ACARD/SSD vs. 1Gb/10Gb Ethernet

Hi Performance Testers, having done SSD test I was curious to see how Onyx350/4 did on NFS share via Gigabit Ethernet (1Gbe). The NFS server is 8 Core Apple Xserve with 10Gbe to 10Gbe switch and then 2x1Gbe LAG groups to 1Gbe switch: So have: <XServe + 10Gbe> <-----> <Netgear 10Gbe Switch> <--2x1Gbe...

Octane2/Onyx350/4 - ACARD ARS-2160H/ARS-2320S with Samsung SSD

Hi Performance Testers, quite some time ago I swapped out SCSI HD from Octane2 and replaced it with ACARD ARS-2160H with SAMSUNG SSD (EVO 840 250GB). Since I got Onyx350/4 boxes I got a couple of additional ACARD ARS-2320S adaptors and put SAMSUNG SSD EVO 850 1TB in each of these and also updated EV...

Re: Maintaining Hardware / fesability of keeping hardware running

Hi josehill & venomousepinecone,

ha ha ha ... as a poor sod with a physics degree, I have to admit you are right. We have been battling against entropy in parallel universes.

But the ignorant practical biologist in us refuses to give up the fight ;-)

Cheers from Oz,

Re: Maintaining Hardware / fesability of keeping hardware running

Hi Nekochaners, whether old machines are worth maintaining kind of gets to the “What do you use <xxx> for ?”, where <xxx> is your favourite old machine. Compared to some on Nekochan, I am modest collector. I have kept Octane2 in mostly working order, though at one point I stripped the entire machine...

Re: Dammit

Hi Jan-Jaap, Read a few threads on Dallas chip expiry issues. Is this SGIs equivalent to vintage Macintosh leaky capacitors? Not a matter of if it will fail, just a question of when it will fail. I have had to get a few Macs recapped and have another Color Classic that will have to be done at some p...

Re: SGI Origin 2400 Rack cabling help

Hi docz, just in case you were not aware... The sgi techpubs materials are archived at: http://www.irix7.com and the SGI materials are essential reading for getting any of more complicated rack systems up and running. see here for example (Origin2000 Rackmount Owner’s Guide): http://www.irix7.com/te...

Re: Origin 350 No L1 or Console

Hi Philb, I have just been through major exercise in getting set of Onyx4s up and running. To get everything stable on mine I had to: 1. Get all L1 sw versions in sync 2. Get all serial no lined up 3. Get brick/rack ids defined 4. Do set of IRIX installs/upgrades from 6.5.21 to 6.5.29 (as a result o...

Re: C-Ray FP/CPU Benchmark Test Results

Hi Ian, yes it is a bit of fun running these... and I am pretty good at spreadsheets, so easy for me to do. Agree SGI and MIP a great case study in what could have been. Realised that I put scene/7500x3500 on graph when I should have put sphfract/1024x760, so here are numbers for that set of tests: ...

Re: C-Ray FP/CPU Benchmark Test Results

Hi Ian, After reviewing results I thought I should try additional thread counts, so have updated script to do: 1,2,4,8,16,32,64,128,256,512. Hold off loading updates until I upload more comprehensive set of thread counts, expect this will show Octane2 thread behaviour variation better. Here are upda...

Re: C-Ray FP/CPU Benchmark Test Results

Hi Ian & Co, came across the c-ray benchmark and thought it would be interesting to see how my recently revived Onyx 4 did, but while I was at it I was interested to also see how old SGI performed relative to classic Mac Pro (Late 2012 with 12 3.46GHZ Cores). In summary, running all tests with m...

Re: Onyx/Tezro - Error: ERROR: SCAN:scan error - unable to reset scan hardware

Hi Nekochaners, good news! (for me anyway ;-) ) . Today was holiday in Australia (Melbourne Cup) and so after mostly inconclusive testing with L3 software diagnostics I decided I may as well complete IRIX update to 6.5.29 and apply corresponding new l1 software to 4x1GHZ & 4x800MHz chassis's. IR...

Re: Fuel R14k cpu into octane1 ?

Hi ssch1034, when it comes to old SGI gear and Nekochaner's sometimes it is just to see if it can be done that provides motivation rather than rational reason. But this one falls into the way to hard basket. I think one of the complications of MIPS architecture is the caching implementation, which i...
