I believe this is the new enclosure he's talking about...
http://oc.adata.com.tw/1_product_detail.asp?pid=ASX1SUMAL-2

Unfortunately, there's no specs on the controller used.
When this adapter was mentioned, it made me think of the Pro Drive from Trans Intl.

It would be nice if A-Data would provide a little more information. Maybe it's just me, but the page seemed too basic, and its content not well written. :( (Perhaps the result of English being a second language)? ;)

Thanks for the link though. :)
 
If possible, can someone post up a link or describe the way to add a 5th drive to the 2009 Quad Mac Pro in place of the second superdrive?

All apple tech guys I've spoken with say I shouldn't do it, something to do with the bus for the superdrive being at a slower speed / old tech and that it's not SATA.

If you can do it, I want it to be my bootcamp drive. Will there be any performance loss (compared to if it had been booted from one of the 4 normal bays?
 
Pro Drive was made by www.stardom.com.tw not Trans international.
I believe LA computer company is selling it as well.
Saw dealmac promotion few weeks ago.
I'd only seen it on Trans International's site, and only recall seeing Pro Drive mentioned, not stardom. I shouldn't be surprised though. :rolleyes:

How dare I think they actually designed it themselves. :D :p

I can careless about data protection, speed is my major concern at this point.
I was thinking to use a product called i/o studio with a PCI-e SSD.
It will take 3 PCI-e SSD at over 1GB/s however, the capacity is small.

:)
PM chips have a max throughput of 250MB/s, so you want to keep that in mind. Especially if you were intending to use SSD's in all of them. Mechanical drives, not as much of an issue, as 125MB/s for each drive isn't too bad for SATA. (Avg, or even max STR, but very likely not Burst). SAS could be another issue, particularly if you went with some of the faster models, though most of them would be 3.5", and unable to work as you'd like. I'd have to go back and check on the Saavio 2.5" (10K) drives though. I can't recall their STR ATM.

But, the ARC-1680 series is very picky on SATA drives, and usually only runs enterprise models. They're also untested by Areca with SSD's ATM. At least what they've published. They've only tested on a SATA controller. Rather speedy though. You'd have to search the web for others who have attempted it (ARC-1680 + SSD).

Also keep in mind, that PCIe 2.0 is capable of 500MB/s per lane. So 8 lanes produces 4GB/s througput. Assuming what ever you'd use hits the PM's max throughput consistently, you'd be trying to squeeze 6GB/s of data through, so you'd certainly hit the wall before realizing the true potential of the system. You wouldn't even get the full benefit of SSD's on one of those adapters, as a single drive can approach, or even exceed 200MB/s or so.

So, if you need more than 4GB/s, you would have to use a multiple controller environment. At least two of them anyway. :p If you want to stick with the use of SSD's, you need to use One drive per bay, so a second enclosure would also be needed.

I hope this isn't too confusing.

All the drive ports are SATA in the '09's. Just get a 5.25" - 3.5" drive adapter, attach the drive, and install it. Hook up the cable. Done. Easy. :)

You just need a fine screwdriver. Shouldn't take more than 15 mins.

I installed it and the hard drive in the optical bay is as fast as the other four in Bays 1-4.
 
Thanks nanofrog! I hope it will work with no performance problems. Cheers!!
There won't be any performance difference than if it were installed in one of the sleds, as it should all be the same chip. Lower cost that way. ;) :D

If my first 4 drives are 4x1TB Raid 0, I'm assuming it won't matter what speed or size the 5th is?

Assuming it won't be part of the array and is a SATA drive, it should work just wonderfully. :)

Hello everyone, I have read through the posts on this forum numerous times about RAID and RAID configurations in my search for the perfect RAID solution for my setup and I'm looking for some more advice and experience from people who have used the various cards.

So, what I currently have is a Mac Pro 2x2.8 Ghz, 6gigs memory, with a 1 Tb drive internal and a second 1.5 Tb drive backing that up with time machine. Attached to the mac pro via an eSATA card I am running 4, 1Tb drives operating in a RAID 1+0 configuration in a Venus T5 enclosure with a Sil 4726 hardware raid card inside it.

