MacPro Raid Card single drive size limit

OK this is a follow up to a previous question about the upper size limit of a single HD that the Macpro Raid card can address.
It was pointed out to me that "The Apple RAID card cannot address more than 2.2TB of a drive" by Mr. Grant Bennet-Alder. So I am assuming that a 2TB SAS will work.
I plan to RMA the 4TB drive (that was not recognised), so my question is will this drive work instead?
Seagate Constellation ES 2TB 6GB/S SAS 7200RPM 3.5in (ST2000NM0001) Hard Drive - setup as JBOD.
It's not that I don't believe what Grant has said, it's just that I don't want to RMA this drive as well, using the old wood working philosophy of 'measure twice, cut once.'
And I spent 2 hr looking for this info on Apple's support site without any luck.

If a Disk Fails If a RAID set or volume becomes degraded because a disk has failed, you can use RAID Utility to identify the disk that needs to be replaced.
Note: If your RAID setup includes a spare drive, it is automatically incorporated into the RAID set, and the set switches from degraded to good as soon as the recovery process finishes. If there is no spare, the set will remain degraded until you replace the failed drive, and if a second drive fails before you replace the first, you could lose data.
To replace a failed disk:
1 Open RAID Utility, select the RAID set or volume that is displaying a problem status indicator, and look for a drive bay with a red status indicator. The bay numbers in RAID Utility correspond to the numbered drive bays in your Mac Pro or Xserve.
2 Replace the bad drive module.
3 Use the Make Spare command to set up the new drive as a global spare. If no spare was available when the original drive failed, the RAID card uses the new spare immediately to rebuild the affected RAID set and volumes. If a spare was available at the time of the failure, it is already incorporated into the affected RAID set, and the new spare remains available until it is needed.

MacPro RAID card - best drives?

Hey, anybody have any experience they'd like to share on a good set of drives to go with the Apple RAID card? I want to get 4 and I'm looking for maximum speed, but I can't break the bank, so no Raptors.
cheers,

Well, save your $$ and just DON'T! get the Apple RAID card, then you could afford some decent drives.
600GB 10K VRs $279 x 2
OWC SSD 100GB x 2
As for what drives, bare in mind -
If you read the Apple Support Mac Pro link to RAID card FAQ:
Question: *Which drives does Apple support for the Mac Pro RAID Card and the Xserve RAID Card?*
Answer: Only Apple SATA drives and Promise 450GB SAS Drive modules sold through the Apple Store are supported for use with the Mac Pro RAID Card (Early 2009) and the Xserve RAID Card (Early 2009). Apple 300GB SAS Drive modules are supported with the Mac Pro RAID Card (Late 2007) and Xserve RAID Card (Early 2007). Drives must be either all Serial ATA (SATA) or all Serial Attached SCSI (SAS) drives. SSD drive modules are not recommended for the Apple RAID Card because these drives use their own on-disk cache and cannot take advantage of the protection provided by the battery-backed cache on the RAID card.

People do try and use retail SATA drives, with mixed results. I have never seen anyone mix SAS and SATA.

External Drive Size Limit

Hello,
I've been using Time Machine with a 300GB external hard drive. It filled up, so I bought a 750GB FireWire drive (Maxtor OneTouch 4 Plus).
The disappointment was that I cannot format it in Disk Utility (Mac OS Extended (Journaled) format). Disk Utility says something like: "Low Level Format Error" after pressing "Erase..." in the Erase tab.
I was able to create two partitions: 626GB and 71GB. But, the second partition isn't useful for Time Machine. Is this 626GB the limit of the Mac OS file structure? Is there any way to use more than 626GB for Time Machine?
Gerd

I'm looking for confirmation that someone has a non-RAID, single partition, Mac OS Extended (Journaled) file format drive that's 750GB or 1TB.
:: Waves hand :: Over here!
I have several, in fact. This drive size is absolutely not the limiting factor.
In general, disk erase problems are usually disk-level problems.
I'd like to know what the non-RAID, single partition size limit is for the Mac OS Extended (Journaled) file format.
Currently 1TB, but that's because that's the largest single drive available, not because the format itself is limited to 1TB.
Extended (Journaled) partitions can be as large as 8 exabytes (that's about 8 million terabytes), so 1TB is not going to stress the system at all.

Is there a hard drive size limit for G5 imacs?

