O2 Hardware FAQs:

1a. Can the O2 be upgraded to permit faster SCSI transfer speeds or am I stuck with the inbuilt SCSI only?

colin wrote:40 MB/sec UW SCSI should be plenty fast for even a new drive. Honest. Find a good deal on a recent 18 GB 10K RPM drive. The original 4 and 9 GB drives are 7 or 8 years old now and are SLOW.

If you want something faster, stripe 3 new drives: one on the internal bus, one on the external bus, and one on an Adaptec 2940WU PCI card. You should be able to hit 90+ MB/sec sustained with 3 modern drives.

1b. Some useful SCSI tips:

traktopel wrote:The O2 scsi HBA is Single Ended (SE) SCSI and IBM drives are LVD. It might be not only a SYNC or NEGO issue but due to LVD to SE conversion .
I have heard that the Adaptec chip and IBM DDYS drives might have troubles in some cases.
I know I should not say that be if you have a PC with an Adaptec 2940 you can test the same config and might not work as well…

Check if drives have a “Force SE mode” jumper….

ShadeOfBlue wrote:Be sure to enable parity on any drive that you intend to use in an SGI. Most drives have a jumper and some can do it by themselves

LoWeN wrote:Be aware that U320 harddrives are not compatible below UW.So it will workwith octane/O2/O200…

hamei wrote:A reference point for people worried about heat – just swapped a 10k rpm IBM DDYS drive out for a 15k rpm Maxtor Atlas (not even Atlas II) and the newer faster drive runs cooler than the older slower one.

zahal wrote: Upgraded my O2’s 36GB 10k.6 to a 72GB 15k.4 drive 2 days ago. Works great, there’s a hum that I don’t recall with the 10k (seems like the O2’s plastic case is resonating with the 15k)… Gimp and Fireflop now startup quite faster….boot time is also reduced.
I recomend O2 owners to upgrade to a 15k.4 if possible (or any good 15k drive)….any speed boost on the bloo toaster is appreciated

2. Hey! My CD/CD-RW/DVD/DVD-RW drive reads media just fine, boots IRIX CDs just fine too. I can install, copy, stretch + flex stuff around but I can’t play an Audio CD! WTF?

Tough cookies: audio-over-scsi is realy idiosyncratic and so far only known to work with Toshiba drives

radrob wrote:Ga53n wrote:foetz wrote:i used a plextor 40x with r5k and r10k o2s. always worked like a charm.

Is it possible to mount a Plextor 40x CD-Rom in an O2 case, and will the O2 boot from it?

yes of course, i changed my broken original toshiba witha plextor 5 yrs ago you can boot from and do all you want..except audio-over-scsi
for that you need a toshibas

3. Can I dress my O2 with a DVD-ROM? Can I play a DVD movie on my O2?

unixmuseum wrote:What kind of DVD movie? If it’s a regular, off the shelf movie bought at a store, then no, you can’t read that on IRIX as there is no decoder to my knowledge… If it is a non-encrypted movie, then mplayer would do a terrific job. I would go with the DVD that sgi used in their later O2 models, i.e. Toshiba S-DM1401 as it is also perfectly IRIX bootable and fits nicely in the O2 case…
vegac wrote:I’m going to wager that you will most likely NOT be able to watch DVD movies… mplayer would be able to play non-encrypted DVDs, but the super-high bitrates just makes them very choppy.
Work in progress for the software that’s gonna make your hardware ready to tango here: MPlayer

4. What about SCSI-IDE Bridges?

1. LG GSA-4081B Super-Multi – DVD±RW / DVD-RAM in O2
2. SCSI->ATA Bridge Questions
3. AEC-7720UW Ultra Wide SCSI-to-IDE Bridge, confirmed by Arti77

5. Is FireWire really working? What is supported so far?

Tough cookies (again): most people had no luck, some got storage devices (HDs, CD/DVDs) working but not DV/MiniDV transfers. Hear here and here

6. Yeah right, internal HDs are fine but I want big+fast scratch disks. What about external storage options?

1. Most nekochaners agree that Fibre Channel is the best bang for your buck, a lot of (aggregated) info is here: External Storage Options for O2.

2. Chris Kalisiak [The Keeper], has writen a Fibre Channel FAQ for SGI users, can provide you with custom FC solutions and answer your questions on all things FC.

3. Chris Pirazzi’s Lurker’s Guide to Video has a wealth of video-related information for SGI machines (including sections dedicated to disk requirements for video, O2-specific info etc). Just a quoted excerpt here (as a starting point), reading his pages is (more than) recommended.

Lurker’s Guide to Video wrote:O2 systems come with two single-ended ultra SCSI busses. The internal bus serves the CD-ROM and two internal 3.5″ drive bays with SCA connectors (one bay on the R10k O2). The external bus is available on a “68-pin high density” connector. O2 also has a half-size PCI slot which you can use for an additional ultra SCSI or other interface card.

Several SGI developers and customers have successfully recorded and played back VL_PACKING_YVYU_422_8active-region uncompressed video in the 4 major video timings (17-22 MB/sec) using only the O2’s external ultra SCSI bus.

An official SGI-supported disk solution for uncompressed video is to chain together four SGI 4GB or 9GB disks and plug them into your external SCSI connector. Here are the SGI part numbers:

We have found this combination to work reliably.

7. What about the PSU fun? Is it safe to disconnect it to silence my o2?

Everyone thank Harry (deBug) for taking the time to run some tests and come up with an answer for this vfaq:

deBug wrote:Note about power consumption:
I tested my power consumption on my O2 to be able to determine how much cooling was needed. Here are the results:

My computer had 8x64MB Kingston memory for a total of 512MB.
They seem to generate their faire share of heat.

O2 300MHz R5200 with 10k RPM hard drive, No camera
84Watt hard drive and CPU working max
79Watt CPU max, disk idle
74Watt CPU and disk idle

Same computer with 600MHz CPU
O2 600MHz R7000 with 10k RPM hard drive, No camera
83Watt hard drive and CPU working max
78Watt CPU max, disk idle
73Watt CPU and disk idle

+5Watt if camera plugged in.
9Watt at Standby.

So it seems running with out the power supply fan is not possible. 80 W needs to be ventilated.
I have installed a fan controller and lowered to about half the original RPM.
