Virtual access layer
The virtual access layer (VAL) refers to the virtualization of the access layer that connects servers to the network in the data center. Server virtualization is now aggressively deployed in data centers for consolidation of applications hosted on x86 servers. However, the underlying limitations in current networks prevent organizations from meeting the performance, availability, security, and mobility requirements of server virtualization. VAL is a product strategy that delivers features to address the unintended consequences of server virtualization. It focuses on issues in the server and virtual server I/O, addressing the operational challenges for server, application, and network administrators.
