Bus Utilization Q&A Does ULLtraDIMM utilize the memory bus for FTL or other flash management?

– No, Using its embedded processors, ULLtraDIMM performs all flash management on the device itself and only transfers on DDR3 bus after its internal data processing is complete houg.

• Analogous to a host bus adapter

Does the ULLtraDIMM slow down the memory bus – No, but ULLtraDIMM is limited by memory population guidelines (no different than an RDIMM)

– Memory controller will map out a slow device if it does not meet expected performance

– It is possible but can be mitigated by adding more parallel data processing by adding additional ULLtraDIMMs

Can the ULLtraDIMM run slower than optimal under situations where its internal buffer gets saturated?

– It is possible but can be mitigated by adding more devices for additional parallel processing

16

SanDisk BIOS Modification for UlltraDIMMTM Why BIOS modifications are required for UlltraDIMMTM (UD)

– Need to manage UD differently when detected (i.e. not as a standard DRAM) – Memory reservation (E820) and type (MTRR) tables need UD awareness – Initialization of UD hardware – ACPI table updates

BIOS modification guide contains following 4 high-level steps – MRC changes: disable memory test and interleaving of UD – E820 table: UD address space marked as reserved – MTRR table: UD address space marked as write-back – Training Sequence : SanDisk UD Training to be uploaded into UEFI – ACPI table: entries needed to expose UD to the OS device driver

17

CPU Utilization SanDisk is in the process of finalizing the CPU usage based on production level hardware

and software

General guideline is to assign one Hyper thread for Two ULLtraDIMMs (or ~200K to 270K iops max)
