RAID suggestions?
Looking to build a small-mid sized storage server and I'm looking for a
couple suggestions... Going to be using eight 250gig SATA drives in a RAID 5 (?) configuration and was wondering what I should consider for a controller. Are there any mainboards that would support this configuration? Add on controller cards? We don't want to lose data on these drives (there will be a separate drive for the C:/ System files) as well as get the best performance possible. The reason I'm considering onboard is that performance could be better if we can avoid using the PCI bus for the controller. Thx! |

Take a look here for cards and reviews;
http://www.3ware.com/products/serial_ata.asp http://www.promise.com/ http://www.tomshardware.com/storage/20040625/ I've haven't heard of a mobo supporting Raid5, just 0 and/or 1. 2 cards/arrays with 4 drives each would give you 1500GB (750GB each array) of storage.

Unless you're using GbE network connections to the clients, the bottleneck (on anything but a very busy fileserver) will be the network, not the drives. Without GbE you don't need high performance drives/configurations. Onboard controllers which use their own chip, not a southbridge integral feature, ARE on the PCI bus. There is no gain to having such an integral chip rather than it sitting on a PCI card. It is exactly the same situation if it were placed in same PCI slot such that it had same IRQ. |

It is exactly the same situation if it were placed in same PCI slot such that it had same IRQ. My Asus P4C800E has the Intel Raid controller (as well as a Promise controller) and the Intel part doesn't utilize the PCI bus. I was hoping another higher end board might have taken this farther. What I'm looking at now is: http://www.raidcore.net/RC4000DataSheet_2.pdf In this Lian Li chassis.... http://www.lian-li.com/product.php?a...wPD&prdid=1210 ....assuming I can find suppliers for them. |

This will most likely be an Athlon64 system (unless you can convince me otherwise) : ) |

Intel does have southbridge raid, but never RAID5 AFAIK. It would seem you are forced to use a PCI bus based solution, as with what you linked. It is PCI-X though, you didn't distinguish what mainboard you're looking to use, nor the budget. I deal primarily with PCs also, am certainly not the best person to advise on RAID5. |
