QStar’s Kaleidos offers an optional hybrid architecture that use disks and tapes (LTO tape library), integrating the two technologies into a traditional Object Storage system. This way customers enjoy the best of both technologies: fast data access (disks) and extremely low operating and storage cost (tape). This hybrid and scalable storage solution can be used to archive unlimited amounts of information securely and cost-effectively.
QStar Kaleidos employs high-density industry standard servers and high capacity disk storage; and is the only object storage provider that integrates tape and commercial cloud as part of the object store, for lowest-cost long term data preservation.
Objects stored in the Kaleidos hybrid architecture are read in precisely the same manner as standard Object Storage protocols, via HTTP, S3, REST API, even though the data is actually stored on tape. Not only are users unaware that the data they are accessing is stored on tape and not on disk, but a sophisticated front-end cache also means that data read/write performance is comparable to that of an Object Storage system.
