i updated thruogh windows and all is good. However if i needed to downgrade i have no place to backup over 1TB of stuff.

Also i used the Intel RAID console to see of i could change RAID levels and add drives, but the option isnt there for it. Is it bc i already have all the drives on that card in a RAID array? so if i added another 1TB the option would show up so i could add it? I've been searching all over for this answer on google but no luck

Just buy yourself a couple external 1TB hard drives and back your stuff up. It's a wise investment for a semi worse case scenario, Perc Failure, multiple drive failure, virus etc. Just keep them powered off unless your backing up. by looking at the system in your sig, I'm sure you can afford 2 external drives

I'm not sure if you'll be able to jump from Raid 0 to Raid 5 without losing data, i wouldn't want to find out the hard way.

The Perc 6/i can go from 0 to 5. I'm not sure about the 5/i. Under LSI's MSM you use the Reconstruction Wizard to do it.

the same option exists on the 5i in the MSM or the intel raid console. But i dont have any spare drives connected to find out if i can or not

Now that I have my Perc 6/i setup and working what settings should I use for scrubbing, etc?

I've heard something like a "quick" scrub every week and a full scrub every month.

Also, I'm using the LSI management software...

You need to tape pins 5&6 as mentioned in the first post.
post #3488 of 7150
are u shure... it didnt seem to help .. maybe i did it faulty. The problem is that my computer boots every time.. no probs.just raid card is screaming and doesnt seem to be recognized.


Accualy i checked it seems that pins 5 and 6 are not even connected on the board.. i taped anyway and it didnt help.. card still screams like hell.. the processor is heating up tho so something has to be working.
ok i got new info again.. card gets recognized as display controller (in the post boot table). so i guess something with the main board..anyone know the fix ?

another add.. seems liek perc 5/e has diffirent pin output for pcie and as i can see it pins 5&6 are not connected anywhere.. anyone to confirm that.. today i get another computer to test on. if it works should i update the firmware on the card with newest dell one ?

ok another update: i put the card into nforce4 ultra board and it works like a charm.. so my board is the issue.. smbus fix doenst work as i said i even think that pin 5&6 arent even conected on the card. does anyone know why theese cards dont work on some motherboards.. is there a fix for it or i have to replace motherboard ? if i must replace can anyone reccomend a sutable motherborad that supports phenom x3 720be processor...


THX

Hi All, quick question with regards optimal settings (mainly block size...)

I'm about to install Server 2008 R2 on my server (replacing the previous Server 2008 install) and am in the process of pulling all my data off the RAID array onto a spare drive so I can re-create the array with the most optimum settings.

Any suggestions? I'm got the BBU installed and Write back cache enabled.

Config is 4*500GB 7200RPM HDDs in Raid 5. I'll partition it as around 100 gigs for the OS install, and then 1.4TB to house around 700gigs of media, a hundred gigs of documents (ranging from handfulls of kb per file to dozens of megs, but nothing huge) and the rest to house virtual machine images (I have a couple of linux VMs each with around 50gb space and a few other windows VMs for playing around with).

I have a non-raid 1.5TB drive in the machine which I've never needed the capacity of, and am using this to temporarilly copy everything to.

I'm currently using whatever the default block size is (server doesn't have a monitor atached at the moment so can't easilly check). I've seen people suggesting a larger block size (128kb for instance) can yield a performance increase. Is there much merit in this?

Appreciate your thoughts before I'm ready to reinstall stuff in a couple of hours.

Thanks, Pete.

Turns out it was already set to 128k so I left it the same.

I've "upgraded" to the intel firmware posted earlier in the thread though and now unfortunately have the warm restart issues - RAID bios does not run unless starting cold... which is annoying when remotely doing windows updates etc that require a restart. May have to put the older firmware back on.
