I'll focus on delivering an overview that encapsulates the evolution, key models, features, and technical aspects of the zSeries mainframes, along with highlighting available resources and literature where possible.

The IBM zSeries mainframes represent a lineage of enterprise-class mainframes designed for high reliability, availability, and serviceability. Introduced in the early 2000s, the zSeries marks the transition towards 64-bit processing in IBM's mainframe technology, using the z/Architecture. These systems are pivotal for large-scale transaction processing, database management, and batch processing in critical business operations across various industries.

The zSeries mainframes began with the z900 model, introducing the z/Architecture with a 64-bit processing capability. Subsequent models, such as the z990, z9, and z10, continued to enhance performance, scalability, and security features, incorporating IBM's latest technologies such as Parallel Sysplex, RACF, and advanced virtualization with z/VM.

z/Architecture is the foundational technology of zSeries mainframes, enabling significant advancements in processing power and memory utilization. This architecture supports the efficient execution of multiple, concurrent workloads and facilitates extensive virtualization capabilities, making it a robust platform for modern enterprise computing needs.

z/VM stands out as a highly efficient, scalable virtualization environment specifically designed for IBM mainframe systems. It allows for the creation and management of thousands of virtual machines, optimizing hardware utilization and enabling substantial workload consolidation on a single physical machine.

The software ecosystem for zSeries mainframes is extensive, featuring z/OS, Linux on IBM Z, CICS, DB2, and IMS. These software solutions leverage the mainframe's hardware capabilities to deliver unmatched reliability, security, and performance for critical applications and databases.

Each zSeries model brought specific enhancements. For example, the z890 introduced greater flexibility and scalability, while the z10 EC added significant improvements in performance, capacity, and energy efficiency. The introduction of the zEnterprise system further blurred the lines between mainframe and distributed computing environments, offering integrated hardware and software solutions.

Security is a cornerstone of IBM mainframe technology, with features like RACF, digital certificates, and encryption capabilities built into the zSeries. These mainframes ensure the protection of sensitive data and compliance with global security standards, making them ideal for financial institutions, government agencies, and other security-conscious organizations.

IBM zSeries mainframes excel in connectivity and networking, supporting a wide range of communication protocols and interfaces. Technologies like FICON and OSA enhance data transfer rates and network integration, facilitating seamless interaction with both modern and legacy systems.

The design of zSeries mainframes emphasizes high availability and disaster recovery, utilizing technologies such as GDPS for real-time data mirroring and automatic failover capabilities. These features ensure continuous operations and data integrity in the face of unforeseen events.

zSeries mainframes are designed to scale vertically and horizontally, meeting the growing demands of businesses. Tools and technologies like Workload Manager (WLM) and System z Application Assist Processor (zAAP) enable dynamic resource allocation and optimization, ensuring that performance levels meet service level agreements.

The future of zSeries mainframes continues to evolve, focusing on hybrid cloud environments, AI integration, and blockchain technologies. IBM remains committed to advancing mainframe technology to address the changing needs of enterprise computing, highlighting the ongoing relevance and innovation of the zSeries.

While specific books focusing solely on zSeries mainframe models are rare, IBM Redbooks provide invaluable resources on various aspects of mainframe computing. Titles such as “Introduction to the New Mainframe: z/OS Basics” offer insights into the fundamentals, while others delve into specialized topics like security, performance optimization, and application development. Access these resources at the IBM Redbooks website for detailed technical information and guidance.
