As development dragged on, Apple eventually entered the AIM alliance with IBM and Motorola. IBM had extensive experience in object-oriented programming, notably their well-respected VisualAge Smalltalk programming system. They also had experience in microkernel design as a side-effect of their Mach based Workplace OS efforts. Pink was then spun off from Apple as a joint [...]
Processors and memory The zEnterprise System’s microprocessor is the z196 chip, a 5.2& GHz quad-core out-of-order CISC-based z/Architecture processor. The z196 can have a maximum of 24 processors giving a total of 96 cores, 80 of which will be available to run the system’s operating systems. The number of cores available in a particular model [...]

Clam AntiVirus (ClamAV) is a free, cross-platform antivirus software tool-kit capable of detecting many types of malicious software, including viruses. One of its main uses is on mail servers as a server-side email virus scanner. The application was developed for Unix and has third party versions available for AIX, BSD, HP-UX, Linux, Mac OS X, [...]

POWER6 based IBM systems have built in virtualization capabilities derived from mainframe technology. On System P, this virtualization package is referred to as PowerVM. There is an additional layer between hardware and operating systems which is called the hypervisor. IBM Power6 systems support up to 256 logical partitions on one machine, with a maximum of [...]

IBM WebSphere MQ is a family of network software products launched by IBM in March 1992.
