SAN MDS (Storage Area Network – Multilayer Director Switch) is a high-performance
switch specifically designed for Storage Area Networks (SANs), where it interconnects storage devices and servers. MDS switches are primarily produced by Cisco under the Cisco MDS 9000 Series brand, and they are engineered for reliability, scalability, and high throughput in enterprise data centers that require robust storage networking.
MDS switches support high- bandwidth, low-latency connections, ideal for demanding storage environments and data-intensive applications like databases, virtualized environments, and large-scale backups.
MDS switches support multiple storage protocols, including Fibre Channel (FC), Fibre Channel over Ethernet (FCoE), and Internet Small Computer Systems Interface (iSCSI), allowing for flexible connectivity and integration with various storage technologies.
SAN MDS switches are modular and highly scalable, making them suitable for expanding storage networks. They can be configured with multiple modules and can scale up to support thousands of ports.
They offer advanced SAN management features such as VSANs (Virtual Storage Area Networks), zoning (which enhances security and traffic control within the SAN), Data Center Network Manager (DCNM) for centralized management, and Inter-VSAN Routing (IVR).
MDS switches are designed for reliability and typically have redundant power supplies, hot-swappable components, and failover capabilities to ensure continuous data access and network resilience.
MDS switches include security features like role-based access control (RBAC), port security, and Fibre Channel security protocols to protect SAN environments.
Cisco’s MDS line includes Cisco MDS 9700 Series Director switches and Cisco MDS 9148 Series Fabric switches, designed to handle heavy SAN traffic loads with advanced management, security, and scalability features. These are commonly used in environments where reliable and scalable storage connectivity is essential.
