Purchase and use R-Studio. Works well to recover raids.

So I did some quick maths as a “for example” of what it would cost to host 3TBs on Amazon S3… it’s about $390/mo… Seems maybe a bit high, but it would be fast and accessible. You could do something like Backblaze (unlimited desktop backup service) that’s only like $5/mo but it will super slow. If there was something in between, what would you be willing to pay monthly (per TB?).
Alternatively you could rent some space at a data hotel, throw a server in there, etc., but then you have to also worry about backups, server admin, etc.
A big question also is of course what size files are you working with and what kind of time do you have to send/receive them?
My company has some really good cloud storage available that we could possibly resell if it suits your needs, or maybe some other service could be recommended.
The big question is of course the Bob Zelin factor, “DO YOU HAVE A REAL BUDGET? IF NOT GO HOME.”

Bob, you would think that 30″ would be enough, but imagine my surprise when I received the NexSAN SataBeast Expansion (60 drives) to find out that it’s actually 40″ deep. It didn’t fit in my rack and I had to return it and swap for an extra head unit (42 drives). More throughput but less storage…
I believe their new e60 is 40″ deep as well.
40″ deep is like a toboggan…

Here’s the link to my spreadsheet:

Good to hear from someone who has been around long enough to see many generations of this… It’s helpful to have both experience as well as the math behind it showing that it makes sense to do this.
Of course the other piece of the puzzle is having good data-retention policies, but that’s a tough one to sell as well.
Bob, my thought is to make sure to be up-front with purchasers about this — and maybe even push for leased storage so that they get in the routine of renewing every third year. It’s helpful if they already have it marked on their calendar, “THIRD YEAR, TIME TO GET NEW STORAGE TO SAVE MONEY.” Also it’s helpful when purchasing — this purchase doesn’t have to last you forever, just for 3 years.

Sounds like fun. And by fun, I mean, “kids, don’t try this at work.”
If you’re gonna go for this, here’s what you could do:
1. Buy your crazy IB switch on eBay, if it comes with cards, use them on Windows/LInux hosts
2. Buy IB cards for the macs from someone who makes them for mac, like Cal Digit (not sure if they will sell individual cards, but you can try). Not sure it will be compatible, but hey, you’re a risk taker, right?
3. I guess you would have to share it out using SMB or NFS, or use MetaLan or StorNext…That *could* work, but unless you’re just a crazy guy with time/money to burn, I’d go with a regular solution, either with 10GbE or Fiber.

Argh, I’m another victim of the upside down breakout cable… BAH!

So I think I’m understanding this a bit better, but things still aren’t working for me. Restating the situation:
Doing a multi-cam event, using a Ross Switcher. Need to capture and playout using AJA LHi. For capture, I need to somehow embed the timecode. We have an Everts time clock generating timecode which is fed to the switcher (works fine there).
From what I understand, with AJA my options for receiving the timecode are:
1. Via the LTC Serial Port
2. Via the SDI feed (embedded VITC)I have tried getting LTC on the serial port but so far that has not been successful. I do have a VITC feed from the evertz, but I don’t know how I would embed that onto my video data stream.
Also, for reference my two options are:
1. Use the reference port. Because we are shooting HD, I need Tri-Level Sync? SD Black Burst wasn’t working… I’ll try Tri-level later tomorrow.
2. Use my video input to sync — This works.Always learning more…

We have an Evertz Master Clock 5600 feeding reference/tc over BNC. I have this plugged into the Ref port w/ 75ohm terminator on the loop end. I have it set to RP188 VITC 1 for timecode. In the control panel, I see “No Video”, and no sync/timecode coming in.
I read in the manual that the source ref needs to be same definition as your output, is that true? I think my sync is only SD. I can sync via our SDI In I think, but I really need time code to work. If this doesn’t work I’ll have to monkey with the LTC stuff.

Hey there. Fellow non-profiter non-sales guy here. I’m currently installing “100+ TB” as well, and I can offer some advice, and also a referral.
Obvious things to consider:
How many clients connected? What bit-rates are the video files accessed? Can you estimate a total aggregate bandwidth maximum you think you might need (Clients X Bitrate X Number of Streams Per Client Concurrent?) Also you COULD consider tiered storage, but it’s not ALWAYS cost effective.Also, I would recommend something you feel comfortable supporting — if it’s in-house, make sure your staff gets trained properly. If it’s out-of-house, make sure you have a good relationship with the company. Generally it’s a bit of both, so do both.
That’s the basics.
What should you get? It always depends on your environment. Personally I really like Active Storage’s new MetaData Servers, and I like Active Storage or Promise for Tier 1 high speed storage, and NexSAN or LSI (netApp) for Tier 2. Or you can go with Tier2 all the way if you don’t need real high speed.
NexSAN just announced a new super-dense system with 60 drives in 4U… That’s 120TB! 4x8GB fibers, AutoMAID power savings… that might fit what you need. Add an expansion later if you need more 🙂
Here’s a referral to a friend of mine I’ve used, he’s based out of Cambridge, Mass. He also has a really smart engineer on hand who helped us find the right solution for us.
