Abstract

Power outages and subsequent recovery are major causes of service downtimes. This issue is amplified by the ongoing trend of steadily growing in-memory state of Internet-based services which increases the risk of data loss and extends recovery time. Protective measures against power outages, such as uninterruptible power supply are expensive, maintenance-intensive and often fragile. With the advent of non-volatile random-access memory (NVRAM) provided by commodity servers, there is a scalable, less costly and robust alternative to recover from power outages and other failures. However, as of today, off-the-shelf software is not ready for benefiting from NVRAM. We present NV-Hyper visor a lightweight hyper visor extension that transparently provides persistence for virtual machines. NV-Hyper visor paves the way for utilizing NVRAM in virtualized environments (i.e., infrastructure-as-a-service clouds) and protects stateful services such as key-value stores and databases from data loss and time-consuming recovery.
