Thunderbolt unreliable on 2013 MacPro

RE: Thunderbolt unreliable on 2013 MacPro
I have the same problem using a 5S and an Apple Firewire to Thunderbolt adapter. I was thinking of getting the 5D for the speed and the direct Thunderbolt connection, but if the 5D is having the same problem, guess I'll have to wait until its fixed, or get a Promise Thunderbolt 2 solution. Is it something inherent with the new MacPro Thunderbolt and Drobo of any model?

hi steve, what about usb3?

(btw i have XP home SP2, a Drobo v1 with 2x 1TB/2x 1.5TB WD greens, & a bkp Drobo v2 with the same + a DroboShare: unused)
& a DroboS v2 with 3xWD15EADS &2x1TB in DDR mode on win7, & a drobo5D (all usb)
  • btw i did a sustained (write) operation for about 6 hours, and got 13.2MB / sec ...objection? "sustained" :)
    (16.7MB/s on a v2 & 47-96MB/s drobo-s)

Hello Frank,
We do apologize for the trouble you experienced, the updated firmware for the 5D will resolve this issue - you can download from:

http://www.drobo.com/support/updates/

Thank You,
DroboMod

I used the 5D for 2 weeks before on an older MacPro with a USB 3.0 card and the issues have been similar.

The behaviour seems to be that, if the Mac was EITHER powered down, or sleeping for several hours, that the Drobo does not wake up anymore when the machine is restarted, or woken up.

Only way to get the Drobo to reconnect is to manually power it down and on again.

That seems to be a firmware issue, as, when examining the Thunderbolt bus on the MacPro, the Drobo 5D is still shown as connected. But neither the Dashboard, nor the terminal, nor the finder can find the drive.

Trying to create a ticket, but the Drobo site throws me an SSO error (and yes, i mailed them about that), so for now, i am trying to gather more information.

Is that a known/common/rare issue?

Regards

Frank

It works OK with USB (my 5S only has USB 2.0) but wakes up very slowly from MacPro sleep.

RE: Thunderbolt unreliable on 2013 MacPro
hmm, maybe the macpro is doing several things when it comes out of sleep, and then once its ready, it might only then be re-establishing/communicating with the drobo.

im not sure as i pretty much powerdown my drobo before logging off or hibernating or powering off the computer.

im assuming "sleep" is the same as hibernate? but if not, is your sleep, the equivalent of a screensaver (eg after 20 mins the mac goes to sleep?.. if so, is there a longer duration you can set it to, which might help your situation a bit more... such as if you usually take 30mins breaks from the computer, try setting it to 45mins before sleep?
also maybe there is a setting or something similar which is making the mac (recheck or reindexing something before re-establishing a ready connection with drobo again?)

have you tried it going to sleep and back, both WITH dashboard running, and WITHOUT?
