One of the leaders in Fibre Channel, stackable switches and blade server switches, QLogic, has announced that its Fibre Channel host but adapters (HBA) drivers are now fully compliant and interoperable with the XenSource Xen Hypervisor.
Hypervisor is an open-source virtualisation software code that will likely be included in the upcoming releases of Linux operating systems such as Red Hat Enterprise Linux 5 and SuSE Linux Enterprise Server 10.
QLogic says that its HBA drivers combined with the virtualisation-enabled OSS will offer end-users the means to establish a fully integrated, reliable virtual server environment and reap the benefits of dramatically increased server efficiency.
The company says that, according to conservative estimates, servers typically operate at 15-20% of CPU capacity; with virtualisation, server utilisation could rise to 80%, which it suggests will allow users to consolidate greater workloads on fewer servers and provide substantial savings in space and power. Additional benefits will include the ability to migrate and isolate workloads in the event of system failure.
The QLogic Fibre Channel HBA drivers include technology for the virtualisation of physical HBA ports that says the company work seamlessly with the Xen Hypervisor and Linux OS kernel.
Comments Amit Vashi, senior director of product marketing, QLogic Computer Systems Group, "QLogic has been working closely with the Linux development community to make virtual server environments a reality and bring the benefits of virtualisation to our customers' data centres."
