Fabric-Based Infrastructure and Cisco UCS
A good segue to Fabric-Based Infrastructure is Gartner’s Magic Quadrant for Blade Servers (March 2012), by Andrew Butler and George Weiss. To fully understand the tie in with Fabric-Based Infrastructure I suggest reading the section on Cisco UCS. Their observations are important because they tie directly to the subject of this blog. You will also get a better feel for why Cisco UCS is having such rapid customer adoption worldwide.
The emphasis for Fabric-Based Infrastructure is delivering value-add functionality that enables data centers to operate more efficiently and cost effectively. A good place to start is by looking at this Gartner report by George Weiss and Donna Scott -- Fabric-Based Infrastructure Enablers and Inhibitors Through the Lens of User Experiences (April 2012). In this short research note, George and Donna go into the key drivers and reasons for the FBI architecture and the benefits that their clients have seen. My take away for the key benefits of Fabric-Based Infrastructure are:
- OpEx and CapEx savings
- Increased VM density
- Time-To-Deploy reduced from months to hours via automation and standards implementation;
- Reduce cost and complexity and improve agility;
- Improved resiliency by recreating servers and connectivity in minutes using profiles and templates
While reading about a technology innovation is helpful, actually listening to experts discuss the architecture and give their individual perspectives can be more so.
I suggest that you make time to listen to this 34 minute video with featured guest Donna Scott (a VP and Distinguished Analyst at Gartner) and Paul Perez (VP and CTO for the Data Center Business Group at Cisco Systems) -- Fabric-Based Infrastructure (FBI) in Today’s Data Center. Donna looks at the motivations and impact of customers moving to a Fabric Based Infrastructure with an eye toward what is important to adopters. Then Paul discusses Cisco UCS innovations and how they let FBI adopters achieve their goals. If you would like, you can download a podcast of the video from theCisco Analyst Reports page.
From my perspective the truly compelling part of this story is the extent to which Cisco UCS makes the promise of Fabric-Based Infrastructure a reality, while emphasizing safety, security and the risk reduction. These are critical considerations in today’s IT environment. Cisco continues to be a key innovator in data center technology and is continuing to grow from strength to strength, delivering value and benefit for your long term application solution needs.
Below is how I think a Fabric-Based Infrastructure should look. Of course I am predisposed. Cisco UCS architecture provides the ability to define and manage over 120 different server identity parameters via service profile templates, using a native tool with Roles Based Access Controls and across geographies. UCS enables you to have a distributed environment that is centrally managed. Your admins can also use CLI, custom designed tools / scripts, or third party tools as they choose to meet the needs of their current management structure.
Fabric-Based Infrastructure (FBI for short) for me is really about how IT departments can abstract server identities from the physical hardware, making it easy to duplicate and automate server identities at scale, minimizing errors, work and complexity and do it FAST. Fast is important because downtime and long Recovery Time Objectives (RTO) can severely impact business performance and profitability. FAST requires service profiles and templates that let you leverage existing server configurations and connect to the LAN and SAN environments as an integrated, natural part of the task. The key is to:
- Provide compute resources (servers) when and how your applications and business needs them;
- Provide a repeatable and dynamically scaling method to deliver compute capacity quickly;
- Promote collaboration between administrators for faster service delivery;
- Address your needs economically – capture actual quantifiable benefits; and,
- Do it all quickly and easily.
Your data center administrators must be able to consistently apply server identity parameters, networking, QoS, security, and compliance on a holistic basis, regardless of location for any physical server or whether the target is a blade or a rack optimized server. This is beyond what can be done with hypervisors and should include I/O management features.
To fully utilize Fabric-Based Infrastructure design, you must also be able to manage your I/O within a unified infrastructure. Cisco VM-FEX collapses virtual and physical networking into a single management architecture that lets you: provision, configure, manage, monitor, and diagnose virtual machine network traffic and bare metal network traffic in a single unified infrastructure. Using Cisco VM-FEX technology can eliminate the need for a virtual hypervisor switch completely, freeing up processor cycles by eliminating virtual switch overhead.
The full list of Fabric-Based Infrastructure enablers are high value-add benefits on which Cisco UCS delivers. If you have to do this by adding multiple tools, consoles, and databases, which must be hosted, managed, updated and maintained separately, you just increase cost and complexity, while increasing risk.
