Please post your 'hinv' in the following format:

Topic: Kind of machine (O2, Octane, Tezro, Onyx2, etc.), CPU (R10k 250MHz, R12k 300MHz, R16k 1GHz, etc.), RAM, graphics option (Example: Tezro V12 4xR16K 700MHz 4GB)

Body: output of hinv -v (hinv -vm if possible) and /usr/gfx/gfxinfo.

Please wrap the output in BBCode "code" blocks to improve legibility.

08/Oct/2012 Edit: Replaced the system disk with a 60GB SSD (OCZ Vertex2E) in an ARS-2160H 68pin SCSI/SATA bridge box, but /usr and /var are
stored on a separate 120GB OCZ Vertex2E connected to the SAS/SATA card, thus allowing max speed for all accesses to those areas. This gives
the following diskperf when run within /var/tmp:

I'll update the pictures later.

Meanwhile, I'm not using the DDS4 DAT or external 146GB SCSI disk anymore (got a new backup system, more on that later), and the external CDRW
isn't connected now either. And I've replaced the 3041X-R SAS card with a 3442X-R, so the system now has a 4-port external link aswell (this relates
to the new backup setup).

28/Feb/2011 Edit: Upgraded the SAS to a 600GB 15K (same model generation).

03/Jan/2011 Edit: Replaced the 300GB 10K data disk with a Seagate 450GB 15K SAS (15K.7). Moved my main /ian user account (approx. 67GB
of data atm) onto a 120GB SSD (OCZ Vertex2E 3.5").

31/Aug/2009 Edit: Replaced Maxtor system disk with 300GB 15K Fujitsu, replaced LSI 22320 SCSI card with LSI SAS3041X-R
SAS/SATA, added 1TB SATA disk.

Here are some diskperf results on the drives, done with all background processes running as normal, ie. mediad, httpd, firefox, etc.

0,1: OCZ Vertex2E 60GB 2.5" SSD. Current "system" disk (test must be executed somewhere such as /tmp, as /var and /usr are on a different device).

Reference info: RAID results using one dual-channel SCSI card, comparing LSI 22320 to QLA12160/66, tested
with Maxtor Atlas 15K II 146GB disks:

Code:
Summary for 'n' disks on 2 channels, optimised for HD video, fwd read/write speeds only.

         | **FORWARD WRITE** | **FORWARD READ**
         |    LSI     QLA    |    LSI    QLA
-----------------------------------------------
2 disks  |  172.02   172.76  |  159.08   159.26
4 disks  |  209.30   266.74  |  186.62   237.78
6 disks  |  209.36   269.59  |  190.81   245.07
12 disks |  209.30   269.34  |  200.07   260.37


Except for using two disks, the QLA is significantly faster than the LSI.

Cheers! :)

Ian.

PS. For an Alias render benchmark I've done (complex scene), this system beats a dual-600 Octane2. For a simple scene though, the
Octane2 is faster. The more complex the task, the better Fuel and O3K systems run. I've accumulated data for dozens of systems, results
now available on my site!

Sweet system! Lucky b*stard...

The 900Mhz R16K must be rarer than hen's teeth... how did you manage the score?

I suspect Ian's answer might begin, "Many Bothans died..."

(40Kbit dialup - yuck!!...)

I did a swap; my two Fuel 700/V12 systems for a 900/V10 and an Onyx2 deskside, and helping
with some other stuff.

Cheers! :)

Ian.

PS. Bothans?... It was a slaughter... >-)

Will do! Some time in January.

Hope you all had a good Christmas, etc.!!

I've finished doing the usual benchmark tests from my SGI General Performance Comparisons page (Inventor, GIMP, etc.),
and also Quake1/Quake2 tests (finally worked out how to run the tests single-buffered). I've also taken a few pics,
though the lighting/sharpness isn't all that great as the system lives under my desk, so natural light is mostly absent.

Are you open to trades? How do first born sons sound?

Nah, somebody just worked their butt off. :D (ie. me)

Ooo, you'd have to do way better than that... would be well into the Lex Luthor scale of things. :D You know,
as in babes, Australia, The Universe, that sort of thing...


Meanwhile, as a final closing treat for 2008, I've just uploaded the results of of my latest benchmarking venture,
namely running Alias and Maya renders using two quite different scenes (complex scene with Alias, simple scene
with Maya; links are on the left hand side in the index frame):

http://www.sgidepot.co.uk/perfcomp.html

or if you don't want the frames layout, here are direct links to the Alias and Maya pages.

Hope you find the results interesting! Main thing to take away from the data is that, in general, rendering a complex
scene will scale much better using multiple CPUs on an O3K-class system, though the Onyx2 does rather well.

That's it for this year! Catchya next year... :D

Ian.

Very nice Ian!

If I'm ever up in Scotland (But why?! It's colder there!!! 8-) ) I'll have to pop in and see this beast!

Happy New Year!

(What's next, a quad 1ghz Tezro?)

A quick bump to help spread some useful info:-

I've replaced the LSI 22320 card with an LSI SAS3041X-R SAS/SATA card, and installed a 1TB SATA, so now my Fuel has
a 1TB SATA to act as a backup clone/copy of my movie archive disk in my PC. Here's a df (oh yeah, I also replaced the
146GB 15K Maxtor system disk with a 300GB 15K Fujitsu MBA3300NC):

Code:
Filesystem             Type  kbytes      use        avail   %use  Mounted on
/dev/root               xfs 292799884  124513248  168286636  43   /
/dev/dsk/dks10d0s7      xfs 976641304   64263012  912378292   7   /video
/dev/dsk/dks0d2s7       xfs 292930940  272496640   20434300  94   /disk2


I've not yet finished copying the data over to the SATA in the Fuel from my PC, but it's pretty quick via ftp, about 75MB/sec.
An intriguing test given that the both the source and destination for this transfer is exactly the same model of drive (Samsung
Spinpoint F1 1TB 7200rpm SATA, model HD103UJ). Would be interesting to see how two of these operate as a RAID0 with
a Fuel, but that's for the future.

The SAS3041X-R just has 4 internal ports, but it's quite cheap and thus ideal for installing SATAs in a Fuel. Also note that
using the fastest possible SATA (WD VR 10K series) does work fine with Fuel/Tezro and the performance is good, beating
all SCSI 10Ks and most SCSI 15Ks (see my disks performance results page), though 2nd-hand prices are not quite as good
as 15K SCSI. OTOH, the WD VR makes less noise, uses less power and generates less heat.

I'll update the hinv, etc. in my o.p. shortly.

Ian.

PS. Am hoping to be able to test an SSD in October.
