EMCopy GUI?
posted by Julian Firminger on March 12, 2015, 8:15 a.m.
Hi all,

Anyone out there built or found a GUI for EMCopy?
I have a need to leave it with non-technical users. (read VERY non-technical)
Robocopy is not cutting it performance wise before you ask.

I've got a PDP-5020FD Kuro plasma which seems to have been set to disable any access to setup menus (I'm not talking about secret service mode menus, just the basic stuff). Anyone know of a magic incantation to re-enable this from the remote? Google hasn't found anything useful for me so far.

Smartfaling isilon nodes - experiences?
posted by Rory Falloon on March 13, 2015, 1:45 p.m.
Hi,

I have 5 nodes of a 13 node x200 cluster to send elsewhere - while I await EMC to send me some best practices based on cluster configuration, does anyone have stories or otherwise on the process? Run into any issues that EMC didn't outline, or problems you didn't foresee when starting the process?

Thanks

Windows Server 2012 reverted to years old state
posted by Michael Oliver on March 13, 2015, 4:15 p.m.
Really random issue..wondering if anyone else has encountered it and/or knows a quick fix besides a complete restore from backup.

Applied some windows server 2012 updates yesterday and restarted the backup DC. When it came back up it did a time warp to 2013. Profile folders are gone, installed programs (ie Quickbooks) are gone with the exception of a couple programs that were installed back in 2013, it is basically a freshly installed copy of Server 2012 with a really old copy of AD users/workstations/groups. So syncing is definitely an issue but that is a fairly easy fix. The bigger concern is all the program files / profile folders that were wiped.

Restore from a backup is always a solution but what I am more interested in is what would cause such a thing? Seems like incredibly terrible behavior.

Six-Month(ish) Check-In: Trashcans
posted by Rob LaRose on March 16, 2015, 1:50 p.m.

So About 6 months in, has anyone found a racking/mounting solution they actually like for the mac trashcans?  Particularly in client-facing areas like edit bays?

For my money, it seems to have only caused more trouble:

- Racking two side by side needs 6U to make ports accessible
- Sitting on the desk its beautiful if nothing is plugged into it
- Thunderbolt cables come unseated easily
- Power button is under the cable mess.. pressing it pretty much guarantees youre going to unseat something.

Hello,

Did any of you experience a power outage in the Soho Area?

We experienced one around 16:30.

Power was back immediately after it went out. So it was less than a minute.

Wondering if other studios experienced this as well.

Rgds!

USB3 or Thunderbolt Stand Alone LTO6 Drives
posted by Bobby Jain on March 18, 2015, 4:30 p.m. (1 day ago)
I am trying to track down a USB3 or Thunderbolt LTO6 drive to have at the studio to backup footage after it comes out of the camera. We will be looking to use the drives with LTFS so we can transport data between facilities, to free up the SSDs which come out of the cameras.

IBM seems to have a USB3 version, which I cannot find for sale. mLogic has a TB version, which you can buy right off their website. I would prefer the USB3 version so that it can be universally used (drivers permitting). The only info I can find on it is below:


mLogic Thunderbolt drive:http://www.mlogic.com/products/mtape

Anyone out there with experience with these stand alone drives? I asked Quantum, but they only sell SAS or FC.

http://qumulo.com/

Apparently started by ex Isilon folks, scale-out NAS architecture, software only or appliance-packaged, NFS+SMB+REST, analytics built-in as opposed to an additional cost package.

Oh, just saw the quote from Saker:

so I guess at least one person on this list has taken a look at it :-)

External GPU via Thunderbolt
posted by Brian Krusic on March 23, 2015, 2 p.m.
Hi all,

Ive a Sonnet Express 3 and am getting no GPUs to work.

Ive tried ATI Radeon 5770, NVidea GeForce GTX780 and GT740SC.

Nothing shows up under PCI or Thunderbolt sections of the sys info section under 10.9 or 10.10.

In fact, what does show up is something to the effect of error reading info.

Ive an external power supply so juice is no issue.

