Standardizing Storage Clusters

Thermal Modeling of Hybrid Storage Clusters

There is a lack of thermal models for storage clusters; most existing thermal models do not take into account the utilization of hard drives (HDDs) and solid state disks (SSDs). To address this problem, we build a thermal model for hybrid storage clusters that are comprised of HDDs and SSDs. We start this study by generating the thermal profiles of hard drives and solid state disks. The profili...

Garbage Collection for Storage-Oriented Clusters

Curator: Self-Managing Storage for Enterprise Clusters

Modern cluster storage systems perform a variety of background tasks to improve the performance, availability, durability, and cost-efficiency of stored data. For example, cleaners compact fragmented data to generate long sequential runs, tiering services automatically migrate data between solid-state and hard disk drives based on usage, recovery mechanisms replicate data to improve availabilit...

Object Storage: Scalable Bandwidth for HPC Clusters

This paper describes the Object Storage Architecture solution for cost-effective, high bandwidth storage in High Performance Computing (HPC) environments. An HPC environment requires a storage system to scale to very large sizes and performance without sacrificing cost-effectiveness nor ease of sharing and managing data. Traditional storage solutions, including disk-per-node, Storage-Area Netwo...
