you've got a 1.66GHz Itanium 2 dual core that does 4 FP ops per cycle, so that's 8 FP per cycle at about 1.5GHz, so 12Gflop per socket.

you've got core 2 xeons with 4 cores at 3GHz+ with I think 2 flop/cycle, or 24Gflop per socket.

twice the performance, the chips are cheaper, and the architecture's orders of magnitude cheaper, although Intel's moving both to quickpath so the Itanium architecture premium would drop out to some extent, so you'd just have the excessive cost of the Itanium chip, with it's anemic performance.
*edit* 24gflops, not 14

isn't there a dual display option for the Odessey/V series?

what's your budget?

obviously you're looking at SATA. Seagate's announced 1.5Tb sata drives. in a standard 1U you can get 4 1-1.5Tb drives, so with 3 drives plus one spare you with raid 3,4, or 5 you can get about 2Tb, without the hotspare you can get 3TB-4.5TB redundant.

$225 - http://www.supermicro.com/products/chas ... T-300C.cfm
4x$250 - 1TB hdd
$115 - AM2 uATX w/1GB ram, X2 3800+
$1340 plus a 1U AM 2 HSF

the HP DL320 's an option
it would shake out to about $2,150, 1-5 year hw warrenty would be extra, and you'd have to find sleds for the 3rd party drives.

I dunno what the ebay market is on 1Us with 4 SATA bays.

depending on what internet package you get, that dual 33MHz 486 may be overkill (assuming it's got a pci slot)

couldn't you just get a replacement fan with a built in thermresistor?

they're reliable, server class hardware. if you're looking for something reliable, it's worth about as much as any other server class hardware that fits the bill.

if you're looking for bang/buck, you're looking at something that does 8Gflops. that's about it. get a quad core 2 for about $400 or so, and you're much better off, even for virtualization stuff. slap in a SATA drive for each virtual server. that said, SCSI handles multiprocess loads better.

this isn't a dropped frame here or there, this one step away from a slideshow.

I'm thinking about doing a dd benchmark piped into time to check bandwidth, lemme start up the O2 and see what error I was getting from avcapture.

"cannot set path packing: VL: bad value passed as parameter"

ok, after further investigation, the O2 works pretty fantastically at capturing uncompressed video. it's more then happy to capture full resolution NTSC to your heart's content.

not only that, it'll encode that captured uncompressed video to mjpeg at just about realtime.

what it absolutely refused unconditionally to do, is play back any kind of uncompressed full frame video at any framerate above 5fps... I should probably try mplayer, and vlc, but right now, I'm going to work on figuring out the best way to capture just the active part of a NTSC input in something like RLE, or huffyuv. hopefully 40 minutes or so on a fast 36GB, and a slow 18GB. I guess my best bet is making a JBOD with all of the 36GB, and only half the 9GB. hopefully that'll be enough.

it's about 17.5 megabytes a second. the Ultra wide SCSI-2 that the O2 uses is 16 bit, 20MHz iirc, I'm sure it's 40MB/s.

With no audio, or audio at 22KHz 8 bit mono no frames dropped, 32KHz 8bit stereo I think frames started dropping >.<. looks like 250MHz is a stretch. I can record the audio seperately I guess.

ummm, didn't the 3.16GHz beat the itanium2 in both? not as well as I predicted. also, how many cores, and sockets.

ok, I've got 50+ GB of hdd space, hopefully more friday. I'll look into working with avcapture. I was getting minimal framedropping with no audio, and xvm (with abort on framedrop it ran for almost a minute).

what advice doe people have on recording uncompressed? 720x486? the default is 640x480. should I use quicktime, or .mv? interlaced? 422 rather then apple24, or what not?

also, I haven't figured out how to do two things. record directly to the file, and how to pause without invoking the processing, which takes too long for a commercial break, which is why I'm looking at avcapture again.

right now, I'm looking at quicktime container, hoping it'll be more cross platform, 422 because it's 2bpp rather then anything that's 24 bit or more, 640x480 because it's the default full res ntsc for mediaplayer.

has anyone used mplayer or vlc to record from an O2?

Thanks. I'll try and write up something with some tips and with the helpful info people have posted.

I've got a 36GB 10K drive off the external, and a narrow 18GB where the CD drive would normally be. I made a slice at the end of the 36 that's exactly the size of the 18GB, I striped that with the 18GB then concatted that with what was left of the 36 getting about 10000000 blocks or something.

I tried to record about 20 minutes of house last night unattended, got an error.

can someone explain why the Sun Fire 280R 750MHz USIII does about as good as a 300MHz Ultra 2 on '06 SpecFP?

I've run seatools on these, they passed, they worked in windows. this happened before and after I formatted them with seatools.

ioconfig : scsi_ctlr_walk_fn : cannot open the file: /hw/node/io/pci/2/scsi_ctlr/1/target/1/lun/0/disk/volume/char : I / O error

dksc1s1vol : no sense : (asc=0x0, asa=0x0)

system logs also keep telling me reboot after reboot that it's moving config files.

I guess over the weekend I'll try them in my octane, and try formatting them in linux and then moving them back to the O2.

Does anyone have any suggestions, or experience with this?

Thanks

I get
"cannot set path packing: VL: bad value passed as parameter"
apparently the source for avcapture is on one of the dev disks, so I'll try looking at it in the near future.

fantastic, thanks a lot. let me check, I think it's a ST336752LW, but it could be a ST336732LW. I'll check tomorrow, the label is an IBM X series.

yep, ST336752lw

There's not much more I can offer, except to say that I've run into this problem before as well, and just used a different drive... Fortunately, SCSI drives of that capacity are rather cheap, so you should be able to find something else that will work.

Thanks a lot, I'll try getting the firmware through seagate. knowing that it's the firmware that's the problem saved me from a lot of fruitless troubleshooting.
