Your bottleneck is the gigabit network, but that's a good velocity and perfectly normal wink.gif

Yup, while the gigabyte has the THEORETICAL ability to hit 1000Mbps....there are bottlenecks. The first of which is the motherboard/ethernet card and the second is your hard drive.

Check this out;

Dude, where's my Bandwidh?

That said, I still hit 57-65Mbps speeds, with sustained transfer speeds in the 40s, so 30 is a BIT low still. However, my network is subnetted with a Netgear GS108T managed switch. Depending on your switch used, and the number of systems on the subnet, network traffic and collisions may be responsible for the slower speeds.

Again.
I know the bottle neck is not in my network, I have moved files at ~100-105mb/sec from computer to computer before (95% nic utilization)

Hey guys, got a problem.
I'm working on adding another drive to my R5, and I accidentally unplugged the power to one of the drives in my original R5 and it became degraded. I didn't realize that I unplugged it until after I used my WDTLER utility and shut down the computer.
Now, I connected the power to it again, and go into the PERC 6i's bios and it says the drive is missing...but it's all hooked up again, SATA and Power.
Is there any way I can remedy this? It's not letting me rebuild my array either. Luckily, it's still operational and all the files are still accessible when I'm in Windows.
Why would it say the drive is missing when it's really there? Do I have to format the drive in Windows and reconnect it to the card?

As you can tell, I'm at a loss...please help!

Thanks in advance!


EDIT: Here's what fixed it (easily)
When the system was booting, I got the usual PERC load screen, but also got this message:

I was hitting CTRL-R to go into the BIOS to try to figure, but that didn't work.
So, when I rebooted the machine, I hit "F" this time and it loaded into Windows. I checked the array with MegaRAID and noticed it was rebuilding.
So, the fix was to press F when I got that screen.

Hope that helps anyone in the future...even though it's kind of an easy one.


old post but this just helped me. I turned off my computer on accident. (no bbu or ups.working on it.) go the same screen as you. I entered the perc 5i's bios. And then got out hitting the ctrl alt delete and the array showed up perfectly. still learning a lot with this card

Hey guys, I'm having some trouble with my PERC 5/i and Ubuntu x64. I'm trying to get Megaraid Storage Manager installed, but having no luck. I've googled and searched through this thread to try and find anything, but I'm coming up blank.

Right now, megaCLI is installed and working properly. I have MSM 9 beta for linux downloaded and I've used alien to convert the rpm to a debian package. Everytime I try to install this, it starts up, gives me some error about how there are "no such files and directories" during the post-install, and then nothing runs.

I've been trying to use this to clear my hurdles, but many of these directories don't exist on my system, which makes me think the installer isn't working right at all.

Any help would be greatly appreciated.

If you get it figured out please post how. I was going to do the same thing and downloaded the same instructions you have but haven't tried it yet. i was thinking I would end up using a VM or WINE (if it worked).

Well I tried installed the latest LSI bios to my card.... I now get Error 10 (in device manager) and the card is no longer detected in windows.

Looking at these on eBay, some are very cheap (1950s in particular). Are those bad, or has the market bottomed out? What are the model numbers for this controller?

You need to be extremely careful !!

Some of the sellers - doesn't know what they are selling.

PERC 5/i, PERC 5/e, PERC 6/e - have memory stick clearly visible - so this is easy smile.gif

PERC 6/i have memory on board but there is chip with radiator on the right side of the PCI-E slot - SAS 6/i doesn't have radiator and main chip is located on the left side of the PCI-E slot.

So:

PERC 5/i:

PERC 5/e:

SAS 5/i:

PERC 6/i:
