DTS Software

DTS Software is a mainframe storage optimization provider that helps large enterprises manage, automate, and optimize their IBM Z data storage infrastructures. Acquired by Precisely in March 2025, the company serves industries such as insurance, banking, financial services, and retail, where mainframe workloads remain critical. Its tools are designed for organizations that need to reduce production failures caused by disk space shortages, modernize legacy COBOL applications, and enforce smarter dataset allocation policies across complex z/OS environments. The acquisition by Precisely expanded the latter's data integrity portfolio, combining decades of mainframe expertise with DTS's specialized storage management products.

DTS's product suite includes five core capabilities. The Space Recovery System eliminates production failures caused by insufficient disk space by automatically reclaiming unused or fragmented storage. The Allocation Control Center gives administrators full control over dataset creation and placement on IBM Z, enforcing policies that prevent misallocation and improve performance. The COBOL Migration Manager identifies active COBOL programs in production, enabling targeted modernization without disrupting running workloads. The SCC Monitor tracks disk usage by application, alerts when thresholds are breached, and automates reporting to prevent capacity crises. The Simulate 2000 tool provides multiple clocks and alternate timestamps for subsystems like CICS, IMS, or z/OS, supporting testing and compliance scenarios.

In the mainframe storage optimization market, DTS competes with Keepit (cloud backup and recovery), Condusiv (I/O optimization), Cirrus Data Solutions (data migration), Tuxera (file systems), ScaleArc (database load balancing), and Atlantis Computing (hyperconverged storage). Unlike these rivals, DTS focuses exclusively on mainframe environments, offering deep integration with IBM Z subsystems rather than general-purpose storage or backup. Its acquisition by Precisely strengthens its go-to-market reach, but also ties its roadmap to a larger data integrity platform that includes data integration, quality, and governance tools.

The honest trade-offs: DTS is not a general-purpose storage tool—it only addresses mainframe storage, so organizations without IBM Z workloads will find no value. Its pricing starts at $49.00 per month, which may be low for individual features but can scale significantly for enterprise deployments with multiple subsystems. The COBOL Migration Manager only identifies active programs; it does not automate the actual migration or refactoring. The Simulate 2000 tool's alternate timestamping may introduce compliance complexity if not carefully audited. Finally, as part of Precisely, future development priorities may shift toward integration with Precisely's Data Integrity Suite rather than standalone innovation.
