The Case for Replication-Aware Memory-Error Protection in Disaggregated Memory | | Haris Volos
; | | Date: |
1 Sep 2023 | | Abstract: | Disaggregated memory leverages recent technology advances in high-density,
byte-addressable non-volatile memory and high-performance interconnects to
provide a large memory pool shared across multiple compute nodes. Due to higher
memory density, memory errors may become more frequent. Unfortunately,
tolerating memory errors through existing memory-error protection techniques
becomes impractical due to increasing storage cost. This work proposes
replication-aware memory-error protection to improve storage efficiency of
protection in data-centric applications that already rely on memory replication
for performance and availability. It lets such applications lower protection
storage cost by weakening the protection of each individual replica, but still
realize a strong protection target by relying on the collective protection
conferred by multiple replicas. | | Source: | arXiv, 2309.00304 | | Services: | Forum | Review | PDF | Favorites | |
