You should put the 4 36GB SAS drives in Raid 0 and install the OS and programs on it. Then pickup at least 1 more 250GB drives or better 2 and put them in Raid 5. You will get great performance on your OS with the 4 SAS drives and data redunancy and performance with the Raid 5.

i would get more performance on the raid5 than raid1 sure, but i don't really need it for "backup storage"

i would, but i intend to give my third 250GB drive to my grandmother hehe. im making a computer for her out of spare parts. i do not wish to use an old IDE 80GB drive in her build.

turns out, a 35watt celeron 430 puts out more horsepower than a 3000+ sempron. she demo'd my "home server" for a few days as a desktop. she loved it!

i guess its not just the youth who seek a better pc

but yeah, raid0 on the sas is most likely the plan. that plus backups of my source files and such every few hours, and of the OS every night should work fine. if anything raid0 on the SAS for benchies is the least i can do for this thread!

I didn't have any problems flashing back to the Dell firmware from the LSI firmware. The Dell flashing utility for Windows warns that I'm flashing to an 'older' version, but other than that it didn't give me a problem. Just note it'll flash all the Dell Perc 5/i cards in your system; it won't just let you choose one.

I went from LSI firmware 7.0.1.0051 to Dell firmware 5.2.2.0074. I'm going to try flashing back to the LSI firmware though since I think the Dell version is giving me compatibility problems on my mobo after flashing (Asus M3A79-T deluxe). The posts on data corruption worries me; I'll just have to try testing that out when I get to it.

EDIT: That did the trick. Apparently this mobo doesn't like Dell firmware (or at least the particular firmware I tried). I think this problem may be applicable to the Asus M4A79 Deluxe too since it looks like it's essentially the same motherboard.

The card will keep your configuration, even if you change motherboards. However I would HIGHLY suggest to format your computer when you change your motherboard.

i fully agree. however, if say my board dies, i cant get another identical board. so i get a different board. what happens to my data? if it cant keep my array.. im SOL.. however if i can read my array to do backups, i can backup my data. reformat for the new board, and restore my data and be all jolly go happy

after realizing how much time it took me to create that measly 16MB aprox of data, i have realized that i should "play chess" with data backup and data safety.. i do not wish to lose data again hehe


to SockMan!:

what issues were you having with the dell firmware?

also, does anyone know if the LSI firmware and drivers offer new features or bug fixes? or if its possible to flash to LSI with w7, boot up install LSI drivers, reboot uninstall dell? (or another pattern?)

Simply put, the cards weren't being detected and initialized at boot up. It also caused a ~15 second delay between hard boot and POST. I flashed back and both my cards work fine.


You can move the disks to a replacement card PERC 5/i without any issues. I tested this out with my two cards; I simply moved the cables over from one card to the other and my RAID array moves with it.

This cooler works great on my 6/I, has a very strong addesive pre applied, you just peel the sticker and put it on, so make sure you get it right first time.

Only about £8 in UK

Also has anyone seen this?

Controller ID: 0 Battery/charger problems detected; SOH Bad

When I woke up this morning it said this message in a pop up several times (even though no BBU is connected) my BBU arrived this morning I connected it all but it stated the error about giving it 30 minutes to see if the message went away, no BBU showed up in the MegaRAID software. Gave it about 2 hours and nothing appeared still so i took the battery out and messaged the ebuy member about it. Just now its come up again, could there be something up with the actual controller?

Thats a simple one. You dont need to reformat any data partitions just your OS partition. You get a new board plug a hdd into the Motherboard load an OS, dont worry about activating it. Plug you PERC card in install drivers. I hope your OS is on a different partition then your data. Copy anything over from the OS to the Data partition. Then just reload your OS on the PERC and your good to go. I was modding my main PC and I had a backup pc and I just move the perc and the Raid5 drives over to the backup pc. I left the 3 sas drives with the OS not plugged in. When I finished modding the PC, I plugged the 3 SAS drives in, imported the foreign configuration and I was good to go.
