Actual speeds vary and are oftenless than the possible maximum.When referring to processor storage, real and virtual storage, or channel volume,KB stands for 1024 bytes, MB stands for 1,048,576 bytes, and GB stands for1,073,741,824 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 can 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 that are available from IBM.Maximum memory might require replacement of the standard memory with anoptional memory module.Each solid-state memory cell has an intrinsic, finite number of write cycles that thecell can incur. Therefore, a solid-state device has a maximum number of writecycles that it can be subjected to, expressed as “total bytes written” (TBW). Adevice that has exceeded this limit might fail to respond to system-generatedcommands or might be incapable of being written to. IBM is not responsible forreplacement of a device that has exceeded its maximum guaranteed number ofprogram/erase cycles, as documented in the Official Published Specifications for thedevice.IBM makes no representation or warranties regarding non-IBM products andservices that are ServerProven ®, including but not limited to the implied warrantiesof merchantability and fitness for a particular purpose.
