Introduction 1. Intel® RAID Portable Cache Module AXXRPCM3 Technical Product Specification Introduction This document specifies the key hardware components, firmware, and software utility requirements for the Intel® RAID Portable Cache Module AXXRPCM3. The Portable Cache Module is available as an accessory for the Intel® RAID Controller SRCSASJV to provide data integrity for the RAID solution by ensuring that the data passing through the cache is written to the hard drives.
Intel® RAID Portable Cache Module AXXRPCM3 Technical Product Specification Introduction Portable Cache Module and the associated hard disk drives to a replacement Intel® RAID Controller SRCSASJV, the Intel® RAID Portable Cache Module AXXRPCM3 flushes the unwritten data preserved in the cache to the disks through the new adapter.

Hardware Intel® RAID Portable Cache Module AXXRPCM3 Technical Product Specification Table 3. Pin Descriptions Pin CK, CK1 Type Input Function Clock: CK and CK1 are differential system clock inputs. All address and control inputs are sampled on the crossing of the positive edge of CK and negative edge of CK1. Output (read) data is referenced to the crossing of CK and CK1 (both direction of crossing).
Intel® RAID Portable Cache Module AXXRPCM3 Technical Product Specification Type Hardware Pin SCL - SDA - SPD Data: This bidirectional pin is used to transfer data into or out of the SPD EEPROM. A resistor must be connected from the SDA bus line to VDDSPD on the system planar to act as a pull-up. SA0 – SA2 SUPPLY SPD Address Lines: These signals are tied at the system planar to either VSS or VDD SPD to configure the serial SPD EEPROM address range.
Hardware Intel® RAID Portable Cache Module AXXRPCM3 Technical Product Specification Measures charge flow using a V-to-F converter with offset of less than 16 μV after calibration The Texas Instruments bq2060A SBS-compliant Gas Gauge IC* for the battery pack maintains an accurate record of the available charge. It determines battery capacity by monitoring the amount of charge input or removed from the smart battery.
Intel® RAID Portable Cache Module AXXRPCM3 Technical Product Specification 2.5.2.1 Hardware Initialized State The battery is in the initialized state during a normal power-up sequence. In RAID firmware, there are two levels of initialization: During boot loader execution During RAID firmware boot 2.5.2.2 Discharging State The battery voltage is drained as part of a relearn cycle. 2.5.2.

Intel® RAID Portable Cache Module AXXRPCM3 Technical Product Specification Intel® RAID Smart Battery Software 4. Intel® RAID Smart Battery Software 4.1 Intel® RAID BIOS Console 2 The system BIOS loads the RAID option ROM that is resident on the RAID controller flash. This utility is initiated by pressing + when prompted during POST (Power On Self Test). The option ROM checks for the presence of the battery and informs the user if the battery is missing or not fully charged.
