Metro Storage Cluster

Operate your solution across two sites for near-zero downtime

A metro storage cluster is the perfect solution if disaster, data loss and downtime avoidance are your top priorities. Built with market-leading VMware technology, metro storage clustering allows you to effectively extend your eCloud Private by expanding its local storage and networking across two physically separate locations. This means that should disaster strike at one data centre site, knocking it offline, your operations automatically transfer to the second site in minutes to provide near-zero downtime.

Choose from Manchester or London-based metro storage clustering sites, with long-distance separation supported with our central and west London sites.

How it Works

VMware Metro Storage Cluster (vMSC) is an option which can be added to an eCloud Private environment at UKFast. Our multi-site network is designed to deliver the high bandwidth, low latency connectivity that vMSC needs to work effectively, and provide the benefits of a local high-availability solution with geographic separation.

VMware Metro Storage Cluster combines synchronous replication with array-based clustering. When running a vMSC, your storage subsystems seamlessly span the two data centres, presenting a single and common infrastructure to your VMware vSphere virtual machine layer.

vMSC is recommended where disaster and downtime cannot be tolerated. In other words, it's about seeking to protect your applications and data before a disaster occurs. Combining vMSC with our Advanced Backup with Commvault service can also provide a comprehensive disaster recovery solution.

Multi-Site Solutions

We have the expertise, capability and flexibility to design a multi-site solution that meets your business needs. If our Metro Storage Cluster solution doesn't sound like the right fit, we have a number of alternative solutions which also provide geographic hosting resilience.

Under The Bonnet

VSphere Technology

Your eCloud virtual machine layer runs on VMware's vSphere technology. Metro Storage Clustering creates a single storage subsystem that spans two UKFast data centres, and presents it to your virtual machine layer.

Fibre Channel

Connectivity between your virtual machine layer and vMSC is provided by Fibre Channel, which supports the maximum round trip time of less than 10 milliseconds for vMSC to function as designed.

vMSC Configurations

Various vMSC configurations are possible, talk to our eCloud experts to understand which one is right for you.
