Overview 1. Intel® RAID Smart Battery AXXRSBBU3 Technical Product Specification Overview This document describes the key hardware components, firmware, and software utilities for the Intel® RAID Smart Battery AXXRSBBU3. The Smart Battery AXXRSBBU3 provides data integrity for the RAID (Redundant Array of Inexpensive Disks) solution by ensuring that the data passing through the cache is written to the hard drives.
Intel® RAID Smart Battery AXXRSBBU3 Technical Product Specification Overview Software: This monitors and informs the user of any issues or actions for the Intel® Smart Battery AXXRSBBU3. Monitoring is accomplished through the Intel® RAID BIOS Console 2, Intel® RAID Web Console 2, or Intel® RAID Command Line Tool 2 utilities. Figure 1.
Overview Intel® RAID Smart Battery AXXRSBBU3 Technical Product Specification The battery pack cache-memory hold time depends on the size and configuration of the RAID controller/module memory. Retention time depends on memory capacity and the number of memory components on the DIMM to support the capacity. Estimated battery backup retention time is up to 72 hours (three days) for 128 MB memory. Revision 1.
Intel® RAID Smart Battery AXXRSBBU3 Technical Product Specification 2. Hardware 2.1 Electrical and Mechanical Details Hardware The battery pack is rated at a nominal voltage of 3.7 V with a typical capacity of 1050 mAH. Table 1.
