1 Accelerating Datacenter Workloads with NVDIMMs Nigel Alvares Senior Director of Marketing Inphi Corporation November

2 Key Datacenter Trends to Tackle Software-Defined Everything Open Software & Hardware Latency-Sensitive Hyper-scale with >100k s Repurposing Rack Disaggregation Workload, Service & Application Mobility Total Cost of Ownership Reduction Power (OPEX) Replacement, maintenance & servicing (OPEX) Footprint density (CAPEX/OPEX) Infrastructure acquisition costs (CAPEX) November

3 NVDIMM-N Use Case #1: Low Write-Latency Persistent Storage Current NAND Solution Emerging NVDIMM-N Solution PCIe NVMe SLC SSD PCIe SSD Controller Optional Persistent Metadata / Write Cache x4 PCIe gen3 NVDIMM-N offering <100ns write-latency persistent storage Source: Inphi >100x Lower Write Latency Unlimited Endurance Scalable No PCIe Resources Consumed Lower Total Cost of Ownership $/Latency, $/IOPS & IOPS/W November

4 Low Write-Latency Persistent Storage Value Proposition Specifics 400GB SLC PCIe SSD 8GB NVDIMM Advantage Write Latency (us) >15 <0.1 >150x Read Latency (us) >47 <0.1 >470x Endurance Workload-dependent Unlimited Unlimited PCIe Lanes Consumed 8 0 No PCIe used Power (W) <25 <10 >2x Volume Pricing ($) >800 <250 >3x Accelerating Write-Latency Datacenter Workloads Transaction Commits, Logs & Journals November

5 NVDIMM-N Use Case #2: Write Caching TLC SSDs Current Solution Future Solution with NVDIMM-N NVMe TLC SSDs PCIe NVMe MLC SSDs PCIe SSD Controller Source: Inphi Optional Persistent Metadata / Write Cache x4 PCIe gen3 2-4 NVDIMMs as persistent coalescing write cache (32GB) >100x Lower Write Latency Higher Random Write Performance Enables Use of TLC SSDs Higher NAND-SSD Life Expectancy Larger NAND Capacity Lower Total Cost of Ownership November $/GB, $/IOPS, IOPS/W & $/IOPS/W

6 Write Caching TLC SSDs Value Proposition Specifics Current NVDIMM-N Advantage Write Latency (us) >15 <0.1 >150x NAND Type SLC / MLC MLC / TLC Cost & Capacity Protected Coalescing Cache Size (GB) <0.25GB >4GB >16x SSD Metadata Endurance Workloaddependent Unlimited Unlimited Proprietary FTL Firmware Yes No Open & SW- Defined Normalized Relative SSD Capacity 1 2 2x Volume SSD Pricing ($/GB) <1 <0.5 >2x Source: Inphi Increasing Datacenter NAND SSD Efficiencies Higher write performance, higher NAND capacity, longer life & lower CAPEX Software-defined to further optimize per server workload November

7 NVDIMM-N Use Case #3: Unified Open Software-Defined RAID Traditional RAID Solution Next Gen RAID Solution x8 PCIe gen3 NVMe SSDs SAS I/O Controller PCIe RAID Adapter x8 PCIe gen3 NVDIMM in system memory as persistent write cache SAS RoC Battery/SuperCap/Flash Backup Unit for Write Cache Source: Inphi Open & Software-Defined Workload & Service Mobility Scalable & Lowest-Latency Minimal Footprint Unified RAID for SSDs & HDDs Lower CAPEX & OPEX November

8 Unified Open Software-Defined RAID Value Proposition Specifics Traditional SW-Defined Advantage Protected Write Cache Size 1GB 2GB to 16GB 2x-16x Proprietary RAID Code Yes No Open & Proprietary Software Driver Yes No SW-Defined Service & Workload Mobility No Yes Repurpose s Single-Sourced Hardware Yes No Multi-Source Scalable RAID Performance No Yes >1x Supports HDDs & NVMe SSDs No Yes Unified Solution PCIe Slot Consumed Yes No Less Space Incremental Power (W) ~20 ~10 ~2x Volume Pricing ($) x Source: Inphi Optimizing Datacenter Storage Tiers 60% Lower Cost, 50% Lower Power & Non-Proprietary Saves >$45M CAPEX for 100ku Datacenter November

9 Multiple Datacenter Tiers & Workloads Stand to Benefit Online Transaction Processing (OLTP) SQL & NOSQL Databases In-Memory Databases Storage Persistent Write-Latency Sensitive Applications November

10 Summary NVDIMMs significantly increase datacenter efficiencies Killer use cases are persistent write-latency sensitive Enables new innovative database & storage architectures Will be mainstream component for next generation servers Software-defined architectures will greatly benefit utilizing emerging industry standard NVDIMMs November
