ArmorCache Write Cache Data Protection
ArmorCache Write Cache Data Protection
3 PagesWestern Digital’s ArmorCache software solves the long-standing trade-off between performance and data protection by combining DRAM write caching with a non-volatile flash-backed cache, so systems no longer have to choose between write cache enabled or disabled modes. When data is acknowledged to the host, ArmorCache quickly stages it in DRAM and then safely offloads it to onboard flash in the event of unexpected power loss, preserving both in-flight and cached writes without sacrificing throughput. This intelligent firmware design delivers high performance and robust write cache data protection for demanding enterprise workloads.
