even so im considering the next best option:
so if i were to get another perc 5, will my array be dtected by the new card? im running raid 5 btw.

Mike,

If you get another PERC you will be able to get your array back. You should be able to import a foreign configuration, or even re-create the array without Initializing it. I've never saved or imported a configuration, but I have dropped an array of 6x1TB and had to re-make it. As long as you don't initialize it, you will be fine.

Which driver am I supposed to use under XP SP2 (32-bit) for the Perc 5/i card (flashed with the latest LSI firmware)?

I tried the Win2k driver from Dell's site and I get the following error, "The driver selected for this device does not support Windows XP". I tried the driver for Server 2003 (x86) and get the same message. The LSI drivers don't work either with the following message; "The hardware was not installed because the wizard cannot find the necessary software."

I had the card working under XP x64 without any problems.

So... I've just tried setting up my Perc 6/i card and I'm having a problem.

It came with the Dell BIOS 6.1.1.0047 and I was able to enter the card's configuration.

I've now flashed it to LSI 11.0.1.0017 (so I can use their management software) and it flashed fine. However, if I press Ctrl-R to enter the configuration it freezes.

More specifically, it displays this and then freezes:
Quote:
PowerEdge Expandable RAID Controller BIOS
Copyright(c) 2009 LSI Corporation
Press <Ctrl><R> to Run Configuration Utility
HA -0 (Bus 3 Dev 0) PERC 6/i Integrated
FW package: 11.0.1-0017

0 Virtual Drive(s) found on the host adapter.

0 Virtual Drive(s) handled by BIOS.
If I don't try to press Ctrl-R then it will get passed this screen and the OS will boot.

Before flashing the LSI firmware, I did successfully use the Dell firmware to clear the configuration (I was just fooling around).

Can anybody please help me out?

EDIT: Also, there is a flashing green light on the card...

You shouldn't flash any LSI firmware onto a Perc 6/i card because there is no LSI equivalent to it. Flash it back to a Dell card with the most recent Dell firmware. You can use the LSI management software with the Dell firmware (at least under XP x64).

or perhaps "RAID 1.5"... which is a proprietary RAID by HighPoint... RAID 1.5 performs data striping and mirroring simultaneously using only two hard drives. When reading, the data is read from both disks simultaneously and most of the work is done in hardware instead of the driver.

I'm not sure if the Linux PERC drivers support this or not... but I know in windows it is not supported on the PERCs
I'm in the process of running IOmeter to benchmark my RAID-1 array to see how it performs or gives a read boost, but FWIW there is a stripe size setting for a RAID-1 array on the Perc 5/i card.

Really? I could've sworn that I've seen posts that it was OK to do this. The Perc 6/i and LSI 8888ELP both have the same chip.

Oh well. Lesson learned and it works fine now that I've flashed it back to Dell firmware (thankfully!).

Also, the MegaRAID software also seems to be working fine even with the Dell firmware.

Thanks!

Ohh yeaaaa.

Got 1 more TB coming in the mail, hopefully it boosts it some more.
7x1TB WD Black's in RAID5. 64KB stripe, read ahead, write-back, 8MB block test.

Running 6 x 1.5TB in Raid5

128k Block (had 64k previously with 3 disks)

Write back enabled
Read ahead enabled

Still getting 22-25MB/s write speeds

After I initialized, I loaded into windows server 2008 r2.

Fired up diskpart

create primary partition align=1024

formatted ntfs


I tried it without using diskpart, and doing the above procedure. I am still only writing at 22-25MB/s.

Any suggestions would be great

Thanks

Help me! I have a Perc 5e and a Perc 6e and SAS to SATA fan-out cables. Neither card will detect any of my SATA hard drives, I have tried Samsung F1 1Tb drives, Western Dig 1Tb Green, Samsung F2 1.5Tb.....and nothing. I am starting to get depressed to be honest. Am I missing something?? I am using Dell firmware in both cards. I am starting to wonder if the cables are not correct.....they fit the external connectors on the back of the cards.....but could they somehow be wired differently? Or am I just doing something wrong?
