Have anybody else apart from Mark Patrick used raid card from RaidCore with SATA Raptors?
If you did can you share your experience with us? Interesting to know your system configuration, all specs etc.
Any input very appreciated.

Buying VT[3] soon.

Bandwidth of up to 150MB/sec is possible using the configuration you posted!

I would like to see specs of the system that worked with RaidCore. I heard that not every system would work.

Thanks for reply

It was an 875-chipset motherboard with the integrated Raid (-R designation) Serial ATA controller.

Paul,
Dmitry isn't referring to an Intel SATA/native-chipset solution. His requirements are for a statement of which motherboard supports the RaidCore vendor's rare parallel processing SATA controller (same vein as the 3ware escalade). There must be someone out there who knows or is about to find out.....

Could be that the answer to his question is any one of:

SuperMicro
P4SCT (single PIV, i875 / limited PCI-X / 6300ESB)
X5DAL-TG2 (Xeon, E7505)
X5DCE ( " " + more slots, RAM and housing requirements)
X5DA8 ( " " + onboard U320 SCSI)

I-Will
DP533-S (Xeon, E7505 + onboard U320 SCSI)

I don't think RAIDCore is currently being integrated onto motherboards as onboard peripherals. RAIDCore products appear to be as hard to find as hens teeth, or at least last time I looked that was my finding. Which model of RAIDCore were you considering dmk75?

Dimitry, I would recommend you consider approaching a dealer. Even if you already have bought your VT directly. If you are sure that you can purchase your host system cheaper than they can. A dealer would still offer more than a solution in that they wouldn't walk away from the deal post sales. Wherever you are located. These folks are the salt of the earth and I don't personally benefit a smidge by telling you that.

Ok, it happend!
I bought VT[3] and I ordered system parts following:

VGA ASUS V9570/TD/256MB
MB E7505|MBD-X5DAL-TG2 SuperMICRO
CDRW LTON|52X32X52 LTR-52327S
CPU INTEL XEON 3.06G 533M 512K (Qty=2)
DVR|PIONEER DVR-107 BLK DVD+/-RW
HD 250GB|HITACHI SATA 8MB
HD 74GB|WD 10,000RPM 8MB WD740GD (Qty=4)
DDRAM 1GB PC2100 | ECC REG -K RTL (Qty=2)
MNTR BENQ|17"LCD FP767-v2 B/SLV (Qty=2)
CASE TT|10 ATXF XASER III V1420DU
RAIDCORE RC4852 4000 SERIES 8 CH SATA RAID CONTROLLER

As soon as I have it build I will post the results of that experiment. Now I'm officialy joined NewTek community.
Can anybody give a link where to get Benchmark tests software for a SATA raid? I want to give some numbers to people.

I tried the Raidcore 4 drive model for a large Matrox system a few months ago but didn't get to try it with a VT.

I did benchmark it though. The results showed great single file throughput, but on multiple reads, like for the VT, it fell on it's face due to latency issues. Slow seek times will make a VT stutter QUICK.

For DV only, it might work great and be dirt cheap. For DV and very light RTV use, I've had good luck with onboard SATA with software striping using as few as two drives.

Just know that you will be trading off layers of uncompressed for the dollars saved using any non-SCSI solution.

To VT Owner:

What Kind HD's did you use with RaidCore? What are computer's specs? Did you use PCI-X 133 Mhz for RaidCore controller? What RAID type?
I'm very interested in RaidCore Controller.

It was a Supermicro X5DAE dual Xeon board, so yes, it was in a 133Mhz PCI slot.

We used 200GB WD JB drives. The 7200RPM drives don't give quite as good performance as the Raptor 10,000RPM drives but it isn't a huge performance gap. IMHO at that point the Raptor drives cost enough to just go ahead and get SCSI (and WAY faster speeds) instead.

I used RAID0 during my tests.
