PPC G5 compatibility of Areca PCIE RAID controller arc-1280?

Subject: Mac compatibility of Areca ARC-1280 24 ports PCI Express to SATA II RAID adapter.
At Areca's Internet site ( www.areca.com.tw) consumers can read at pages concerning arc-1280 card that: « The SATA RAID controllers support broad operating systems including ... MAC ... ».
At Specifications page, under: Operating system, it is written: « Mac OS X (no_bootable) ».
Absolutely no other warning appear about MAC owners.
So, if you are just a basic computer consumer, you are now strongly tempted to believe that if you got a MAC with PCIExpress technology & OS X, you can safely buy arc 1280 PCIE.
This is because (nearly) everyone knows that in real pragmatic actual life OS X exclusively runs on Apple Mac machines. In the case of arc-1280, as it is a PCIExpress adapter, only two Apple Mac models are possible: the very recent MACPro (Intel cpu based) & late 2005 PPC G5 dualcore (IBM cpu based). As Areca mentions nowhere any warning between MACPro & G5 dualcore, only owners of either of those PCIE machines may logically have the opportunity to run OS X with an arc-1280 connected!
If you are a little bit more paranoïd, before to buy such an expensive adapter, you will check if there are other stuffs to confirm your deductions. You then will find Areca's online user's manual 3.2, where it is stated that a bios configuration utility, contained into card's firmware, is « OS independant » & can be accessed at startup by pressing TAB or F6. About « MAC X » driver installation, user is invited to follow a readme.txt (that in fact does not exist nowhere). It is the same for archttp proxy server installation, which is also asserted to support Mac OS.
Moreover, a Mac driver is freely downloadable online, called arcmsr-1.3.1.pkg. Now you are ready to trust!
Having arc-1280 plugged, you start your Mac (happy to hear that card beep after startup) then install driver (the same is present online & on Areca's companion CD). A text appear:
« This driver supports...arc 1280...PCIE... Please note that this is a pre-release version of the driver for testing purpose, and is *NOT * for general distribution. ». But installation completes succesfully and you pay no attention to this frightening sentence hidden into Areca's driver package.
What then arise when you have your computer restarted? Nothing: except the beep at startup, Areca's high end Raid controller simply do not appear anywhere into Mac OS X!
As I cannot afford paying more than 1200 euro for just a startup beep, I decided to require help from distributor & Areca's very enigmatic support. Lastly distributor decided to try with another arc-1280 which was as useless on my Mac than the first one. I again protested, Areca's support seeming to have totally resign for quite a lot of time now, distributor blaming me not to have been carefull enough ?!
Distributor ask me now to re-send back the card. They will try to get their money back from Areca, then maybe will I have my money back ? They asked me to write a letter with a description of the problem & why I want a full refund.
This is now done, hoping this will help to avoid further misinformation.

MacGurus PCIE which are supported.
I saw the Areca reviewed xbitlabs
AMUG http://www.amug.com does great reviews of Mac compatible drives, enclosures, and controllers.

On-board RAID and PCI RAID controller

Hello everybody,
I am new to the forum. So, please excuse me if that topic was already covered...
I have MSI MAX2-LR (MS-6398E) board. It works just fine, no problem so far. Though I have 2 problems with add-on cards:
1. I was planning to use on-board RAID and additional PCI RAID controller = FastTrack 100 TX2 to cover 6 hard drives into 2 mirrored sets: 4drives one and 2 drives the other.
It doesn't work! I can use either on-board RAID or PCI RAID. As soon as I have any drive connected to on-board RAID, the PCI RAID disappeares. If I have no drives connected to on-board RAID, I can see both RAID controllers, they have different I/O and IRQs, and PCI RAID is working just fine. If only I connect one drive to the on-board RAID, it gets activated on startup, and the other one disappeares. :O
I believe it's a BIOS bug. I wander, if that can be fixed easily????? :D
2. I have a new Matrox Video card = Parhelia. It doesn't work in AGP slot! System doesn't recognize it, and beeps non-stop. I am dealing with Matrox Tech Support on that matter. ?(
Maybe, it's a known issue, and somebody can save me time by telling what's that about.
Appreciate any imput. Have a great weekend.!!! :]

