NetWare for PowerPC Apple partnered with Novell in the mid 1990s to port NetWare to the PowerPC. The jointly funded port was designed to be much easier to configure than NetWare for x86. It was intended to run on an Apple-designed server called Shiner. Although the port was more or less completed the project was killed before it ever shipped. Shiner would lead to the Apple Network Server which ran AIX. . AIX for PowerPC A few years later in 1996 Apple had a short-lived product called Apple Network Server. The PowerPC-based server had hardware features such as the following. Processor resident on a daughterboard for easy upgradeability An easy-to-replace logic board Up to 1MB of L2 cache Up to 512MB of parity RAM A 4MB ROM and an 8KB NVRAM Multiple hot-swappable and RAID-capable drive bays for a total approximate disk capacity of 340GB Hot-swappable power supplies and fans Provisions for adding several SCSI devices and PCI cards An external LCD display for system diagnostics and status messages Several physical security features 82 Chapter 1 A Technical History of Apple s Operating Systems The Network Server came with the AIXfor Apple Network Servers operating system which was based on IBM s AIX. The server did not support Mac OS. With AIX Apple had an advanced operating system with features such as the following. Memory protection Preemptive multitasking Multithreading Support for various networking protocols including AppleTalk and AppleTalk services RAID Journal File System JFS Logical Volume Manager LVM which supported multiple file systems up to 256GB in size and could handle files up to 2GB in size The user could work with the command-line interface or could have one of the AlXwindows or Common Desktop Environment CDE graphical interfaces. The operating system included several .
