Which of the following is used to consolidate host channels on an IBM z14?

Question

Options

• ACFSIZER tool
• BFICON Aggregation analysis
• CFit for Purpose study
• DzBNA tool

• A
  3% (1)
• C
  3% (1)
• D
  94% (32)

Explanation

zBNA (z Business Network Analyzer) is the IBM-provided tool specifically designed to analyze I/O configurations and identify opportunities to consolidate host channels on IBM z14 systems - it evaluates channel utilization data and recommends how to reduce physical channel counts while maintaining throughput.

CFSIZER (A) is a sizing tool for Coupling Facility structures in a Parallel Sysplex environment, not for channel management. FICON Aggregation analysis (B) sounds plausible because FICON Express is the channel technology used on z14, but it is not the name of a specific IBM consolidation tool. Fit for Purpose study (C) is an IBM consulting engagement that assesses overall infrastructure alignment with business goals - too broad and advisory in nature to drive channel consolidation decisions.

Memory tip: Think "zBNA = z Bandwidth Network Analyzer brings channels together" - the word consolidate links to bringing things together, and zBNA is the tool that tells you how many channels you can safely combine.
