Has anyone ever got the netcell sata 5 port cards over 2 terabytes in volume?
I have 3! of the cards, in the aim to create 3 4tb raid3 volumes, using 1 tb drives.
With the 5 drives connected, the firmware sees and creates the raid3 volume. But once you boot, all you get is a 2tb volume, and an unknown device in device manager.
Its not a windows problem, this is server 2003 standard edition!
If there is no fix i have two cards available to sell, because one of them is in a machine using 250 gig drives that i had laying around.

is it possible that the drives are SATA3.0?  If so...have you tried to throttle or limit the throughout speed down to 1.5? Some newer SATA drives require a utility to do that..while others have jumper settings that allow for it....keeping in mind that for example Western Digital refers to that throttling back as "opt1" instead of clearly stating what that jumper does. Perhaps you could let us know what drives you have.....of course you know that these Netcell cards are limited to 1.5 thru put. |

I remember see something on the other Netcell site (www.soft-port.dk):
"Q: Support for partitions over 2Tb
James M wrote the following question:
Do you know if these cards support a volume/partition over 2Tb in size? I have 2 of these cards and just purchased 5 750Gb western digital sata drives and want to make one large partition. I tried and it seemed to create the array fine through the initial set-up before booting, but when I get into windows (2003 server), I only saw a drive that was 698Gb in size??? It was set up as raid 3 automatically since I used all 5 drives.
A: I got this answer from a former NetCell employee.
Yes, the card should work.
I have a video server set up with 5 - 500 GB SATA drives.
However, I believe that Windows XP home has a 2TB file system limit (2^32 512 byte sectors)."
Unless I'm wrong Sever 2003 is 32-bit system. I hope this helps.

I have tried to throttle them down to 1.5 but it doesnt make any difference with the capacity.
Also, server 2003 is a 32bit os, but doesnt have the 2tb limitation that XP has.
I currently have a few 3-4 tb dynamic volumes with no problems in 2003.
I will test it with 3 drives in a 64bit OS however. Just in case.
If that fixes it, i will then return to being a very happy person.

I'm having a very similar issue. I have the netcell revolution SR5000 R3-5 controller with 5, 1TB drives hooked up. All the drives show up and I can configure them as raid 3 for a total of ~3.75 TB of space. However Windows Server 2003 RC2 SP2 (32bit) shows ~1.7 TB of unallocated space.
I've converted the disk to GPT but this did not resolve the issue.
Any ideas?

I think the NetCell cards cannot support volumes over 2Tb. Case in point: the 1740 HighPoint Raid Card has this feature listed:
64-bit LBA for RAID arrays greater than 2TB
while its predecessor the 1640 does not.

I have this card working perfectly with 5 x 1.5 TB drives on a PNY SPU5103PPB PCI SATA S-CURE controller. I haven't tried anything but 64 Bit Linux though (Ubuntu 10.04 Server AMD64).
Thanks

What 1.5TB drives do you have running? I've really liked the Netcell cards, they're cheap, simple, and they work, but like all RAID cards they can be picky about what drives they work with and I would hate to drop over $500 for the harddrives only to find out they don't work with the Netcell card.
I've had one 3x1TB RAID running stable with WD Blacks for a couple years, and have been thinking about trying to put together two more RAID arrays. I just ordered several cards from an online dealer, but can't decide which harddrives to get. I've been looking at the 1.5TB WD Blacks, and I already have 5x1.5TB WD Greens I may try to turn into a new RAID after I get another RAID set up and running stable (that way I can empty the drives to wipe them to set up the new array).
I've also thought about expanding my 3x1TB into a 5x1TB, but can't find any solid information on whether or not MBR partitions will work; that is, whether or not I can simply place 2x2TB MBR partitions on the single 4TB array.

OK, I've answered a few of my own questions here. I finally broke down and bought 5x Western Digital 1.5TB Black WD1501FASS drives from ChiefValue.com (a Newegg sister company - they had free shipping and a $15 coupon). My server is dual-booting Windows 7 x64 Pro and Windows XP Pro x86. I booted into WinXP and had no trouble creating a single 6TB RAID-3 array using the App. I then booted into Win7 and formatted the array as a single GPT/NTFS partition of 5.45TB, and booted back into Win7. I then tried to perform long format; about an hour into it the RAID dropped a drive, which Win7 reported as a failing harddrive (at least it's good to know that Win7 correctly monitors the RAID array status). Starting over I repeated, but first I set the jumper on the drives to 1.5GB speed. Unfortunately, I got the same result, a dropped drive after about an hour. At this point I'm wondering if I'm going to get this working... Next I set all the drives to Spread Spectrum/3.0GB speed (couldn't find enough jumpers for both SS&1.5GB). Also, rather than using the WinXP tool I set the RAID-3 array up in the BIOS using the largest block size (256kb I believe; the WinXP utility it was automatically using the 128kb block size). This time I've had success. I've had it running for four days now without any issues, except that the write speeds are atrocious - I was getting from 20-50MB/s write speeds (it got faster as I got closer to the end of the drive). Filling the drive was a lot like trying to fill a bathtub through a straw, but I managed to completely fill the drive after a couple days of continuous copying. Read speeds are better, around 80MB/s, which is close to the maximum you'd expect from a PCI based card; my other RAID array with this card has 3x1TB WDBlacks and I manage to get 50-60MB/s writes and 90MB/s reads. |
