WHAT’S HOT the bigger truth
At enterprise organizations, keeping an eye on network health, security, and performance is a big job.

equipment through the limited ports; - Performance issues in which network and security tools can’t keep up with the network throughput from 10GbE SPAN/mirror port feeds; - Insufficient time to provision SPAN/mirror ports or network taps/ collectors, which sometimes creates issues for IT groups requiring real-time network visibility.
Intelligent Management Aggregation Networks Some organizations are leveraging a relatively new technology we at ESG call an “intelligent management aggregation network,” or iMAN (sometimes known as a matrix switch or a traffic visibility network).
Conceptually, iMANs make sense but have remained “niche products” thus far. Given the pace and scope of networking changes, however,
Big Changes
A new research report from ESG called Data Center Networking Trends reveals that enterprise data center networks have entered a period of rapid, massive change centering on:
Widespread data center consolidation. Sixty-three percent of organizations with more than 1,000 employees have consolidated or are consolidating their data centers—by as much as 50%. Nearly half of them are converting data centers “owned by” various business units into multi-tenant facilities.
The upshot: Some corporate IT environments are starting to resemble those of service providers.
Increasing server virtualization. Nearly all large organizations use server virtualization solutions from Citrix, Microsoft, VMware, and others. These users are now instituting additional virtualization initiatives, which may double VM deployment in the next few years.
VM densities will rapidly increase as well, growing from 5 to 10 VMs per physical server to more than 20 per physical server in the next 24 months.
Wider web application deployment. So far, 25% of large organizations have deployed SOA or web-based applications “extensively.” Another 60% have done so to a lesser extent.
These applications, which are based on numerous x86 server tiers and horizontal scaling, have spurred significant increases in server deployments and VM mobility.
It’s also notable that about 40% of organizations are extending applications to run across geographically distributed data centers, creating a cloud computing “on-ramp.” Workloads and application elements migrate across these data centers based on fluctuating capacity, performance, and operational demands.

iMANs could become pervasive, transforming into a mainstream enterprise network architecture component over the next 18 to 36 months.
That points to substantial growth for iMAN vendors such as Anue, APCON, Gigamon, Net Optics, and VSS Monitoring. They could become iMAN market leaders, but we also expect to see acquisition activity as larger players in the space - Cisco, HP, Juniper, and others - jump in.
Regardless of how the iMAN market unfolds, it is going to change. Our data points to a strong correlation between future network scaling needs and iMAN market maturity -MAN may well become an enterprise networking staple.
