IBM System z9 Business Class (z9 BC): A mainframe specifically designed to meet the needs of small to medium enterprises

The IBM System z9™ Business Class (z9 BC) takes advantage of the innovation of the System z9 platform and is designed to bring value to a wider audience, both midrange and small enterprise businesses. The z9 BC offers a low cost of entry, granular growth, flexible configurations, subcapacity pricing and On/Off Capacity on Demand to meet growing and changing demands for traditional and new workloads. And the z9 BC can participate in IBM’s Parallel Sysplex® technology, which can give you the flexibility to solve business issues such as rapid response to business needs change, ensuring continuous availability of IT assets and reducing your overall cost of computing.

On the z9 BC, subcapacity options are offered on 1-way to 4-way servers. Having the ability to offer just a portion of the full capacity gives you greater flexibility. The z9 BC is available in two models with 73 capacity settings so you can choose just the right size. The Model R07, aimed at smaller enterprises, has a smaller I/O configuration and lower entry point where large amounts of resources are not the driving factor, but always a quick upgrade away when needed, either temporary or permanent. The Model S07 is aimed at medium-sized businesses that need to have more available I/O or more capacity, as well as upgrades to the IBM System z9 Enterprise Class (z9 EC). For ease of installation, the z9 BC can be installed in either a raised or non-raised floor environment. Today, more than ever, z9 BC means there is a System z9 for everyone.

The z9 BC is able to manage numerous operating systems on a single server, including z/OS®, z/OS.e, z/VM®, z/VSE™, z/TPF, TPF, and Linux® for System z9 (31-bit and 64-bit distributions). The operating systems are designed to support existing application investments without anticipated change to help realize the benefits of the z9 BC.

IBM provides world-class mainframe technology to help today’s enterprises respond to business conditions quickly and with flexibility. From automation to advanced virtualization technologies and open industry standards such as SOA, IBM mainframes teamed with IBM’s storage products help deliver competitive advantages.
