PERC 5/i RAID Card: Tips and Benchmarks - Page 498

post #4971 of 7174
I'm using 4x1TB WD green drives on a PERC 6/i for about a year and a half and have no problems at all
post #4972 of 7174
The perk 5 card is found so cheap due to its not ideal for servers. Dell used them in the 1U's and they admit they are the cause of the issues plagued in our servers. I certainly wouldnt want one of the Perk 5's just from my experience with them.

Great news, thanks. Anyone else have experience with greens?

Well, I hope you are wrong, I just ordered one. However this page is almost 500 pages long and the consensus seems to be that they are the best card to get without breaking the bank.

Where do Dell admit this? I have used PERCs for years, never had any real issues with them. They have a few limitations, but because of their low price they are head & shoulders above any other option.

i would mostly agree with you... the PERC5 are pretty solid, but they do have some problems that Dell has had to deal with like not being able to reliably clear the configs off a drive without it clearing it off the controller too, etc. Most of the "quirks" were addressed in the PERC6. either way, the issues with the PERC5 doesn't render it useless in my mind and I don't believe Dell have ever made such a statement to that effect.

I had MegaCli working great in Arch and I can't seem to get it working again after reinstalling on my home server. I extracted the binaries using rpm-extract, then checked permissions and placed them in:
Code:
/opt/MegaRAID/MegaCli
I had a script in place that did this:
Code:
sudo /opt/MegaRAID/MegaCli/MegaCli64 -AdpAllInfo -aAll |less
now it returns nothing. The program itselfseems to be working, since I get output on:
Code:
 /opt/MegaRAID/MegaCli/MegaCli64 -h
I still haven't rebooted since extracting the rpm...but I don't see why that should matter. I only reboot on kernel updates normally, and I never had problems with it before. Maybe I'm missing some sort of dependency?

Anyone have any insight? Someone else said they were running it in Arch IIRC....


Also I've been having a HELLUVA time with my RAID5 array failing. These WD Caviar drives (with TLER fix) just aren't cut out for RAID. They array once dropped simply from running an NFS benchmark (bonnie++). I tried running 6*500GB+ 1 500GB hotspare and even when it failed the hotspare wouldn't always rebuild, leaving the array completely failed.

Could the TLER fix actually be causing any problems? I ran these drivers on the PERC for quite some time without a huge amount of problems. It would fail sometimes, but I could always import the foreign config and be good to go.

Another thing that is getting REALLY old....I can't seem to get the controller to clear a foreign config. It has come to the point where I have to pull the drive, install it on a SATA port, format it in ext4 or something, then put it back. This is insane. Maybe it's the newer firmware, but I'm quickly losing faith in these cards. I'm just glad I have all of my data backed up in triplicate.

EDIT:
I'm beginning to wonder if it's this Icydock external enclosure or the SAS to 4 eSATA cable that is causing the problems. The drives I have inside my case never cause a degraded or failed state.

Actually I've been a bit backed up with school, so I haven't been able to test just yet. I plan on giving it a shot tomorrow, provided I can get this man RAID 5 array to behave. It just keeps failing over and over.....

Tomorrow I'm going to test all 6 of the drives inside the case instead of having 4 in the Icydock enclosure.
