Could you send me your contact info, as well? I would love to look at what you have to offer…and get some quotes.
Sincerely,

if you are using the Sonnet X4P on your 2 Gig G5 (and if the Lacie has the correct port multiplier chip from Silicon Image in it), you can have FOUR CHASSIS on your system, and stripe ALL of them together, if you want. The Sonnet Fusion 500P chassis, or the ProMax port multiplier chassis, that also has 5 drives in it, works great with the Sonnet X4P (and E4P).Once you get your chassis working, run AJA Kona system test on it to see your speed test results. The more drives stripped together, the faster the performance.
TWO drives (drives, not boxes) are NOT fast enough to do uncompressed HD. TWO BOXES (8 to 10 drives) will allow you to do uncompressed HD. I seem to recall that the specs on the Lacie are slow – exactly which Lacie chassis are you using. If you are not using a port multiplier chassis, you are losing capability. I know that you like ProMax, and they have a great Port multiplier chassis that holds 5 drives, that works great with the sonnet.

Right, got that. Thanks for all the other info.

LaCie S2S. We’re getting 135mb/sec running 4+1. 4 drives for media, 1 drive in backup mode.

July 8, 2006 at 9:08 pmI hate to be the nay sayer here, but if I were in your shoes, Walter, 10 or more drives at RAID 0 is not what I would do in your situation. I know I might get lambasted for saying so, but at a shop like yours where you are working all the time, overnight renders, etc etc a protected RAID is what you need. Has your Medea ever lost a drive? Even one? Imagine if that happened in your RAID 0 4TB array. All of that info is gone and lost forever and don’t forget about the downtime trying to track down the failed drive (it’s hard in ‘do it yourself’ SATA situations). Recapturing tapes in one thing, but losing valuable renders and exports is another. I know Mr Zelin has never seen a SATA drive go down, but I have been on the receiving end of it. It’s not fun to sweat while the client is staring at me as I fumble with cables and drives and have no one to call and wondering why the hell this thing won’t mount. I know there have been leaps and bounds of improvements in the SATA equipment and architecture since I dealt with it three or four years ago (namely in Sonnet’s cards), but it’s not something I would do again. I’m sure I am preaching to the choir here, but I felt compelled. SATA boxes are cheap and therefore sexy, but I wouldn’t run a RAID without parity especially at a busy shop. After I ponied up for my first fibre RAID, I have never ever looked back and said that was a waste of money.

REPLY – you will get faster performance from the Fusion 500P, the ProMax array, or almost anyone else with 4-5 drives.

You are correct in saying that working in any situation, SATA or otherwise is unwise unless you have a backup in place. SATA controllers do work in various RAID modes, the difference will be the need for more drives when doing this. Don’t be afraid of SATA just be smart!
One of the biggest features we implemented this year (finally the controllers were fast enough) was to split up our 24 drive units into 2 12 drive arrays, the renders can be dumped onto the RAID protected array, while I/O with plenty of thruput is happening on the other (simultaneously), all using SATA.
Again, it’s important to work with someone who knows what they are doing.
Cheers,

July 8, 2006 at 9:45 pmAgreed, Ramona. I had a SATA RAID from GVS that was fantastic, but it was not $3000 from ProMax. It’s has a prebuilt, pretested, hardware RAID that happened to have SATA drives inside.

I actually run RAID 0 on my Med
