Rclone is a command-line program to manage files on cloud storage. It is a feature-rich alternative to cloud vendors' web storage interfaces. Over 40 cloud storage products support rclone including S3 object stores, business & consumer file storage services, as well as standard transfer protocols. Rclone has powerful cloud equivalents to the Unix commands rsync, cp, mv, mount, ls, ncdu, tree, rm, and cat. Rclone's familiar syntax includes shell pipeline support, and --dry-run protection. It is used at the command line, in scripts, or via its API. Rclone really looks after your data. It preserves timestamps and verifies checksums at all times. Transfers over limited bandwidth; intermittent connections, or subject to quota can be restarted, from the last good file transferred. You can check the integrity of your files. Where possible, rclone employs server-side transfers to minimize local bandwidth use and transfers from one provider to another without using the local disk.

Open iT StorageAnalyzer™ monitors and analyzes disk, file system, and backup usage to help organizations optimize storage resources and reduce IT costs. It identifies unused, stale, or unnecessary data that can be deleted or moved to lower-cost storage tiers by tracking file age and activity. Detailed reports broken down by user, project, department, business unit, and file type give administrators clear visibility into exactly where storage is being consumed and by whom. StorageAnalyzer™ also supports accurate IT chargeback by attributing storage costs based on actual measured usage rather than flat-rate estimates. By surfacing capacity trends and bottlenecks across on-premises, cloud, and hybrid environments, it enables proactive storage management, prevents unexpected capacity issues, and supports better planning for future storage investments.

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.
