RSalamon, what cable did you get, can you link the site? I'm not seeing my drives with the cable i have so I need to get another one but want to make sure I get one that works.

Thanks.

So, I think my BBU is jacked on mine, now. I see several events in the logs about the BBU, and when I reboot and have a monitor plugged in, I see an error stating that the battery isn't present or that it doesn't have sufficient charge.
Cool thing, I sent the eBay seller an e-mail and he is going to mail me a new BBU to see if that helps! I got the PERC + BBU/cable for $125 shipped, which I thought was awesome, and post-sell support like that has me happy.

Here are the cables I ordered:
http://www.computercablesource.com/sas-cable-05-meter-internal-sas-32-multilane-host-to-4-sata-target-1448.html. Price is right, and I got overnight shipping on them even though I ordered at 3:45pm PST. I've ordered from that store a fair amount and they've always treated me proper.

I feel like I'm posting a lot in this thread frown.gif. Sorry.
Does anyone have a guide on doing capacity expansion? I just bought two more drives to throw at my array. I may want to change it to RAID6 for the redundancy, unless there's a serious performance hit from doing so. Either way, I want to add both of these drives to my current array... I took a quick peak inside MSM but nothing jumped out at me.

Finally installed my Perc 6/i after having it lay around for 4+ months, but I have nfi what i'm doing frown.gif

Should I full format the drives before doing anything? - they've all had data, i've simply deleted the partition tables

Card has Dell FW Package 6.2.0-0013 (1.22.02-0612)
No extra cooling - does the 6i need as much extra as the 5i? (I got extra heatsinks, but no mounting solution frown.gif )

Win7 auto installed drivers 6/2/09, 4.5.0.64 - the best option?
I installed LSI MSM 8.16.0100 - compatible with the Dell FW? worth having/using over just the Bios setup?

I want a R6 setup with all my 6 2tbs, what stripe size? and other config (read ahead, cached IO, disk cache policy)?
If they are empty drives should it require a full Initialisation? how long should that take?

I thought i'd just try a 'simple' setup, and it decided to start a background initialisation - which eventually suggest a 30+hr estimated time :\

frown.giffrown.gif any help

EDIT: also, is there a staggered spinup option anywhere?

Heh, I wish I could help you with all of those. I suggest googling the Stripe Size question - it mostly centers around what you plan on actually doing with your storage. I went with 256KB myself.
I'm also using the same MSM version as you, and it is working wonderfully for me. I played around in the BIOS before that, and either/or seems like it'd work, but I prefer the MSM interface right now. One thing I really like about MSM, is that I can sit at my desktop and work on the array, rather than having to RDP or something to the NAS.
The other config settings you can play with to tweak performance later. Do you have a BBU?
I don't believe you need to format the drives at all. Just present them as raw disks to the controller, then let it build the array. Once that's built, you'll have to carve up the array how you want to (I'm running Server 2008R2, so I just used it's built in disk management to carve up the array).

I don't know about the auto-installed drivers. I actually went to Dell and downloaded the latest ones I could find from there and used them.

For the cooling... I just bought a low profile 40mm fan and screwed it onto the dell heatsink. The screws fit between the fins just about perfectly, though I could only get three on. However, with all three in, the fan was secure.

It would be best to do a full initialization, from what I read, so it doesn't have to do any/as much parity calculations when it's actually using the array. It'll take longer upfront, but save you time later.

One thing I did was a lot of googling. And the MSM has a decent manual built in as well that you can reference.

Some of the above may be incorrect / not exactly accurate, but it's what I've found online, so it must be true, right? biggrin.gif It's working for me, though I don't think I'm getting peak performance out of my setup...

This can't be good. The OS drive in my NAS just bit the dust. PERC'd BIOS still shows the virtual disk... anyone have any pointers on how to re-access the data once I get a new OS loaded on a new drive?

Edit:
Nevermind. That was the easiest thing ever. Just plugged in the new drive, PXE booted, installed a new OS, re-created the shares and all is well.

Some update on compatibility:

I can confirm that the Dell Perc 6/i runs great on an Intel DP55WG in one of its x8 PCIe ports without any modification just great. I've got RAM in all of the available banks and there are no problems.

Furthermore I can confirm that the Dell Perc 6i works also great on an Intel DH55DC (in the PEG PCI x16 slot!) without any modification. Either I was very lucky, or the issues regarding compatibility are away wink.gif.

Both configuration are running with 8x 2TB F4EG hard drives. I now have to figure out the best configuration (strip size, block size of file system), so this will take some time wink.gif.

I'm pretty sure all the data\partitions will be nuked once you create an array on the perc 6/i

There is a new firmware for your PERC HERE. The stock heatsink should be fine, make sure there is a fan mounted on it running at either full speed or 7v. On my Perc 5/i i have a little 40mm fan running at full speed in summer and 7v in winter and the heatsink only gets warm.

Stripe size will depend on the type of data you plan to keep on the array, i think most people use 64k or 128k. read ahead should be adaptive. cached IO is actually slower than direct IO. Disk cache should be enabled.

Hi,

I just ordered a Perc 6/i card. Until now i have used software raid 5 in linux.
Today i got 5x1,5TB Samsung F2 in that raid 5 setup. But i want to migrate to raid 6 instead, so i bought the Perc 6 card.

Now to my questions:
I'm looking for 2TB 5400rpm SATA disks for the moment. I don't really care about speed, so i'm going to settle for the best/cheapest HDDs.

The once that i found so far is:
Samsung F4 2TB
WD Caviar Green 2TB
Seagate Barracuda LP 2TB

Has anybody got any experience with those drives?

I've also read something about the "green" drives could cause trouble if they spin down? Anyone got any input on that?


Also, what is the recommended stipe-size for say 8x2tb RAID 6 array?
I'm going to start out with 4x2tb drives in raid 6, does that affect the recommended stripe-size(guess it's not possible to change the stripe size once there is data present in the partition)?


Oh and I more thing, can an existing raid array be moved from a PERC 5/i controller, and imported to a PERC 6/i?


Grateful for all the input i can get! smile.gif
