EMC Disk Library for Mainframe – Solution Sizing
A disk library for mainframe solution enables customers to efficiently transport data to a VNX storage system, a Data Domain deduplication storage system, or a VMAX storage system. Sizing is critical to the steady state operation of the DLm. Two aspects of sizing, capacity and performance, need to be considered when designing a DLm solution.

• Sizing for capacity takes into account the total amount of data that a customer plans on storing on the DLm.
• Sizing for performance considers the customer’s backup windows and RPO’s.

This paper will provide guidelines for both aspects of the sizing exercise.
