12 First Question Amit, what does Plexistor do? 12

13 PM Adoption Amit Golander, PhD Plexistor, CTO

14 Where does Plexistor fit in? Any Application Enterprise-grade platform to make PM trivially consumable by applications Plexistor SDM Linux Server & Bios PM & 3D Flash 14

15 From Promise to Delivery in 3-4 years PM Summit Focus Plexistor Status Deliver Promise Jan Jan Jan Jan Jan What are the problems? The Future of Computing The convergence of Memory and Storage Realizing the Benefits of the Convergence The Status of the Convergence Delivering on the Convergence Concept Alpha Public Beta GA Prototype AutoTiering DAX, Stability Clones, PMoF Use cases 15

16 State of the Nation (Jan 2017) Legacy and PM aware SDM v2.1 as SW or pre-installed SKUs (partners) Kernel 4.4+ Ubuntu RHEL 7.3 HPE Proliant Gen9 Supermicro X10 16GB NVDIMM-N JEDEC FW Any Application Plexistor SDM Linux Server & Bios PM & 3D Flash 16

17 The Plexistor SDM Solution Installed on top of Linux w/ NVDIMM driver Runs any application on bare metal, container or virtualization Enterprise-grade features: Storage and Memory semantics concurrently Auto-tiering between NVDIMMs and Flash SSDs Light-weight Clones Mirroring to PMoF NUMA optimized, Dashboarding, Proactive support, Forward migration 17

18 Performance PM & SDM delivers, provides data services and is production ready 18

19 PMoF Sneak Peek SDM v3.0 Application-agnostic PMoF is around the corner 19

20 Example: Oracle Database for OLTP Baseline Exadata X6-2 Full Rack Running Oracle RAC 12C Plexistor Solution 1 HPE 2x2699 server Running Oracle 12C Max IOPS 5.6M Throughput 21GB Latency 250us #Cores 72 License cost $2.1M Swiss Federal Government Max IOPS 6.5M Throughput 30GB Latency 2us #Cores 24 License cost $540K Run the exact same application Faster and at 75% lower cost 20
