Higher education IT executives know that data center consolidation doesn’t always lead to simplification. Instead, in most cases, when you reduce locations, you’re left with a highly complex mess of enterprise components wreaking havoc on your performance.
The successful data center can respond to business requirements without jeopardizing operational and capital costs. Yet, if you’re trying to manage an out-of-control architecture – even if it’s in fewer locations – that goal is unattainable.
Take, for instance, the University of Southern Florida. Michael Pearce, system vice president for IT, says it’s his job to create an open and collaborative environment for the school’s more than 60,000 users across several campuses. What makes this task difficult is that many users have cross-functional roles that give them access to multiple systems. For instance, someone might work at the school’s medical center and also be a student. It’s critical for compliance and other security mandates that this user can’t share information between applications.
Most academic institutions operate a three-tier data center architecture that would require them to manage their switches, routers and other infrastructure individually to gain this kind of control. This is hardly a model for simplification.
Imagine if you could wipe out one of those tiers and flatten your data center architecture. Well, it’s possible if you centralize your data center management and use purpose-built gear that is interoperable and lets you manage the data center as a whole entity – not a mishmash of legacy parts. With this sophisticated, state-of-the-art infrastructure, including switches, routers and security, you can gain IT resilience and optimal performance.
Take for instance, virtual switches. As IDC reports in an executive brief titled “Simplification Driving Datacenter Network Requirements,” virtual switches “will reduce demand for physical switches but place greater need for performance and reliability at the core.”
In addition, IDC contends that enterprises will not migrate their mission-critical workloads to a virtual architecture unless they have the same consistent network security, management and policies available on virtual ports as they do on physical ports. This is certainly true of higher education.
So, even if a virtual switching infrastructure seems promising in terms of allowing you to reduce your overall physical devices, unless you can manage the virtual and physical networks as a logical whole, this endeavor will not hold water.
You need a comprehensive solution that supports a resilient virtual switching fabric. In fact, Yankee Group senior analyst Phil Hochmuth says, “the idea of a fabric – being able to have that failover, that ability to connect quickly and mesh with other nodes in the network – is essential.”
Jeff Kabel, a technical marketing engineer at 3Com, says the key is to be able to take multiple core, distribution and access layer switches and make them look like a single, logical switch. There should be no need for multiple links for redundancy and legacy resiliency protocols. Rather, you have complete physical layer redundancy.
The network control protocols also operate as a cohesive whole to streamline processing, improve performance and simplify network operations. For example, routing protocols calculate routes based on the single logical domain rather than the multiple switches it represents.
In the next blog, we’ll discuss the management methodology that can further simplify your data center.
