ARECA Owner's Thread (SAS/SATA RAID Cards)

ATWindsor said:
I have two Areca 1260s today, and I have been pretty satisfied with them (the exception being that if something causes a drive or two to fall out, like for instance a loose power cable, often one drive isn't part of the array, and the array needs to be rebuilt). So my plan is to get a Areca 1882-24 with 4 Gig of RAM (if no one convinces me otherwise, is intels offerings a more solid choice for instance?), have that in my main fileserver, and move the two old 1260s too my backup-server, run them in JBOD-mode, and have some sort of software-RAID there (probably the new win8-thing or ZFS).

But where to buy it? Do anybody have a recommended shop where i can get the 1882 at a reasonable price with 4 Gb preinstalled? And shipped reasonably quick? (I do not live in the US, so it mus hit a 10-day-period when I am staying there at a hotel). I used Flickerdown for my old cards, but they seem to not exsist as a store anymore?

To save yourself a bit of coin I would suggest buying the 1G version and adding a 4GB supported DIMM yourself, you will save about $200 doing that. As far as where to buy, newegg usually runs a 10-20% off RAID cards every month or so (get on their mailing list) and that usually gives them the lowest prices around.

Thanks for the tip. However I have no opportunity to wait for something like that, I have to order the last half of may. I visited this page (which seems to be cheaper than newegg, does anyone know anything about this shop?):

http://www.acmemicro.com/listprod.aspx?parent=31

The 4GB-version is about 160 dollars more expensive there. But the savings would be 160$ - Price of compatible EEC-memory. I am not sure if I feel that is worth the hassle.

The company I work at has purchased servers from Acmemicro in the past with good results.

Thanks. I did that. Still no reply after 3 business days.

If I don't hear from them what should I do?

Could I bit copy the data onto new drives and then try some of the techniques alluded to in other posts: Level2... etc?

Thanks again.

Stop press. I got a reply asking me to run the Level2 command and report back to them.

Yep level 2 rescue is usually the next step and better it comes from them, that way they have no excuse versus if you just found the command on a forum and threw it at the card -- because they've insisted that the lvl2 command is case by case and can make things worse in the wrong situations. But more importantly you keep your options open with them in terms of data recovery help in the rare circumstance all other options had been exhausted.

And if lvl2 rescue fails (meaning corrupt raid metadata on the drives which the card can't use) then 3rd step is usually re-creating the raidset/volume in NO-INIT mode using the exact parameters of the original raidset (drive order, stripe size, etc). But cross that bridge once there.

FIXED!

That command did the trick.

Keep an eye on your drive temps in case heat was a factor in the drives falling offline and getting marked out of the array by the controller in the first place.
 
The areca 1882-24 has 6 internal ports for 24 ports. But it also has 1 external port. Can i use this external port at the same time as all the internal, so I can have 28 drives without an expander?
 
@ATWindsor

Sure! That is why Areca calls these card 12/16/24+4 ports. It was working this way since 1680.
 
Hey all,

I have the arc 1261ml. That i right now use in combination with hitachi 7k3000 ultrastar disks. But these diaks are so expensive. Would it be possible to expand my array with 7k3000 deskstar disks?

And are the deskstar a lot less reliable than the ultrastar?

English is not my native language. Don't be to hard on me.

The ultrastars have a higher reliability against unrecoverable errors (10^15 URE vs 10^14), are made for 24/7 operation and are more efficient (faster) for random access server operation. That being said, you CAN mix them into an existing array, but the array will work to the lowest common denominator so you will lose any seek benefit that the ultrastars offer you. If you create a new array with the deskstars, the existing ultrastars will continue to work as fast as they are now in random seek operations in the array they currently live in.
 
Hey guys, whats the word on the 5k4000 and 7k4000 drives? Do they play nice with areca? They're not available where i live right now, but for whatever reason the $/GB ratio is better than the 5/7k3000 drives...

I'm in the market for hdd's now and really dont know what to do. Judging by this thread its basically Hitachi or nothing, which in my case really blows since theyre so expensive.

7k3000 2TB $160
5k3000 3TB $320
7k4000 4TB $380

I live in Norway, and this is what i have to deal with. So yea, the 4TB drives, are they fine?

According to hitachi's spec spreadsheet, the 7k3000 deskstar is rated for 24x7 avaliability.
 
