PERC 5/i RAID Card: Tips and Benchmarks - Page 365

post #3641 of 7276
Lately my PERC5i has started to cause my computer to hang or reboot every few hours randomly.

I've reseated the card, I've updated to lates LSI firmware, latest drivers etc.

Not sure why its doing that. the only thing I can think of is maybe heat.

I've upgraded from a 45 watt dual core processor to a 95 watt quad core.
so maybe the additional heat in the case is causing the IOP to over heat

I do have a low speed 92mm fan blowing at the PERC5i.

I've read through about 200 pages of this thread, but didn't see anything similar.

anyone of a good suggestion on where to find a good heatsink for this thing?

I use an old Pentium/Pentium II heatsink I had lying around, with a few little cuts out so it will fit. Allows much lower airflow to keep it cool to the touch.

Next time I have my camera handy I will try and remember to take a pic. Basically use any old heatsink you have lying around that you can make fit - the stock heatsink is tiny, so anything you can put on with more surface area will be an improvement.

LOL, the last time I read through this entire thread, it took me six hours, and the thread was only half as long!

I've did my Perc5 mod today, here are the results if someone is interested :-)

- Heatsink for IOP333 cpu: Enzotech CNB-S1L.
http://www.enzotechnology.com/cnb_s1l.htm

- Small VGA ram heatsinks: Zalman ZM-RHS1.
I've placed two of them on the chip in the middle.
http://www.zalman.com/ENG/product/Pr...ad.asp?idx=136

- Thermal paste: Artic Cooling MX-2.
http://www.arctic-cooling.com/further_prod2.php?idx=140

Enzotech heatsink + Thermal paste


Polished surface


Zalman heatsinks


Enzotech heatsink attached


My low rpm 120mm fan in the sidepanel of my case wasn't enough to keep the heatsink cool, so i've attached a small fan to the heatsink with tie-raps.
Now i can touch the heatsink longer then 10secs.

I hope it keeps cool enough when i connect some drives in raid5...

Yep - but my server is underneath one of my printers and my switch, wedged in between my desk, a bookcase and my UPS...

Maybe I should have said 'next time I have it accessible I will take a photo'.

Nice mod though - mine is basically similar, but my heatsink is taller (takes up 2 slots) and not as long (it barely reaches past the mount points). I just selected a relatively lightweight heatsink with a base the same thickness as the OEM one, then trimmed off the fins that got in the way of the OEM clip.

Hi I recently bought a PERC 6/i. I've seen some notes here and there which I can first off correct:
  • MSM does run on Windows 2008 R2 x64
  • The Perc 6/i is mostly compared to the LSI 8888ELP but can rather be compared to the LSI 8708ELP. Reason; The 8888 has switchable external and internal connectors while the 8708 is only internal based. It only has 128MB ram while the 8888 has 512MB ram. So the Perc 6/i is in the middle with 256MB ram.
  • You can flash the LSI firmware on it from here. I'm currently running it. Only drawback, which other people also say, is that you can't access the CTRL+R boot manager. But, if you really need it besides manageing it from linux/windows then you can just simply flash the Dell firmware on it again and access it that way. After you're done you can flash it back to the LSI firmware. The flashing doesn't make any changes like losing your RAID configurations.
  • You can use the drivers from the above LSI link. However, if you are running Windows 2008 R2 x64 you MUST use the windows built-in driver. When updating the driver just search for it in the built-in driver list. If you don't your windows will be trashed after a reboot and will be very hard to recover if not impossible.
.
I've tested all the above on a AMD 64 3200+, 2GB ram, Gigabyte K8N Ultra SLI motherboard (did not need SMbus mod because it's got nVidia chipset). OS; Windows Server 2003 R2 x86 and x64, Windows Server 2008 R2 x64.

I've also got a question. I bought 2x Samsung EcoGreen F2 EG HD154UI 1.5TB drives. I was going to buy 4x more for a RAID5/6 set untill I came across posts about SCT error control, CCTL for samsung in this case. I've tested the drives with HDAT2 and it does support the feature but it's default setting is 0 seconds so unusable. You can however set it at for example 7 seconds for read/write but after a cold/warm reset the settings are gone again.

I've searched everywhere and as far as I know it's not possible to make these changes permanent. Can anybody confirm this? Also, when I'll have a RAID5/6 set of about 6TB of usable data there is going to be a lot of important data on it. I wouldn't want to loose it of course. However seeing the posts about RAID setups with drives like these which do not have SCT set (or at 0 seconds) it looks to me like these should not be used, am I correct? Because with this, from what I've read, you'll get a degraded RAID set now and then to quite often with the need for a rebuild (if you're lucky).

I've looked at the prices for drives which do have SCT set but they are quite expensive. 2/3 extra in the price. I'm wondering; is there any other solution to this, can I just stay with these samsung drives without worrying, or should I really just buy drives with SCT (which I think won't fit my budget with 6x drives)???

Sorry for the long post...
