Best Choices

In today’s highly-competitive, constrained economy most companies need the flexibility to pick and choose the best combination of compute, storage, networking and management options to achieve the organisation's IT goals. When resource choices of the data centre (DC) are limited, IT often cannot choose the best equipment to meet their requirements. In certain environments, a company's corporate IT policy may require specific branded items for all network connectivity. The Cisco Nexus B22 Fabric Extender for Flex System offers choice for clients who require Cisco connectivity for the Lenovo® Flex System Chassis.

With the addition of the Cisco Nexus B22 Fabric Extender for Flex System, companies relying on a Cisco-only Unified Fabric network topology are now free to choose Lenovo Flex System server and storage configurations that are the best choice for the workloads you need to run. You can get the extraordinary choice and flexibility of Flex System compute power, storage capability and networking solutions in a next-generation chassis that is designed for the next decade of DC technologies.