I have a few (albeit possibly lame) gripes about this configuration. For one, the Venus Case is a loud bugger and I am not to found of large fan noises. Second I have over 6 Tb of purchased hard drive space and was looking to migrate this to a RAID 5 configuration. Currently all my drives are SATA drives and I don't think I will be affording SAS ones anytime soon.

I don't know what the performance gain is, but I've been looking at putting 2 drives in the 2nd optical bay, getting rid of the Venus and migrating to an internal storage solution. I would have a separate system disk and then I will just run the other 5 drives in a RAID 5 config. After looking at all of the card options I've sort of settled on a few that are more or less in my price range:

Rocketraid 3520, Rocketraid 4320, and the Caldigit raid card

Can anyone give me some testimonials about the relative performance of these cards? Or for that matter how much better internal raid will be relative to using the external eSATA RAID box I have now (which btw doesn't do anything other than RAIDs 0,1,10)

Thanks.

Those questions from you we gain a conclusion.All RocketRAID 3500 series & 4300 series controllers support RAID level 0,1,3,5,6,10 and JBOD. But your enclosure only support RAID level 0,1,10,
The RocketRAID 3500 series & 4300 series is really hardware RAID controllers.It have Intel IOP341(800MHz) and DDR II memory with ECC protection.it should be provide stable and dependable performance.
 
Hi guys,

Sorry to bump an old thread. I have read through and tried to find an answer but I havn't found anything definitive.

Is it possible to hardware raid 0 two ssd drives then dual boot OSX and XP/Vista off them ?

i have a early 2008 2.8 mac pro. already have the 2 ssd's. If it is possible what raid card would work? the highpoint 2320?

Cheers

It's theoretically possible from a hardware solution, but there aren't many cards that can actually boot both Windows and OS X. Then the use of SSD's complicates matters even further.

In the case of HighPoint, you have to use different firmware for Windows and OS X, so booting is a case of one or the other, not both. :(

ARC-12xx SAS and ARC-1680 SAS models will work with SSD's, and have the ability to boot Win/Linux/OS X. That's the good news.

Now the bad (unknown actually):
I don't know if the EFI version of the firmware will negate the ability to boot Windows, or if the BIOS alone (no EFI layer added) would actually boot OS X. I've sent emails, as has another member. So far, no answer. :(

Perhaps firing off an email or two would help. ;)

Sorry there's not a more definitive answer. :eek:
 
You would not believe the headaches I've been having with this. Finally spoke with the "enterprise" section of Apple support*. Bootcamp can not (apparently) be installed on my drive (even if I keep it separate from RAID) as the RAID card will still be connected in some way to it and will be detected as such. I can't disconnect the first 4 Raided drives and install OSX on the 5th and then bootcamp that and reconnect the drives. He said I might want to look at VM Ware, so now I'll look at that... :(

* This was after being pretty rudely spoken to by the 1st level person you talk to at apple support. Out right refused to transfer my call to "enterprise" (even though I had spoken with them before) because I did not have an XServe. As it turns out, Enterprise will talk to me if I have the RAID card. :mad:
 
I'm pretty sure you could run Windows in a virtual machine on your RAID, but you would get a performance drop... Maybe you could use one of the lone SATA ports? Its a headache to get them to boot Windows, from what I have heard, but its a potential solution.

What model MP do you have? And what are the details of the drive configuration?

There might be an option. ;)

This is what I'm wondering about, but would like more information.

The AHCI drivers are available, and have been installed successfully, so it can't be too hard. ;) :p

Hey, you're dealing with the dense right here! :)

It's a 2009 Mac Pro Quad. First 4 drives are Raid 0 using a Raid Card.

5th drive is connected where the 2nd superdrive would normally be. This is the drive for windows. It doesn't have to have bootcamp (if it means holding down a button at start up to over-ride OSX start up to choose the Windows drive, that's fine).

I was told VMWare Fusion wouldn't have any performance drops. I was going to write to them and ask about that. I may just try the trial version - I might just start a whole new thread if it comes to that! :eek:

The 5th drive installation should work, and boot camp isn't needed, as it's an entirely separate drive.

