The use of server virtualization to drive real server consolidation was one of the major
IT success stories of the past several years in many large and midsize enterprises. IT
staffs won major kudos for reducing costs and boosting responsiveness to end-user
requests for new and expanded applications. Despite this success, however,
extensive use of server virtualization creates challenges for IT departments.

IDC has spoken to countless IT administrators who report that stress on existing
storage provisioning and data protection practices leads to unanticipated spending on
hardware, software, and network products. They often mention that connection of
virtualized servers to existing data networks and SANs increases network/cabling
complexity while also disrupting network performance and reliability.

The digitization of information is also seen as a boon for employees and customers
because the access to content and the move to disk-based data protection boost
productivity and responsiveness while opening up new business opportunities. This
information explosion, however, also creates a new range of problems:

information explosion, however, also creates a new range of problems:
Excessive duplication of data
Spiraling data migration and data replication costs
Concerns about digital data security and privacy
Many companies are looking at a wide array of standalone storage appliances, each
of which targets a specific problem (backup or encrypted data at rest), but IDC has
spoken to many IT executives who worry that such an approach only complicates the
management task. They would prefer a solution that addresses all of these needs
through a common hardware and network foundation.

IDC expects to see greater convergence of diverse network, SAN, and server
interconnect environments across all data center environments. Based on existing
investments, individual organizations will tend to use either 8Gbps FC or 10GbE (e.g.,
FCoE, iSCSI, NFS, or CIFS) networks as the starting point for convergence. The
move toward standard network technologies delivers a number of benefits:

More predictable/reliable network performance