Hey I also have the same Raid card and also the Matrox Parhelia, and I see that you also have some problems with the card I got also problems with the card, but they couldnt help me at theire forums (http://forum.matrox.com/mgaforum/Forum10/HTML/005085.html), I hope we have got more luck here :D

K8N master2-far doesn't detect Areca 1220 raid controller

Today i purchased the last components for my system. Everything works perfectly except for my Areca 1220 8x pci-e raid controller. As i feared the controller is nowhere to be seen, not in the bios, not in windows. I already had bios version v1.10 but flashed the bios version on the msi site anyway. Nothing changed. On the msi site under "QVL" i see my Areca at the bottom of the list. Does that mean that this MB can work with this controller? What must i do to make it work? I think i have to see it at least in the bios!
Your help is appreciated. Now 5x 300 GB of storage is doing nothing.

Maybe you need to update the cards firmware.
I already looked into that matter and found out that the only way to upgrade the firmware or bios is to use their http tool McRAID Storage Manager. This of course is done in windows. Now windows doesn't see my Areca 1200 and so McRAID doesn't see it either. I can't update my Areca.
This problem is well known by the motherboard manufacturers. Let me quote something from the Areca site:
Q10150407 - Is there any socket 939 motherboards that work with your model ARC-1210 raid controller? In a SLI board I would use one 16x slot for Graphics card.
Our PCIe ARC-12xx series controller uses Intel IOP332/333 processor. The Intel high performance IOP (IOP331/332/333) has integrated the bridge chip in the controller. But the original NVIDIA nForce4 SLI chipset BIOS has the problem after Bridge IRQ routing. All controllers use Intel new IOP 332/333, such as Areca, Intel, and LSI have the same IRQ routing problem. Those NVIDIA 939 M/Bs can be worked in the Windows environment. Due to the Windows system takes over the BIOS job, and Linux & FreeBSD need to use the M/B BIOS, so it has problem with our PCIe controller.
Currently, DFI, Ausu, MSI and Gigabyte have BIOS to solve the problem. If you have problem in this kind of mainboard, please try to manufacture latest BIOS.
We have tested DFI Lanparty NF4 SLI & ASUS A8N-SLI Deluxe, and Asus A8N-SLI Premium. It works very well with our firmware 1.38 and newest mainboard BIOS. Try to swap the graphic and our controller, if you find some warm boot problem in the Asus A8N-SLI Premium.
I still think i need an updated bios for the k8n master2-far (ms-9620). The fact remains that there are problems reported with every SLI motherboard. I knew this already from the socket 939 platforms. I was sceptical about the k8n master2-far but thought that a server MB should have no problems. I did ask a question about this however at the shop where i bought this MB. I even found an reply from you to another user who had similar concerns about the Areca controllers and an SLI MB. You said that it should not be a problem. Even so i always kept the possibily open that this problem can happen. And here i am
Thanks for your help. More input is always appreciated as i am still waiting for an answer from MSI in the Netherlands about this problem. Right now my server is doing nothing. I hope my raid controller will work very soon.

I need help getting the right PCIe Raid Controller card.

I have a Mac Pro 3.33 GHz (6 core) computer running 10.8.2. I purchased a Sans Digital TR4M+ http://www.sansdigital.com/towerraid-/tr4mplus.html which includes a Highpoint RR622 card but it's not bootable. I need a non-expensive card which is bootable. I'm currently using the drives in JBOD mode.
Any suggestions?
Thanks!

I'm currently using the drives in JBOD mode.
The RAID features built into Disk Utility support JBOD, Mirroring, and Striping without the use of a card.
RAID methods that require checksum calculation, (e.g., RAID 5) always require a card to provide adequate speed.
Consider whether you really NEED your Mac OS X Boot Volume to be on a RAID at all. A great deal of its data is either invariant (Mac OS X code and Applications code) or temporary ( caches). If damaged, Mac OS X and Applications can be rebuilt from DVDs in a few hours.
Moving the Users files off to another Volume is a great way to speed up your Mac Pro, since it reduces competition for the busy Boot Drive.

