All-Flash Storage System for Ceph and OpenStack

InfiniFlash System IF150, along with Red Hat Ceph Storage software, delivers a massive scale-out, high-performance, all-flash storage system that provides boundless scale, efficiency, and resiliency for Ceph and OpenStack environments.

Introduction

With the growth of mobile, social, big data, and the Internet of Things (IoT), the quantity and variety of data has skyrocketed. SanDisk’s InfiniFlash™ System IF150, along with Red Hat® Ceph Storage software, delivers a massive scale-out, high-performance, all-flash storage system that provides boundless scale, efficiency, and resiliency for Ceph and OpenStack environments.

Technology

InfiniFlash

The InfiniFlash™ System IF150 provides petabyte-scale capacity, high density and performance for OpenStack® and Ceph environments, and delivers dramatic cost advantages for customers with big data storage requirements. The IF150 delivers the performance of an all-flash array with the economics of an HDD-based system. It is the ideal storage choice for medium to large OpenStack deployments, providing very low latency, extreme IOPS, and sustained throughput.

Each system can be configured with up to 64 hot-swappable cards, delivering up to half a petabyte (512TB1) of raw flash storage in a 3U enclosure and up to 6PB in a single rack. The IF150 scales easily as each unit may connect up to eight servers. The Ceph cluster software provides high availability, load balancing, data replication and storage services required by OpenStack solutions.

Red Hat Ceph Storage

Red Hat Ceph Storage is a massively scalable storage platform that uses Red Hat Enterprise Linux® as its underlying operating system. Red Hat Ceph Storage helps businesses to automatically and cost-effectively manage their storage needs, allowing enterprises to focus on data availability. It scales across physical, virtual, and cloud resources, and allows organizations to add capacity as needed without sacrificing performance or necessitating vendor lock-in.

Red Hat Ceph Storage is offered on the IF150—the latest InfiniFlash storage system. Together, SanDisk and Red Hat have worked to bring Ceph storage with unsurpassed performance, providing over a million Inputs/Outputs per second (IOPS).

Features and Capabilities

  • OpenStack integration
  • Red Hat Ceph Storage tuned for maximum performance with InfiniFlash
  • Modular architecture enabling non-disruptive expansion beginning at 64TB up through 512TB in one chassis, and up to 6PB in one rack
  • Low power consumption—only 450 watts typical for 512TB
  • Automatic failover prevents server or module failures from impacting data integrity, availability or performance
  • Striping, erasure coding, and replication across nodes enables data durability, high availability and high performance
  • Achieve ultra-low Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO) with all-flash storage modules
  • Storage policies can be configured to meet service level agreements (SLAs), performance requirements and failure domains
  • Snapshots, thin provisioning and incremental backups
  • Automatic rebalancing using a peer-to-peer architecture, adds instant capacity with minimal operational effort
  • Hot software upgrades
  • Upgrade clusters in phases—adding or replacing cards online—with minimal or no downtime
  • RESTful interface, S3 and SWIFT support

Benefits

  • High-performance storage for OpenStack and Ceph environments
  • Petabyte-scale capacity and high density for OpenStack
  • Cost-effective flash storage that can equal the performance of HDD based systems and public-cloud storage
  • Industry-leading density, yielding rackspace savings from 64TB to 512TB per 3U module
  • Significantly less power consumption than equivalent capacity HDD arrays2
  • More than 10x the reliability (AFR) of HDD arrays3
  • Independent scaling for compute and storage nodes
  • Seamless integration with OpenStack
  • Advanced block and object storage capabilities
  • On-demand, scale-out architecture
