S.I. TECHNOLOGIES offers Unix-expertise in different flavors
Solaris
Solaris was developed by Sun Microsystems. It is certified against the Single Unix Specification as a version of Unix, and although historically a closed-source project, has since been open-sourced by Sun Microsystems. It is now one of the largest open-source projects in the community, and it continues to grow in features, members, and applications.
HP-UX
Hewlett-Packard's HP-UX delivers features that enhance leadership in flexible capacity, secured availability and simplified management. Its OS performance turbocharges your applications. The Open Group certifies that HP-UX 11i conforms to the UNIX 03 standard.
AIX
AIX (Advanced Interactive eXecutive) is a proprietary operating system developed by IBM based on UNIX System V. The scalable AIX 5L supports up to 64 central processing units and two terabytes (TB) of random access memory. The JFS2 file system—first introduced by IBM as part of AIX—supports computer files and partitions up to 16 TB in size.
Linux
Linux is a Unix-like computer operating system that is one of the most prominent examples of free software and open source development. Its underlying source code can be modified, used and redistributed by anyone freely.
Predominantly known for its use in servers, Linux has gained the support of corporations such as IBM, Sun Microsystems, Hewlett-Packard, and Novell.
Linux is used as an operating system for a wide variety of computer hardware, including desktop computers, supercomputers and embedded devices such as cellphones and routers.