Ive read were Intel doesnt want to approve external GPU via TB as theyd rather one buy a strong laptop for this purpose.  Since they own the spec they can do whatever they like.

Of course Im neither here nor there on this as I simply wish for my endeavors to be fruitful.  

At any rate, wondering if any one has accomplished this with any sort of TB case; eternal Nvidea GPU via Thunderbolt on a trash can running 10.9.5?

There are some articles on modifying a driver etc.. for use with this but before trying any shenanigans which I am more then capable of doing, I thought to reach out to my more experienced colleagues.

Hope you have some nuggets for me.

Thanks in advance,

- Brian

Hi everyone,
we are currently testing 10GigE cut-through switches (Arista, Force10/Dell, IBM, Brocade). What are you guys using to
test overall bandwidth, congestion, switch buffers and latency? Iperf and running tons of file transfers (what we do right now) does not feel like
a best practice approach. There is a company called ixia which builds various testing devices (http://www.ixiacom.com/routing-switching) but I can't
find anything open source or free on a Linux basis to do this.

Hi,

I suggest doing netperf as well.

I recently used these to debug my 40Gb network, special thanks to Richard Hastie@Mellanox BTW,

Iperf
 
for max BW i typically use :

Server:

iperf -s -l64k

Client

iperf - c<ip of server> -l64k -P2

 
Netperf
 
 
Server: netserver 

Client: netperf H <server IP addr> t TCP_RR 

The result is transactions per second (TPR). 

Latency is calculated as: Latency=(1/TPR)/2
 
 
netperf -H 11.10.10.12 -t TCP_STREAM -I 99,5 -T 2,2
 
 
 
Another few examples
 
netperf H <server-ip> -t TCP_STREAM I 99,5 T 2,2 
netperf H <server-ip> -t TCP_STREAM I 99,5 T 2,2 -- -m 2048 
netperf H <server-ip> -t TCP_STREAM I 99,5 T 2,2 -- -m 1024 
netperf H <server-ip> -t TCP_STREAM I 99,5 T 2,2 -- -m 500 
netperf H <server-ip> -t TCP_RR I 99,5 T 2,2 -- -m 1024 

netperf H <server-ip> -t UDP_STREAM I 99,5 T 2,2 
netperf H <server-ip> -t UDP_STREAM I 99,5 T 2,2 -- -m 1024 
netperf H <server-ip> -t UDP_RR I 99,5 T 2,2 -- -m 150

Of course tweak your server/client cards as well and not just TCP fromage but IRQ affinity etc

Client: netperf H <server IP addr> t TCP_RR 

The result is transactions per second (TPR). 

Latency is calculated as: Latency=(1/TPR)/2
 
 
netperf -H 11.10.10.12 -t TCP_STREAM -I 99,5 -T 2,2
 
 
 
Another few examples
 
netperf H <server-ip> -t TCP_STREAM I 99,5 T 2,2 
netperf H <server-ip> -t TCP_STREAM I 99,5 T 2,2 -- -m 2048 
netperf H <server-ip> -t TCP_STREAM I 99,5 T 2,2 -- -m 1024 
netperf H <server-ip> -t TCP_STREAM I 99,5 T 2,2 -- -m 500 
netperf H <server-ip> -t TCP_RR I 99,5 T 2,2 -- -m 1024 

netperf H <server-ip> -t UDP_STREAM I 99,5 T 2,2 
netperf H <server-ip> -t UDP_STREAM I 99,5 T 2,2 -- -m 1024 
netperf H <server-ip> -t UDP_RR I 99,5 T 2,2 -- -m 150

Of course tweak your server/client cards as well and not just TCP fromage but IRQ affinity etc

Hi everyone,
we are currently testing 10GigE cut-through switches (Arista, Force10/Dell, IBM, Brocade). What are you guys using to
test overall bandwidth, congestion, switch buffers and latency? Iperf and running tons of file transfers (what we do right now) does not feel like
a best practice approach. There is a company called ixia which builds various testing devices (http://www.ixiacom.com/routing-switching) but I can't
find anything open source or free on a Linux basis to do this.

Cheers
