I am tearing my hair out with a LSI Megaraid 8480E having the same issue. The card is detected, I can access it in Storage Manager, but it will not see the drives. I did not know there was a difference in cables host-to-target. I actually bought two cables and neither works. That card uses SFF8470 ports which are much harder to come by than the ones on the PERC....LOL. And check out the price. eek.gifeek.gif

How in the world can you tell which way the cable is set for??? I don't remember noticing any distinction when I bought either of them, trying to find the invoice for them to see where I bought them from. I am kinda hesitant to buy that one I linked to, since I have already spent about $130 on cables that don't work.

This is "the one way" cable - from card to drives only - "External SAS to SATA Breakout Cable - 4x SAS (SFF-8470 Host) to (4) SATA (Device)".

What drives do you have ?

I bought these cables:

The photo you posted is not SATA, I did check the link and skim through that seller's other items and found this which looks like what I need.

I just hate to buy another one from eBay that is SO much cheaper than retail.......

I have been doing some testing with a small office server I am building.

I decided to at least upgrade from the stock 256MB to 512MB on the
PERC 5/i.

I also found a couple 1GB sticks that I thought should work in the card as well and ended up picking them up to do some testing.

My findings are as follows:

I am running RAID 10 with 4x Samsung F4 320GB SATA drives.

HDTune: 512MB stick shows increased performance when doing the 256MB File test. The 256MB stick slows down to ~300MB/s on the 256MB test while the 512MB stick gets almost 700MB/s.

The 1GB stick shows the same performance as the 512MB stick on the 256MB file test. The 1GB stick shows very strange performance on the 512MB test. Near the end of the test the read performance tanks... very strange. I thought it may be an issue with HDTune so I decided to do some testing with Sisoft Sandra and Passmark.

In Sifoft Sandra the 1GB stick shows a slight performance increase over the 512MB stick. In Passmark, the 1GB stick consistently shows ~20MB/s increase in speed over the 512MB stick.

hi, which 1GB module did you use that was recognized by the PERC 5/I? can you share a link of where you sourced it?

SAS-type connectors work just fine on SATA drives. In fact I use a set on my 6/i with 4 of my RE3s - means I can use the SATA drive connectors for half my drives, and the 'molex' drive power connectors for the other 4 so I don't need any adapters as my PSU doesn't have 8 SATA power connectors.

Either force write-back (best) or enable the drive caches (better than nothing) if you want better performance. But buy a battery - the added cost over the card & 8 drives is minimal...

what do you think? this is better?
yes, you are right... I think i will buy a BBU for this card

I purchased a set of 2 of these off of Ebay:

They are made by Micron. The markings are:

MT9HTF12872PY-667E1 200916 CBNDPD0001
1GB 1RX8 PC2-5300P-555-13-F0
1GB, DDR2, 667, CL5, ECC, REG

I scoured Ebay for quite a while before I found them. I just used the specs off of the Wiki to search for what it said "should be" compatible according to the controller spec sheet.

Any DDR2-400 or higher ECC Registered stick 1GB or below with a configuration of 1rx8 or 1rx16 should work with the PERC 5/i. They also must be single sided.

So these should work:

yep, that looks a lot better... but i wouldnt run write back on production data without a UPS or a BBU.
