ICH10R Raid5 size limit?

I'm trying to replace a 3ware 9550sx-12 based system with a Gigabyte EX58UD5 mobo which has the ICH10R Intel chipset. The problem is, when I try to configure Raid5 with the six 1.5 TB seagate sata drives, the bios Raid setup utility tells me the max I can do in raid5 is 432 GB... ? Any ideas how I build a raid5 with 9TB raw total? Gigabyte didn't even bother to respond to my support request.

Suggestions?

Get a third party RAID card, it would also make the array portable if the MoBo died.

432GB is ridiculous, three 250GB drives would bust that limit and most enthusiasts would call a 250GB drive "obsolete".

I ended up with a Adaptec 3805. I'm thoroughly disappointed.

Hey tc0nn...
I had the same problem..with a ASUS p5q-e motherboard...6 x 1.5 tb seagate.. 432gb for a 6 disk raid5..when I create the partition in bios...

instead I created the Raid 5 array directly in windows under intel matrix storage application, and I have the whole 6983gb space.

I hope this help some of you folks ;)

I returned the Adaptec and ended up with a 3ware 9650se-12 for about half the cost of the 8 port adaptec. No problems since...

Tc0nn, please answer this question: are you using the 3ware card on the Gigabyte board?

I ask this because Gigabyte boards have been known to be incompatible with PCI-Express x4/8/16 Raid controllers. I even tried it with my 3ware 9650 8port less than 2 yrs ago and it didn't work.

Also, I would APPRECIATE any screen shots of performance numbers of your Raid 5 array.

Did you know that the Highpoint 4320 is on sale at newegg for $390? From what I have read, it is much faster than my 3ware 9650.

I forgot to ask if you knew about LSI buying 3ware from AMCC?

No, but that's probably a good thing. Seems like LSI always had better quality but 3ware/amcc had the most economical controllers. When I worked at The Planet, we we're using both, just depended on how expensive the server was and how many ports/drives you needed. As far as performance, I don't but I'll work on getting some numbers. I'm using the 3ware 9650se-12 on the Gigabyte EX58UD5, i7 920 proc, running 6GB ram, 6 1.5TB Seagates, Fedora Core 10 with a cheap 512MB video card. This server stores my DVD iso files and holds backup images of other servers so performance was less of a priority that total disk space. I'll grab my receipts but I think I basically built a 7TB (raid 5) box for about $2k. What util do you guys use to grab numbers in Linux?

For Linux, I can't remember what I have seen people use but it should be built into Linux itself. Some sort of commands for read and write which produces a log.

Do you know about Storagereview.com which also has a forum?

I like your setup. I, too, like Seagates in addition to 3ware.

What do you mean by LSI having better quality than 3ware?

I ask because I bought a LSI SAS/SATA 8 port controller about 1.5yrs ago but it didn't work. Its too bad because newegg had really screwed up the price and was selling a $600 card for $275.

Should I worry about my 3ware card? Its only a bit over 2 yrs old and I don't have a spare one.

One more question: why don't you compress your DVD images? It would save you a lot of space. Or are you planning on adding Blu Ray to it also?

3ware seemed green at the time. They are much better since AMCC took over.

I don't compress the ISOs because I don't want additional load on the CPU. Network is cheap, disk is cheap, cpu is the limiting resource at this point. Regardless, most of the software only pulls the data in chunks so its not like it has to download the whole 4/8GB file before it begins to play.

Stay away from Seagate drives as for controllers go with Adaptec

Seagate 7200.12 are fine - stay away from the .11s though.

I cant for the life of me understand why somebody would send back an Adaptec 3805 and replace it with a 3Ware card... the Adaptec Storage Manager is so much easier to understand and manage then the 3Ware management tool in bios the Adaptec Card out performs the 3ware by leaps and bounds.. the advantage that 3Ware has is the raid building times and rebuilding times. but that was not mentioned in this threads... as to the drives I would NEVER NEVER NEVER use Seagate drives again not after the way I took it in the shorts and the response from Seagate being that it was just "internet fireworks" then they came out with 2 firmware changes in 3 weeks and did not post them but had to down load them from the support people and only after you begged for it. crumb bumbs.

The NAS at my company has a 3Ware 8506-12 SATA controller. There are 10-120GB Seagate SATA drives configured in one Raid-5 volume. This was probably a decent setup for a small business when configured 7 years ago. This server has been extremely reliable through the growth of our company and is relied on by 80 employees in 2003 to over 220 employees today.

This was a great solution for me. I use this system as a backup server and just upgraded it to 3x2TB drives. Trying to create the raid 5 in the BIOS only allows 2TB of space to be used. Downloading and installing the matrix storage mananager allowed me to use the 4TB I was expecting.
