* 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.
† No IFL is required unless ordering an IFL only server—model capacity identifier 400. If you order a 400 no CP is orderable.
‡ ISC-3 Peer mode only
§ Assuming feature HCA3-O. Maximum of 32 1x IFB ports on M15; Maximum of 16 12x IFB ports on M15
** Provides the minimum physical memory required to hold base purchase memory plus 32 GB HSA
†† All supported releases of Windows may not be available from Microsoft but continue to be available from IBM and other resellers.
‡‡ 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. Total zBX capacity cannot exceed 112 total blades.
