Areca 1882, the new speed King?

[Sandon]

That kind of sounds like a incompatability with the SAS expander. Find out what model of SAS expander for sure. I have tested the 1880 and 1882 with the 6 GB LSI expander and I know it works for sure (it doesn't with the 3 GB one).

Did you change the percentage of background rebuild percentage so it is 80% instead of the default 20%? That will affect the speed of a background init by a large amount. I have found the ARC-1882 is very fast though. With 80% setting I have seen the ARC-1222 init 24x3TB ultrastar 7200 RPM hitachi disks in just over 8 hours (very fast) but it was a foreground init which makes it go quite a bit faster.

For example my ARC-1880 with 30x3TB 5700 RPM coolspin hitachi's did a *background* init in:

2011-09-04 05:21:17 DATA 2 VOLUME Complete Init 040:39:42


The rebuild was quite a bit faster though and took about 25 hours. Granted this is a *huge* 90TB array.

Hey Sandon, thanks for the quick reply- that is a massive couple of volumes you've got; under the information listed on the areca webgui the sans-digital enclosure is using an LSI expander and it is a 6GB version as the whole enclosure is capable of 6GB- I don't know the specific model of the LSI expander, but I will find out tomorrow and update; as for the initialization, I did not change the background percentage- I actually did a foreground initialization and that took 4.5 days. If there is a percentage setting to change for foreground initialization too then I did not set that past the default, so that could be the problem there...

I'm waiting for the rebuild to finish before I mess around with it anymore, but one other thing I wanted to mention is that I kept getting timeout errors when I was transferring to the hitachi volume, after foreground initialization, when I was in the regular windows environment transferring at about 150 MB/s (which is the max transfer rate I have been able to get with this setup- my source volume for the transfer was the wd-re4 green hard drives volume also in the same enclosure so I assumed that slowed down the transfer rate, my OS hard drives are two Corsair Force GT 120GB SSDs in Raid 0 on the motherboard intel 6GB controller), but I did not get the same issue (timeouts) when I went into safe mode for windows and the transfer topped out at about 50 MB/s- obviously it took quite a bit more time for the transfer to finish though. I am running windows 7 ultimate x64 and it is a clean install I did just two days ago with nothing but drivers, windows updates, eset smart security, chrome, and firefox installed since then.

Updated info: spoke with Sansdigital and they said it is not a specific model expander since it is built for their application, but it has been tested with the 1882x and confirmed that it is compatible.

I have verified compatability of the LSI 6GB sas expander used in a supermicro chasis. Here is what hw info on the cli lists:

This setup only showed a timeout error once and the disk later failed and has been fine sine then. It shows read/write speeds just around 2 gigabytes/sec. What your event history look like and hw info? I am thinking the expander is not really compatible or something.

[Smikk02]

Finally figured it out with some help from Areca tech support- turns out it was the min-sas cable I was using; thanks for confirming that it was not the expander. I'm hitting 2.2GB/s read and almost 1000MB/s write now with the hitachi drives in a raid6 config. according to the ATTO disk benchmark I ran this weekend.

I have an 1882ix-12 on the way and want to get the 4GB module for it. Are there any known modules that will work besides the one specially designed for it?

No, but this is xtremesystems! Who cares about the prize

Ok I know, it sux!

[Tutto]

I hear ya. I went the hard route when I got my 1880 and tried to save a few bucks and it cost me more in aggravation than anything else. I picked the controller up on NewEgg open box for $600 and got the battery for $92 so I shouldn't be complaining about the price of the memory

$600 for 1880-8i or 1880-12/16?

[Tutto]

I got an 1882ix-12 with the ARC-6120-T121 Battery for a little under $700

[Computurd]

i have one with a 4gb module if anyone is interested

[Tutto]

i have one with a 4gb module if anyone is interested

Which model do you have and why are you selling it?

[Computurd]

1880IX-12 and the reason i am selling it is because i have 7 different 6GB/s RAID controllers...i dont use them very much LOL. only use one at any given time for my personal use. This is the last one i actually purchased myself, and i dont need it

Can you send to Norway

I need one more Areca IX

I have the same controller I'll be selling soon as well. Just upgraded to the 1882-12. 2 things I noticed immediately: 1. It takes less than half as long to initialize as the 1880. A few times it has initialized in 15-16 seconds. The best I've even seen with the 1880 is close to 40 seconds. 2. The beeper has finally been muted to an acceptable level. I'm noticing it runs considerably warmer than the 1880 did. I have a fan directly under the controller and the 1880 operated at 45-48C. The 1882 is sitting at 56-58C and that's with a fan blowing on it. Do you think it would help to remount the heatsink or is that a normal temp because of the dual core cpu?

[Computurd]

the 1882 ROC is a higher clocked LSI ROC. so yes, it runs hotter. need to put a different HS on there, preferably copper. and get a small fan on it. you can buy some good copper hs and fan combos that are very slim.

What would you recommend. I have an 80mm fan directly under the 1882 but it's still operating at nearly 65C and it bothers me to see it that high.

[Computurd]

yes they are good up to 100C according to Areca. I actually ran mine with water, and that gives astounding results. there are some other 'cool' (ugh) solutions: heres the best imo:

http://www.frozencpu.com/products/55...?tl=g40c16s500
I personally have a few of these around, and they are very sexy. i do have small fans that are around as well, and use them in conjunction with digital thermal probes and run them on a temp curve with a T-Balancer. so its good to have extraneous gear, but withstanding that:

http://www.frozencpu.com/products/13...?tl=g40c16s501

seriously, its good to have these laying around. i run aftermarket cooling on all my gear, it is just that much better, in the 40C range better in some cases.

[Computurd]

idle with air:

under load, after being watercooled, ROFL!!

[Hondacity]

86c on water? thats bad. maybe that temperature is on that passive heatsink? what psu do you have?

[Computurd]

nope that was idle with air cooling. the second pic is under load with water, i will clarify

a sidestory btw, they had big issues with the original stock heatsinks on that card, later they swapped to a full board HS that is on all Areca IX models.

[Tutto]

100C Ouch! Will the Enzotech fit without modification. Has anyone removed the heatsink from an 1882? Does it come off easily? Does the 1882 use 2 heatsinks like the 1880?

[Computurd]

no mods, other than the connection hardware, i used bolt and nut approach. I did have to modify some plastic washers to fit around a component that was right next to the hole so that they wouldnt interfere. the heatsink itself though is cherry 1882 if it is IX uses 2. only IX version have 2, one is the expander. the expandeer doesnt need extra cooling as much, but if yer already there

[felix_w]

Computurd, have you seen performance improvement due to water cooling this card, or is it just for expanding it's usable life ?

Does the 1882ix-12 heatsink come off easily? What's the chance of damaging the cpu?
