PERC 5/i RAID Card: Tips and Benchmarks - Page 141

post #1401 of 7257
yeah, crossover cables are the wrong ones if you would go read the entire thread now, you would laugh at how many others made the same mistake

good news Gooda.. the SFF-8484 to 4x SATA are cheap..

the SFF-8484 to SFF-8482 x 4 (aka splits to 4 SAS cables) are expensive and i might need two of them depending on how my shipment from ebay goes today

I already had the right cables for one SAS connector...I just misread (or rather...just completely missed) the crossover part of the listing. I assumed "Works with PERC" meant that he had used it before. My fault, oh well.

Potentially a simple question - has anyone reflashed back to the DELL firmware?

I'm debating on doing so, since with the LSI firmware I can't get it to boot off of the RAID card, works fine as long as it's not talking to the BIOS as being bootable (windows XP starts to load, and then goes to BSOD or simply runs away).

I'm running version 56 of the LSI drivers (61 didn't allow soft boot) and version 2.20.0.32 of the LSI XP drivers.

also if I enable BIOS handling in the POST configuration utility, something flashes up quickly about not being able to do something in regards to the NVRAM (it's so fast I can never see the text) - but it appears right before the POST message of checking NVRAM appears on my P5E3 M/b.

so I'm thinking all this is related to the LSI firmware.

Running secondary drives is no problem - it works wonderfully and about 20% faster without even RAID enabled on a single disk set up as a virtual disk by itself as compared to ICH9R. my compile times went from 460 seconds in total down to 350 seconds just by moving my development drive onto the PERC controller. But I'd love to be able to move my striped boot drives onto the PERC

Did you re-install XP AFTER flashing the firmware to the LSI version?

i wish to take a moment to thank everyones contributions in this thread, and to confirm that i have a perc 5/i working on a asus p5b deluxe motherboard with the tape trick.

little worried about the tape.. my electrical tape isn't normal electrical tape.. its like a "cloth type thing" works well for wires that you can wrap it up on.. but it wouldn't work for the card (not sticky enough..) sooo... im using duct tape atm

any voltage going through those two pins? or anything serious i should worry about with the duct tape??

currently my raid5 is initiating.. got like 90 minutes to go. il bench then.

also waiting to get a SFF-8484 to SFF-8482 cable to install my four new SAS drives. maxtor 15K 36GB drives i will be creating a raid0 with those probably.

i don't understand what you are all talking about when you say your raid 5 is initializing? i set up raid 5 and it took like a minute to initialize... is something not right?

it does some sort of "background" version while your booted up into the operating system..

attached an image to show.

The standard initialization takes a few hours....you must have selected quick initialization.

maybe that's only with the LSI firmware? i'm using the dell firmware that the card came with.

im using dell firmware too. perhaps you just didn't notice it? or you didnt install the megaraid manager? i couldn't find the mr manager branded by dell, unsure if one exists.. but the LSI seems to work fine?

no current intentions to flash the firmware. i just got this baby! and im seriously scared of flashing firmwares/bios

that, and the fact i cannot seem to flash back to dell if i flash to LSI.. the risk isn't worth an extra few % of performance IMO.

my main objective is to keep "good speed" with redundancy, as well as features such as "reconstruct" to add more drives, as well as not having to rely on reinstalling the OS if i switch boards (hoping on this one lol) nearly impossible to switch boards without reformatting with onboard raid..

once i get my SAS cable. i predict the following setup:

4x sas 15k 36GB in either raid0 or raid10
two 250GB sataII seagates in raid1
"very often" backups from the SAS to the 250GB array.

i am beginning to work more and more with data i do not wish to lose.. i am very upset as it is moving to this card.. turns out i forgot to backup around 15-20MB of data i have coded over the past 3-4 months..

this data was revision backups of php/html files.. a sum totalling over 160,000 lines of code.. fortunately the "current revision" code is active on the server. or id be SOL for sure!

i plan to try and make sure that data loss of such does not happen ever again.
