1、SFF TA-1034Pluggable Multi-Purpose Module PMMAnant Thakar Cisco SystemsAgenda Preamble Why new Form Factor?Use Cases Electro-Mechanical Form Factor Connector Paradigm Shift in ComputingMemory TiersSCMComputational StorageCore ExplosionMemory/IO ScalingBW/Capacity limitationSmartNIC ComputingApplicat

2、ion Specific accelerationNetwork Service offload computing AI/ML WLComputer VisionCognitive Computing Accelerated ComputingGPU/TPU SW on SiliconFPGA/IPU/DPU Memory Tiers DRAM/SCM,Near Memory compute CPU CentricHeterogeneous ComputeHomogeneous ComputeKey Drivers ML/DL Workloads&disaggregation in Data

3、 Center Best of breed domain specific Hardware Leading to Modular server partition InterconnectWhy new Form Factor?Use cases1.sNIC/DPU compute/AcceleratorsTransition from foundation NIC to high power and high-performance network services including MegaNIC applications2.High TDP GPUs 200W-400W+Servic

4、eability and better thermal aspects 3.Memory Cassette -Multi-TB Capacity expansion(e.g x DIMMs with CXL controller)Transition from local dram DIMMs to capacity/Bandwidth expansion Tier 4.Modular Edge compute/Multi Node (CPU+DIMM+Front IO)Standardized Form factor for Edge compute/Multi node/SP market

5、CXL Memory ControllerEDSFF 4CCXL Memory CassetteDPUCPUWhat is a PMM?Working LZ:SFF-TA-1002 like(PCIe/CXL G5/G6/G7)Advanced sidebands USB,KX/KR,PESTI Data IO signal Pairs-2 x 16 Lanes Thermal/Power support up to 200W600W Thickness:can fit in 1U horizontal Length:DIMMs+other components driven Width:xP

6、U+8(min)DIMMs driven Height:QSFP 1T,2T DIMM driven Sponsors:Cisco/Intel/HPEPMM aka Pluggable Multi-Purpose Module defines Electromechanical definition of Module and Host side connector enabling new use cases and as such is new Form factor.PMM Module Mechanical 2T1T230mm125mm38.4m
