8Gb Fibre Channel Optimized for Virtualized SAN Environments

Short Description
As Fibre Channel (FC) technology evolves into a new generation of 8Gb products, it is imperative that data center administrators deploy a scalable architecture to meet a full spectrum of concerns beyond cost, performance, and backwards compatibility. The modern data center is faced with ever-growing demands in the areas of virtualization, power consumption, reliability, availability, as well as serviceability (RAS), security, and manageability. This paper explores virtualization, one of the key pillars of QLogic’s next generation of FC products that are optimized to exceed the business needs of data centers.

Virtualization has emerged as one of the key technologies that is changing the dynamics of the enterprise data center. The virtualization market space is still in its infancy stages. According to IDC, less than 5% of servers today are virtualized. The following chart from IDC shows the rapid growth of virtual (logical) servers with a Compound Annual Growth Rate (CAGR) of close to 157% from 2005-2010. According to industry estimates, a high percentage (>70%) of the virtualization deployments are attached to Fibre Channel SANs.
Deployments of virtualization today are primarily based on software-based hypervisor technologies such as VMware® ESX Server and Xen™ Hypervisor. Virtualization is becoming mainstream and increasingly being used for production workloads. As the industry makes the transition from physical (non-virtualized) environments to virtualized environments, IT managers will expect the same level of deterministic service delivery in virtualized environments.