H61M-P31 motherboard and RAID Controller

Hi
I have a pc that I want use as a home server, and has the following hardware
Mother board: H61M-P31
CPU: Intel Pentium G620 2.6GHz Dual Core
Memory: 8GB DDR3
Hard disks 1x3GB, 2x2GB 1x1GB
OS: Windows Home Server 2011
I have already made one expensive purchase of a RAID controller that didn’t fit the mother board and don’t want to do that again so I’m asking anyone who has any experience with this mother board and/or RAID controllers what are my options, ideally I would want a 4port card.
Can anyone advise me on what to do.
Thanks
Chris

Was the card you purchased a PCI or PCIe model? if the one you got was PCI then of course it would not fit as there are no PCI slots. Get a PCIe version and it should fit in the lower black PCIe slot.
According to this it's PCI not PCIe

Areca Raid Controller - ArcHTTP - does not work

Areca Raid Controller - ArcHTTP - does not work - in need your help !!!
I am running Win 7pro, 64 bit, 24 MB RAM
Areca 1680 controlls Raid 3 7TB and Raid0 1TB. McRaid works fine.
1. Areca ArchHTTP V 1.85 is installd fine
2. When opening ArchHTTP-GUI it is showing:
     a. Controller #01(PCI): Port 81 running
     b. Cfg Assistent:          Port 82 running
   Application started, 1 contoller found, launch...........:81
3. when i activate Cfg Assistant and launch Browser, ARCHTTP - Configurations opens
4. when i activate Controller #01(PCI) and launch Browser, the website for unsername and password opens
5. after filling in user pandpassword ....nothing happens, the website doesnot open. It seems that i could not be found.
Any idea, thanks for help
klfi

This is likely do to new Phishing or Popup rules in IE9. Most web based controller management utility's do not show up as a valid website since they use local host or internal IP addresses. I know Areca has in the past used Java for their utility which also trips many of those rules. Try adding the web utility as a trusted website.

RD330 - using PCIe-based SSD and on-board RAID controller at the same time?

I've got a RD330 (4304-E1U) with the on-motherboard RAID controller and an OCZ Z-Drive R4 PCIe-based SSD. Basically the SSD looks to the system like a PCIe SATA controller with a single SATA disk attached. If I leave the on-board RAID disabled in the BIOS (Setup -> Advanced -> Sata/SAS Configuration -> Disable SCU Devices=ENABLED), then the system sees the OCZ drive just fine and I can select it as my boot device. Works like a champ, screaming fast.
I *also* need access to the disks attached to the built-in SAS backplane on the server, but if the on-board RAID is turned off, then you can't access those disks. When you go into the BIOS setup and turn on the on-board RAID (Setup -> Advanced -> SATA/SAS Configuration -> Disable SCU Devices=DISABLED), then the LSI RAID array configuration shows up during POST (as expected) but the OCZ messages do NOT appear during POST, and the OCZ no longer shows up in the BIOS as a boot device. It's like the SSD isn't even there when the on-board RAID is turned on.
I don't really need any RAID functionality on those disks, I just need access to them from the OS, but I need to boot from the SSD in the PCIe slot. Is there a way for both the on-board RAID controller *AND* an additional PCIe disk controller to be active at the same time?

I have had a 2.0 USB hub connected to the USP port on my AEBS for almost a year for a printer and a HD. Initially I had intermittent connectivity to the HD but never the printer. As Apple upgraded the software/firmware for the AEBS, the problems have stopped. Reliability has been 100% for several months. Go for it.

Brian

Shopping For A RAID Controller

I have seen the Areca brand name on here many times, so I assume they are the best for what we do. But, there are so many models that I have no idea what to look for. I probably won't ever have more than 4 or 6 storage drives plus an SSD system drive. Maybe a couple of external drives and an NAS.
If I have Windows 7 64-bit
i7-2600k processor
ASUS P8P67 Pro motherboard
32 GB RAM 1600
GeForce GTX 580 Amp! from Zotac
AX850 PSU from Corsair
Every component is reasonably fast, bu I am sick of the senseless limitations of this mootherboard. My drives are aging so they need to be replaced.
Which specs are important for video editing? Which brand and models are most popular and shoould I wait for some new release?
Another thought - If a RAID controller is over $400 US, Is it more cost-effective to upgrade to a more capable motherboard/processor with all the ports I need?

