 2 x ethernet cables coming off the sanlink TB to ethernet device, into the switch. The switch seems to be 1Gb only (SGE2010P 48-Port Gigabit Switch)

All workstations are gigabit

Have not customised the sysctl as in the settings in this thread – not 100% sure what this isor where to tweak the settings, but we have a new tech support solution lined up so I will show them the settings you refer too.

Each Sanlink device was plugged into their own thunderbolt port, however I was told they are on the same bus.

As per your suggestion, we removed the aggregation with the Sanlink TB – Ethernet box, and connected with just 2 x built in ethernet ports to the switch. This setup appears more stable, for 1 day so far anyway. I will continue to test this for another few days. Far less reports of network slow down, no corruptions as yet. I will report back if this helps.

Yes – we did have 2 x sanlink devices. The reason I asked about having 2 x sanlink on same machine would cause problems was this – when we disconnected the sanlink2 10 Gb Base-T, i tried plugging the device back into the server later that day. The device was not recognised by OS X or the sanlink utility this time. I wondered if there is a conflict using both a Sanlink2 Fibre Channel (for the raids) on the same machine as a Sanlink2 10 Gb Base-T. Or Maybe this is a sign the Sanlink2 10 Gb Base-T is faulty?

We plan to keep all workstations / clients at 1Gg for now. No 10Gig clients.

Thank you so much for your help and support.

Hi All.

We are having difficulty in our studio with a new server install. The company who installed it have been unable to troubleshoot it so we have abandoned their support and are looking elsewhere for a new tech team. I am not a system administrator, just but I work here as creative professional and doing all I can to help fix the problem in short term

Since the install, we have major network stalling during file transfers, file corruptions, slow directory browsing, slow network transfers, clients crash when reading or browsing server. All symptoms are intermittent.

The setup is

2 x Promise raids connected to Mac Pro (late 2013) running server via Sanlink2 Fibre channel to Thunderbolt (f2101) device. The Mac is connected to Cisco switch via what I think is an odd aggregation, consisting of 1 x Sanlink2 10g Base T to thunderbolt device, aggregated with the 2 x Ethernet ports built in to the mac pro server.

All clients are 1gb Ethernet connected to the switch.

I have two key questions – 1. What is your opinion of the way that the server / switch connection was aggregated? (Ethernet and sanlink2 together)

2. Is there compatibility issues running two thunderbolt sanlink2 devices on the same MacPro?
