Sustainable and cost-effective long-term storage remains
an unsolved problem. The most widely used storage technologies today are magnetic (hard disk drives and tape). They use media that degrades over time and has a limited lifetime, which leads to inefficient, wasteful, and costly solutions for long-lived data. This paper presents Silica: the first cloud stor-
age system for archival data underpinned by quartz glass,
an extremely resilient media that allows data to be left in
situ indefinitely. The hardware and software of Silica have
been co-designed and co-optimized from the media up to the
service level with sustainability as a primary objective. The
design follows a cloud-first, data-driven methodology underpinned by principles derived from analyzing the archival workload of a large public cloud service. Silica can support
a wide range of archival storage workloads and ushers in a new era of sustainable, cost-effective storage.
