Introduction to Mainframe Services

Mainframe Services from BCX give you access to the secure, stable, available servers at our Level IV and Level III data centres, and are designed for your heavy-duty, mission critical processing. The services include operating system support, system software management, and technical problem analysis. Our processes are all aligned with the best practices published by the Information Technology Infrastructure Library (ITIL), so you are assured of compliance and adhering to recommended standards. Whether your business is small, medium, large, or even a global enterprises, we can customise a service to meet your mainframe and server needs.

What are Mainframe Services?

Mainframe Services from BCX operate on our shared infrastructure, so you can access new or additional IBM z//OS – the latest IBM 64-bit operating system. This mainframe capacity is monitored and supported 24 hours a day, 365 days a year. The servers run on a Logical Partitions (LPAR) basis, where the hardware resources of the computer are virtualised as a number of separate computers, each hosting a separate operating system.

By outsourcing your mainframe capacity, you save costs because you only use the processing power your business processes need, and you can access the latest technology infrastructure on an Operating Expenditure (Opex) basis rather than a Capital Expenditure (Capex) basis. You no longer need to worry about your company’s own technology becoming obsolete or failing. Our availability levels are guaranteed at 99.9% for partners who choose standard availability, and at 99.99% when you choose high availability.
