Subsystems

Hostel or hotel?



Share |

One of the great rites of passage for students is the grand tour of Europe. Hopping between cities with a Eurorail pass, they visit historic capitals by day and stay at economy hostels by night. The hostels all have dormitories with bunk beds and shared bathrooms. After all, sharing facilities, meeting new friends and experiencing different cultures is all part of the experience. Later, however, as people travel for business, they choose hotels because they prefer business services and want separation from crowds as well as dedicated space to sleep, work and relax. They book a room or suite to match their specific business needs.

IBM i subsystems are the business hotel rooms of the operating system world. Within one image, subsystems isolate database and application workloads, matching resources and priorities to business service goals. They are, very simply, designed for business.

More like hostels, x86 operating systems are not designed to isolate workloads; if one process fails, it may affect another. To avoid conflicts, applications and databases are typically run in separate virtual machines or servers—they’re moved to a different hostel.

Subsystems are a key reason why businesses running IBM i have fewer servers to manage and report a lower total cost of ownership than x86 servers. Hostels have their place, but hotels are designed for business.
