1 6TB maximum memory vs. 2TB or less for previous-generation competitive 4-socket servers.
2 x3850 X6 without eXFlash DIMMs can support up to 25.6TB of Flash storage using 16 x eXFlash 1.8” 400GB SSDs and 8 x 2.4TB MLC Duo Adapters. An x3850 X6 with eXFlash DIMMs can support up to an additional 12.8TB Flash storage leveraging 32 x 400GB eXFlash DIMMs for a total of 38.4TB) of flash storage in the server.
3 Laboratory testing shows eXFlash DIMMs can deliver 3 times lower latency (<5 microsecond) than PCIe based flash (15-19us).
4 When a newer generation of processor and memory technology becomes available, Compute Books can be replaced with newer ones. (All Compute Books must use matching technology.)
Lenovo acquires IBM x86 systems
These IBM x86 products are now products of Lenovo in the U.S. and other countries. IBM will host x86-related content on ibm.com until migrated to Lenovo. During the transition, please interpret references to IBM in relation to transitioned products as Lenovo.