What to look for
Brand
Areca or LSI
Ports
8 or more
Card
PCIe-3.0 8x
Cache
512 MB or more
Multi-lane
SFF-8087/8088
Examples
Areca ARC-1882 series or LSI MegaRAID 9285
Warning: You have to realize that on your motherboard adding a dedicated raid controller will entail that your video card will throttle down from PCIe-16x to PCIe-8x mode, resulting in a 10 - 15% performance penalty, due to limitations of the chipset. A dedicated raid controller, especially with around 6 disks always outperforms an on-board raid by a wide margin. To see some benchmark results, look here: Reflections
To see what meets your requirements, also consider the raid level you want to use. If raid3 or raid30, then LSI is out. You can check out what controllers are popular here: Detailed Results but you have to be registered and logged in to access the page.

Which RAID controller do I choose?

Hi forum. I'm waiting for my Asus P9X79-E WS board to arrive this week and I will be using RAID 0 with a separate daily backup drive for it. Before I can afford high end RAID controllers like the Areca etc, I will have to use the onboard controllers. It comes with the options below, which do I choose? I will be raiding two Seagate 3tb 7200rpm drives for editing. I have 3 SSDs for the rest, like os/cache etc...
Intel® X79 chipset :
2 x SATA 6Gb/s port(s), white
4 x SATA 3Gb/s port(s), blue
Support Raid 0, 1, 5, 10
Marvell® PCIe 9230 controller :
4 x SATA 6Gb/s port(s), white
Support Raid 0, 1, 10
ASMedia® PCIe SATA controller :
2 x eSATA 6Gb/s port(s), red
Support port multiplier support
Product Page:
Motherboards - P9X79-E WS

This is not an answer to your question but I just found a way around the SATA III port limitation with an extremely high speed RAID equivalent that does not require a SATA inteface and is not a RAID configuration. It is a new small PCIe interface card that delivers in any system that has a spare PCIe x4 connector with two available lane to over 700 MB/seconds read operation and over 530 MB/seconds in write operations. All it requires is a PCIe version 2 x4 connector. See below:for tests on my old x58 motherboard.
These are real performance numbers equivalent to a RAID 0 array of 3 to 4 high performance hard disk drives. Of course you do not have the capacity of the hard drive array but by moving past projects to slower drives and reusing the 256 or 512 GB ($300 USD/ $600 USD) SSD drives you maintain the performance. These drives are warranted for 5 years. Actually tested with our PPBM6/7 benchmark with export of our Adobe Premiere Pro Disk I/O timeline I have a measured write rate of 561 MB/second.

Installing Esata PCI-e controller cards

I have an IdeaCenter K450 and I have installed (2) two port esata controllers and niether of them is recognized. It does not ask for drivers or a installation CD. My second question is, there difference between an esata Raid controller and an esata controller?

I've to admit, it's new to me, and I believed to many others as well.
How old do you feel PCIE technology is?
To me, 3 years ago, Intel annouces PCIE platform to take over AGP and PCI on the number of parity bits handled to make smoother and faster communication with the board.
About 1 year later, nvidia annouces SLi to bridge 2 PCIE x16 GPUs for faster performance, following by ATI's Crossfire several months later.
If PCIE was really mature, all PCI slots would be simply phased out today on a motherboard. To me, the reason for the standard PCI to remain on a board is like a fall back plan, where makers do not jumped onto the bandwagon to start rolling out masses of PCIE cards. Probably high cost, probably more R&Ds needed due to compatibility issues, this I'm really not sure.
All in all, some have success and some have not, which is why I said test and trial.

PCIe eSATA controller and drive case

Can someone recommend the best external backup to purchase? I don't quite understand the difference between a regular external hard drive, like something that WD makes, versus an PCIe eSATA controller and drive case. What is all of that? Do I really need such a thing, and is it better?
Thanks.

