“Digital UNIX continues to dominate the 64-bit arena, leaving HP-UX and IRIX to contest the second position, followed closely by AIX. Solaris and NT trail significantly behind. AIX offers good backwards compatibility for 32-bit applications and a few other compatibility bonuses. However, IBM has lagged behind its competitors in providing 64-bit hardware, shipping its first 64-bit server only now.” —D.H. Brown Associates

Kernel: “real-time support, dynamic kernel extensions, SMP (up to 12-CPUs), 64-bit ready” —Chun Fong

POSIX: certified

• Open Group UNIX 98 certified
• LDAP 1.1
• TCPIP V6
• C2 security
• IEEE POSIX 1003-1996 (.1c) threads
• British Standard Institution ISO 9001 certified
• ICSA’s Virtual Private Network (VPN) Certified
• ITSEC’s E3/F-C2 security level certified

Periféricos: “Standard Peripherals: PCI slots, SCSI-2, PS/2 keyboard and mouse, Ethernet. You can use SVGA monitors. SSA is optional.” —Chun Fong

• file systems can read/write/format: JFS, NFS (Network File System), AutoFS, CacheFS
• file systems read only: ISO 9660
• file systems can read/write/format through third party or optional software: DFS (OSF DCE’s Distributed file system), AFS (Transarc’s file system)

“As UNIX evolves into a 64-bit operating system, AIX 4.3 and Digital UNIX 4.0d share the lead for delivering commercial UNIX functions. AIX 4.3 extends its already dominant position in system management with a cutting-edge, Web-based system manager, which has the dual advantage of making management tools more accessible to mainstream users via a Windows 95-like interface while also simplifying remote management thanks to its Java implementation. Following IBM’s massive investment in fulfilling network computing requirements, AIX 4.3 also seizes the lead for delivering Internet/intranet features.” —D.H. Brown Associates
