HARDWARE INSTALLATION
30
For Apple Mac Pro system:
•The currently Mac OS X 10.X can not directly boot up from 6Gb/s
SAS controller’s volume (We do not support the Open Firmware) on
the Power Mac G5 machine and can only use as a secondary stor-
age. All Intel based Mac Pro machines use EFI to boot (not Open
Firmware, which was used for PPC Macs) the system. Areca con-
troller has supported the EFI BIOS on its PCIe 2.0 6Gb/s SAS RAID
controller. You have other alternatively to add volume set on the
Mac Pro bootable device listing. You can follow the following pro-
cedures to add PCIe 2.0 6Gb/s SAS RAID controller on the Mac Pro
bootable device listing.
(1). Upgrade the EFI BIOS from shipping <CD-ROM>\Firmware\
Mac\ directory or from the www.areca.com.tw, if the controllers
default ship with a legacy BIOS for the PC. Please follow the Ap-
pendix A Upgrading Flash ROM Update Process to update the
legacy BIOS to EFI BIOS for Mac Pro to boot up from 6Gb/s SAS
RAID controller’s volume.
(2).Ghost (such as Carbon Copy Cloner ghost utility) the Mac OS X
10.4.x, 10.5.x or 10.6.x system disk on the Mac Pro to the Exter-
nal PCIe 2.0 6Gb/s SAS RAID controller volume set. Carbon Copy
Cloner is an archival type of back up software. You can take your
whole Mac OS X system and make a carbon copy or clone to Areca
volume set like an other hard drive.
(3). Power up the Mac Pro machine, it will take about 30 seconds
for controller firmware ready. This periodic will let the boot up
screen blank before Areca volume in the bootable device list.
2.4 SAS Cables
You can connect the end devices to each other through direct
cables or through the SAS expander/backplane connections. The
6Gb/s SAS RAID controller supports daisy-chain expansion up to 8
enclosures. The following is an example of some internal SAS/SATA
cables and an external SAS cable.
2.4.1 Internal Min SAS 4i to SATA Cable
The Min SAS 4i to SATA cables are used for connection between
the 6Gb/s SAS RAID controller internal connectors and connectors
on the SAS/SATA disk drives or SAS/SATA connector backplane.
The 6Gb/s SAS controllers has 1-6 Min SAS 4i (SFF-8087) inter