Is this a maximum out of 4x A-Data S396 30 GB SSD's (each is 280/250 MB/s) ?

I'm getting poor write speed about 150 MB/s.

750mb/s is about the maximum you'll get out of a 1231ML. If you were expecting better, keep in mind that the card you are using is nearly 6 years old.
 
odditory said:
As to your question about isolating the ports - what you could do is break the array and set the disks to passthrough disks individually, then fire up HDTune and do a quick read-test on each drive for 10 seconds, abort, next drive. That will make sure all the drives are giving you full speed individually. Dont even bother initializing or formatting them NTFS as HDTune's read bench works at the disk level.
Click to expand...
I got around todo'ing this.

Each drive in passthrough mode worked correctly and on-par with a drive handing off the motherboard with which is the same type & firmware.

On 4 disks, I created some RAID6/RAID5 slices which even at 4-10gb took ages to init. and when I tried to delete the volume while it was init. took out the out-of-band management and caused the computer to hang on shutdown. But volumesets already exposed to the host kept working.

When I get a bit more time, I'll double check my results for performance of RAID1+0, RAID5 & RAID6 volume sets. The RAID1+0 looked about right, but RAID5/6 had some horrible performance for read requests between 64kb-1mb in size.
 


Hi guys,
iam reading now a whole hour this thread because, i am looking for a little solution to rescue my degraded raid5 array, a little watercooled home file server with 16x 2TB WD20EARS drives. configured with 2 raid 5 arrays each 8 drives.

i have tried to fix the problem with Kevin Wang from areca .. butt till now now success

some month ago i bootet up mymachine and it tells me a little problem
i checked the LOG and it shows "Incomplete
RAIDDiscovered" but all drives are online and one is marked as "free" with
one reading error. what should i do now. change the drive ? or recover the
raid set. how shold i do this ? wich options i have now ?

Hello Mr. Wang,

Yesterday i have bootet up the system and i detected last array consitency check was 3 month ago. so if the hot remove dont work i have the option to activate the array and ist degraded, so i would like to copy first the hole data on this degraded array to a other computer. i am a little bit scared to rebuild the array first. if i have a reading errror on a second drivet @ the rebuild session myhole array is lost ?
so i think a better way would be to move as much as i can first to a other system ??

how could i make a "hot remove" could u tell me some more details ? should my system powerd up or powered off, should i go into controller setup screen if i remove the drive or how i must proceed.
i have nothing changed on the array till now. i made one boot into windows and one shutdown. i watched hdd activitiy leds there was no activity till now ( good sign). so my files are untouched on the drives.

Dear Sir/Madam,

in a degraded arrat, not the hole array lost while reading error occure, only the data belongs to the read error sector will lost.
and backup important data is a good reaction before start rebuilding.

and regarding hot remove, it mean you just pull out the hard drive while system running and put it back after a minute. if your hard drives are not hotswapable, it will be risky and not recommended to do a hot remove on these drives.


Best Regards Kevin Wang

Hello,

i have done your suggestion, i have unplugged the "FREE" marked drive and bootet up the system, the volume was still incomplete ( discovered ) when i plugged the old drive in ( "HOT REMOVE" your suggestion ) the drive was recognized as free the log file said device insertet and two seconds later the log file shows an reading error on the old insertet drive now the hole volume is gone and every drive was assigned to the old volume is shown as "free " ....... now iam not able to rebuild or to restore the volume ... oh oh what have i done. please tell me i have NOT lost 12TB data.

please help

with best regards: xx

Dear Sir/Madam,

you will not lost any data in the array as soon as these drives are accessible.

and if the problem presist after you do a hot remove/reinsert on the free drive, you will needed to activate the incompleted raidset to be able to access the volume in this raidset. you can find this feature in the raidset function menu.
but i do not understand why you offline the raidset before test ?
if the array not listed inside, how controller add the drive into the array ?


Best Regards,


Kevin Wang

Hello Mr. Wang,

1. Thanks for this great personal support
2. i made a little mistake and have forgotten a little piece of the configuration of my controller.

