Why use CAStor Object Storage?

Easy Installation

The CAStor boot image contains the appliance OS, server code and boots directly on bare metal from a USB key or from a network using PXE. The process is straightforward, simple and no software is written to a hard drive, which means drives are symmetric, interchangeable and any type or size of drives can be used.

Automated Management and Maintenance

CAStor includes unrivaled automation for management and maintenance that enables plug-and-play expansion, instant provisioning, automated storage balancing and no-downtime hardware retiring and upgrades. One system administrator without specialized storage expertise can easily manage multiple petabytes of storage.

Rapid Recovery

A health monitor continuously checks data integrity, cardinality (number of copies), and hardware status. If an issue is detected, all available servers in CAStor aid in the recovery. This means that recovery times decrease the larger the CAStor object store grows which reduces exposure to data integrity issues.

Governance and Compliance

Policy-based replication and duration can be set per object and is automatically enforced. Users also have the option to leverage Caringo Content Router to enable high availability options to safeguard data by mirroring between object stores powered by CAStor in one or many distributed locations.

Significant Savings in Disk Utilization

CAStor utilizes up to 98% of disk capacity by removing the inefficiencies of file systems. Enterprise-grade integrity can also be achieved with as little as 2 replicas, saving over 30% in hard drive costs and data center space when compared to Swift.

Adaptive Power Consumption

CAStor includes patent-pending adaptive power conservation technology – Darkive™ – that monitors storage system operations and automatically spins down disks and reduces CPU utilization. Darkive can save up to 35% in power and cooling costs when factored into the overall storage infrastructure.
