Scalable Memory System


2/14

Clustered Servers:

Distribute dataset across manyservers to increase performance

Insufficient Memory!

Drive Arrays:

Distribute & replicate data acrossmany disk arrays

Multi-core Servers:

Virtual machines to reducecost, power & space

Scalable Memory: FB-DIMM?

1 Step Forward, 2 Steps Back2. Power InefficiencySerial interconnect active on all hopsAll DRAM in high power state: 5WBuffer (AMB): 5-7W (heat-sink needed)

6. Scale Limitations8 Modules per ChannelController channel limitsSystem power limits36 memories per DIMM

Intel/JEDEC Standard $200MM invested

1. Serial InterconnectReduces pin & trace countsAllows more DIMMS per channel

64GByte per system

3. Additional LatencyAll commands repeated

through N hopsSkew between lanes

5. Reliability IssuesBuffer failure= channel failure= crash!Buffer heat decreases memory MTBF

4. Poor FlexibilityOnly DRAM RAS/CAS on serial!Same speed/grade per channel
