Storage Technologies / Re: Is PCI card based hosted SCSI RAID a thing for MacOS?

In the photo, two machine, one (MDD FW800) is BOOT in OS-X with 4 SCSI HDD 15k RAID 0 (Apple raid) ATTO UL4D

Another machine (MDD 2003) for music production has an internal two HDD 15k RAID 0 (ATTO Express Raid) ATTO UL3D


Who is well versed in the topic knows that the SCSI controller should be in the last PCI slot, when I took a photo, I did experiments with the system boot speed in different slots, and stability

I would like to put a striped RAID 0 SCSI array into my PowerMac G4 Gigabyte. I would like to have it recognized and bootable into both MacOS 9 and OS X. Is this something that can be done on the Mac?

Not sure if hardware hosted SCSI RAID is a thing on a Mac. I know from my limited experience in the Windows/Linux world, the PCI card would handle the hosting with its own accessible BIOS settings and then Windows sees it as a single drive.

I currently have an ATTO ExpressPCI PSC PCI SCSI card w/ internal 68-pin and 50-pin headers, and an external 68-pin(?) connector. And I want to connect two 18gb Quantum Atlas 10,000 RPM server drives in a RAID 0 (striped) configuration. I would use this drive-array to boot into MacOS 9.2 and OS X 10.4 Tiger. The RAID array serves no other purpose than for me to feel cool when the jet-engine decibel SCSI drives spin-up and perform their ADHD accessing. This is a for a retro-computing nostalgia project. It doesn't serve any critical functions or need to have server level performance.

My SCSI knowledge ends around the PowerPC 603/604 era. Please educate me if you've got SCSI knowledge.

There are absolutely no problems with SCSI on OS9, although your adapter is not very suitable for the full impact of this technology, you need a ATTO UL3D card and also if you want to create a raid array you can do it from OS-X using the Atto utility and extensions for detecting raid arrays "OS9 enabler"

New discovery--just installed 9.2.2 and a few apps on a TeamForce 1TB SSD connected to the Sonnet Tempo PCI SATA card on my 2002 G4 Dual 1.0 GHz.  Drive Setup saw it, partitioned it, and installed the OS.

OS9 sees it as SCSI Bus 0, just so you are aware when you have other SCSI devices. . . . .

Tempo Serial ATA (2x) or Tempo Serial ATA x4?

pricey 250-800 eur for that card alone these days

I was running with 256kb buffer per track and 3ms latency on VST/32. Having to move up the latency on Logic 6 but not sure how to achieve the same buffering I had in Cubase.
65
do you have different track buffer sizes in cubase and logic? there is a difference, but it should not be >5:1.

what stresses disks the most is reading and writing at the same time (plus reading might be reading a lot of small files), otherwise recording 32 tracks is not a problem at all, and RME or motu are working systems for that kind of thing.

All,

I have decided to use Mac OS9 as my main DAW setup for my studio. For the longest time I have mainly worked with 2 channel at a time recording and got by great. I am planning to run at least 34 channels in and 34 channels out using a RME Digiface and Multiface. A Mackie 32-8 will be feeding the G4 a variety of inputs from my setup as needed.

I have 2 OWC 120GB SSDs on the ATA/100 bus, one for OS9 booting and the other for recording. I recently acquired a Seritek 1SE2 and external enclosure running a 480GB Inland SSD. Running Norton System Info, my overall disk performance was less than the SSDs on the ATA bus. On the PCI bus I am running 2x RME HDSP PCI cards, Seritek 1SE2, Adaptec 2906 for Sampler management.

Logic 5/6 seem to use a lot of Disk I/O on a few channels while I can run up to 32 mono channel projects on Cubase VST with 20% disk usage. Any tips on getting Logic 5/6 to match the performance of VST? I like VST but projects made on it don’t transfer over as well to newer versions in my experience.

First issue… I guess somebody around here is gonna havta fix this since it's becoming a regular thing.

So I rebooted into the MacOS9Lives CD to try to do DieHard's suggestion in the Disk Setup. It did not recognize the whole harddrive (only ~130GB), and did not offer me the option to install the necessary driver:
https://postimg.cc/SXMSNq6x

I am so sorry, apparently the "boot" part of out install has the older drive setup 1.92 (even though our 9.22 image has the newer 2.1 version), so don't use the one on the root of the CD when you boot, instead double click our drive image and navigate to the drive setup 2.1, that one will see the whole hard drive past 128GB...

Second issue:
I'm assuming you mean you were able to boot from the FW HD before it was imaged… when it was a "real" drive.
You can't boot from an imaged drive and System because the System has to boot in order to mount the image to find the System you're trying to boot from… Yup, it's a conundrum.

You should use the Panther Restore to setup and partition the 1TB drive, install OSX, install OS9 and bless the OS9 System folder then birdies should sing, flowers should bloom and all will be well………maybe

Alright so, another conundrum here. I've gotta G4 "Lampshade" iMac here... It's the 800 mHz 17" FP right? It WAS capable of booting into a partition with OS 9.2.2 until recently. It's like this, I can boot from the OS9Lives 9.2.2 Universal CD versions that I have burned but I cannot boot from an imaged FW HD that I had also been successfully using previously too. This is also true of OS X versions that I have tried with the exception of already installed OS X versions. I did find however that I can install from the OS9Lives CD and I can initialize the system disk, however that wipes the current contents for the 1 TB SSD I have in there and only formats as one 135 GB partition and it leaves no free space to use for any other partitions when I examine it booted from FW into an image of OS X. I even tried the actual Panther Restore Disks for this system from the Macintosh Repository and yeah it "seems" to successfully install, but when booting, I get the flashing floppy and System Folder for OS 9, that drops away and it chimes again when I reboot from OS X and set it as the OS 9 start up disk. The Boot Picker no longer ever shows an OS 9 volume like it used to. What could be going on here? Shall I futz around with an Open Firmware hack as a workaround?

IIRC the composer confirmed in an email that he used bitheadz products for some other things as well. Notably Unity DS-1, Retro AS-1 and Voodoo have stuff in it. although not all of DS-1's factory library is archived... anyone happen to have the original disc for it?
