    Workload-optimized support


    Intel® Optane™ DC Persistent Memory delivers a new, flexible tier of memory designed specifically for data center workloads that offer an unprecedented combination of high capacity, affordability, and persistence. This technology will have a significant impact on real-world data center operations: reduction of restart times from minutes down to seconds, 1.2x virtual machine density, dramatically improved data replication with 14x lower latency and 14x higher IOPS, and greater security for persistent data built into hardware.

    Flexible storage


    Lenovo AnyBay design features a choice of drive interface type in the same drive bay: SAS drives, SATA drives, or U.2 NVMe PCIe drives. Freedom to configure some of the bays with PCIe SSDs and still use the remaining bays for capacity SAS drives provides the ability to upgrade to more PCIe SSDs in the future as needed.
