So, I'm not surprised at what you're seeing right now, but I am surprised at how you were able to run SAS/SATA mixed for a year!

actually, I've used them in many dell servers and they come from the dell factory with mixed sas/sata drives and have had no problems.

In my own personal setup, I've run the same mix of 4 sas and 4 sata drives for nearly 3 years without issue.

So I'm kind of at a loss as to why the sudden strange boot issue.

Even after disconnecting all drives, I still can't get into the bios of the perc6i.

Bummer, my perc 5 card just had a FW hang causing system kernel panic. All this happen during its usual patrol check. Now it's rebuilding the current array. There goes my weekends
BTW using FW ver is 7.0.1.0051

hi, been busy and not had time to sort perc 5 card out.

had weekend free managed to get 2 500gb drives online with 512mb memory i upgraded, but every now and again, (maybe every 1 in 3 times) i start my pc the raid card wont be detected by my pc.

I have pins 5 and 6 taped over, i have M2N SLI motherboard with 8600gt graphics card in top primary slot, and perc in secondary sli slot.

any idea why card is not always detected, have just recently done a case swap as well so i can fit more drives inside thumb.gif. just wondering if maybe the tape on pins 5 and 6 are a bit tempremental and causing the error, due to card been removed and reinserted without changing tape,

or maybe will try changing the perc and 8600gt around and try it that way.

Any ideas People.
Thanks.

Hi,
This is a known issue with certain firmware on certain boards.
Search through this thread for Cold Warm Boot, or perhaps the first page of the thread might be useful.
Look in the firmware flash section, it is briefly discussed there.

I know its somewhere in there, I just finish reading the whole thread... my brain hurts!

Card (5i) was shipped friday though!! biggrin.gif Damn, its like christmas eve when I was 5 all over again ...

Hi,

I currently looking for some advice.

I have a Perc 5/i with a RAID 10 array containing 4 Samsung 2TB HD204UIs.This is now full and I want to expand.

I was thinking about buying 6 more drives using 2 to store the data while I recreate 8 drive array.

I then though about using LVM to JBOD 2 4 drive arrays. This way I wouldn't have to rebuild the array so the data wouldn't have to be on 2 drives and vulnerable during the transfer. Also would this not be safer as if I loose an array I can probably still keep half the data. I am not really familiar with LVM and if the ext4 partition on top would store the file location information.

Thanks for you help,
Niall

anyone here have a PERC 5/I setup with RAID-1 mirror set? if so, can you run a few benchmarks (particularly with large sequential writes) with write-back vs write-through?

I'm seeing that performance with write-back is much lower on sequential writes than with write-through. Not only is it lower, but if you graph the performance, it is wavy (goes up, does down, goes back up, goes back down) and averages much lower than with write-through. If someone else has a RAID-1 mirror set on their PERC 5/I, would like it if you can confirm this behavior. Thanks...

Hey guys,

Looking to upgrade my server's storage array from my current 3TB RAID5 (4x Samsung F3 1TB + HighPoint RocketRaid 2300) to a 8-12TB RAID6 (Using a PERC 6/i)

This array will be purely for storage and redundancy of my data (Media, Install files, backups etc), no applications or operating systems will be installed.

What HDD's would you recommend to use, I'm leaning towards being cost effective as performance isn't a major concern as it only streams/transfers over Gigabit LAN or to other internal drives.

I also don't need this solution ASAP, as I'm willing to wait for HDD prices to recede much like the flood waters themselves.


The drives I've been looking at are the Samsung F4EG - HD204UI, but I keep seeing people mentioning TLER and CCTL and these are new concepts to me and I don't fully understand their impact.
I've heard these drives need a firmware patch and that's about all I know so far.


So what drives would you recommend for this setup and what else do I need to know?


Regards,
- R34P3R


TL:DR
Upgrading RAID5 to RAID6, strorage purposes only, best drives to use keeping cost low?

Thanks, deskwizard for your help, much appreciated.

How do i update the firmware, can this be done through LSI megaraid manager, or though bios etc. rolleyes.gif

Also which is better latest dell firmware or LSI????
post #5809 of 7149
rsands16,

The flashing procedure i believe is on the first page of this thread also.
Searching this thread will surely help as well. I'd flash the firmware from a dos floppy/usb drive myself, but I might just be old fashioned....

**EDIT** But it can be done in windows, I'm just not sure it its through the raid manager, but I would be incline to think so. I know its somewhere in the thread, use the search you will find your answer.**END EDIT**

As per the best firmware, I wish I could say...

I know I will stay with the dell myself when I get the card, because "just in case" .

All the knowledge I use to help you comes from this thread, as I don't even have my card yet.

So sorry if I seem to lack certain know how...

Hope this is helpful to you...