I have a 16port controller with 16 drives each 2tb, i have made 2 raid sets each 8drives in raid 5 with 16tb each volume ( in windows usable space each partition 12TB )

raid set 00 is the good one
raid set 01 is the discovered bad one

to make nothing wrong i have taken the first array offline bevor iam doing something in the server ( if i touch the wrong cable @ raid set 00 or something else this raid set would be also degraded )

tha array was taken more times offline because every time i made a restart it was automatically online ?? iam able to change this ??

so i have taken the first raid set 00 offline and after this i have insertet the drive.


i have also a second controller arc1680ix in a second system and there has been 5 days ago, 8 empty drives same size same model. so i made this "hot remove" test there before. i have pulled out a drive, as my test system with the 1680ix was off ( real off - without power plug ) i powered on the system and got a warning like in my other case with the 1160ml. i bootet up and plugged in the disconected drive. it has worked - operation was successful. so the testet this hot remove on a other system and it was ok.

after this i have testet fully motivated it in my main system with the 1160ml and it has not worked, now every drive from the second array 01 is marked as free :-(

now what should i do for the next step :)
------------------------------------------------------------------------------------------------------------------
Helllo Mr. Wang,

could you explain me also the situation why all my drives has been marked as free in 2 seconds after the hot remove ...( hot plug in )

And i have till now no idea how i get my volume online .. all drives are still marked as free ...

Regards: xxx

------------------------------
till now no answer... is anyone able to help me :-(

all drives stil marked as free, nothing have changed in configuration, machine was powered down for 6 month ( have build a whole second machine, also with 16x2tb) ... now i try the step to ask the community

and i think iam the only guy, with a case modded silent server wich is watercooled, havent seen a similiar in this forum.

What motherboard, which slot is the controller in (and what is in the other slots), OS, firmware revs on the areca card, do you have antivirus enabled, which antivirus? If you increase the sample size from 50MB do the sequential write numbers increase?
 
Not that it'll matter with Crystal Disk Mark, but why is your queue depth only 32? What is your stripe size? I don't see it in your screen shot; are you doing RAID6 across 8 x 2TB SATA drives? Why do you have disk write cache set to disabled? Do you have a BBU installed and configured, and enabled?

Seems like what they told you is correct and you just needed to activate the raid set?

Areca has a nice (IMHO) security feature where if a drive doesn't explicitly fail while running (say is disconnected for some reason while the machine is off) it wont automatically activate (degrading the raidset). As long as you dont see message of a failed array then you are good. The read errors can happen from normal disk access (even during startup) although not a good sign during startup.

Seems like you should have been able to activate the array and be done unless more than 1 drive went away during the powercycle but it appears to me that ur drive 12 died during a reboot/powercycle and its erroring out during raid bootup so should be a matter of just disconnecting it and/or activating the raid set and you should be good (degraded ready to rebuild with a new drive).

Here is an example of output you really dont wanna see:

Code:

Can you get a screenshot of the webinterface?

Asus P5WDG2WS Pro
testet controler in both pci-e slots, no diffrece, grapic card is installed @ normal pci slot
no virus scanner
128k @ raid controller and formated with gpt with 64k - both values are the biggest i am able to choose
firmware is the newest one,
other crystal test i will try later
32Q is the biggest value i could choose in the controller menue
 
@ houkouonchi: i have tried a hotplug, pull out drive 12 and push it in, normaly it should rebuild the array or something else, but now a hole array with 8 drives is marked as "free" ...

Are you running BIOS 0905 on the asus? I had a problem with a 1231ML on that board some time ago with 0805 and slow writes.
 
yepp newest bios 0905

but wich step i can do as next ia all my array drives marked as "free" try this signat and repair ...or rebuild witouth init ?? something else ...

could someone post optimal RAID 5 settings with a bbu and Large files, Cache. Ncq so on ...

l@@k so unreal




YEAHHHHH PROBLEM SOLVED ..... write trough must be set disabled to write back .... i have connected a battery pack but with write trough i get so fucking slow performance ... so i have BBUconnected and write back ... oh perfect :)

It looks like the ARC-1882i has a firmware regression for dealing with the older 7k2000 Deskstars (well it's either that or my 1882i is damaged), on the upside the beta firmware shows they are at least working to support 4k physical sector drives. The new options for how the card reacts to SMART failures and drive timeouts is also nice.

Not sure what "Write Same For Initialization" actually is, but I've seen it mentioned in the changelogs before.

it should be a problem on these desktop drives to supporting raid features, we had ever encountered similar issue recently.
you can update controller with attached beta firmware to see if the situation changed.
this beta firmware removed the feature to avoid this kind of issue.

