Actual speeds vary and are often lessthan the maximum possible.When referring to processor storage, real and virtual storage, or channel volume,KB stands for approximately 1000 bytes, MB stands for approximately 1 000 000bytes, and GB stands for approximately 1 000 000 000 bytes.When referring to hard disk drive capacity or communications volume, MB standsfor 1 000 000 bytes, and GB stands for 1 000 000 000 bytes. Total user-accessiblecapacity may vary depending on operating environments.Maximum internal hard disk drive capacities assume the replacement of anystandard hard disk drives and population of all hard disk drive bays with the largestcurrently supported drives available from IBM.Maximum memory may require replacement of the standard memory with anoptional memory module.52 IBM System x3250 Types 4364 and 4365: Installation Guide