Dear kpdesigns,
No one knows what you need or want but you. I can provide some ideas of various external storage options that are available for the Mac Pro. The various storage protocols differ in performance, expansion and reliability characteristics.
1. USB - external USB drives are cheap and readily available. They work good for backing up small amounts of data (10-50GB). The performance of a USB drive on a Mac Pro is limited to approximately 17-18MB/sec. This translates into long backup periods when trying to copy 100GB of data to a USB device. FireWire 400, 800 and eSATA enclosures are all faster.
2. FireWire 400 - external FW400 drives are little more expensive than USB 2.0 enclosures but they provide approximately 32-38MB/sec transfer rates which is almost twice as fast as USB 2.0 on a Mac Pro. FW400 provides adequate speed for most backup situations where less than 100GB of data is in play.
3. FireWire 800 - external FW800 drives can provide 52-60MB/sec. transfer speeds. This method works well as a backup drive for a Mac Pro as the FW800 ports are built in. It also works well as a boot drive if necessary. However, when using more than one FW800 drive, speeds can be lower and many users end up resorting to PCIe expansion cards when adding more than three FW800 drives. FW800 does not provide the RAID performance that external SATA solutions can provide.
4. eSATA - external SATA hard drives can provide 57-70MB/sec. This is the fastest method for adding external storage to a Mac Pro. In addition to the Mac Pro SATA 4-bay tray system, there are also two more SATA ports on the Mac Pro motherboard (just under the front fan assembly). These ports are marked as "ODD SATA" on the motherboard. Users can install SATA cables on these ports and run them out of the back of the Mac Pro to SATA->eSATA converters like the Addonics model AASA2SAP15C. OWC also sells a kit that accomplishes this.
Ecternal 2-Port PCIe Cards
The next level of external SATA on the Mac Pro is a two port card that utilizes the SiI-3132 chip. These PCIe cards provide great individual and dual SATA hard drive performance but are limited to approx. 125MB/sec when used with a SATA PM multi-drive setup in a RAID configuration. Examples of cards in this category include:
Addonics PCIe 2-Port model ADSA3GPX1-2EM ($39.99)
http://www.amug.org/amug-web/html/amug/reviews/articles/addonics/adsa3gpx1-2em/
FirmTek SeriTek/2SE2-E ($99.95)
http://www.amug.org/amug-web/html/amug/reviews/articles/firmtek/2se2e/
External 4-Port PCIe eSATA Cards
The next step up of SATA controllers for the Mac Pro includes 4-port external eSATA cards that provide very good RAID performance and support port multiplier (SATA PM) and direct connect enclosures. These cards can support up to 20 hard drives using 4 SATA PM 5-bay enclosures and can provide 200-700MB/sec performance in RAID 0 configurations with 5-20 hard drives. Examples of Mac Pro host adapters that fall into this category include:
Addonics ADSA3GPX8-4EM ($199)
http://www.amug.org/amug-web/html/amug/reviews/articles/addonics/adsa3gpx8-4em/
DAT Optic eSATA_PCIe8 ($189)
http://www.amug.org/amug-web/html/amug/reviews/articles/datoptic/pcie8/
NORCO-4629 ($189.99)
http://www.amug.org/amug-web/html/amug/reviews/articles/norco/4629/
RocketRAID 2314 ($200)
http://www.amug.org/amug-web/html/amug/reviews/articles/highpoint/2314/
Sonnet Tempo E4P ($299
http://www.amug.org/amug-web/html/amug/reviews/articles/sonnet/mac-pro/
SATA PCIe RAID Controllers
The next step up for Mac Pro SATA host adapters is high performance RAID 5 and RAID 6 controllers that provide redundancy. Performance for this group using 8 drives in a RAID 5 configuration is 420MB/sec on average. Using RAID 6 performance is 350-380MB/sec on average. Mac Pro host adapters that fall into this category include:
Apple RAID 5 internal 4-port card ($999)
HighPoint RocketRAID 2322 RAID 5 Controller ($299)
http://www.amug.org/amug-web/html/amug/reviews/articles/enhance/e8/
Areca ARC-1221x RAID 6 SATA Controller ($680)
http://www.amug.org/amug-web/html/amug/reviews/articles/areca/1221x/
RAID 6 SAS Controllers
The next upgrade for external Mac Pro SATA/SAS hard drive users is the new SAS RAID 6 controllers. These cards provide 8-12 ports that work with either SATA hard drives or SAS drives. They also have the capability to support up to 128 devices using SAS Expanders. This new category of external storage provides almost unlimited expansion capability with a single Mac Pro PCIe host adapter. An example of this category is the bootable Areca ARC-1680x SAS RAID 6 SATA Controller ($845). AMUG is currently reviewing this card and the review should be available soon.
As you can see the Mac Pro supports a wide range of external storage options. Users simply need to decide how much storage they need and what performance level they desire. Typically, as the volume of data being maniplulated grows higher the need for higher performance also grows higher. Users working with uncompressed HD video will find large high performance RAID systems provide a great platform for video editing.
Have fun!