In response to my ARC-1882i management console hardlocking on array initializing hitting 99% and then deleting the volume which requiring a hard reboot to finish the last few percent of a volumn init, and potentially to some horrible read performance issues I've been having.

Not that it'll matter with Crystal Disk Mark, but why is your queue depth only 32? What is your stripe size? I don't see it in your screen shot; are you doing RAID6 across 8 x 2TB SATA drives? Why do you have disk write cache set to disabled? Do you have a BBU installed and configured, and enabled?
Click to expand...
There is no BBU, correctly, installed, as otherwise the hardware monitor would be showing a "charged status". Thus the shitty write speed is because the Areca card isn't doing any write caching and the disks have had thier write cache disabled.

To anyone familiar with the Areca ArcSnmpConf...

Does this Areca provided software utility provide or do anything above and beyond what the Ethernet port SNMP that's included with many of the Areca cards already?
 
What kind of temps are you guys seeing on the 1882? I have the 1882ix-16 model. My cpu temps are really high. Like 90 degrees even with its integrated fan and large heat sink. This is worse than the 1880ix-16 I used to use that had no fan and had the small heat sinks. Strangely the heat sink doesn't feel very hot at all on the outside. I can rest my finger on it no problem. I have it installed now and don't want to pull it out at the moment but does anyone know if these heat sinks come off easy and if some arctic silver or otherwise is in order? Anyone else have this problem? Right now with a desk fan blowing on it the cpu is at 76 degrees while the controller is at 37 degrees. I know the cpu runs hotter but that much??? Finally, what is the max cpu and controller temp for this card? I think the old one used to be 90 cpu and 70 controller.

Controller Name ARC-1882IX-16
Firmware Version V1.50 2012-02-16
BOOT ROM Version V1.50 2012-02-16
PL Firmware Version 12.0.0.0

I just checked an 1882ix-24 at 1.5/1.5/12 firmware. My CPU temp is 50C (122F) and my controller temp is 54C (129F), with little access to the arrray in the past 10 minutes. It is sitting in an HP Proliant server with extremely good cooling (High RPM/CFM fans). (Many of the home servers here will not have this level of cooling so ymmv)

Hi Guys,
Just looking for a little advice. I have an 1880-24ix controller in a Norco clone type chassis (20 drive bays with four drives on each SAS backplane). So, five of the internal ports on the controller are connected via their own SAS cables to the backplanes. The case is fully populated with 20 Samsung HD204UI drives and it is setup as three arrays (one RAID 6 and two RAID 5).

It's all been running fine for just over a year but over the weekend, I started getting alerts that drives were going off-line / being removed and then re-inserted. I then started getting a message that the whole enclosure was going offline and then coming back. Each time I re-started the server, it all came back in normal state and then ran for a few hours before it all happened again. Now however, the controller is not seeing any drives at all and it looks like the internal enclosure I normally see in the config. is missing.

I've tried disconnecting the battery, powering everything off etc but no dice. The drives are all running - I can hear them spin up and head load.

So, do you think that the controller has actually died and I need to RMA or is there anything else I should check ?

Also, I really need to get at the data so I'm considering buying an 1882-24 to use while the other one gets repaired and then I would have a spare in case this happens again. If I did that, can I just drop the 1882-24ix straight in there and it will pick up my RAID configuration from the disks (I think I read somewhere that this would work)?

Any advice appreciated,
Kind Regards.
 
TivoMad-
When the problem started, was it an entire row of drives (bunches of 4) that started going off in unison? Norcos have had some flakey backplanes over the years. It is possible that the controller has just gone tits up. Do you have a note of the config settings of each of the arrays (which drive belonged to which array, their order in the arrays, the stripe size you used to create the array, etc?) With the proper info (You MUST have the proper raidset/volumeset info or bad things will happen!), you will be able to recreate your arrays with the Rescue, signat and NoInit option. Before you do anything, can you post some screenshots of your areca config screens as well as all your logs so we have a better idea of exactly what happened before we start with how to fix things. As far as boards. yes you can substitute the 1882 for the 1880 to import the raidsets. The obvious next question is do you have a current backup of these arrays? What firmware rev is your 1880 at now?
