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. A graduate of Simon Fraser University with a degree in Electronics Engineering his career began with Ultrasonix Medical Corporation where he developed and improved testing software that provided a high level of quality assurance to the medical community. Following he joined Spark Integration Technologies as an Inside Sales & Marketing representative where he implemented ?software set ups as well as developed strategic marketing design plans to increase market awareness and build an external communication framework.
Carlo Spalvieri - Enterprise Technologist - Storage, Dell
Douglas Atkinson - Vice President of Sales, TSO Logic
Douglas Atkinson is a 30 year veteran of the IT industry with strong multi discipline technology background ?with two previous start-up successes and an emphasis on customer solutions and after sales support. ?Before starting with TSO Logic, he was with Oracle storage division, CTO at Seven Group and President of Optima Networks. ?Douglas is the Vice President of Sales at TSO Logic, the first application aware performance monitoring and power management solution, and is excited by the ability to reduce data centers carbon footprint especially in variable workload environments.
Details for the meeting:
Location: Centre for Digital Media, 685 Great Northern Way ? The new building beside 577
Date and time: Wed February 20th, from 6 PM to 8ish PM.
Refreshments: Yes, there will be pizza and beer and we?ll figure out something for the few of you who are vegans. We will be going to the Tap and Barrel in Olympic Village after the meeting.
Very important: Parking: You will be given a parking pass when you arrive if you choose to park in the Center's Parking lot. There is usually plenty of free parking on the street also.

Changing MTU size on bluearc to support jumbo frames
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
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.

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.
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?On Feb 18, 2013, at 4:18 PM, Kar Hung Tom wrote:Hey guys,