I recently added a 1.5 TB firewire drive to my father's iMac. Since then the system has been hanging frequently and I have not been able to restart the machine remotely using either Timbuktu or ssh sudo reboot.
Is this drive too big for leopard to handle on the G5?

Is there a hard drive size limit that can be hooked to the airport extreme

I am trying to connect a 2TB HDD to my Airport Extreme but it doesn't see it. It is a Mac formatted drive I have been using as my backup drive but want to put it on the Airport Extreme to share some other stuff that's on it. When I hook in a 500GB drive it works just fine.
There are no windows machines (god forbid) that will share it, all Mac.
Thanks!

MacPro Raid Card w/ SAS Drives is battery required?

We have a MacPro (early 2008) dual 2.8 Quad with Mac Raid Card and 4 300g SAS drives. The battery became an issue early on it was always showing low on start-ups. Now it shows failed. I am now running system with 3 drives striped raid 0. Is the battery required to be replaced? I like this system for the speed it gives us on short HD, using my original media as the back-up. I am a little out of my league with the SAS drives so any opperation tips would be a plus! Thanx in advance....

The RAID card allows for the use of SAS drives or for the use of RAID 5 (which requires checksum calculation on writes and for data re-creation after a failure).
The battery assures that the data will be held in the RAID card's RAM until it can be written to the drives, even if a power failure occurs just after the data are written to the card (but before they are re-written to the drives).
Not using that feature? You don't need the battery.
Not using RAID 5 or SAS drives? You don't need the Apple RAID card. Disk Utility can set up Striped or Mirrored RAID sets.

MacPro RAID card not initiating recovery after defective drive replaced

One of my artists is using an Early 2009 Mac Pro on 10.9.5 (13F1077). On Saturday morning, while he was not in the office, Drive 1 warned that SMART was reporting early signs of failure. The RAID card degraded the RAID set. I replaced Drive 1 and marked it as a global spare; but recovery is not initiating. I have, subsequent to installing the drive and marking it as a global spare, rebooted the Mac Pro; but the RAID Utility is not showing any Tasks running, and especially nothing about rebuilding the RAID set. As of now, the RAID set and RAID volume are not available. It appears that I can either try to preserve the data on the drives, or I can attempt to manually rebuild the RAID set; but not both. Unfortunately, the artist had all of his projects on the RAID and had not backed them up to servers at the time of the failure.

If a Disk Fails If a RAID set or volume becomes degraded because a disk has failed, you can use RAID Utility to identify the disk that needs to be replaced.
Note: If your RAID setup includes a spare drive, it is automatically incorporated into the RAID set, and the set switches from degraded to good as soon as the recovery process finishes. If there is no spare, the set will remain degraded until you replace the failed drive, and if a second drive fails before you replace the first, you could lose data.

Quicksilver scsi drive size limit ?

Hello all.
The original 37gig SCSI drive on my Quicksilver (NOT mirror door) is beginning to sing a sad song so I am looking into replacement.
I know there is a 128gig size limit for ATA drives in this model but is there any size limit for internal SCSI ????
I have already added a 120gig ATA with my original 80gig ATA so I think I'm pretty well maxed out (heat and power wise) on internal ATA drives.
Due to the cost of SCSI drives I'm thinking what I may do is buy an external LARGE firewire dive, transfer the contents of my internal SCSI drive to that firewire drive and then just use the SCSI drive as a dedicated "video capture" drive until it finally dies.
So, besides the original question about SCSI drive size limits does anyone have anythoughts on going external firewire vs. additional internal drives?
Thanks.

Hello! If speed is an issue get a sata Raptor drive (most 36 or 80 gigs). The access time is as fast as a 10,000 rpm scsi drive. Just add a sata card to use the sata drive. Tom

Erase old error messages of MacPro RAID Card?

Hi there.
I changed HDDs in my MacPro, they were configured as an RAID 1 using Apples RAID Card.
After mirroring the old System to the new (RAID 5) System, there are several error messages left in RAID Utility - where are they located to delete them?
Maybe I was wrong simply to change the HDDs, but is there a chance to solve that issue?
Thanks in advance.

Get someone on ebay to buy your over priced under supported card.
Or accept the 2.2TB (some people only got the 800GB portion which needs to be set as free space).
Or use 2TB drives.
Or external RAID but watch out for ATTO SAS and their Java program that doesn't work.
WD RED 3TB drives are designed for NAS RAID, firmware to support RAID TLER.
SoftRAID 4 makes a nice software RAID and does a good mirror with three drives in stripe reads (mirror only begins with minimum of two).
NO Apple just won't can't whatever offer a card and firmware. Odd with all their GUID support for large volumes isn't it.
It is designed for smaller SAS drives in today's world. And for RAID5 on 3TB and issues with battery... POS throw it up on ebay!

