It is important to match the number of slots that your library has to the number of retention policies that you have. We disaggregate the three levels of automation to enable you to make the right choices in chassis.
-
Entry Level (Autoloaders): Small 1U or 2U boxes with 8 to 24 cartridges are best suited to small companies that require not only simple and automatic backups but also a nightly backup system without the complexity of full datacenter management.
-
Mid-Range (Modular): A real lto tape library lets you add expansion modules, add slots and drives in small steps, preserving your original investment and growing with the increase of the data.
-
Enterprise Class: It has a dedicated enterprise tape library that has hundreds of slots, a redundant power supply, and hot swappable drives designed to meet the 24/7 datacenter needs of zero downtime.
The choice of the right robotic tape library will make sure that you do not experience premature obsolescence. A chassis of an appropriate size expands with you, transforming capital expenditure into a long-term investment, instead of a short-term shot in the foot. You can have eight slots or eight hundred to match the hardware to your backup window; a costly overhaul in the future will be avoided.
