Hey guys,

We're currently using a Facilis Terrablock for our DI SAN Solution. We're working with Red files and uncompressed HD 10-bit. The Terrablock has a volume size limit of 8 TB.

Is there a SAN solution out there that can accomadate larger volumes (20 TB, etc.), while maintaining enough speed for Uncompressed HD streams? We want about 100 TB total useable storage for a small facility, 3 edit bays total.

thanks!
Elan

Our EVO solution does not have an 8TB limit as we're using HFS+ volumes for the Mac.

You can read more about it here:

Elan,

You may want to consider the 10 gig shared storage system. You can expand the drive arrays up to 128 drives. Feel free to contact me directly for more details at 714-374-4944.

Hi Elan -
are you sure that the Facilis Terrablock has a maximum volume size of 8TB ? That does not sound correct to me. Have you called Facilis ?
T.: +1.978.562.7022

or emailed them -
support@facilis.com


Our shared storage system can have a single large volume (like a single 48TB volume), but I am pretty sure that every company can do this today. I would call Facilis first, and if they say "no" - reply back here, and we will all give you the "hard sell" about how wonderful all of us are.

Called Facilis yesterday, they do not technically support volumes larger than 8 TB.

The software will let us create one, but we get Read/Write speeds below 200 MB/s on that volume, insufficient for uncompressed workflows.

As much as I love AFP and 10GbE, I have yet to see a client sucessfully impletement this type of set up for Smoke/Symphony running uncompressed resolutions. If anyone has any real world clients doing this please correct me. Yeah yeah yeah, I know it can be tested and might 'work' in a tested enviornment, but actual end users is a different story.

As far as what fits the criteria of volumes larger than 20TB in a shared enviornment that can handle these resolutions.

Cheapest - Fast FC storage with SANmp, $30k range if you cheap out on storage.
Mid Range - EVO, uses SANmp propably $50k range
High end - Xsan $80k+

Since it's only 3 workstations volume locking with SANmp is pretty solid and easy to use, especially nice with Avid since there aren't database worries.

I'm trying to get ahold of the facilis guys to, that does surprise me about the volume size limit.

SAN MP with 8Gb fibre arrays will be the easiest, most affordable route to scale that large and handle uncompressed HD. Later on, if you add several more bays, or need file-level locking, all of your arrays can be re-purposed for use with Xsan, StorNext, or ActiveSAN.

Why not have multiple volumes on the Facilis? Is it because you just want one big 'bit bucket' to use?

Facilis can scale MUCH large than 8TB, you just need to create multiple volumes.

a typical episode of the tv shows we work on have 4 to 6 TB per episode of master media. Therefore we have to create a single volume per episode to make it work.

In order to store all of the visual effects shots, pickups, etc, some episodes have to be split between volumes to store all of their media, which is kind of annoying. A 2 hour feature film shot on RED would have to have its media probably split between 3 to 4 volumes. Again, not a big deal, but it would be nice to store it all on one volume for organizational purposes.

Thats not that big a deal, it just get a bit annoying long term. It is possible we can't use larger volumes than 8 tb at the pricepoint of Facilis/Editshare/EVO, etc, we were just trying to get some guidance going forward, as I've gotten a lot of differing opinions from a lot of different people.


All of the posts on this forum, however, have been very informative.

If it helps at all... we just implemented a Facillis Terrablock and have run into the same issue with volumes being limited to 8TB. My understanding is that it's a Windows limitation on the server end. Despite being told Windows 64bit can handle any size (maybe I was lied to), it seems like the server thinks it's 64bit but behaves volume size-wise like it's 32bit. An inconvenience for sure, but I feel like half of our job is just figuring out workarounds anyways, this was easy compared to most.

Also, I've been told by the installation guy that works closely with the guys up at Facillis that they are working on a Linux based version which should hopefully be rid of all these issues.

The size limit is a pain, but I do love the system regardless. It's very fast, very easy to operate, easy to upgrade, and basically maintenance free. And their customer support is top notch.

Hi Elan. This is our setup on one of our three servers:

One Supermicro 45-bay SAS 2 (6GB) chassi, with 16 Hitachi 2TB SAS drives in a RAID6 on an ATTO R680 card, in a Mac Pro. In that Mac Pro we also have a Small Tree 6-port ethernet card, link aggregated (or bonded) to a single link. That connects to our 48 port Procurve switch, 1gb ethernet.

The raided drive is about 25 TB, with reads of about 1000 MB/S

For sharing that drive over our network we use our own software, now in beta-testing as a commercial product. Have a look at xmcorebeta.wordpress.com

We don't do uncompressed, and I suspect you need a 10 gb ethernet connection to maintain the kind of bandwidth that you need for that.. Small Tree sells those as well.. You need speed everywhere, from the RAID to the server to the switch to the workstations, so while our setup works fine for compressed HD (DNXHD) what will work for uncompressed is another story..

So setting something like this up your on your own is possible in theory, but in reality, it takes a lot of testing and time and hair pulling... But thats why you have people like Bob Zelin and others that have already done the hair pulling ;)

all the best

David
