The demands on the data center look nothing like they did 10 years ago, yet the lion’s share of data center IT spend is plowed into supporting legacy infrastructure.
Up to 70 percent of data center IT spending goes to legacy infrastructure, according to a recent white paper by Alcatel-Lucent (News - Alert) Enterprise on how it and QLogic Technologies have teamed to provide a virtualized and converged network for enterprise data centers that delivers a singular, unified infrastructure for networks, servers, storage and applications.
“A virtualized network platform allows IT to view all resources from a higher logical level, enabling improved asset utilization, which in turn enhances operational performance,” noted the white paper. Ethernet is the technology best suited for the task, but advanced technologies also need to be enabled and interoperate.
Specifically, Alcatel-Lucent recommends a converged data center architecture that reduces capital and operational expenditures by enabling hardware consolidation through adoption of an end-to-end Converged Ethernet network for LAN/SAN transport, network utilization maximization while providing end-to-end lossless channel for SAN traffic, simplification of IT, and CNA NPAR technology that allows for higher NIC (News - Alert) utilization, in turn reducing adapter attachment rates and lowering cabling costs.
Such a setup also will provide:
- Simplified deployment and management through concurrent support for Ethernet, FCoE, and iSCSI, easing deployment and minimizing maintenance disruption.
- Improved ability to scale virtualization through a virtualized platform enabled with Virtual Chassis technology.
- A multipath MESH which facilitates deploying scalable, geographically dispersed data centers.
- High I/O performance in virtualized environments.
For the network virtualization piece their advice is to look to Alcatel-Lucen’ts OmniSwitch. “The OmniSwitch virtualizes the network infrastructure and can support the transport of both IP and lossless storage protocols, such as iSCSI or FCoE,” noted the authors. “This convergence simplifies the datacenter and ensures the longevity of existing IT investments. Servers can connect to any network element using a CNA that carries storage and data traffic (IP) simultaneously over a single interface.”
The goal is to accelerate the days of legacy data center equipment are relied upon by the Enterprise, and recent reports showing an increase in cloud adoption by enterprises highlights how rapidly the landscape is transforming.
