Sometimes it’s difficult to make a significant storage decision, simply because you don’t know the future…other than the certainty that data will continue to grow.For small and medium-sized businesses or branch offices, Quantum addresses this issue with Capacity-on-Demand (CoD) scalability: a powerful feature included in the DXi4601 deduplication appliance and Scalar® i40/i80 tape libraries. Adding capacity is as easy as pushing a button—a mouse button, that is. You purchase just what you need today and simply add capacity later, at low cost and hassle-free.
Most other manufacturers claim to be scalable as well, because customers need to plan for the future, and scaling storage capacity is key to any plan. But take a look under the hood, and it’s easy to see the difference.
First, consider disk-based appliances: Some manufacturers ask you to swap out hard drives for larger capacity ones. But how do you migrate your data from the old drives? Other vendors ask you to add an expansion module, in a separate enclosure, requiring additional considerations for rack space, power, airflow, perhaps a new installation service, and certainly a new service contract. Still other vendors even ask you to purchase a whole new appliance, with the same considerations as an expansion module.
Quantum’s Capacity-on-Demand solution is much simpler. When you buy a DXi4601, all the hard disks are included, for up to 12TB of usable, deduplicated storage capacity, but you only pay for the capacity you need today. When you need to increase capacity, say from 4TB to 8TB, you simply purchase and activate a software license key and the additional 4TB capacity is available—instantly.The situation is similar with tape libraries. If you need to increase the number of slots in your library, other manufacturers make you stack a module onto your existing library, then set up a complicated and failure-prone mechanism to pass tapes from one part to the other, if they offer scalability at all.
With Quantum’s Scalar i40/i80 libraries, all the slots are in the library when you buy it. You simply activate a license key to release the additional slots when your storage needs grow.
Clearly, Quantum’s Capacity-on-Demand is a better solution. This approach simplifies the purchasing decision by enabling you to focus on what’s needed today. With the simplicity of adding non-disruptive capacity tomorrow, extending the life of the product and lowering your total cost of ownership, now you can get back to your other important tasks.
