Robust SAN and mainframe connectivity over distance
Deterministic DCI solutions built for simplicity, zero downtime and future‑proof security
High-capacity data center connectivity preserving performance and security
Distributed data centers are vital for mission-critical applications. However, extending networks across sites can degrade application performance and compromise data confidentiality.
Critical workloads depend on geographically distributed data centers to ensure business continuity, data availability and confidence in service integrity. They support applications such as trading and payments that require secure, reliable, high-capacity connectivity across storage, mainframe and data center environments.
Extending connectivity across sites introduces challenges. Distance adds latency and buffering constraints that can degrade SAN and mainframe performance, while data in transit must be protected from unauthorized access to meet stringent regulatory requirements.
Backed by comprehensive qualification programs with leading ecosystem partners, our solutions deliver validated interoperability and are designed to support secure, seamless operations across data centers.
