Instant Storage. Seamless Access. Built for the Future of Mainframe Data.
Zaac by VirtualZ Computing™ is the only no-code solution that delivers both virtual disk and virtual tape storage out of the box — eliminating the cost, delay, and complexity of traditional DASD and tape systems. A versatile solution with many use cases, Zaac enables instant, scalable, secure access to storage across hybrid environments — connecting your IBM Z systems directly to cloud and SAN without rewrites, rehosting, or reconfiguration.
From dynamic storage provisioning to disaster recovery and DevOps enablement, Zaac unlocks a new era of mainframe storage modernization.
Install in Hours. Scale in Seconds.
Zaac delivers on-demand storage where and when you need it:
- Installs quickly with no code or specialized skills
- Requires no hardware upgrades or replatforming
- Works seamlessly with existing mainframe workflows
It’s everything storage should be — instant, intelligent, and integrated.
Zaac Use Cases
Instant Mainframe Storage
Zaac turns cloud or SAN storage into on-demand, plug-and-play storage for IBM Z — instantly.
- Replace aging DASD and physical tape with dynamic cloud-connected storage
- Provision storage capacity as needed — without overbuying or waiting for hardware
- Enable concurrent access to multiple storage environments (e.g., cloud + SAN)
- Eliminate sourcing delays, maintenance windows, and complex config work
Perfect for: Production workloads, storage expansion, and agile storage planning across hybrid environments.
DevOps & Modern Development Workflows
Zaac extends your DevOps strategy into the mainframe — no infrastructure changes required.
- Integrate IBM Z into modern CI/CD pipelines
- Share data between mainframe and distributed/cloud apps
- Enable read-write access to AI-generated or cloud-native data
- Shorten dev-test cycles with flexible virtual storage
Perfect for: Hybrid DevOps, test data management, modern application delivery on IBM Z.
Mainframe Tape to Cloud
Powered by PropelZ™
While Zaac powers instant storage and DevOps use cases, our tape-to-cloud migration solution uses PropelZ — and it’s a vital path to storage modernization.
- Securely migrate decades of mainframe tape data to cloud object storage
- Avoid re-platforming, rewriting, or downtime
- Eliminate costly, hard-to-maintain physical tape systems
Why it matters: Once in the cloud, this historical archive becomes AI-ready — fueling model training, analytics, compliance, and long-term insight generation. What was once locked away becomes a strategic asset.
Business Continuity & Disaster Recovery (BC/DR)
Zaac strengthens your continuity strategy with cloud-based, redundant storage — configured for resilience without complexity.
- Enable automatic failover and recovery across cloud or SAN storage
- Access backup data securely and quickly after outages or disruptions
- Ensure compliance with encryption, duplexing, and role-based access
- Remove the physical constraints and latency of tape-based DR solutions
Perfect for: Enterprises seeking cloud-native DR strategies that support IBM Z without adding risk or retooling.

Purpose-Built for Hybrid Storage and Access
Zaac Extends Mainframe Data Access by Design
Each VirtualZ solution plays a distinct role in modernizing mainframe data access:
- Lozen™ delivers real-time, read-write access to live mainframe data — without moving it
- PropelZ™ securely moves mainframe data to modern platforms for AI, analytics, and compliance
- Zaac bridges storage and access, connecting IBM Z environments with cloud and SAN storage in real time
Choose Zaac when you need to:
- Instantly expand mainframe storage capacity using cloud or SAN
- Allow mainframe applications to access cloud-native or AI-generated data
- Integrate IBM Z into modern DevOps workflows and CI/CD pipelines
- Eliminate sourcing delays, hardware dependencies, and infrastructure constraints
Zaac doesn’t replicate or transform data — it provides dynamic, secure storage that behaves like native DASD or tape. This lets your applications interact with data wherever it lives — without disruption or rewriting.
Bottom line: Zaac modernizes mainframe storage with simplicity, flexibility, and speed — supporting hybrid strategies across enterprise architectures.