Problems booting from onboard SATA with PCI SATA controller installed

I have a K7N2 Delta-ILSR motherboard (BIOS v 7.8), and my Windows XP installation is on a single drive attached to the onboard Promise 378 SATA RAID controller. I have a PCI Promise TX2200 SATA RAID controller installed, currently in PCI slot 5. The OS boots normally off the onboard controller if I do not have my RAID0 array attached to the PCI controller, but I get disk boot failure messages if I have the RAID0 attached to the Promise TX2200.
I have tried putting the PCI controller in different slots to change IRQ channel routing, tried changing boot order in the BIOS, and even tried assigning specific IRQ priorities to the slot with the Promise TX2200.
My basic question is this: how do I get this motherboard to boot from the onboard controller while I have my RAID0 attached to the add-on PCI controller?

Well, Promise got back to me. They were insightful enough to tell me what I already knew and that they didn't support what I was trying to do:
Quote
Case Problem: I have an MSI K7N2 Delta-ILSR Socket A motherboard with an onboard Promise FastTrack 376 SATA RAID controller. I wish to continue booting my OS from a single SATA drive on this controller, while using a RAID0 array on my FastTrack TX2200 controller. When the TX2200 is installed and the array is attached, it is detected as C: by the motherboard BIOS and the active boot drive as D:. The TX2200 is detected during boot (after POST) first, the onboard contoller second. I have tested the TX2200 in...
Case Solution: Hi Sorry for the late reply. Are you by any chance running both the FT 376 embedded controller along with the FT TX2200 if so than you will run into bios or driver conflict when both controllers in the system. Promise only recommend and support one cards pre system. Thank you.
... and MSI
Quote
Thank you for contacting MSI Technical Support.
As onboard SATA controller and PCI controller are both promise. It exits compatibility between them. You could try the following procedures to check if they could solve the issue:
1. Please contact the PCI card vendor to ask if there is relative firmware update
2. Please disable all the onboard devices which you don't want to use in bios setup.
3. You could try different MB bios version to have a check. You could download these versions from here.
Please feel free to let us know if you still have any further issues or inquiries
So that leaves me 3... downgrading my BIOS is not worth the risk just to make this work. Looks like its time for a full migration plan so this issue becomes moot.

Has anyone tried 1 terabyte drives with Apple G5 PCI RAID card 1M9699g?

I am planning on setting up RAID 5 on one of my PPC G5 Xservers with an Apple PCI RAID card and 3 Hitachi 1 terabyte HDs. At $180 a drive and a $300 or so for a card this seems like a good setup. Has anyone tried this or have any suggestions.

It worked, for about $860 I now have a 1.8 TB xServer

Cannot boot with Perc /2 raid controller

I have just built a system with K7D + 2 2400 MP, and the system hangs when I try to boot with my Perc/2 raid controller in. I have stripped down to just the following components;
2 2400 MP
Perc 2
1GB ECC ram
Sapphire ATI Radeon 9000
When I try to boot the machine it gets as far as trying to load the Perc /2 Bios and hangs.
The Perc works fine in my old system Tyan Tiger 133 with dual 733 PIII, it also seems to boot up fine in a Tyan Tiger S2460.
Any ideas on the cause or a work around?
Thanks.

Yeah, all the firmware & bios is up to date, have stripped things down to just the motherboard, graphics card & Perc. Tried PCI graphics to elliminate any conflicts there. I have disabled all the on-board controllers too.