Download the AHCI drivers, and do a fresh installation of windows. When you get to the screen of drives and partitions, go to Load Driver, and feed it the AHCI drivers. Once it's done, then hit REFRESH*. Pick the drive, and go. :D

The only possible issue I can think of (along the lines of your conversation with Apple), is they blew it with the firmware. That is, the RAID card takes over all the SATA ports, rather than just 4.

VMWare would have a cost in resources, and overall performance would depend on what you have in the system (memory), and how loaded you run it.

Do the trial if you have to, but try the AHCI drivers first. Free can't be beat. :D :p

*Don't forget this step, otherwise you'd get an error message at the bottom of the install screen, and it won't install to the drive.;)

Hope this helps, and good luck. :)

Yes, this is the problem. Which angers me no end, as before buying this very expensive thing, I was told by one at "enterprise", 3 product specialists and 4 first level contact people all at apple support, that it was not a problem with the raid card. I only asked so many times, as it was written there saying it couldn't be done. I was told as long as it was not part of the raid set up, then all would be gravy. Now, all of a sudden, it's mud.

Any way, it's done now. It's only USD $80 for VM Fusion ware, so I'm not bothered - as long as the damn thing works.

Since the 5th drive is not part of my 4 drives in RAID, is it now wasted if I use VMWare (that is, will I have to install windows on my raid drives and not on the separate 5th?)

Either way, what sort of performance decreases can I expect? It won't be for anything professional.
 
Help! Need Advice on RAID Setup

Hi

I have an '09 Mac Pro with Apple RAID and 4 1 TB internal drives. I am trying to make up my mind how I am going to configure the filesystem and I am considering the four options below. I have a sense of the tradeoff in terms of performance, space and security but I would appreciate any thoughts or experience with this. Also, any advice on a reasonable size for a startup volume (30GB?)?

1.) Startup and Data Volume on JBOD, 2 Drives, Time Machine Volume on the other two drives to back up the Data Volume

2.) RAID 5 across three Drives, 1 Drive Hot-Swap Spare

3.) RAID 5 across four drives

4.) Mirroring across pairs of drives.

Forgive me, but I'm a little confused. Did you try the AHCI drivers and installation method I described, and it wouldn't work? Or something else happened?

Any way, it's done now. It's only USD $80 for VM Fusion ware, so I'm not bothered - as long as the damn thing works.
Again, it shouldn't be a problem...:p Seriously, it's software that's been known to function on Macs rather well, so you should be good.
Since the 5th drive is not part of my 4 drives in RAID, is it now wasted if I use VMWare (that is, will I have to install windows on my raid drives and not on the separate 5th?)
My experience with VMWare was rather limited on a Mac, as I sent it back in the return period. But IIRC, you can specify where to put it (windows). :)

Either way, what sort of performance decreases can I expect? It won't be for anything professional.
Too hard to say for me really. I've no idea of what you're doing, or how you plan to allocate resources.

But so long as you don't peg the limits of the hardware (one instance rather than multiple VM's,...), performance would be acceptable.

Without details, it's sort of a wild guess, but you'd want to look into #3, or even consider going for RAID 10 (1+0). 10 is a little safer (additional redundancy), but is a little slower, and only offeres you half the capacity of the drives used. But with any RAID or even single HDD, you do need a backup. For me, the need is stressed even more when RAID is involved, as the data is too important to lose.

The reasoning is this; I'm assuming you'll be in front of the system daily, and catch any warning off the array really quickly. So this helps mitigate the need for a Hot Spare. You'd get better performance out of the 5 array, than #1.

For backup, you might want to look into suffing up to 4*2.5" drives in the empty optical bay connected to a SATA card, or going external. The easiest, and least expensive might be to use an eSATA card, and say a 4 bay enclosure (eSATA connectors).

Hope this helps. :)

no, I've been away from the computer a few days and will maybe give this a go when I get back and if i can get a few hours to myself. Will update when I can. Cheers again Nanofrog! :)
