Pure Storage

xiRAID is a high-performance RAID solution designed specifically for modern storage environments, particularly those built on NVMe and NVMe-over-Fabrics (NVMe-oF) technologies. It replaces traditional hardware RAID controllers with a software-based approach that delivers significantly higher performance, lower total cost of ownership, and greater flexibility. It supports both locally attached drives and networked NVMe devices, presenting them as a unified block device that applications can use without modification. It is engineered to achieve near-hardware speeds through advanced techniques such as I/O parallelization and a lockless datapath, enabling throughput of up to 150 GB/s, up to 30 million IOPS, and latency below 0.5 ms while maintaining minimal CPU and memory usage. It supports a wide range of RAID levels, including 0, 1, 5, 6, 10, 50, 60, and 70, and is compatible with POSIX APIs, allowing seamless integration with existing file systems.

AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage. Customers use Storage Gateway to simplify storage management and reduce costs for key hybrid cloud storage use cases. These include moving tape backups to the cloud, reducing on-premises storage with cloud-backed file shares, providing low latency access to data in AWS for on-premises applications, as well as various migration, archiving, processing, and disaster recovery use cases. To support these use cases, the service provides three different types of gateways – Tape Gateway, File Gateway, and Volume Gateway – that seamlessly connect on-premises applications to cloud storage, caching data locally for low-latency access. Your applications connect to the service through a virtual machine or hardware gateway appliance using standard storage protocols, such as NFS, SMB, and iSCSI.
