Ebay was loaded with 5 of them from the same seller last week. I bid on it at 830am PST and it was barebone ( just the card ). Great deal though.

However, how can the going price for the JC881 cable for the BBU be $20-40 ???? I could solder one on for $2.... Anyway, eparts has a good deal but they are out of stock....

Here is the link to the item I won:

Seller was workplaceintegrainc, looks like they were selling for the first time to liquidate some assets.

So I've installed the 5.00-12 and the 2-92-02 versions of MSM for the Perc 6/i using the stock dell firmware. I can only create raid 0, 1, 1e using version 5 and only raid 0 using version 2-92... I have 5 WD 640GB drives all of which are empty now and recognized. They show up as unconfigured. Anyone have an idea?

Bleh, I answered my own question. It appears I have a SAS 6/iR. Given the wording of PERC 6/i in the ebay auction I feel I was misled. I'm going to return this and get a proper 6/i. Would explain my headache with no raid support past 0/1....

That's quite misleading; you could get the seller kicked off eBay for pulling a stunt like that. In any case, you should get a no questions asked refund.

You'd think after doing about 60 sells/buys on ebay I'd have remembered not to leave positive feedback until 10000% sure it is exactly what you paid for. In my haste I left positive feedback, so I'm not sure how that will effect any appeal process on grounds of improper description if it comes to that. Somehow, given the fact the seller was selling 4 items and it was their first 4 transactions on ebay, I'll find they aren't willing to cooperate with me.

I went ahead and spent the 200 for a perc 6/i that has a BBU/cable with it. I'm done with the headache.

This is pretty common practice on ebay. I've emailed dozens of sellers who advertise SAS5i and SAS6i as PERC5i and PERC6i.

Some of them will revise their listing after getting my email, others will email back in very foul language saying I don't know what I'm talking about.

I work in IT supporting around 300 Dell poweredge servers, most of them have PERC5i, 6i, 5E or 6E in them, a few have SAS 5i or 6i so I think I know the difference.,

Yeah I've been getting major pushback from the seller. It's dishonest and just bad practice to list an item as a more expensive item and claim they didn't know. I guess I could blame myself too, if I had taken more time to look at the different boards I would have known it was a SAS 6i, still doesn't excuse their behavior.

Contact eBay - the item was not what was advertised so you are entitled to your money back. You should also be entitled to a refund for return shipping costs etc too - but this might be a little harder to get back. Just tell the seller you will contact the eBay resolution team if they don't sort out your refund pronto.

Worth bearing in mind that it sometimes works the other way too though - the cheapest PERC 6/i I have bought so far (~$20, no bracket or battery but including the stupidly overpriced battery cable) was advertised as a SAS i/R, but the pictures showed it to be a PERC, so I bought it based off the pictures. And got a great deal, safe in the knowledge that I could have sent it back if I received the SAS card as the auction had stated the pictures were of the actual item.

You can still report them even if you've (mistakenly) left positive feedback. Go here. Click "I received an item that does not match the seller's description." And off you go.

Hello,

I was during two weeks searching about a good hw raid card...

I searched about 3ware (LSI), Areca, Adaptec cards, etc...

The "funny" part :

This searches came from the fact i wanted to reproduce at home what many of my customers have at work : a solid RAID "powered" by Dell servers...

And after so long searches, i discovered this thread and realized that i searched all over the world for a solution that was in front of me : i only had to opt to a Dell RAID card ...

I immediately purchased one on Ebay (PERC 6/i) : i'm actually waiting for delivery.

As i didn't find clearly if SMBus issue concerned all PERC cards or only PERC 5/i, i preferred to be careful and bought a nvidia chipset motherboard (Gigabyte GA-73PVM-S2H... also waiting for delivery ).

In the meanwhile, i'm hardly thinking about the hard drives scheme to opt to...

After reading much articles, i decided to opt to RAID 6.

Indeed, my priority is : reliability (only storage home server) and don't care about ultra-high performance (why care ? bottlenecked by gigabit network).

So, i think, RAID 6 is a good choice : any other advice ?

Indeed, my big fear : data loss (as all people, i know...)

And now, i'm actually thinking about the following part : choosing the hard drives...

I know that raid editions are highly recommended but, for budget reasons, i was thinking the following :

perhaps the extra security brought by raid 6 mode will "permit" me to use consumer-grade drives instead of expensive raid edition drives ?

Before all, i just want things to be clear : RAID ISN'T A BACKUP SOLUTION !!!

Whatever my final scheme should be, it will be setup with a backup scheme...

But of course, i'm trying to setup the most reliable and "careless" raid system (at low cost obviously lol )....

So to resume all my explanations, here are the main questions i'd like answers to :

* Does RAID6 seem to you a good mode for reliability ? Or do you advice some better "reliability/disk space" ratio raid mode ?

* Does it permit me, carelessly, to use cheap SATA drives instead of expensive RAID editions ? I invite you to read the following Adaptec article :

"Note: With less expensive, but less reliable SATA disk drives in a configuration that employs RAID 6, it is possible to achieve a higher level of availability than a Fibre Channel Array using RAID 5. This is because the second parity drive in the RAID 6 RAID set can withstand a second failure during a rebuild."

(Source : http://www.adaptec.com/en-US/_common...par_wp.htm#2.5 )

* After many readings and after calculating, i conclude is better to build a raid with much smaller drives than a few big drives (a bunch of 250/500 Go drives instead 4 1To drives), am i right ? In order also to optimize / use cleverly RAID 6 mode...

* Which drives set do you advice ? I've found some people using WD6400AAKS sets with PERC cards... My searches drived me to choosing between Spinpoint F1/F3 sets and WD Caviar sets...

(Indeed : impossible to find any motherboard/hard drives compatibility list for PERC cards, which is normal to not find )

Thank you very much for reading all this post

Sincerely,


XZed
