Perc 6i and SGI expander compatibility

post #1 of 4
Thread Starter 
I recently purchased a Perc 6i for my system and will be throwing 2TB drives in a raid 6 array soon. My current case is becoming very cramped and I only intend on growing this array. Looking around Hot swappable cases are hard to come by on the cheap. I def. want atleast 8 drive bays and individual power/act. lights for each drive so I know which is bad when it goes down. I also like the idea of once cable connecting the expander to the raid card . . less mess inside my server case. I stumbled across this ebay auction for a SGI Omnistar SE3016 Expander. I know SGI makes some decent equipments but will this expander work with my Perc 6? (I heard that SGI used to be very particular on hardware it plays with). Also will this be particularly noisy? I plan on swapping out the fans for much quieter ones as I will be running less than 1/2 the drives for atleast a year but I currently live in a loft with no doors or walls between my first floor computer and second floor bedroom.

As always thank you for your help and I value your collective expertise.


>> Also, been looking around but never find a concise andswer. I have 4x Seagate Green 2TB drives. Will these play nice with the Perc? i have heard both yes and no but never anything first hand.

@OP

The PERC 6/i will not support more than 8 drives regardless of whether the drives are connected to an expander or connected directly - this is a limitation built into the firmware by Dell in order to protect sales of the PERC 6/e, which can see 192 drives (I think).

I've not heard nice things about the Seagates - I remember the Areca guys over on [H]ardforum having issues with them. If you want 2TB drives that play nice with hardware RAID controllers, Hitachi 7K series are good. If you want "green" drives, the new WD Red NASware drives are built specifically to support hardware RAID and as such have TLER built in to facilitate this.

Awesome . . . I was never really planning on running over 8 drives but none of the 8 bay cases/backpanes I saw were of high quality/decent price for my tastes. Also I thought the 6i could handle 16 drives as per this Dell website?

>> Regardless I have decided to get an SGI Server/expander combo to handle my server needs. This way I dont have to worry about controller/expander/motherboard compatibility issues. Unfortunately I did not know about the raid issues when i purchased these 2 new 2TB seagate drives. Seagate has always been my go-to and I will stay away from WD at all costs ATM (Every WD I have owned has failed prematurely (including the 2TB these seagates were replacing). From now on I will look at Hitachi and Samsung a little bit more closely.

Just to be sure you are saying that the seagates are essentially useless correct? . . . Are there any non-WD green drives that are decent for raid? It will be primarily for movie/TV Show streaming and some misc use so only really using it 4-6 hours a day, all in one block.



>>>>EDIT Juse looked at my Seagates . .they are 7200 RPM, Thankfully due to Tigerdirects terrible stocking system I must have picked up the wrong ones since they were similar priced and same section. Does this raid issue pertain to the 7200 RPM ST2000DM01 Seagates? . . . I will do search now but obv. any perspective will be helpful.

PERC 6/i - Perhaps my info is out of date, I'm sure I got that info from the sticky - perhaps DuckieHo would like to comment if he's around? Or you could PM him to verify - perhaps Dell have upgraded the firmware?

Hard Drives - look here for a basic rule of thumb. Look here for all of the posts in the Areca thread which mention Seagate.

That's not to say that your drives are useless, but Seagates have traditionally been the most problematic. Bear in mind that this applies to consumer drives - their enterprise kit is in fact very good.

Non-WD green drives? Samsung HD204UI (now known as the Seagate ST2000DL004) behave well in RAID but the TLER setting does not survive a power cycle. However, you should look at the WD Red NASware line - I'll likely be buying these from now on. Look here for early impressions.
