IBM zEnterprise System

^* The energy consumption efficiency is the value of the power consumption measured in accordance with the measuring method specified by the Japan energy saving law divided by the Composite Theoretical Performance specified by the energy saving law.

¹ If ordering a zAAP or a zIIP, one or more general purpose processor (CP) per the specialty engine is required. One CP can satisfy the requirement for either or both of the specialty engines.

² No IFL is required unless ordering an IFL only server—model capacity identifier 700. If you order a 700 no CP is orderable.

³ Assuming feature HCA3-O. Maximum of 32 1x IFB ports on M15; Maximum of 16 12x IFB ports on M15

⁴ ISC-3 Peer mode only

⁵ Excludes the standard fixed size of 16 GB HSA

⁶ z/OS V 1.10 is required to support an ensemble.

⁷ On November 1, 2011, IBM Smart Analytics Optimizer was withdrawn from marketing for new build and MES zBX. It has been replaced with IBM DB2 Analytics Accelerator for z/OS (IDAA), a new workload optimized, appliance add-on that attaches to the zEnterprise System.

⁸ The blades for BladeCenter PS701 Express blade, BladeCenter HX5 blade and DataPower XI50z can be shared in the same BladeCenter chassis—note that DataPower XI50z blades are "doublewide" and use two slots. They can be mixed in the same zBX with IBM Smart Analytics Optimizer blades—but not in the same BladeCenter Chassis. Total zBX capacity cannot exceed 112 total blades.
