PERC 5/i RAID Card: Tips and Benchmarks - Page 380

post #3791 of 7269
Turns out the device is disconnecting itself when I get these huge lock ups. In Dev Mgr it is viewable but when I try to view it, it ends up disconnecting and giving me this error:

Quote:
Currently, this hardware device is not connected to the computer. (Code 45)
Recommended resolution

This error occurs if a device that was previously connected to the computer is no longer connected. To resolve this problem, reconnect this hardware device to the computer.

No resolution is necessary. This error code is only used to indicate the disconnected status of the device and does not require you to resolve it. The error code resolves automatically when you connect the associated device to the computer

I wonder if there is any point in trying the perc in the main pci-e x16 slot ( I have 3 x16 slots, which are pci-e 2.0 x16 x8 x8 or x16 x16 x1 configurable).

The best choice right now for a storage array is probably the 5-platter Hitachi 2TB disks. Everything I have read points to them being most reliable for RAID use as they seem not to suffer from TLER-related problems, although they run hotter, use more power and are louder than the competition. They are quite cheap though.

Hope this helps a little.
Well, i was really pounding your post and i think have planned a final drives set scheme :

As i've actually a restricted budget, i was thinking doing it :

Instead of starting w/ a lot of smaller drives, i'll "only" buy 2 * Hitachi 2To and begin w/ a simple RAID1.

Later, i plan to buy 2 more same drives.

Here's the question : i suppose i can't extend RAID1 to RAID6 directly ?

If not, it isn't a real problem : flush data / format / create new RAID6

Well, just wanted to know if my plan seemed "clever"...

In fact, finally i really like the "larger-drives" way because i'll manage to keep my RAID array "homogeneous" as i'll easily find, later, the same Hitachi 2To drives (and at a lower price)...

Unless this is a bad idea to buy drives at different times (different fw, etc...)... Even i think that all RAID arrays evolve and that newer drives will so appear in the array...

One last thing : do you confirm that you was talking about the deskstar series (and not enterprise one) : HDS722020ALA330 ?

This article quite tempted me to buy Seagate 1.5To drives : http://www.smallnetbuilder.com/nas/n...earned?start=1

Thank you.

I decided to go entirely simple, no WB, no ARA, no cached i/o, raid 1 with 2 drives. This time I was able to start a transfer. It started off fast but eventually tailed down to a crawl and froze up. The controller proceeded to go offline after freezing up for about 5 minutes. This has got to be a controller issue at this point right? Should I just return this thing? I'm really just sick of messing with it. I've spent over 18 hours in the past two days. I'd love for the damned thing to just work but alas... There really is no reason the controller should just GO OFFLINE, unless its bad, right?

Does anyone think it could be going offline because of incompatibilities? I would think once it boots up, created a VD, etc, that those activities should show that the card itself is communicating with the motherboard ok and any failure with the actual transfers and what not is a card failure.


Is there any reason for me to try another 6/i or a 5/i? Should I just go another route for the ~$200 raid 5 controller needs I have? Someone?

Try the card in the other slot. A lot of boards have problems with different PCIe/gpu/RAID combinations. Yours might be one of them.

Also if you can buy a decent 8-port, hardware RAID5-capable controller for $200 then please share. There is nothing that comes close the the PERCs for the money - hence their popularity...

Regarding the different board revisions - IIRC the difference between the v1 and the v2 board is the onboard SAS. This might be more significan than you realise - by removing the extra disk controller, Asus might have reduced the amount of Option ROM onboard - reducing costs, but also meaning that the v1 might have the capability to run 2 simultaneous controllers (ie designed to run the SAS controller and the ICH10R, but capable of running the PERC and the ICH10R instead), whereas the v2 only has the Option ROM to initialise 1 controller at once. Whether or not you have NICs set up to PXE etc will also affect the boards ability to run more than 1 RAID controller at once.

You should be able to directly from a 2-disk RAID1 to a 3-disk RAID5 or 4-disk RAID6 (or more disks - but they are the minimum numbers supported for each RAID level. Always thought it was a shame you can't do a 3-disk RAID6 though...).

I will ask around & try and nail down the model of Hitachi drives for you - I'm not using them, so don't know off the top of my head...

Very good information there. I hadn't really thought about there being limited rom space for booting up multiple controllers. In this day and age, I find that to be absurd if true. I don't see how they could skimp on rom space on a ~$300 motherboard. Hence why I like to go with DFI, not that I can show they don't have the same issues, I just like their brand. Asus has become a bloated machine....

Anyway, I have 3 slots, I tried the card in 2 of the 3. I hadn't tried moving the video card out of it's main spot. I also haven't tried to do AHCI or IDE mode on my SSD since it has my OS and I don't want to re-install right now. ACHI/IDE cause it to crash where as RAID works. Shouldn't make a difference, but I seem to recall doing some research about the issue a while back and it's some STUPID AHCI/RAID flag you have to manually set in Windows 7 ( and vista ). Yeah, I'm sure of it actually, it's a reg key issue.

Also, if it is of any significance, I have run a SAS 6/iR in this board and it worked with raid 0 and raid 1, no issues. I think that kind of points to the PERC 6/i being a bad controller again, but I don't have all the variables to the equation...you rarely do.

edit: I read up on option roms, makes more sense now. Would disabling one of my two gigabit ethernet controllers in bios do any good? I don't use PXE.

Do you use the PERC for boot at all? If not disable it's BIOS - it should only be needed to be initialised by the BIOS if you need to boot from the card. You can still run a storage array, but you need to manage it from MSM in Windows.

For testing purposes why not disable both NICs entirely? Although this probably won't affect your issues. I think it is likely to be a cooling issue, a PCIe issue, or you have a faulty card. If it will not work in any slot, you have high airflow over the card (point a high-speed fan at it for testing) and you have managed to successfully update the firmware to the latest Dell it would seem your card is the issue.
post #3798 of 7269
I don't use the perc for boot so I an disable the bios. Would doing so effect the windows lock ups the card goes through after a VD is created? Are there ways to monitor by software the temps of the card? What are its maxes and does it auto shutdown if those temps are reached?I have the latest dell firmware on it and the sas 6/iR worked fine. Think I may wait for another perc from borito.
post #3799 of 7269
I don't know of any way to read the PERC temps - but would expect it to lock up if it overheats. If you don't have good airflow over it this could well be what is happening.

I doubt it has sensor....
