#627 Shared Unix Hosting - C-Panel Shared Web Hosting Statement - Updated Friday, February 22, 2008

Dear customers,
Emergency work is now underway to migrate our cPanel services to the new storage area network. Due to the re-occurrence of a fault affecting the existing storage network, we have taken the decision to begin the migration process right away as this move, although slightly ahead of our planned upgrade schedule, will result in the best possible service in the shortest time. However, the work will mean extended outages for servers undergoing migration as the data transfer and re-configuration activities take place. Currently, cPanels 05 and 08 are offline and are undergoing the migration work. Please consult the service alert here [url=http://status.zensupport.co.uk/index.php?serviceid=13&incidentid=870]http://status.zensupport.co.uk/index.php?serviceid=13&incidentid=870 [/url] for more detailed information.
The new storage area network (SAN) for cPanel is an entirely new platform designed and built from scratch in response to the outage period that affected cPanel customers in July last year. This new SAN, as well as being new infrastructure using components assembled from more dependable vendors, also offers a number of key technical design benefits:
Improved data throughput - up to 4Gbps theoretical throughput, compared to 1Gbps theoretical throughput on the existing system - a 4 fold improvement
Resilient network connectivity with dual path network links and two independent switched network fabrics to the disk storage arrays from the cPanel servers
More resilient disk arrays utilising RAID1+0 disk arrays, as opposed to RAID5 arrays on the existing system. This provides faster disk performance and enhanced reliability for customer data
I would like to extend my sincere apologies to customers for the inconvenience already caused by this work and the further outages it will necessitate.
