NEC White Paper Sample

Server virtualization is clearly one of the breakout technologies in the first decade of the 21st century. The unambiguous value of virtualizing servers comes from the measurable increase in hardware utilization and superior application deployment flexibility, which in turn facilitate highly cost effective server consolidation. The results are both operationally and economically compelling, however, they are not without their pitfalls as server virtualization — unless properly managed — can result in difficulties with SAN storage.

Server virtualization provides highly desirable availability capabilities such as transparent live migration of applications without disruption, live migration of storage volumes without disruption, near instantaneous recovery of down machines at a local or remote site, on-demand allocation of hardware resources based on QoS policies per virtualized guest, and non-stop availability in the event of a hardware failure. These capabilities along with even basic hypervisor functionality necessitate networked storage for hypervisor functionality and ease of management. However, this is where the frustration begins.

NEC eliminates these frustrations with its highly innovative D-Series. Any organization implementing virtualized servers or even just looking to add SAN storage would be well-served to take a hard look at the NEC D-Series.
