  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

I found recently that a RED ONE reservation holder here in Belgrade (Serbia) is producing possibly fastest 4T HD raid in the world. According to Pop (system integrator) his raids are faster then Huge media vault or Apple Xserve raids significantly. MACOLA (brand name) working with infiniband interface on Mac G5 Quad 2,5 GHz with 2GB RAM are giving speed test as shown in the given screen shot. Pop is selling this raids also for prices much below competition. He is going to use MACOLA with RED ONE camera and Mac for editing footage of independent movie production here in Serbia.
 
Uhm... Blackmagic Disk Speed Test is nothing I would use as diskspeed benchmark though.. I get very odd results with their disk speed testing utility myself, not far from the "Macola" numbers.. In real life my dual spanned raid controller perform aint close to those black magic numbers...
 
Thanks Milan

Interesting - do you know what is their reputation for reliability?
 
what this RAID?
RAID0?
RAID3?
RAID5 or RAID6?

you can it created themselves RAID system on MacPro and HighPoinT RocketRAID 2340 16 SATA II ports - capacity 12 TB (on 750 GB drive) - RAID 0 speed (i think so) 900 - 1050 MB/s

use 250 GB hard drive - capacity 4 TB - speed not changed
 
Yeah, too many questions here...

BlackMagic disk test is a poor way to actually guage performance. Not that it matters, the ~550MB/s shown on that blackmagic test image is nothing special. I've got RAIDs that blow right past that built out of 3Ware SATA-II controllers and 74 to 320 GB drives.

XServe RAID isn't exactly an example of ultimate performance either... Lots of options out there that are a lot cheaper and a lot faster than XServe RAID. I own a 7TB Xserve RAID (14 x 500GB drives). Honestly, I would have never even thought of owning one had I not stumbled across this unit bundled with the FC PCI-E controller on ebay for less than $4500 that I could pick up in person from the seller - And that was several months ago... At the time, it was like buying the 14x500GB drives and getting the RAID enclosure and FC card for free. :D

Milan,

Sorry to burst your bubble, but unless I misunderstand what you're posting this is far from the fastest RAID in the world. Most of the systems that our customers use are doing sustained disk reads at about 800 MB/s, and writes at about 500 MB/s.

We have a few customers that have RAIDs that can do sustained reads at >1.2GB/s. (that's gigaBYTES)

Some additional information on MACOLA HD raid,
You can see it on web site: [U]www.mac.co.yu/ponuda/macola/macola.html[/U]
but, sight is on Serbian language. You can send them e-mail to ask for information in English for sure.
RAID is 0, 1,5, 10, JBOD, automatic reconstruction after replacement of faulty HD, write-through, write-back cache support, hot swap and hot spare on-line capacity enhancement, on-line RAID level migration, etc.
Prices are: MACOLA 4T 5,650 Euro and MACOLA 3T 2,300 Euro if I am not wrong. It is 5 years guaranted.
 
1 st he needs to run the AJA test with Disable file system cache checked.. otherwise the read is from ram.

The spikes are somewhat like mine.. thats our issue with our current raid. but were testing a new HBA in the morning.

Also he could do with selecting full HD 1920 1080 4:4:4 or even 2k rather than the little 720x486. The spikes will drop then and you'll get a better picture.

I agree.. nothing special.. our 8bay sata does 600MB/s now.. but thats empty.. but spikes as low as 50MB/s with the old HBA and gave us dropped frames.

Can anyone suggest a proper disk test app for OSX?

and where on earth on the macpro is this single infiniband going in :-/ not on a card... wheres the slot :-/

We would like to try proper disk test under Mac OS X also,
any suggestion ?

Pop
 
what do bearfeets website use?

I know ATTO have a disk test but I believe you need to purchase it.. it certainly never came with our ATTO card.

Run the AJA with a console open. The reported data rates in the app are lower than those reportd in the console. which goes with what others have suggested elsewhere that it gives some give in the data rates compared to the BM app.

Also the aja test will change the second time you run it.. but 3rd will match the 1st.. 4th test will match the 2nd. Something not quite right there.

BareFeats use Disktester..

this is what we are running currently.

That price/performance ratio looks really good.

I have a HUGE 4210 and it is a TANK! HUGE is also very selective about the drives they place in the RAID. If the drives do not pass very strict testing they are FAILED for use in this raid system. They are not 'Off the shelf" sata drives.

That said, I have had a drive in the the raid 3 mode fail. HUGE had a new drive to me the NEXT DAY. I'm not sure they'd offer this type of service via FED EX from Serbia.

While these tests seem impressive, have the tests been done when the disks are at 25%, 50%, 75% and 90% capacity. Evrything is fast at raid 0 and empty. it's important to know what happen when the drive fills up.

It's pretty hard to be making the claims you are making here against a VERY reputable manufacturer of High speed disk array systems.

wow,
that is the fastest read speed I've ever seen on a 16 drive raid array. Thats fulll utilization of every disks speed. How about Raid 1,5,6 speeds ?
