PERC 5/i RAID Card: Tips and Benchmarks - Page 48

post #471 of 7149
I think I do a consistency check once a week, but at a 30% rate. I don't know if that's too much, but at 30% I don't really notice it.

I would add all the drives at once, then you won't have to wait each step. (-:

I use the LSi BIOS/Driver and have the storage manager installed, and after I setup my raid I pulled a drive (just so I know what would happen), a message box appeared instantly telling me that ARRAY 0 was degraded. I believe it even said what drive number failed. Anyways, a couple minutes later I slid the drive back in, opened up the storage manager, and rebuilt just fine. I never even had to reboot.

It did lag a bit for a few hours due to a 75% rebuild rate.

I hope that info helps.

Well I finished benching my machine with 3 SAS drives and just realized that my motherboard is only running at at 1X, I guess I have to upgrade to a X48 chipset.

I guess i am looking for a second opinion on upgrading my raid array.
Thanks to xboxor for the first opinion.
I currently have 4 drives and will be adding 4 more.
should i just do the bump straight to 8 or should i do 1 at a time? When adding a drive am a at a higher risk of failure? or while adding that disk am i still able to loss a drive without the entire raid failing?

I would test each drive individually using a diagnostic program, then just add all of them at the same time


On a side note: my new mobo arrives today - hopefully Ill have RAID 0 benches against NVIDIA RAID by tomorrow

I do believe that while expanding an array you are exposed to the possibility of data loss if a drive fails. I'm not 100% on that though, and without knowing for sure, I feel safer telling you that you're exposed to risk, rather then saying that you'd be fine.

Again, I would add all 4 at once. I think it would take less time then expanding 4 to 5, 5 to 6, 6 to 7, and finally 7 to 8 drives. That's a lot of expanding.

If it were me I would do it before I goto bed, and I would do that in the Perc BIOS, rather then through the software, unless you have you OS on another drive. I like doing expansions when the array is offline. It's so much faster!

Hope this helps.

I'd test them all first, back up the data already there, then add them all at once. Then it doesn't matter if they fail

I've got the Perc6/i Fired up & working on the Gigabyte EP45-DS3P.

Had to cover pins 5&6

Would not work in x4 mode.

Works with GA-G31M-S2L with and without the pin-mod.

How do I test what speed is the bus running at?

Yeah how DO you test what the bus speed is?

Hehe, but i am expanding cause i am out of space
I will try to backup the mission critical data, but i will have atleast over a TB that i don't have room for.