USB Hard Drive Size Limit

Is there a TB size limit for external HDDs connected via USB on a mac?
I have both a 3 TB and 4TB external 3.5" drive that will not mount via USB. They are currently connecting via a hdd dock (with USB 3, FW, and ESATA ports) to a 2009 Mac Pro running latest version of Yosemite. They will however mount via esata, the internal sata drive bay and FireWire. Also, it seems that smaller sized HDDs ~1TB and under will mount (I haven't tried 2TB since I don't have one available, but I suspect it will work).
Note that this is not exclusive to the 2009 Mac Pro as I have tried it on the newest Mac Pro Cylinder and got the same results via USB 3. I found this was an issue in Mavericks too and tried Snow Leopard on an old iMac with the same result.
When I inspect the disk in disk utility via USB disk utility reads that the HDD is MBR when I know that it is GPT (GUID) and all the other connections read this correctly.
Any insight into this?
Thanks.

One of the drives is (connected via USB3... )
Drives are drives, and SATA. Know what you meant.
Some people have taken their internal drives, put in a USB device, formats properly, then return to use internally where the full capacity is seen and not an issue.
Why is DU treating internal drives on the SATA controller used an issue? really strange - and bad. But then Apple Pro RAID controller also limited drives to 2.2TB and would format as 800GB otherwise if they were larger.
Still points to the drive case.
And in using 3rd party PCIe USB3 controller, that could play a role as well.

Apple RAID Card, All Drives RAID?

For those of you who have the Apple RAID card, I was wondering if all the drives are configured into one RAID set? Or can you have say a single boot drive, a third data drive and then have the remaining two drives set up as a RAID 0?

I was interested in using the RAID card for 2 drives only, for storing captured video.
I don't want to use the RAID for my boot/data drive.

RAID Card or Drive Failure ? ?

My Mac Pro with Apple RAID card will not boot to external FW800 or original install DVD if drives 2, 3, 4 are installed at the same time in any of the bays (i.e. gray screen, no apple, nothing).
If I remove or replace any one, or more, or remove all of drives 2, 3, 4 Mac Pro will boot to anything with an OS on it via Opt. key. I'm thinking if any one of drives 2, 3, 4 were bad and drawing too much power the same problem would present when drive 1 (J+ w/ OS) is substituted for any one of 2, 3, 4.
Replaced battery on RAID card no effect on problem. Passed Hardware Diagnostic on original Installer DVD. I'm thinking this has to be a RAID card issue. Do they go bad? Any opinions / suggestions would be greatly appreciated - Thank you,
John

Software RAID?
No, I have an the Apple RAID card that came with the Mac Pro, factory installed. RAID set was created with Apple RAID Utility. About testing, D-Genius only does a random/sustained read/write. I like the looks of intech's suite, but just spent $$ on new, replacement SAS drive, they're still not cheap, even with the advent of SSDs. Anyway, I had saved a profile of the DG benchtest on the previous RAID volume. When I ran the new disk the results very closely parallel the previous profile very closely. Odd thing is that I'm not sure it was a hardware problem (bad disk). Once I introduced the new disk into the mix, I was able to also re-introduce the old suspected bad disk and it worked. Maybe a RAID fluke??? Maybe the disk was intermittently failing causing the RAID set to fall over? Maybe I'm just cursed....

Apple Raid Card, multiple drives and volumes

Hallo,
my xserve (early-2008) has an Apple Raid Card and two 300GB SAS-drives installed (mirroring).
Is it possible to install a third disk (300GB SAS) and to use it as a separate Volume ?
Disk 1 (300GB SAS) - Apple Raid Card mirroring: Volume 1 (300GB)
Disk 2 (300GB SAS) - Apple Raid Card mirroring: Volume 1 (300GB)
Disk 3 (300GB SAS) - Volume 2 (300GB)
How do I have to set this up using Apple Raid Utility ?
Thanks for your help !

Is it possible to install a third disk (300GB SAS) and to use it as a separate Volume ?
Yes. Of course.
How do I have to set this up using Apple Raid Utility ?
No. A third drive should just appear on the desktop. You only need RAID utility if you want to add that drive to an array, which doesn't sound like the case here.
