Xsan vs GigE NAS?

Forums: 

We're looking at upgrading our Xsan (and all of its clients to new Mac Pros) as it's a 5 year old install and locked to 10.6.8.

I know that some places are marketing "video workflow" optimized NAS solutions over 10 gig E as an alternative. I assume these boxes just use standard AFP and file level storage.

Does anyone have a comparison of using one of those vs. Xsan? Seems like a higher theoretical bandwidth vs 4 Gb fibre (at least that's what our current switch and cards can handle)... But how does Final Cut Pro X and/or Premiere work with a file level storage system vs. Xsan? I assumed that Xsan would offer maximum compatibility for collaborating on files but I'm not sure if any changes to Final Cut X or these newer NAS boxes mitigated any issues.

LUN config for Promise Ex30 (non Apple)

Good Evening

I'm about to configure a Promise Ex30 (non apple) for an Apple Xsan Environment (Yes, Promise already confirmed that works with the hardware i have, like a Qlogic 5800, Atto and LSI cards)

I was wondering about the LUN Configuration.

The system is a 24 bay, dual controller, HDD NL-SAS of 3 TB.

What configuration do you recommend for performance?
Workflow is for both HD Full HD ProRes, and 4k XAVC (So 30 - 40 MB/s for every layer)
But i could also manage a layer of SonyRAW 4K from an F55 in 3840x2160 50p, that means 500 MB/s

2 LUN of 11 disks Raid 5 + 1 dedicated spare?
or
4 LUN of 6 disks Raid 5 without spares?

I have a dedicated metadata array 4 Gbit, cause of the presence of multiple volumes

The ALUA should be enabled for better performance? (Clients will be 10.9 / 10.8.5)
What about the stripe size?

Thank you all for your time.
