I already spoke to Nick last night cheers, Just a quick re-run as ive never ever dont it before

Both set to Master, IDE ata100 cable,Go into bios la la la set up array

Then format into 80gb drive. FDisk 70gb/10gb 2k /Linux

Then Boot from CD Rom, go into 3rd Party RAID controller at set up?

anymore info

at moment my hard drives rated 657 on PC bench test

IS it worth doing

Cheers

Si

suba

what are you trying to acheive? speed or capacity?

super_si

capacity's a bi product

Speed ideally
more space to download

Si, as I said, the performance differs severely depending on what drives you pair together, like I showed you in those striped performance benchmarks comparing 4 commonly available drives today.
Ideally, you should have the 2 identical drives on the master of each Highpoint 370 channel, fire up the pc, do ctrl+h to get into the BIOS, make sure that both drives register.
select create array, give it a name, such as WD_RAID or whatever,
select RAID 0 then select the 2 disks, set the block size to 128k, as this produces the optimal general performance with the 370 controller.
Once this is created, then select hdd1 as the boot drive and the other will appear as hidden.
Reboot, and at the beginning blue screen press f6 when prompted.
when asked, install the highpoint drivers off floppy that correspond to the highpoint BIOS version that you have. Once this is done, you will be presented with your drive and partition it as you feel.

Just remember, you may not get a huuuge increase in speed and the risks of complete data loss are doubled by striping the drives, as if one goes, the data on the other makes no sense.....

Saying that though, my current IBM setup absolutely kills a 15K rpm SCSI160 drive
The avg result on Sandra for a SCSI160 15k drive is about 40000K/second, my twin IBM consistently produce above 54000K/second

Config:

Epox 4g4a+mobo
Intel 2.2 Northwood
1024MB Samsung (super) DDR333 RAM
Integrated Highpoint 372 ATA133 RAID controller
Twin IBM 120GXP 60gb ATA100 7200rpm drives, striped 128k blocks, NTFS.


Cheers,

Nick

super_si

you little **** lol


No wonder you won!! you wait my son! I got rating 4992 of for Memory lastnight!

Abit Th7 II Raid
P4 1800Mhz Northwood CPU
2*256Mb Samsung 800Mhz RD RAM
2*40gb W.Digital 7,200RPM UTDMA ata 100drives

thats what id forgotten to ask!! I was going to leave it HD0

Also Did you manages to get those BIOS drivers to put no Disk mate?

Cheers nick

I can say that they kill SCSI160 as I also run 3 15k rpm SCSI drives in my server

super_si

in my server i have blag blag blag blag blag

Show off

David_Wallis

hmmm, wouldnt mind benchmarking my server...

600gb FibreChannel Disks... Oh and this really does get some through put... Hammers its gigabit connection without a problem!

David

Mr Footlong

iTrader: (7)

Is that your home one though?


You will probably say yes, no doubt!

Cheers,

Nick

super_si

Sounds a beast! must cost a canny bit technology like that!

Never really seen / Come across it

What specs thats Blue Mountain PC in California?? Think its Compaq or the IBM one im thinking off

Si

IWatkins

My pair of Crays will take you all on... right up until we get our new NEC superduperputer.

OK, not at home, but I can get to them from home.

Cheers

Ian

super_si

isnt the cray out dated now?

IWatkins

Nah, in the right configuration, some of the Crays are still one of the fastest supercomputers around when you include throughput of data.

Raw processing speed (as quoted on Top500) doesn't mean anything unless you can get the data in, get the data out and store it, non-stop, 24/7/365 as we do.

Saying that, we are switching to NEC as they had the bid we liked.

New NEC system will initially be 6 times as powerful as the combined power of our current Cray T3Es, rising later on to over 12 times as powerful. Bet it still won't be enough

Cheers

Ian

David_Wallis

what do you do ian??

This is just the storage for one of our main clusters, Just fitted a fc/scsi bridge on it is that quick or what...

(all compaq)

David

dsmith

We have four NetApp web caches out of support soon that are coming back to our reference model. Each one has a rather tasty Fibre Channel disk shelf - complete with PCI fibre chanel card you can whip out the NetApp appliance and plug into a windows server.

Got my eye on one for home, and a couple for the MP3 store at work

Deano

IWatkins

David,

I work for this lot, http://www.metoffice.com/, and yes, it is my fault the weather is wet/snowing/sunny/too hot/ too cold etc.

I don't actually know too much about our installation as I'm only really a user of it, but I do know we have a quite big IBM mainframe to look after the two Crays, all linked together with some fast interlinks called HiPPIs, whatever they are.

More info on our main system: http://www.metoffice.com/research/nw...ers/index.html

Cheers

Ian

MrDeference

I am fascinated. What do you guys do at home which means you need computers with that amount of power?

dsmith

Errr Play ?

MrDeference

Oh - silly me. Now I completely understand

David_Wallis

600gb is 1 of the work cluster...

at home I have

Athlon Thunderbird 1.1ghz
1Gb Ram (133)
Soltek Mboard
ATI All in wonder Pro 16mb (iiyama 19" Vision Master Pro)
Cirrus 8mb PCI for second monitor (Phillips 17")
SCSI CD Writer + CD Rom
2x 30gb ATA100 Disks.
Internal Zip Drive

and dont play any games!!

David

super_si

Dave could you bench mark the Hard drives, just out of interest!



Wheres the Monitor and Disk Drive?!?!

David_Wallis

Si, if I knew you wernt being serious about the keyboard and monitor then it woluld be funny... and those machines arent really about Disk I/O

David

super_si

was it the that gave it away.


But serious, What are the used for?

Like i said earlier, Isnt one 1-2 in California, Big Blue or something, Isnt that the most Powerful Comp. going

Si

IWatkins

Nah, most powerful nowadays is the NEC Earth Sim.

Take a look here Si, for some hardware that kind of makes even the fastest PC sound like it is switched off http://www.top500.org/list/2002/06/

Cheers

Ian

super_si

How that going to compare when they eventually get the Quantum PC's working?

Did a paper on them last year i cant remember if they had one working with just 2 inputs of data or something. Long time since i read about them
Can remember that they go threw every possible route to a problem , which is quicker!

Si

super_si

i chose 0,

should it have being [0+1]
