PERC 5/i RAID Card: Tips and Benchmarks - Page 441

post #4401 of 7150
I'll crack open the battery pack tonight and snap some pictures and trace out the leads to figure out exactly what needs to be done.
post #4402 of 7150
So I am kinda interested in getting rid of my Physx card, which would give me money (and a 4x slot) to pop in a raid card and get down to business. My question is how difficult is installing drivers and getting this stuff to work?

Now in the disk group tree you'll see something called "Space Allocation" *Free Space * 300GB (real size will be in MB of course). So you select it, hit F2 -you got only one option - add new VD. You hit enter and next screen is your Raid Level - Raid 0 (unselectable), your drives - 4 HDDs (unselectable), VD size - unselectable, advanced settings -selectable (stripe size,read policy,write policy, Force WB and Initialize), than you have OK and cancel. Wasn't hard was it? What ppl are trying to convince me in is that you can distribute *Free Space* for any raid level you like - which is what i called BS (sorry there's no other way to call it in english). You can not period. It's not like Intel matrix raid where you CAN DO it. Same thing will happen if you try to create raids from within OS using sas manager, I tried both dell manager and lsi mega manager. I have dell firmware, I haven't seen anyone running LSI firmware on Perc 6i card in this thread.
So please let's add that valuable informatiion to the sticky in the first post that it is not as flexible as intel matrix raid in terms of setting it up for home usage (small fast raid 0 array for OS and games etc and large RAID 10 array for data storage).
LOL, I created the thread.

Sorry for the confusion but it wasn't clear what you wanted to accomplish.
Once again...

If you have an x8 (or higher) slot, or an open ended PCIe slot, it is very easy to accomplish, but note that the PERCs will not fit in a standard x4 slot.

Getting a PERC up and running is pretty simple - put it in and switch on. If it appears in Windows, then you're away - install the latest drivers and the management software and that's it. If not, take out the card, cover the pins shown in the OP and try again. That's about it.

(obviously there might be a little more to it than that as this 450 page thread shows, but that's it in a nutshell...)

I have a full length PCIe slot (gts 250 is in it now) but it runs at 4x 2.0

You should be fine then.

A 4x slot offers plenty of bandwidth for this card.

You may have to cover pins 5&6 to get the card to work properly with your motherboard.

What operating system are you planning on running? Will the array be your boot disc or a storage array?

Not sure yet, this is purely speculative, but probably a storage array. I have a few TB's I need on something with a little bit of redundancy. Figure 5-1.5tb HDD's would be good. I run win 7 99% of the time, unless I feel like dicking around with linux I keep arch installed sometimes.

Alright, You'll be fine.

Plug your drives into the controller. Boot in to windows. Windows 7 will install a native driver. YOu can update it through Windows updates or on the Dell/LSI page.

Once the driver is updated you can installed the Storage manager. Use this to configure the array. You could configure the array in the Raid Bios, but a GUI is easier

Alright, I got around to opening up the Perc 5 BBU.

Here is the first thing you see when you remove the label:



The circles are clips. There are two more on the other side:



This is what the clips look like popped:



This is what you'll first see when you remove the cover:



This is the "top" of protection and sensor circuit:



This is the "bottom" of the circuit:



This is the temperature sensor. It is simply taped in place. This is a component of the protection circuit. This is very important! Make sure to attach this to the replacement cell to avoid an explosion!



This is what we need to focus on. The positive and negative solder pads. I would recommend clipping the leads off and then desoldering the pads to avoid heating up the battery.

hi guys this is my first post here I have a number of Dell 1950III servers and i put Caviar black 1T 64mb SATA drives in them and put it to raid 0. I have the perc 5i with 512mb cache and my max through put is really poor and i need some help to sole the issue.

Min 39.3MB/s
Max 103.7MB/s
Av 89.4MB/s
Acc 10.8ms
burst 289.2Mb/s

I have tried everything i know to get the rate up i mean my desktop PC with onboard raid gets a score of

Min 125.0MB/s
Max 267.8MB/s
Av 175.5MB/s
acc 10.4ms
Burst 119.6MB/s

I have a feeling it is something to do with the SAS/SATA backplane, i have flashed the firmware on everything to the newist i can get but still no luck
Please can you send me some ideas.

Cheers.
