DCI Use Case: Capacity Expansion

Hi,

Today I want to bring up DCI use case that I’ve been thinking about: capacity expansion.  As you know, the purpose of DCI is to connect two or more Data Centers together so that they share resources and deliver services.  The capacity expansion use case is when you have temporary traffic bursts, cloud bursts, either planned or unplanned, maintenance windows, migrations or really any temporary service event that requires additional service capacity.

To start addressing the challenge of meeting these planned and unplanned cloud burst and capacity expansion requirements, check out the new ACE + OTV feature called Dynamic Workload Scaling announced recently.

What Cisco’s New Data Center Switching Announcements Mean for Service Providers

Cisco’s foundation for delivering the service provider Cloud is our Unified Service Delivery (USD) solution, featuring tightly integrated, data center and IP NGN technologies to deliver a virtualized end-to-end infrastructure for cloud services. We thought it would be useful to share some new capabilities that Cisco has added recently to the solution:

MPLS in the Data Center: To streamline the end to end operation across the data center and IP NGN,  Cisco announced, last week, that Nexus 7000 supports Multi Protocol Label Switching (MPLS) for Layer 3 virtual private networks (VPNs). This allows MPLS to be deployed  at the data center core/aggregation layer  rather than terminating at the data center edge. This capability enables Service Providers to greatly simplify L3 segmentation, especially for multi-tenant cloud offerings, depending on their scale and service needs.

Another key to the delivery of a data center built for Cloud requirements of scale, virtualization and multi-tenancy has been the use of a Unified Fabric. Unified Fabric provides the flexibility of high performance, highly available networks to support the needs of both LAN and SAN on a consolidated fabric. Cisco’s Unified Fabric announcements last week bring new capabilities which extend our already robust offerings to further build out a Service Provider Cloud foundation.

Announcing True Director-Class Multihop FCoE

March 30, 2011 at 6:49 am PST

For months people have been asking me what I’m doing, and it’s been difficult to hold something like this under my hat because I’ve been really excited about this.

How the time has flown. I joined Cisco in June of last year, and on my first day my manager told me that I was going to be working on a new product -- an FCoE blade for the MDS 9500 Series Fibre Channel Directors. Read More »
