PERC 5/i RAID Card: Tips and Benchmarks - Page 574

post #5731 of 7150
I recently put together a 6 (1.5TB) drive RAID 6 array and I'm getting sustained transfers of ~65-70MB/Sec (host operating system is server 2008 r2 with sp1 - if that makes a difference). This can't be right as I Had a RAID 5 array with three of these drives and my transfers were ~120MB/Sec. This is with Write Back and Adaptive Read Ahead enabled on the controller (my network capable of better than this). mad.gif Any ideas?

^ @ svortevik: Every time I used one of these with an ICH9R chipset, I needed the pin-mod.

Using HDTune for your benchmarks? if so go in to the options\settings and change the blocksize to 8MB.

I've tested different combinations of the 5/i, 6/i, 5/e and 6/e - no problems at all smile.gif

Enzotech
CNB-S1L
MOS-C10

But as A_Man_Eating_Duck said you can use other heatsinks and fit the original wire holder onto them.

I have a system. S3420 + PERC5i + 2x1T SATA HDD + ESXi4.1
I would like to upgrade the board and CPU to the new one S1200BTS + E3-1230
Can I just move the raid card and the HDDs to the new machine, and the ESXi4.1 will boot up?
Or I have to re-install the ESXi4.1 and then restoe the guest OSs?

By the way, does the pin mod of PERC5i needed for Intel's new board S1200BTS?

Thanks!

Anyone know where to get a SFF-8484 to 4 SATA passthrough with RIGHT angle connectors?

Also, could someone please explain the difference between passthrough, crossover, and backplane cables, please? Is there any way to tell them apart?

I came across this thread some time ago and used the information within to configure my RAID 5 setup.

1 x PERC 5/e 256RAM w/ BBU ($25 on eBay)
2 x SFF-8470 infiniband SAS to 4 SATA Hard Disk cable ($25 each on eBay)
5 x Seagate Barracuda 7200.11 ST31500341AS 1.5TB 7200 RPM SATA 3.0Gb/s (Aprox $89 - $109 each @ newegg)
1 x ICY DOCK MB455SPF-B 5 in 3 SATA I, II & III Hot-Swap Internal Backplane Raid Cage Module ($110 @ Newegg)

The RAID5 array is my current boot volume, therefore during the benchmarking of the Performance Benchmarking the OS was competing for resources....... at times, the disk was in use by OS and affected the benchmark.

OS: Windows 7 64bit Premium

Can someone please help me a bit?

So I installed the perc 5i card and loaded bios defaults.

- Each time i exit the perc bios my computer hangs and I have to cut the power. Any solution to this? It only happens when exiting the perc bios.

- Is it still recommended to stay on Dell perc 5 firmware or the LSI firmware?

- Is there any software I can use to manage the card when using the dell firmware?

- During boot I get a message about missing battery. I have a battery connected, so is the battery defect or is there anything I am missing?

- Finally, can I use these cables from dealextreme?

Serach this thread for cold / hot boot.

With LSI firmware you can create bigger stripes - but you won't be able to use your volume with DELL firmware.

No idea ... maybe LSI MegaRaid will handle it ?

Battery is dead.

Can you please explaine this part for me?

"With LSI firmware you can create bigger stripes"

I read somewhere that arrays over 5TB will be corrupted using the LSI firmware. Is this correct?

Also, is it possible that the battery only needs to be recharged? Someone told me I had to let the server stay off for 24 hours with the card and battery connected for it to recharge.
