Multi-Tenant Datacenters


The Colocation Challenge


Multi-Tenant Datacenters and Hosting Facilities allow their customers to enjoy the benefits of a controlled datacenter environment without the time and expense required to lease building space and deploy racking, power and cooling equipment. In addition, they offer direct access to multiple carriers and ISPs and the ability for customers to be part of a connected customer ecosystem.

For facility owners and operators however the challenges of operating and managing these colocated facilities and keeping customers satisfied can be considerable. Many of these challenges are associated with the manual optical fiber connectivity and patching typically deployed. Some of these challenges include:

Time to Provision New Services – It can typically take days to open a service order, create the optical patch between customers or customers and Carriers, verify the patch, & close the service order. This means delayed new service revenue and diminished customer satisfaction.

Operational Expense – An on-site workforce is needed to operate and maintain the manual fiber systems and to execute moves, adds, and changes when new service orders are received. The manual record entry and inventory procedures associated with human intervention are error prone & expensive.

Quality of Service – Manual fault isolation on fiber connections is time consuming, expensive, and can lead to extended customer outages.

How Optical Circuit Switching Solves The Challenge


Optical Circuit Switching solutions such as CALIENT’s S-Series product line offer facility owners the opportunity to automate service provisioning and fault isolation of fiber networks.

Deployed in multiple locations colocated with Intermediate Distribution Frames (IDFs), and Main Distribution Frames (MDFs), optical circuit switches can slash provisioning times from days to seconds and reduce on-site workforce needs. In addition, real-time monitoring and alarming of optical power levels on all entry and exit points in the systems aids fault detection and isolation during service degradation or outages.
