Hi Everyone,

I?d like to remind everyone in the Vancouver area or those visiting, to join us on February 20th (Wednesday) for our first Vancouver StudioSysadmins meeting of 2013. We need to get a handle on how much food a beer to order so please RSVP if you are interested in attending. I'll be sending out a final reminder Wednesday morning.

This month?s topics are ?The Ultimate Remote Workstation Experience?, ? Fluid File System on Compellent Storage?, and ?Application Aware Power Management in Digital Media?


Remote Workstation:Whether it?s movie post-production, animation, CAD design, medical diagnostics, geospatial analysis, or stock trading?all require a powerful computing capability and are usually graphically intensive. Both these requirements are particularly challenging for VDI. However, Teradici?s PCoIP workstation solution benefits from the intrinsic attributes of PCoIP technology and has become the solution of choice for power users looking for maximum remote performance.

Fluid File System: Dell Fluid File System is designed to go beyond the limitations of traditional file systems with a flexible architecture that enables organizations to scale out non-disruptively. The Fluid File System architecture is open-standards based, supports industry-standard protocols and provides innovative features relating to high-availability, performance, efficient data management, data integrity and data protection. As a core component of the Dell Fluid Data architecture, Fluid File System brings differentiated value to the various Dell storage offerings. It is a network attached storage (NAS) file system accessed using CIFS and NFS protocols, but it has features and enhancements that make it unique

Power Management: This session will share how TSO can show you where power is being used to
create revenue and where it is being used to powering inactive servers.

Biographies:

Kenny Pak - Inside Sales Rep, Teradici
Kenny Pak is an Inside Sales Representative for Teradici; the creators of the PCoIP protocol where he delivers on client needs through support and education on the value of PCoIP technology in both workstation and VDI solutions.

Changing MTU size on bluearc to support jumbo frames

0
0
By Kar Hung Tom - Hey guys,

We currently experimented with rendering 4k stereo frames and our bossock fibers maxed out at 400. So we currently transmit packets at standard ethernet MTU size of 1500. We were thinking of enabling jumbo packets (essentially MTU sizde of 9000) on the bluearc but we were not certian what effect it would have on a live filesystem to all connected clients. I've reached out to Hitachi about this but dealing with them is a slow process and hoping I can get an answer sooner. If anyone has experience with this, it would be much appreciated. We want to run tests with render nodes transmitting packets with jumbo frames to our bluearc to see if it helps with 4k frame renders. By the way, we were able to identify the bossock fiber hoggers by using the tcp-per-connection-statistics-start command and pirs that was suggested by Greg Whynott on the BOSSOCK FIBER thread. So thanks to Greg for that.

Thanks

Alexa Log C - Grading tools & LUT presets

0
0
By Fabrice Altman -

Hi,

 

I’m looking into having a fast and cheap turn around for grading Alexa Log C footage.

 

So far, I’ve tried :

After Effects with a .cube LUT from Arri’s  LUT Generator tool.

BlackMagic Resolve LE with its factory LUT preset for the Alexa.

Nuke 7 with its factory LUT preset for the Alexa.

 

The one that gives us the best preset starting point, by far, is NUKE.

 

But we’d rather spend Nuke time for composting rather than grading.

Anybody had success with cheap AFX, Resolve LE or other ?

 

Cheers,

F.

Changing MTU size on bluearc to support jumbo frames

0

By Nick Allevato - well, MTU is merely a maximum.

your switch should have the MTU to 9000. This will increase the allowable packet size in general.

Clients and servers that you are looking to tune perofmrance of should have thee MTU set to an appropriate size. OSX is something like 8982 (to allow for header size, google this) and Windows I think can be set to just 9k.

How do you know that jumbo frames will help? Are you seeing a raw throughput issue from your nodes? Stereo 4k...that sounds like about 150MB of data per frame? 2k EXR is like 50 MB or so right ?

So confirm those numbers....where exactly is your pain point? Are the ndoes lagging on frame writes?

Subject: Re: [SSA-Discuss] Changing MTU size on bluearc to support jumbo        frames

I just asked an artist to confirm and they say on average, it's about 100MB of data for stereo 4k and 50MB for 2k EXR. Our pain point is once we allow a 4k render job to run and process a certain amount of frames (5 nodes each processing 2 frames), the whole network gets to a crawl as the bossock fiber rockets to the maximum value of 400 which means it has reached the maximum of network threads on the bluearc. So until the process finishes or gets killed, the network is slow to respond to requests.

Just to share my world-weariness with the rest of you...

From a vendor's support site.  First, the items required to log in and create or check a service case:



And second, the "attach a file to this case" tool:




?guess what you click to upload the file?  Never mind the fact I had to install Silverlight to even use the file-attachment feature.

Le sigh?.

By Michael Oliver -
The Open Source OS for the Internet of Things. ?For you?hobbyists?out there this looks interesting:?http://www.contiki-os.org?

"Contiki is an open source operating system for networked, memory-constrained systems with a particular focus on low-power wireless Internet of Things devices. Examples of where Contiki is used include street lighting systems, sound monitoring for smart cities, radiation monitoring systems, and alarm systems"

"Contiki only needs a few kilobytes of code and a few hundred bytes of RAM.[3] A full system, complete with a graphical user interface, needs about 30 kilobytes of RAM."

Linux SSH Rootkit

0
0
By Shane McEwan - G'day! There's been talk recently on various forums about a Linux Rootkit going around.[1][2] Details are sketchy and contradictory at the moment but from what I've been able to glean from the forums: 1. /lib*/libkeyutils.so.1.9 is the rooted file. If this exists on your machine you've probably been compromised. 2. Noone knows yet how the file is being installed on systems. There could be multiple exploits being used to gain access to machines. 3. Some infected machines have been seen sending out large amounts of spam E-Mail while other machines do not. 4. The rooted libkeyutils.so is used by sshd and some people have reported that the rooted file is collecting ssh login credentials and sending them in UDP packets to port 53 on 72.156.139.154. These packets look like DNS packets but actually contain the username and password of the person logging into ssh. 5. Most (all?) of the infected machines seem to be Internet accessible so you should be checking your machines that have an Internet presence before worrying about your internal machines. If your machine is compromised you can fix it by: 1. Removing the /lib*/libkeyutils.so.1.9 file and fixing the /lib/*/libkeyutils.so.1 symlink to point to the correct file (which is dependent on your distro). 2. Reboot. Note, however, that there's no guarantee that other files on your machine haven't been changed as well. A complete rebuild of your machine is recommended. Also, because the attack vector isn't known you'll likely be re-infected. There's various shell scripts submitted on the forum mentioned above purporting to fix the problem but I wouldn't recommend running them without understanding what they do. Most scripts are written for a specific distro and could break your machine if you're running something else. Thankfully my 6 Internet facing machines were all clean and none of my internal machines have access to Internet DNS servers through the firewall so credentials wouldn't leak out anyway but it's still a scary thought.
